Excuse me, does anyone know that there is a medicinal material called Dendrobium candidum in Sichuan?
Does anyone know the function of Dendrobium candidum? Dendrobium candidum has the function of nourishing yin and enriching blood. It is rich in polysaccharide and has the function of enhancing immune function. Modern pharmacological research also shows that Dendrobium candidum can improve stress ability and has good anti-fatigue and anti-hypoxia effects. I bought Dendrobium for Xu Xiaoyun before, and my family felt very good after eating it. Please refer to the topic.
Do you sell Dendrobium candidum in Sichuan? Dendrobium candidum is not produced in Sichuan, but there seems to be a company called Tongfenghu in Panzhihua. They have their own Dendrobium candidum base and many products. If you want to buy it, you should be able to express it.
Dendrobium candidum is planted in Sichuan, but not in Neijiang. I'm doing it.
Where can I buy Dendrobium candidum? There are usually some large Chinese medicine shops.
There are also online, but also for sale.
This health care effect is still very good, which has been mentioned in many programs on TV.
Excuse me, where is Dendrobium candidum planted in Sichuan? There seems to be one in Chengdu, Sichuan, in Jintang Dongfeng Reservoir. Go and see for yourself.
Is Dendrobium candidum planted in Sichuan? Dendrobium is mainly planted in Zhejiang and Yunnan. Sichuan has almost never heard of it, and it comes from the world of Chinese herbal medicines.
Does anyone know which mask contains Dendrobium candidum ingredients? There is Dendrobium candidum in Yixian muscle. Dendrobium candidum is the hand of China's Nine Immortals. Rich in Dendrobium polysaccharide, Dendrobium alkaloids and trace elements. Beauty beauty has the functions of promoting fluid production, nourishing stomach, expelling toxin and caring skin. I hope it helps you.
Are there any Dendrobium officinale plants? What are the planting techniques of Dendrobium candidum? The planting techniques of Dendrobium can be divided into four aspects: attachment, reproduction, field management and pest control. Dendrobium likes a cool and humid environment and often adheres to cool and humid trees and rocks.
In the world, especially in semi-cloudy and semi-sunny places, limestone and mossy trees grow best. Hejiang County, Sichuan Province is the main producing area of Dendrobium, with an altitude of about 280 meters and an average temperature of 18.2℃, which is the highest on average.
The temperature is 2 1.9℃, the average minimum temperature is 15.3℃, the extreme maximum temperature is 40.7℃, the extreme minimum temperature is-1.2℃, and the annual precipitation is 1 184 mm, which is more suitable for the growth of Dendrobium.
First, the preparation of Dendrobium candidum before transplanting
1. Select seedlings
Bottle seedlings grow well, with normal leaf color, root length of more than 3cm, fleshy stems with 3-4 internodes and 4-5 leaves, normal leaf color, root length of more than 3cm, 4-5 roots, white-green root skin, no black roots, no deformity and no variation.
Get out of the bottle
group
When the cultivated seedlings are taken out of the bottle, the culture medium and seedlings are gently taken out, neatly placed in the basin to be cleaned, and the contaminated seedlings, bare-rooted seedlings or few seedlings are placed separately. Normal tissue culture seedlings were washed with clear water, especially agar, to
Avoid root rot caused by mildew of agar, and then clean it with clear water. After the above cleaning, the bare roots or the roots of a few tissue culture seedlings should be soaked in 100mg/L ABT rooting powder 15 minutes to induce rooting.
Tour guide. After cleaning the contaminated seedlings, soak the whole seedlings in carbendazim 1000 times solution 10 minute. Proper management in the later stage can effectively control the occurrence of pollution.
3. Preparation of matrix
Suitable substrates should be selected for transplanting tissue culture seedlings of Dendrobium candidum. The roots of Dendrobium candidum are aerial roots, with obvious aerobic and shallow roots. Therefore, it is advisable to require the substrate to be loose and breathable, well drained, not easy to be moldy, free from germs and hidden pests. Weeds, limestone, broken bricks, bark, shavings, fern roots, board edges, fungus chaff and wood chaff can be selected as transplanting substrates.
4. Selection of cultivation sites
iron
Dendrobium candidum likes warm, foggy, breezy, clean and scattered environment, avoiding direct sunlight and exposure. In the process of transplanting, conditions should be created to create the best growth environment for Dendrobium candidum. The origin of Dendrobium candidum is mostly in temperate zone and sub-temperate zone.
