How to promote the rooting of plants?

Question 1: Is there any way to make plants take root more easily, make the soil at the roots of plants softer and have the right humidity? If you want to cut plants, it is better to soak the lower head of the cutting plants with vitamin B 12, and then cut them after drying. After cutting, the cutting seedlings should not be exposed to the sun directly, but should be placed in a cool and ventilated place, so that the cutting seedlings will not die because of excessive water loss. But with more water loss, you can give full play to the nutrients in the cutting stems and give birth to roots.

Question 2: How to promote the rooting of aquatic plants is an important form of soilless culture of flowers. Hydroponics is a kind of nutrient solution cultivation without substrate, which is cleaner and more environmentally friendly than ordinary soilless flowers, with elegant style and strong ornamental value. However, hydroponics with substrate, especially deep liquid water culture, has low oxygen content, which often fails to meet the needs of crop roots, leading to root rot and poor growth. In order to solve this problem, horticultural scientists all over the world have taken many measures, such as applying closed-loop flow of nutrient solution to oxygenate water. Although these technical measures have certain effects, it is still quite difficult to realize the stable production of irregular hydroponic multi-variety flowers. At present, only a few flower varieties in the world, such as hyacinthus orientalis and Tulip, have achieved commercial hydroponics. The researchers of Northeastern University in China adopt interdisciplinary science and technology, comprehensively apply plant physiology, plant nutrition and mechatronics technology, and learn from the successful experience of soilless culture technology at home and abroad. After eight years of research, they finally succeeded in developing the factory soilless asexual propagation method of flowers, which solved the problem of flowers from soil culture induction to hydroponics. In June, 2003, 165438+ 10, this technology was officially granted the invention patent by China National Intellectual Property Administration. At present, this patented technology of factory hydroponic flowers has been implemented in Shenzhen and other places. Using this technology, more than 500 varieties of hydroponic flowers in 9 series have been successfully cultivated, including 32 species of pineapple, 5 species of flamingo, 5 species of Orchidaceae, 8 species of fern ornamental plants 10, 8 species of arrowroot, 290 species of foliage plants, 52 species of cactus and succulent flowers, strawberries and raspberries.

Technical points

The patented technology of factory hydroponics flower cultivation is based on deep liquid flowing water cultivation technology, and has made important improvements in nutrient solution preparation, oxygenation scheme, water disinfection treatment and so on.

Formula of nutrient solution Regarding the formula of nutrient solution, Table 1 gives the formula of six common nutrient solutions for hydroponic flowers, such as leaves, flowers, fruits, flamingos, orchids and ferns, with comprehensive nutrition, reasonable proportion and strong pertinence. The formula not only contains a large number of elements of nitrogen, phosphorus and potassium, a mixture of medium elements of calcium, magnesium and iron, and trace elements of manganese, zinc, boron, copper and molybdenum, but also contains a hydroponic rooting inducer and an aquatic inducer. Hydroponic rooting inducer is a new growth regulator to promote plant rooting under hydroponic conditions. Aquatic inducer is a regulator containing adenosine triphosphate, which guides plants to adapt to hydroponic environment. It can promote the movement of inorganic ions in nutrient solution against electrochemical potential gradient, that is, it can increase the active absorption and transfer of nutrients by plants. Although the dosage of these two regulators is not large, they do play an important role in ensuring the normal growth and development of hydroponic flowers, especially in the early stage, which can significantly improve the survival rate of hydroponic plants.

Oxygen-increasing technology In order to solve the problem of low oxygen content in deep-water aquaculture, researchers chose the oxygen-increasing technology combining magnetic physical oxygen-increasing, chemical oxygen-increasing and mechanical oxygen-increasing (see the national invention patent "A method for manufacturing oxygen-enriched drinking water", patent number 001kloc-0/0622.8), so that the oxygen content in water can be 5 ~10 as needed.

Water temperature control About the temperature of greenhouse, for hydroponics, we should not only control the temperature of greenhouse, but also pay attention to the control of water temperature, that is, the temperature of nutrient solution (see Table 2). Controlling the temperature within the physiological temperature range of plant roots can promote the effective absorption of various nutrients by hydroponic flowers, thus promoting the physiological metabolism and growth and development of plants. In order to control the water temperature, nutrient solution culture tanks are generally built at about 100~200mm below the ground. In summer, combined with the fan and water curtain cooling system in the greenhouse, when the outdoor temperature is 35℃, the indoor temperature can generally be reduced to below 30℃, while the water temperature in the culture pond is about 23℃~27℃, so that plants can spend yesterday's summer safely. In winter, the underground pool can make the water temperature 3℃~5℃ higher than the greenhouse temperature, reducing energy consumption and temperature fluctuation. For the northern greenhouse heating in winter, it is also a feasible scheme to heat the hydroponic pond through pipes, which can reduce energy consumption and temperature fluctuation, which is particularly important for the production of hydroponic New Year's Eve flowers.

