Edit this paragraph 1. seed of a tree

Cinnamomum camphora alias: Cinnamomum camphora is a representative tree species of subtropical evergreen broad-leaved forest, and it is an important timber and special economic tree species in subtropical region (southwest region).

Edit paragraph 2. morphological character

Cinnamomum camphora is an evergreen tree of Lauraceae. As high as 50 meters and hundreds of years old, it is a towering old tree and an excellent landscaping tree. Bark is green and smooth when it is young; It gradually becomes yellowish brown or grayish brown longitudinal crack when it is old. Winter buds are oval. The leaves are thin leathery, ovoid or elliptic-ovoid, 5 5- 10/0cm long and 3.5-5.5cm wide, with short tip or near tail tip, rounded base, three veins from the base, the first or second pair of lateral veins near the base are long and protruding, the back is slightly covered with white powder, and there are glandular points in the axils of the veins. Yellow-green flowers, spring flowers, axillary panicles, small and numerous. Morphological characteristics of spherical Cinnamomum camphora (1 1) The fruit is dark purple after ripening, with a diameter of about 0.5 cm; The flowering period is April-May, and the fruiting period is August-165438+1October. The taupe bark has fine longitudinal cracks in the deep groove. The whole camphor tree has a fragrance similar to camphor, which can repel insects and will never disappear. The leaves are alternate, papery or thin leathery, and the trunk has obvious longitudinal crack, which is very easy to identify. It is said that it is of great significance because there are many lines on camphor wood. So add a wooden character next to the word "Zhang" as the name of the tree. Camphor tree is an evergreen tree. Its evergreen is not deciduous, but after the new leaves grow in spring, the old leaves began to fall off last year, so it presents a scene full of green all year round ... Cinnamomum camphora's florets are very unique, with 6 flowers on the periphery that are difficult to distinguish between calyx or petals, and 9 stamens in the center, each arranged in 1 round.

Edit paragraph 3. control of insect

1. Powdery Mildew: This disease mostly occurs in nursery seedlings. When the temperature is high and humidity is high, the seedlings are too dense. It is most likely to happen in poor ventilation. Gray-brown spots appeared near the main vein on the back of tender leaves, and then spread all over the back of leaves, and a layer of white powder appeared, and there were also white powder on serious tender branches and stems. Prevention and control method: 1. Nursery should always pay attention to environmental sanitation and properly sparse seedlings; Or if a few diseased plants are found, they should be pulled out or burned immediately. 2. When it happens, spray the lime-sulfur mixture with Baume of 0.3-0.5 degrees every 10 for three or four times continuously. Second, it is easy to happen when the seeds of Cinnamomum nigrum germinate and grow 1-4 leaves. From the tip of the seedling to the root, it turned dark brown and died. Prevention and control methods Disinfect seeds, soil and mulch when sowing. At the onset, the burned seedlings should be pulled out first and sprayed with 0.5% potassium permanganate or formalin for two or three times to prevent the spread. Third, the camphor sawfly occurs for many generations a year, and the damage period is long. 1 year-old seedlings were seriously damaged and died. After afforestation, the young leaves in the upper part of the crown are often eaten up, which seriously affects the growth of trees. Control method: 0.5 kg of Flos rhododendri mollis or tripterygium wilfordii powder can be added with 75- 100 kg of clear water to make liquid medicine spray seedlings, or spray 2000 times of 90% trichlorfon or 50% marathon emulsion. Four, camphor leaf roller moth occurs several generations a year, and its larvae gnaw at branches, which affects the height growth of camphor tree and leads to the bending of trunk. Control method: After the new shoots of Cinnamomum camphora are extracted in June and March, the first generation larvae are sprayed with 90% trichlorfon, 50% Nale EC and 50% Marathon EC 10000 times, every 5 days 1 time, for 2 or 3 times in a row, which can kill the larvae. If the larvae have eaten new buds, 40% dimethoate emulsion can also be sprayed 200-300 times. 2. Nursery or small forest land can be collected and burned in winter to eliminate overwintering pupae. Five, Cinnamomum camphora is generally harmful to camphor tree seedlings and young trees under 20 years old. There are two generations in a year. The damage period of the first generation larvae is from the end of May to the middle of July. The second generation larvae were destroyed in August-September. Larvae gather in groups on the new shoots to feed on leaf buds, and spin silk to roll up the residual leaves and wrap the terminal buds, so that the new shoots die, or even the whole plant dies. Control method: 1. When the larvae just start to move and have not yet formed a net nest, 90% trichlorfon can be killed by spraying 4000-50000 times of liquid. 2. If the larva has formed a net nest, it is best to plant it and burn it. Vi. Anoplophora camphor tree 1, during the spawning period of adults (from early May to early June), use lead wire to brush the spawning marks, puncture the eggs or newly hatched larvae. 2. Manually cut off the injured branches, and then inject dichlorvos and other drugs through the drainage holes to kill the larvae. Seven, aphids aphids mostly occur in spring, which mainly harms young leaves and sucks juice, leading to irregular shrinkage, curling, discoloration, shedding, and even the whole plant withers and dies. At the same time, aphids secrete a lot of dense dew, which pollutes branches and leaves and induces bituminous coal disease. When a large number of aphids are found, they should be sprayed in time for control. The specific measures are as follows: ① Prepare tobacco leaves with the ratio of 1: 15, soak them for 4 hours and then spray them, or prepare pepper water with the ratio of 1:6-8 (boiling for about half an hour), or prepare washing powder water with the ratio of 1:20-30 for spraying. ② The early incubation period of aphids in spring (April and May) is the best time to control aphids. At this time, use 40% omethoate emulsion 1000 times, or 50% marathon emulsion 1000 times, or 50% chlorfenapyr emulsion 1000 times, or 50% Liu Xinlin emulsion 60 times. ③ When applying any medicine, add 0.3% soapy water or washing powder to Myzus persicae and cover it with wax powder to increase the adhesion and improve the control effect.