Tropical, the climate is warm and humid all year round, and the temperature in winter is above 0℃. According to the growth habit of Dendrobium candidum, natural factors such as light, temperature, humidity and ventilation should be considered. I think it's best to move in the greenhouse.
If you plant it, you have to transplant it on the elevated side, so it is easy to meet the best environmental requirements for the growth of Dendrobium candidum, and many natural factors are easy to control. The construction of seedling greenhouse should meet the following three conditions:
(1) The seedling greenhouse needs electricity, water and access. The greenhouse is required to have a width of 6m, a length of 30m, a shoulder height of more than 107m, a roof height of more than 2.8m, and a plastic drip-free film and a sunshade net with a shading degree of 70%.
Tap water pipes are installed inside, and 40-mesh insect-proof nets are installed around and at the entrance of the greenhouse. If conditions permit, the shed should also be equipped with an automatic or manual control spraying system (preferably spraying drugs and spraying fertilizers and drugs), so as to prevent it.
Sun protection, rain protection, insect prevention, heat preservation, moisture prevention, ventilation, and greatly reduced labor.
(2) An elevated planting bed is set in the shed, and the bottom of the bed is overhead. Angle steel, bricks, wooden strips or square strips can be used as planting materials.
The frame of the frame, and then a plastic flat plate with an aperture of 0.3-30~50cm is laid as the supporting surface of the cultivation substrate, and the width of the frame is required to be 1~ 1.2m, the length of the frame can be determined by itself, and the overhead height at the bottom of the frame is 30-50 cm. Planting bed
There is a nozzle on it, which can be sprayed at any time. It is best to control the spraying time. If there are no conditions, you can also use a sprayer instead. The purpose of setting an elevated planting bed is to make the water permeability and air permeability easy to control, so as to facilitate tissue culture and seedling raising.
It can provide the best moisture, ensure ventilation, and spray fertilizer and medicine at the same time, which has a high survival rate of transplanting and can greatly save labor when transplanting in a large area.
(3) spreading a layer of substrate with a thickness of 5-8 cm on the planting bed, and paving. Before transplanting, the substrate was sprayed with 0.3% potassium permanganate or 1000 times carbendazim solution for disinfection.
Second, Dendrobium candidum transplantation
1. transplant time
The best transplanting season should be when the daily average temperature is 15~30℃, and the temperature is too low or too high to be transplanted out of the bottle.
2. Transplantation method
Carefully take out the tissue culture seedlings with tweezers, wash off the culture medium, and then transplant them to the planting bed. When transplanting, dig a hole 2~3cm deep in the substrate with your fingers, gently put the roots of Dendrobium into the hole, be careful not to break the fleshy roots of Dendrobium, and then cover them with the substrate. Bare-rooted seedlings or few-rooted seedlings are best planted separately for easy management.
Third, the management of Dendrobium candidum after transplantation
1. Temperature management
Artificial transplantation of tissue culture seedlings of Dendrobium candidum should meet the requirements of warm in winter and cool in summer. The suitable temperature for the growth of tissue culture seedlings is 20~30℃. When the temperature is high in summer, the greenhouse should be ventilated and cooled, and it should be sprayed frequently to cool down and moisturize, 3~5 times a day for 2~5 minutes each time; When the temperature is low in winter, the greenhouse should be sealed around to prevent tissue culture seedlings from frostbite.
2. Humidity management
only
Transplanted tissue culture seedlings are sensitive to water, but lack of water leads to slow growth, dryness and low survival rate. However, excessive spraying will lead to waterlogging and root rot, which is easy to cause large-scale soft rot in the case of high temperature and high humidity. Within a week after transplantation (the seedlings have not yet
The air humidity should be kept at about 90%. After a week, plants begin to grow new roots, and the air humidity can be kept at 70%~80%. The cross potential of planting border between dry and wet is beneficial to rooting and germination.
3. Fertilizer and water management
big
Foliage fertilizer is the main fertilizer for transplanting in greenhouse. Because Dendrobium is aerial rooting, it is necessary to spray suitable foliar fertilizer as nutrient solution to provide sufficient nutrients for plants, which is conducive to early rooting and long buds. Potassium nitrate and phosphoric acid can be selected as foliar fertilizers.
