What methods are there to promote the rooting of flowers?
2. Treating cuttings with potassium permanganate solution. Immerse the cutting base in 0. 1-0.5% potassium permanganate solution for 2 cm, take it out after 12-24 hours, and cut it immediately.
4. girdle. In the process of flower growth, the base of branches is annularly peeled off, which makes the girdling part accumulate a lot of nutrients, and cutting along the girdling part can promote rooting during dormancy.
What flowers like acidic soil? What flowers like acidic soil?
Beautiful flowers enrich life. Do you know that different kinds of flowers grow in different environments? In fact, flowers have requirements not only for temperature and humidity, but also for soil. So do you know which flowers like acidic soil? What are the flowers that like acidic soil? Many flowers like acidic soil. Here are some flowers that like acidic soil for your reference.
1, gardenia
Gardenia likes to grow in acidic soil, which can provide the nutrition for gardenia. Gardenia usually blooms in July, and the color of flowers is mainly white. When gardenia is in full bloom, it gives off a faint fragrance, and smelling the fragrance of gardenia makes people full of energy. Gardenia has a pleasant fragrance, which can make the room full of fragrance when placed indoors.
2. cherry blossoms
Cherry blossom is a flower suitable for growing in acidic soil. They are very beautiful in clusters, mostly pink and white in color. The pink cherry blossoms that people can't put down add a lot of romantic colors and unique beauty to the world.
3. Jin Chahua
Jin Chahua, belonging to Theaceae, is a national first-class protected plant. Jin Chahua is called Jin Chahua because most of its flowers are golden yellow and bright, and the surface of the flowers is as smooth as a layer of wax. If Jin Chahua lived in acidic soil, it would grow better. Moreover, diluted yogurt can also be used as fertilizer.
4. Begonia
Begonia belongs to Rosaceae and is an ornamental flower with a long history. Its flowers are colorful and dazzling. In ancient times, many scholars wrote poems and paintings on the theme of begonia. Begonia is suitable for growing in acidic soil, and it can absorb nutrients from acidic soil, so that it can bloom better.
5. Chlorophytum
Chlorophytum is a perennial herb with slender and drooping branches. When the temperature is high in summer or other seasons, small white flowers are blooming, and the flowers are concentrated at both ends of the drooping branches. Stamens are yellow, and the leaflets inside are sometimes purple, which can be used for potted viewing. Chlorophytum has strong adaptability to various soils and is easy to cultivate. It is best to use fertile slightly acidic soil, sandy loam soil, humus soil, peat soil, or fine sandy soil with a small amount of base fertilizer as potted soil.
There are ways to change pots and flowers.
Changing the pot is also called turning the pot. With the growth of flowers and plants, the small pots are gradually covered with roots, so it is necessary to replace them with larger flowerpots and add some culture soil to make the flowers get enough nutrients. It's called changing pots. Herbaceous flowers, biennial, need to change pots once or twice before flowering. Perennial flowers change pots every year 1 time; Woody flowers can change pots every 1 year. The purpose of changing pots is to improve the nutritional status of plants. For example, Milan, Rose, Jasmine, Poinsettia and Fusang need to turn pots 1 time every year, while Camellia, Orchid and Rhododendron grow slowly, but turn pots 1 time every other year.
For large-scale perennial potted flowers, due to the gradual development of roots and long-term watering, the soil in the pot will gradually decrease, the soil will become hard, the air permeability will gradually be worse than before, and the nutrients in the soil will gradually be insufficient.
Therefore, even if the big potted flower still uses the original pot, it is necessary to change the soil 1 time within at least two years, trim off some rotten roots, too long roots, rotten roots and roots invaded by pests and diseases, and add some new soil to help the plant continue to grow. It is best to change pots during the dormant period of flowers. Generally, woody and perennial flowers can be changed in March and turned over after flowering in early spring.
When turning the pot, first pry the pot soil around the pot wall with a knife, turn the pot over with one hand, then pat the pot wall to remove plants, and hold the plants with soil with the other hand. Then cut off some old soil outside the root system with a knife, cut off some bad roots and some old roots, replant them in pots, add new soil outside the soil balls for compaction, and then water them. The planting depth of flower seedlings remains the original state. Perennial flowers can be divided into plants while changing pots.
When changing large pots, in order to drain well, reduce weight and facilitate movement, a layer of furnace ash residue can be laid on the bottom of the pot, followed by a layer of soil, and some fish scales and broken bones can be added as base fertilizer to maintain long-term fertility.