Leakage of water and fertilizer Because hydroponic flowers are cultivated in an impermeable culture pool, there is no leakage of water and fertilizer, which is an efficient cultivation method of saving water and fertilizer. The nutrient solution should be supplemented and adjusted according to the consumption every week, so that the nutrient solution in each pool can be used continuously for 2-3 seasons. According to the calculation, the proportion of hydroponics is ... >; & gt

Question 3: What can promote plants to take root and grow leaves? There are many elements and trace elements, which are generally divided into nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer. Nitrogen fertilizer mainly promotes leaf growth and organic matter synthesis. Phosphorus is mainly the division and inheritance of cells, as well as rooting and growing leaves. Potassium contributes to the transport of nutrients and promotes rooting and leaf growth. There are also medium and trace elements, and nothing is enough. In this way, according to the amount absorbed, it is mainly nitrogen, phosphorus and potassium.

Question 4: What medicine can promote the rooting of plants? Rooting powder, α-naphthylacetic acid.

Question 5: How to promote the rooting of hydroponic plants If the temperature is too low, the rooting of plants will be slower. This is because the activity of the enzyme is inhibited.

You can add a little rooting powder to the water properly.

Question 6: How to make plants take root and sprout and come back to life quickly? If it is a transplanted plant, it is best to water it with warm water in winter to keep the soil moist. If it is a cuttage plant, you can consider buying "rooting powder" in the shop selling horticultural plants to promote the rooting of plants.

Question 7: What can promote the rooting of plants ABT rooting powder? Flowers are usually sold there. Soaking in 0. 1% ~ 1% potassium permanganate solution for 24 hours and 2% ~ 10% sucrose solution for 24 hours can also take root quickly.

Question 8: How to make plants take root quickly? 1.3 Change the water once a day, and use dried tap water.

2. Add a small amount of root accelerant.

3. The container is protected from light and promotes hair roots.

Question 9: What can promote the rooting of plants ABT rooting powder? Flowers are usually sold there. Soaking in 0. 1% ~ 1% potassium permanganate solution for 24 hours and 2% ~ 10% sucrose solution for 24 hours can also take root quickly.

Question 10: How to make hydroponic plants take root quickly? A good way to take root in hydroponics is that ivy is a beautiful ivy flower. Leaves are broadly triangular, ovate, alternate and leathery. Old leaves are dark green, dotted with gray-white spots, slightly white veins, and irregular dark yellow and white leaves; The new leaves are bright, dotted with pale yellow-gray spots, with white veins and yellow-white leaves; The newborn leaflets are spoon-shaped, bright green, with bright white veins and pale purple spots dotted with yellow-white leaves. Its vines either climb on rockeries and scaffolding or crawl on the ground. In autumn, yellow flowers are full of branches, and the inflorescences are spherical and umbrella-shaped. Black cones are decorated on vines, which are in harmony with the leaves. They are elegant, unique and interesting. Ivy belongs to Araliaceae and originated in Europe. Sex likes sunshine, but it is resistant to shade and cold, and does not choose soil. Simple management, timely and appropriate application of some nitrogen, phosphorus and potassium fertilizer to make its vines strong and leafy. Cut off dead branches and leaves in time to keep their graceful posture. The propagation method is sowing or cutting. Sowing humus soil, garden soil and river sand are mixed according to the ratio of 3: 2: 2, and the fine ones are screened and disinfected before use, or the disinfected fine river sand is used. After sowing, cover with soil about twice the diameter of the seeds, and cover with plastic film or glass, and keep the temperature at 20℃-25℃ and keep it moist. Remove the plastic film or glass sheet after budding. Three leaves can be transplanted. 65438+ 10 May to June, the tender branches or old branches of the current year were cut into the sterilized Xihe sand, kept moist, covered with plastic film, the temperature was controlled at 20-26℃, and the air relative humidity was 80-90%, and took root in about 20 days. The survival rate is above 90%.

You can't change the water every day, which is easy to rot. Just change it every 3-5 days to let it bask in the sun, but you can't change the water directly. Putting a copper coin in water can improve the quality of water and make it grow better. Spray bamboo leaves with a watering can. Don't let them dry, so the leaves won't turn yellow and dry. You need to replenish some nutrient solution when they take root.

Or you can buy some rooting powder.

Rooting powder can accelerate the formation of adventitious roots, shorten rooting time, promote root development and improve rooting rate and survival rate. It is especially suitable for cutting flowers, transplanting and transplanting, and has a certain effect of increasing production and income. It can promote the formation of new roots, accelerate rejuvenation, increase chlorophyll content and improve survival rate.