Edit paragraph 4. The role of camphor tree

This species is an important timber and special economic tree species in the subtropical region (southwest of China). Camphor and camphor oil can be extracted from roots, trees, branches and leaves. The main components of oil are camphor, terpenoid bicyclic hydrocarbons, camphene, limonene and eugenol. Camphor is used in medicine, plastics, explosives, antisepsis and pesticides, and camphor oil can be used as raw materials for pesticides, mineral processing, soap making, fake paint and essence. Wood is of high quality, pest-resistant, waterproof and moisture-proof, and can be used in construction, shipbuilding, furniture, cabinets, sheets, sculpture and so on. Dense branches and beautiful trees can be used as green street trees and windbreaks. The wood of camphor tree is antiseptic, insect-proof, dense and fragrant. It is a good material for making furniture and sculptures; Besides being used for extracting camphor, or being cultivated as street trees and landscape trees, camphor also has the effects of strengthening the heart, relieving fever and killing insects. If you go outdoors in summer, you can try: pick the leaves of camphor tree, crush them and apply them on the surfaces of hands and feet, which has the effect of preventing mosquitoes. Scientific research has proved that chemical substances such as terpinebicyclic hydrocarbon, camphene, limonene and eugenol emitted by camphor tree have the ability to purify toxic air, prevent cancer and filter out fresh and clean air, which makes people feel refreshed. Living in an environment with camphor trees for a long time will avoid suffering from many incurable diseases. Therefore, Cinnamomum camphora has become the first choice for landscaping in many cities and regions in the south, and is favored by the landscaping industry.

Edit paragraph 5. Camphor tree habit

Thirty years of Zhangshu

Cinnamomum camphora likes light and is slightly resistant to shade; I like warm and humid climate, and my cold tolerance is not strong. I don't have strict requirements on soil, and I am more resistant to water and humidity. But when transplanting, I should pay attention to keep the soil moisture. Waterlogged water will easily lead to root rot and death due to lack of oxygen, but I am not tolerant of drought, barren and saline-alkali soil. The taproot is developed and deep, and can resist wind. Strong germination and pruning resistance. The growth rate is moderate, and the tree shape is huge like an umbrella, which can provide shade and keep out the cold. It has a long survival period, can grow into a towering ancient tree for hundreds of years, and has a strong ability to smoke and dust, conserve water, fix soil and prevent sand, and beautify the environment. In addition, it can resist tidal wind, smoke and toxic gases, and can absorb a variety of toxic gases, which is more suitable for urban environment. Cinnamomum camphora adapts to altitude: absolute minimum temperature below 1800m:-10.00 C Illumination response: light-loving and humidity-loving response: adapts to special soil conditions: barren, salt-tolerant and air-pollution-tolerant type: hilly plain soil type: sandy loam tree species distribution: Zhejiang, Fujian, Jiangxi, Taiwan Province Province, Hubei, Hunan, Guangdong, Yunnan, Flowering period: early April to early May, yellow-green ear and fruit period:.