Family hydroponic flower cultivation method
1. What are the difficulties of hydroponic flowers in summer? Hydroponics is the cultivation of ornamental plants with non-solid medium (water or water containing appropriate plant nutrient solution). At present, most family hydroponic flowers are cultured in still water, and the dissolved oxygen is lower than 1mg/l, so the flowers barely maintain their lives in anoxic containers. With the temperature rising in summer, the physiological metabolism of plants is vigorous, microorganisms multiply, the oxygen consumption increases sharply, the dissolved oxygen decreases continuously, and the water quality deteriorates, which may cause many unfavorable factors to the growth of hydroponic flowers, resulting in root rot, withered branches and leaves, and even premature death of plants and flowers. Therefore, in summer, in addition to preventing extreme heat and high temperature, improving the oxygen content of nutrient solution is the key to ensure the safety of hydroponic flowers in summer.
Second, how to improve the content of dissolved oxygen in nutrient solution?
There are many ways to increase dissolved oxygen, which can be summarized as chemical methods and physical methods. Here are some simple and effective methods.
1. Increasing the number of nutrient solution changes is the easiest way to increase dissolved oxygen. It is determined that the dissolved oxygen content of fresh nutrient solution is 70%-90% higher than that of the original solution, which can improve the physiological hypoxia of flowers in time. For flowers that have been rooted for 3-5 days, it is advisable to change the nutrient solution once every 7 days at most. When replacing nutrient solution, pay attention to the temperature difference between the new solution and the original solution, which may cause physiological disorder of flower root system. When changing the liquid, wash the root system patiently with clear water, remove dead roots and rotten roots, cut the old roots short and grow new ones. If the nutrient solution suddenly becomes turbid or there are mosquito eggs, it should be replaced with a new nutrient solution immediately.
2. As long as the root system is clear and intact and the nutrient solution is thorough, hydroponic flowers can be oxygenated by vibration. The operation method is to hold the flowers in one hand and shake the vessel 10 times with the other hand, and the dissolved oxygen content of the nutrient solution after shaking can be increased by more than 30%. For hydroponic flowers with turbid nutrient solution and poor root system development, it is not appropriate to adopt the method of vibration oxygenation, and all nutrient solutions must be replaced.
3. Inflate the container. If there is a tank of ornamental fish next to the hydroponic flowers, you can use the oxygen rod of the fish tank to inflate the container.
3. Where should the hydroponic flowers be placed in summer?
The flowers used in hydroponics are mostly shade-tolerant flowers and flowers with both leaves and leaves. If taro, white jade evergreen, silver bud taro, candle, pineapple, etc. These flowers are warm, slightly shade-tolerant, and avoid high temperature and dry heat. Hydroponics only changes the cultivation form, and it is impossible to change its growth habits, which requires environmental factors. In summer, it is best to place hydroponic flowers in a bright, slightly higher humidity, cooler and well-ventilated environment. Avoid direct sunlight, but don't be too cool, so as not to hinder the photosynthesis of flowers, weaken their growth, make the stems longer and the leaves thinner. The flower leaves with colored blocks and patterns have lost their luster.
4. Can hydroponic flowers be put in an air-conditioned room?
Of course. However, hydroponic flowers should not be placed directly at the air outlet of air conditioning. If the wind speed is too fast, the branches and leaves will be hurt, and the leaves will curl or wither. It should also be taken into account that the temperature of flowers is required to be higher during the day than at night. If the air conditioner is turned off at night, the ambient temperature is higher than the daytime temperature when the air conditioner is turned on, which is unfavorable for the growth of hydroponic flowers. When the air conditioner is turned on, put a pot of water next to the flowers or spray it on the leaves to increase the humidity of the environment. The flowers are placed far away from the air outlet of the air conditioner, so there is no problem that the temperature difference between day and night is not big.
5. What about hydroponic flowers and rotten roots?
With the continuous increase of temperature, the water temperature will also increase, microbial reproduction will accelerate, dissolved oxygen will decrease, and water quality will become worse. Improper addition of nutrient solution and high dissolution concentration may cause root rot of hydroponic flowers, especially pig's feet, horsetail (Millennium chrysanthemum) and five-color Millennium chrysanthemum of Liliaceae. The following methods can be used to restore the growth of flowers with rotten roots: a. Remove all rotten roots, and if the stems have been infected, cut off the infected parts with a sharp knife. B. Soak the trimmed flowers in 0.5% potassium permanganate solution 10-20min for sterilization. C, taking out the soaked flowers and washing them in running water. D put the washed flowers into the original vessel and plant them with clear water (the vessel should be cleaned). E, change the water once every 1-2 days, and only change the fresh water without changing the nutrient solution. The water quality is clear, which can reduce the number of water changes. After 10- 15 days of maintenance, new roots can sprout. F, the newly sprouted new roots are still cultivated with clear water, and when the temperature is stable at 18-25 degrees, they are cultivated with nutrient solution.