Potassium dihydrogen, humic acid, etc. , as well as imported ternary compound fertilizer and diluted MS medium. Generally, one week after transplanting, one thousandth of potassium nitrate or potassium dihydrogen phosphate is sprayed after new roots appear, and once every 7~ 10 days.
Three times, three times in a row. Spraying 3‰ ternary compound fertilizer every 10- 15 days after new buds grow. In general, watering is stopped two days after fertilization. If the air convection is too large, water should be sprayed appropriately according to the dry humidity of the substrate.
Four, Dendrobium candidum cultivation techniques
1. Land selection and preparation
root
According to its growth habit, the cultivation place of Dendrobium candidum should be selected in semi-cloudy and semi-sunny environment, with air humidity above 80% and winter temperature above 0℃, or in artificially controlled environment. The suitable tree species are Liriodendron, pear and camphor trees. So it should be.
Live trees with thick bark, longitudinal grooves, high water content, flourishing branches and thick trunks should also be in cool and humid places, with moss growing on the stones and a small amount of humus on the surface.
2. Breeding method
can
So as to propagate seedlings through tissue culture or ramet propagation. Dendrobium planting is generally carried out in spring, and it is easy to survive because of the high humidity and increased rainfall in spring. Select robust Dendrobium without diseases and insect pests, and cut off the old Dendrobium which has been more than 3 years.
Stems are used for medicine, and biennial new stems are used for reproduction. When breeding, the old roots are subtracted, leaving 2-3 cm, seeds are separated, each plant contains 2-3 stems, and then cultivated in a greenhouse with decomposed soil on the mountain.
3. Tian Tuan management
(1) Watering-When the air humidity is too low in the late stage of Dendrobium planting, water it frequently to keep it moist, and spray it with a sprayer.
(2) Topdressing-Dendrobium should pay attention to topdressing during the growing season. The mixture of rotten peanut drum, rapeseed cake and calcium superphosphate can be added to the roots. In addition, 0.05-0. 1% potassium dihydrogen phosphate can be used for topdressing outside the roots.
(3) Pruning: before the new buds germinate every spring, the dead stems in the cluster are cut off in combination with the old stems, and the diseased stems, weak stems and diseased roots are removed. After planting for 6-8 years, according to the growth of the clumps, turn them over and re-branch and reproduce.
Dendrobium has strict requirements on the growth environment. Wild Dendrobium grows in the crevices of cliffs, trunks, branches or rocks, and is nourished by clouds, dew, rain and fog all the year round. The natural shading degree is generally 70%-80%. In the wild, cassiterite
Dendrobium mainly grows in tropical and subtropical virgin forests and similar warm and humid environments, and mainly epiphytes on the trunks of some broad-leaved trees in the forest. Growth conditions require "warmth", "humidity", "ventilation" and "ventilation"
Gas "and" water leakage ". There are strict requirements on the temperature and humidity of the growing environment. At present, there are only a handful of living environments for wild Dendrobium in the world. Most people in the market call themselves Firefox or Firefox.
It's called iron maple bucket. There are only two places where you can buy authentic peace of mind, one is Tongrentang and the other is Dendrobium candidum in Fulinmen, which is more affordable.
4. Harvest and processing
(1) harvesting-harvesting before germination in late spring every year. When harvesting, cut off the stems and branches that are more than three years old, leaving the tender stems to continue to grow.
(2) Processing-There are two methods according to varieties and commercial medicinal materials:
(1) Wash the collected stem plants, remove the leaves and fibrous roots, separate single stem plants, scald them with hot water at 85℃ for 1-2 minutes, pick them up, spread them on bamboo mats or concrete floors, expose them to the sun until they are 50% dry, rub them off by hand, and then spread them in the sun, paying attention to turning them frequently until they are dry.
(2) You can also soak the washed Dendrobium in boiling water for 5 minutes, take it out to dry, put it on a bamboo mat, turn it over 2-3 times a day, dry it while rubbing it until it becomes soft, and repeat it many times until the residual leaf sheath is removed, and then dry it until the feet are dry.
Where can I buy Dendrobium candidum seedlings? General pharmacies have it, but the cost performance is not high. You can go to the flower and bird market, which is cheap. I have one, too.
