Brassinolide is a broad-spectrum and highly effective plant growth regulator. It is different from other plant growth regulators in promoting crop yield and improving quality, which is unidirectional and targeted.
Brassinolide is suitable for all crops and can be used throughout the growth period. It can promote cell division, enhance photosynthesis, improve crop resistance to disease, drought, salt and alkali, waterlogging, cold and other stress resistance, assist the good growth of the disadvantaged part of the crop, and has a significant effect on increasing crop yield and income, and can also alleviate the damage caused by pesticides and restore growth.
The main functions on fruit trees are:
① Promote shoots: It can promote shoots and mature in advance.
② Promote flower bud differentiation and bloom more strong flowers.
③ Protect flowers and fruits: Stimulate the elongation of pollen tubes, thereby opening up a path for fertilization. The use of other gibberellic acid can not only reduce physiological fruit drop and increase fruit setting rate, but also delay and reduce the emergence of summer shoots.
④ Promote uniform expansion of young fruits.
⑤ Promote uniform coloring of fruits. Usage plan: fruit expansion period, color change period: brassinolide (8000~13000 times) + potassium dihydrogen phosphate (500 times).
⑥ Improve the ability of crops to resist adversity, such as drought resistance, cold resistance, disease resistance, salt and alkali resistance, and waterlogging resistance. Especially in the current situation of more extreme weather, when applying fungicides, insecticides, and acaricides, adding brassinolide at the same time can not only increase the efficacy of the drug, but also improve the resistance of crops.
⑦ Relieve drug damage, which can help plants quickly remove harmful substances in the body and help restore growth.
Brassinolide is applied to peanuts to promote growth and increase yield. Peanuts grow steadily, with a large number of fruits per plant, and both 100 fruit weight and 100 kernel weight are heavy. So how to use brassinolide in peanuts?
How to use brassinolide in peanuts
Brassinolide improves the cold resistance of peanut seedlings. Soak peanut seeds in a 0.01~0.1 mg/L brassinolide solution for 24 hours to promote germination and increase the content of amino acids, soluble sugars and chlorophyll. At the same time, treatment with brassinolide solution can slow down the degradation of chlorophyll and reduce the accumulation of malondialdehyde, a product of membrane lipid oxidation, which can effectively improve the resistance of seedlings to low temperatures; brassinolide can increase peanut yield. Use 5 grams of 0.01% natural brassinolide aqueous solution and add 15 kg of water. Start spraying at the beginning of flowering (ovary stalk into the soil). After spraying, the growth is stable, the total number of fruits per plant is large, and the weight of 100 fruits and 100 kernels is heavy, which is 22% higher than the control.
Benefits of using brassinolide for peanuts
Reasonable application of brassinolide promotes peanut yield increase
How to use During the flowering period of peanuts (when fruit needles are in the soil in large quantities), it is the transition period from vegetative growth to reproductive growth. At this time, proper control of vegetative growth and promotion of reproductive growth are conducive to increasing peanut yield. Choose an appropriate concentration. A concentration of 1200 times can be selected in the north and 1000 times can be selected in the south. Too high or too low a concentration is not conducive to increasing yield. If the concentration is too high, the vegetative body will be over-controlled, the photosynthetic area will be small, the yield will be small, and the yield will be reduced; if the concentration is too low, the yield increase effect will not be obvious.
It can control the leggy growth of peanut stems. Regardless of the initial flowering period, the flowering period, and the needle period of peanuts, the dwarfing effect of plants can be clearly shown 5 days after spraying. Peanut plants treated for a long time have thick stems, short internodes, compact plant shape, darker leaf color, thicker leaves, and an increased angle between petioles and stems, which increases the light-receiving area. It has a significant inhibitory effect on the flowering of peanuts, and the flowering volume decreases significantly a few days after treatment. The higher the concentration of the drug, the stronger the flower control effect, so the appropriate time must be chosen, otherwise it will lead to a reduction in yield. While inhibiting vegetative growth, it can promote the transport of light products to reproductive organs, accelerate the accumulation of pod substances, and promote the growth and development of reproductive bodies, so as to mature 5 days earlier and increase production by 10%-50%
Spraying brassinolide makes the plants strong and increases the number of pods
How to use After the peanut plants enter the flowering period, the effective needles have all entered the soil, forming "chicken beak fruits", and a small number of them have formed large fruits. Spray with 1200 times of Jiunong brassinolide. It can effectively control the elongation of stems and branches. Until harvest, the length of stems and branches is still 3/5 to 2/3 lower than that of the control. The plant type is compact (stable, strong, short nodes), which is conducive to ventilation and light transmission. The chlorophyll content is generally increased by 24% to 45%. Reducing the ineffective flowers in the late stage by about 29% is conducive to promoting the fullness of pods. The number of fruits per plant increases by 4% to 30%, and the full fruit rate increases by 4% to 10%.