6. What should I do if the nutrient solution breeds algae?
Algae propagation in nutrient solution is a common phenomenon in the process of hydroponic flower cultivation. Especially in summer, the temperature is high, the transparency of utensils is good, and the environment is bright. Or it takes too long to replace the nutrient solution, which will lead to a large number of algae. Algae flowers carry oxygen, and secretions pollute the solution, which reduces the quality of nutrient solution. Algae attached to the roots of flowers hinder the respiration of roots and interfere with the normal physiological activities of flowers, which is extremely harmful. Once the nutrient solution breeds algae, decisively dump the contaminated solution, thoroughly clean the utensils, brush off the algae attached to the flower roots and replace it with a new nutrient solution.
7. What fertilizer is used for hydroponic flowers? How to fertilize in summer?
Hydroponics is a special cultivation form, which belongs to soilless culture. The roots of flowers are anchored in water (or special plant nutrient solution), which is also called nutrient solution cultivation.
Hydroponic flowers should be cultivated with plant nutrient solution. However, different flowers need different nutrients at different growth stages. If five bottles, six bottles or even a dozen bottles of different varieties of hydroponic flowers are planted at the same time, it is unrealistic to buy a bottle of plant nutrient solution for each flower. Simply put, you can choose to use general plant nutrient solution.
Generally, plant nutrient solution generally contains all nutrient elements (including macro elements and trace elements) necessary for flower growth. The proportion of each element is balanced, the inorganic salt is ionic, the application range is wide, it is suitable for the needs of different flower varieties in the growth period, and it is non-toxic and harmless, and its pH value and ion concentration are beneficial to nutrient absorption. There are many kinds of plant nutrient solutions sold in the market. It is best to go to hydroponic flower shop to buy products with good reputation from manufacturers.
There are different opinions on whether to cultivate with nutrient solution or only with clear water in summer. According to the author's experience, flowers with high temperature resistance and vigorous growth should be cultivated with nutrient solution; Flowers with slender roots, semi-dormancy and dormancy at 30℃ are cultivated only with clear water. Such as silver-bracted taro, green radish, small turtle back bamboo, ruby, taro and so on. It is suitable to cultivate with nutrient solution to maintain the growth advantage and improve the ornamental grade. Flowers such as colored grass, bamboo begonia and pineapple can spend the summer safely with a bottle of clear water.
The proportion of nutrient solution should strictly follow the instructions, and the concentration should not be increased at will. Because the root tissue structure of flowers germinated by hydroponics has changed, it is looser and larger than that of soil culture. The cell wall becomes thinner and absorbs water, nutrients and oxygen directly from the nutrient solution, which is extremely sensitive to the concentration of the nutrient solution. Too high a concentration is harmful to flowers. As long as the concentration of major elements is not lower than 1 liter, the lower concentration is beneficial to the growth of flowers. It is advisable to change the nutrient solution every five days in summer.
Eight, can you change the flowers planted in the soil into hydroponic flowers in summer?
It is most suitable to change soil-cultured flowers into hydroponic flowers in spring and autumn, when the temperature is around 15 ~ 25℃, which is suitable for flower growth and easy to adapt to the changing cultivation environment. The following factors should be considered to change the cultivation form of summer flowers: ① Choose the quality close to the relationship between wet flowers. ② Flowers that still grow normally and develop well when the temperature is around 30℃. The experiment proved that the survival rate of Araceae taro, tortoise plastron, ruby taro, Hulk, green radish and some bromeliad flowers increased after changing from soil culture to hydroponics in summer. They quickly adapted to hydroponics, and their roots rarely rotted. After 15 ~ 20 days of culture, not only lateral roots grow on the old roots, but also rhizome tips can germinate and take root. When changing from soil culture to hydroponics, the soil in the flower rhizosphere should be removed. Rinse repeatedly to protect the root system from damage or less damage, take a large-capacity vessel for cultivation, change the water once a day, and change the water once every 2-3 days after five days until the water roots grow to 5 cm long, and cultivate with low-concentration plant nutrient solution.