Edit paragraph 6. Application of camphor tree

6. 1. Landscape application

This tree species has dense branches and leaves, large crown, strong shade and magnificent posture. It can eliminate smoke and dust, keep water, fix soil and prevent sand, and beautify the environment. It is an excellent tree species for urban greening and is widely used as shade trees, street trees, shelter forests and scenic forests. Chi Pan, waterside, hillside and other places. Cluster planting, group planting, solitary planting or as a grassland background tree. Even Soong Ching Ling's former residence has two trees!

6.2 Other applications

The wood of camphor tree is antiseptic, insect-proof, dense and fragrant. It is a good material for making furniture and sculptures; Besides being used for extracting camphor, or being cultivated as street trees and landscape trees, camphor also has the effects of strengthening the heart, relieving fever and killing insects. If you go outdoors in summer, you can try: pick the leaves of camphor tree, crush them and apply them on the surfaces of hands and feet, which has the effect of preventing mosquitoes. Cinnamomum camphora can also be made into mothballs to increase fragrance. However, if you pay attention to observation, you will also find that camphor trees will also be attacked by pests and diseases. Nature is so fair that everything has its vanquisher.

Edit paragraph 7. Propagation method of camphor tree

7. 1. Seeding propagation, cutting propagation.

When the fruit is ripe, it falls by itself and the bird pecks it. Breeding with seeds should be sown with the harvest, with 7200-8000 seeds per kilogram, germination rate of 70-80% and yield per mu of 10- 15 kg. Afforestation can also sprout and renew. Pests and diseases include powdery mildew, black spot, camphor sawfly, camphor leaf roller moth, camphor moth, camphor beetle and so on.

7.2. Seedling raising techniques of Cinnamomum camphora

1. Description: Cinnamomum camphora is a good material for first-class architecture, furniture and technology with excellent material and rich fragrance. Camphor of camphor tree and camphor oil are widely used in science and technology, OEM, medicine and national defense industry. In addition, Cinnamomum camphora is an excellent tree species for greening in the "four modernizations". Cinnamomum camphora is an evergreen tree, which likes light, has strong taproots, developed roots, warm and humid climate, strong adaptability, fast growth and long life. It grows best in the floodplain with deep soil layer. Second, the breeding time 1. Mature seeds are harvested every year10-1February, then stored in sand, and can germinate and sow in early March. 2. Soil preparation. Plow and rake for the first time in early winter, and plough and rake for the second time before sowing, and apply sufficient base fertilizer. The base fertilizer is generally decomposed manure, with a per mu 1500~2000 kg or 50 kg of urea, 50 kg of phosphate fertilizer and 0/50 kg of vegetable cake. Then a high bed is built, with a general bed height of 35~50 cm and a bed width of 65438. 3. accelerate germination. In early March, camphor trees need to be germinated before sowing. Seeds can be soaked in warm water at 50℃. After cooling in warm water, soaking the seeds in 50℃ water for 3~4 times can make the seeds germinate 10~ 15 days earlier. 4. sow seeds. The row spacing of drilling is about 20 cm, and the sowing amount per mu is 10~ 15 kg. After sowing, cover the soil with straw or plastic film to keep the surface soil of the seedbed moist, which is beneficial to seed germination. 5. Tending management. After the seedlings are unearthed, the straw or plastic film should be pulled out in time, and the seedlings can be thinned when they grow a few real leaves, and the seedlings can be fixed when the height of the seedlings is about 10 cm. There are about 20,000 camphor trees per mu. After July, it is necessary to strengthen the management of fertilizer and water, and often loosen the soil and weed. Stop topdressing and irrigation in late autumn. Topdressing is usually 2~3 times, the first two times can use 7~ 10 kg urea, and the last time can use 10 kg urea and 7.5 kg phosphate fertilizer. The annual seedlings of Cinnamomum camphora/KLOC-0 can reach more than 50 cm, and the ground diameter is more than 0.7 cm. 3. The suitable transplanting time is from the middle and late March to the early April, and the transplanting density is about 0/500 plants per mu/kloc. After transplanting, it was cut off at about 10 cm above the ground. When the buds grow to about 10 cm, the main stem can be fixed, and the redundant branch buds can be cut off, leaving thicker branches. Apply 2000 kilograms of manure to the bed in winter. In this way, the DBH of 3-year-old seedlings can reach more than 3 cm.

Edit paragraph 8. Transplanting technique of camphor tree

8. 1. Seedling raising

Those who cultivate big seedlings should be transplanted, and the transplanting time should be from the middle and late March to the middle and early April, and the transplanting density is 22,500 plants /hm2.

[1] Right. After transplanting, it was cut off about 10cm from the ground. When the bud grows to about 10cm, the trunk can be fixed, and the redundant branches will be cut off, leaving the thicker branches of 1. In seedling raising, cultivation management work such as intertillage, weeding, soil cultivation, topdressing, irrigation and pest control should be carried out in time. Seedling tending shall be carried out at least 3 times in the first 1 year and 1~2 times in the second year. Cinnamomum camphora has many sprouting branches. The first three years were used to wipe off buds, mainly to wipe off 2/3 of the buds on the ground. In winter, 30 tons /hm2 manure is applied on the bed surface. In this way, the DBH of three-year-old seedlings can reach more than 3cm. When you leave the nursery, you should bring mud balls and cut off branches and leaves appropriately to improve the survival rate of afforestation.

8.2. Transplantation

Cinnamomum camphora with straight trunk, fresh bark color and vigorous tree growth transplanted in the last two years should be selected, and its new fine roots are concentrated in stumps, so the survival rate of trees is high. Try to use the seedlings in the heel as much as possible. After a few months, the roots of camphor trees in the heel begin to grow new roots, and the roots are more active, so it is easier to survive when planted in unsuitable seasons. If the seedlings of Cinnamomum camphora dug out of the nursery are planted out of season, the soil ball is bigger than normal. The bigger the soil ball, the more complete the root system and the more successful the planting. If it is a bare-rooted seedling. It is also required to be as thoughtful as possible, with long roots and more fine roots. Try to choose seedlings. Small seedlings have stronger rooting ability and higher survival rate than big seedlings. As long as they are not in a hurry to get better greening effect soon, they should be used. Planting should be timely, that is, the trimmed camphor tree seedlings should be planted immediately. If the transportation distance is far away, the root pile should be wrapped with wet grass and plastic film to keep it moist. The best planting time is before 1l in the morning or after 16 in the afternoon, but in winter, just avoid the coldest days. Planting holes shall be excavated according to general technical regulations. Base fertilizer should be applied at the bottom of the hole, and a fine soil cushion should be laid. Planting soil should be loose and fertile. Remove the topdressing of camphor tree seedlings, pay attention to planting seedlings in the planting hole (pay attention to the ornamental surface of the tree), then fill the soil and insert it, and continue to fill the top of the hole. Finally, make a cofferdam around the seedlings to stop water.

8.3.Irrigation

After planting camphor seedlings, water them immediately. For camphor tree seedlings with soil balls, stir the soil around the tree hole with iron bars or wooden sticks to fill it with water. Be careful not to damage the earth cofferdam when injecting water. The earth cofferdam should be filled with water, so that the water can slowly soak the planting holes. In order to further improve the survival rate of colonization, auxin can be added to the irrigated water to stimulate the growth of new roots. Naphthylacetic acid is usually used as auxin. Firstly, the powdered naiacetic acid was dissolved in a small amount of alcohol, and then mixed with clean water to prepare an irrigation solution with a concentration of 200 mg/kg, which was used as 1 root-fixing water for irrigation. The newly transplanted camphor tree crown has been trimmed by two thirds, the leaves have been reduced by 90%, the root system has been damaged, and the water absorption capacity is very weak, so as long as the soil is kept moist. If the soil moisture content is too large, it will greatly affect the permeability of soil, but will inhibit root respiration. If the water is accumulated for a long time, it will lead to root rot and seriously affect root growth. Therefore, attention should be paid to ventilation and drainage holes during planting. However, water thoroughly every 1 time. In the future, water carefully according to the weather and soil quality, so as to achieve the principle of "no watering, no watering, no dripping to the roots". On the other hand, to prevent water accumulation in tree holes after rain, it is necessary to check the drainage and ventilation facilities every day, and remove the blockage or water accumulation in time to ensure that the roots of trees do not accumulate water and are not dry. When the temperature drops below zero centigrade. Water spraying should be stopped at the root of soil ball. When the conditions are ripe (the maximum temperature rises above 5℃), spray water at noon every 5-7 days to moisten the leaves.

8.4. Plastic finishing

Before planting, the roots should be sorted out, and the broken roots, dead roots and rotten roots should be cut off. Chopped taproots without fine roots; The crown of the tree should also be trimmed. Generally, 1/3- 1/2 of all branches and leaves should be cut off, so that the transpiration area of the crown is greatly reduced. Seedlings with soil balls don't need root pruning, just crown pruning. When pruning. We can cut off 1/3 ~ 1/2 of the canopy with leaves, and reduce the water loss of the whole tree by greatly reducing the leaf area, but keep the basic tree shape to speed up the landscaping. Achieve greening effect as soon as possible.

8.5. Heat preservation

Low temperature weather is common from June 165438+ 10 to February of the following year. This period of time is in the golden season of afforestation and planting green trees. Because camphor tree has weak cold tolerance. It is urgent to take heat preservation measures for camphor trees. The main measures to prevent seedlings from freezing are to protect the roots of trunks, branches and soil balls. Because the transplantation of Cinnamomum camphora is generally for greening effect, which can prevent freezing without affecting the aesthetic degree of greening. The method of "three-layer antifreeze protection" can be used to protect Cinnamomum camphora, that is, three layers of foreign objects (straw rope layer 1, linen layer 2 and straw layer 3) are wrapped on the trunk and branches of Cinnamomum camphora. Another meaning of "three-layer anti-freezing protection" is to keep warm with loose mountain mud, plastic film, straw bag and so on. According to past experience, the trunk should not be insulated with plastic film. Because there are more rainy and snowy weather in winter, once water enters the plastic film, it is easy to accumulate water, which often induces the trunk to blacken and fester, and the straw has good drainage, so there is no water accumulation problem.

8.6. pest control

The leaf roller moth occurs for several generations in 1 year, the larvae feed on young branches and the injured seedlings die. Larvae can be sprayed with 40% dimethoate solution 200-300 times, and when larvae pupate in large quantities, it can be combined with weeding and soil cultivation to kill insect pupae. Anoplophora longissima mainly harms the main branches and lateral branches, and it is killed manually or injected with dichlorvos through drainage holes. Cinnamomum camphora larvae feed on the tender branches of Cinnamomum camphora leaves, which seriously affects the growth of Cinnamomum camphora. The insect occurs in Henan Province 1 year 1 ~ 2 generations, and the early May and early June are 1 and the second generation larval stage respectively. 90% trichlorfon or 50% marathon emulsion can be sprayed 2000 times. You can also use 0.5 kg of Flos rhododendri mollis or tripterygium wilfordii powder mixed with 75- 100 kg of water to make a liquid medicine for spray insecticide. Moth larvae gather in groups on the new shoots to feed on leaf buds, and spin silk to roll the leaves into balls and wrap the terminal buds, resulting in the death of the new shoots. This larva has two generations in 1 year, and the larvae of 1 generation are harmful from the end of May to the middle of July. When the second generation larvae have not formed a net nest, 90% crystal trichlorfon is sprayed 4000 ~ 5000 times. If the larvae have formed a net nest, they can be manually removed and burned.

Control method: 40% dimethoate solution can be sprayed 200-300 times to kill locusts, and when locusts pupate in large quantities, weeding and soil cultivation can be combined to kill locust pupae. 2. camphor tree. Zhejiang Province has 1 or 2 generations a year. Early May and early June are the first and second larval stages, respectively. Prevention and control methods of larval damage to young leaves: spray with 2000 times solution of 90% crystal trichlorfon or 50% marathon emulsion, or spray with 0.5 kg of Flos rhododendri mollis or 75- 100 kg of water of tripterygium wilfordii powder. 3. Moth moth. Larvae gather on the new shoots and feed on the leaf buds. Spinning rolls the leaves into a ball and wraps the terminal buds, resulting in the death of the new shoots or even the whole plant. Prevention and control methods: This larva has two generations a year, and the first generation larva is harmful from the end of May to the middle of July. When the second generation larvae have not formed a net nest, they should be sprayed with 90% crystal trichlorfon 4000-5000 times. If the larvae have formed a net nest, they can be manually removed and burned. 4. powdery mildew. At first, grayish brown spots appeared near the main veins on the back of young leaves of seedlings, and then spread to the whole back of leaves, and a layer of white powder appeared. Prevention and control methods: pay attention to the hygiene of nursery, properly sparse seedlings, and immediately pull out and burn the diseased plants when they are found. When the symptoms are obvious, spray with lime-sulfur mixture with Baume degree of 0.3-0.5 every 65,438+00 days for 3-4 times in a row.
