Introduction

Brassinolide is a novel endogenous steroid hormone in plants, which can significantly increase plant nutrient growth and promote fertilization at very low concentrations. Brassinolide is internationally recognized as the most efficient, broad-spectrum, and non-toxic plant growth regulator with the highest activity. It has a dual effect of promoting plant cell division and elongation, promoting root development, enhancing photosynthesis, increasing crop chlorophyll content, promoting effective absorption of fertilizers by crops, assisting in the growth of disadvantaged parts of crops, promoting root and seedling strength, flower and fruit preservation.

peculiarity
Highly effective plant hormones, at very low concentrations, can significantly increase the growth of plant nutrients and promote fertilization.

Dosage form
0.01% cream, 0.01% powder, 0.01% soluble liquid, 0.0075% water,0.004% cream. Among them, 0.01% soluble liquid has the highest promotion value. Extracted from rapeseed flowers, it is the sixth largest growth hormone secreted by plants themselves.

Practical effect
It has multiple functions such as rooting, promoting growth, raising seedlings, strengthening seedlings, protecting seedlings, greening of yellow leaf disease, promoting fertilization, preserving flowers and fruits, promoting fruit expansion and early maturity, alleviating disease and drug damage, coordinating nutrition balance, resisting drought and cold, reducing pesticide residues in crops, and enhancing crop stress resistance. The first-aid effect on dead seedlings, root rot, standing dead and quenching caused by repeated cropping, disease, drug damage, freezing damage and other reasons is remarkable, and the application of 12-24 hours is obviously effective, and the vitality is quickly restored. Suitable for food crops, cash crops, vegetables and fruits, etc., to promote growth and increase yield.

Action characteristic
Brassinolides are one of the most bioactive steroid compounds. They are widely found in plants. In each stage of plant growth and development, it can not only promote vegetative growth, but also facilitate fertilization. Synthetic brassinolide has high activity, which can be absorbed by the leaves, stems and roots of plants, and then conducted to the site where it functions. Some believe that it can increase the activity of RNA polymerase, increase the content of RNA and DNA, some believe that it can increase the potential difference of cell membrane and the activity of ATPase, and some believe that it can strengthen the effect of auxin. At present, there is no consensus on the mechanism of action. It acts in a very small concentration, is an efficient plant growth regulator, at a very low concentration, that is, can significantly increase the growth of plant nutrients and promote fertilization. Some of its physiological effects have some characteristics of auxin, gibberellin, and cytokinin:

1, promote cell division, promote fruit expansion. It has a significant promoting effect on the division of cells, and promotes the horizontal and vertical growth of organs, so as to play the role of expanding fruit.

2, delay leaf aging, keep green for a long time, strengthen chlorophyll synthesis, improve photosynthesis, and promote leaf color deepening green.

3. Break the apical dominance, promote the germination of lateral buds, promote the differentiation of buds, promote the formation of lateral branches, increase the number of branches, increase the number of flowers, improve the fertility of pollen, and thus increase the number of fruits and increase the yield.

4. Improve crop quality and marketability. Induce parthenocarpy, stimulate ovary enlargement, prevent falling fruit, promote protein synthesis, increase sugar content and so on.

Usage method

1. Soaking wheat seed with 0.05-0.5mg/kg medicine for 24h significantly promoted root and plant height, and leaf surface treatment with this concentration at tillering stage could increase tillering number. Wheat with 0.01-0.05mg/kg of liquid medicine for foliar spray during pregnancy, the effect of increasing production is the most significant, generally can increase production by 7%-15%.

2. Spraying the whole corn plant with 0.01mg/kg of liquid medicine before corn extraction can increase the yield by 20%, and post-spinning treatment also has the effect of increasing the 1000-grain weight.

3. Other crops can also be used for rape bud stage and young pod stage. Fruit flowering stage, young fruit stage, vegetable seedling stage and flourishing stage; The effect of increasing yield was good at flowering and young pod stage.

The vast high-tech training on brassicolide:

1. The combination of chloropylurea (KT-30) and brassicolactone has high efficiency and high yield

KT-30 has remarkable fruiting effect. Brassicin microtoxicity: basically non-toxic, harmless to people, high safety, is a green pesticide. Brassinolide can promote growth and increase production. The combination of KT-30 and brassicin lactone can not only promote the expansion of the fruit, but also promote the growth of the plant, protect the flower and fruit, prevent the cracking of the fruit, and effectively improve the quality of the fruit. When used in wheat and rice, it can increase the thousand grain weight and achieve the effect of increasing production. KT-30 belongs to the cell division class of products, the main function is to promote cell division, promote fruit expansion. It has a significant promoting effect on the division of cells, and promotes the horizontal and vertical growth of organs, so as to play the role of expanding fruit.

Brassicolide broad spectrum: The use of some plant growth regulators is limited, and improper use will cause serious drug harm. Brassicin lactone can be applied in all plants, including bean sprouts, mushrooms, etc., can also be used, the effect is obvious.

2. The compound combination of brassinolide with foliar fertilizer and gibberellin, a common compound variety component that has appeared in recent years, is gibberellide + brassinolide, and brassinolide + indole butyric acid can promote seedling growth, fruit expansion, fruit increase and fruit increase, and body sleep bud germination, seedling growth, growth and income.

Brassinolide can be used in combination with gibberellin and foliar fertilizer to preserve flower, preserve fruit, strengthen fruit, beautify fruit and promote growth. The mixture ratio of brassinolide and gibberellin was about 1/199 or 1/398 [3], and foliar spraying was performed according to the concentration of 4ppm after the mixture and potassium dihydrogen phosphate with concentration of 1000ppml-2000ppm [4]. If the leaf color of the plant is light and the fruit set is relatively more, high potassium humic acid leaf fertilizer can also be added. Spraying fruit preservative is generally sprayed about 15 days before the second physiological drop, and then sprayed once every 15 days, usually 2-3 times.

If the brassicin lactone can be combined with gibberellin ratio adjusted to 1/(1000-1500) times, after a day of treatment, it was found that the growth rate of the pentaphylla can be significantly increased by 4-7 times, and the leaf color is fresh green, the plant is in the flourishing period of growth and no fruitless growth, according to the plant characteristics, the plant is in the flourishing period of growth is not conducive to the formation of flowers. -- Note: This paragraph is not original and is for reference only

4. Brassinolide + ethephon

Ethephon could reduce maize plant height, promote root development and resist lodging, but inhibited ear development obviously. Brassinolide promotes corn ears. Compared with the single treatment, the treatment of corn with the combined solution of brassinolide and ethefenolate has the advantages of significantly enhancing root vitality, delaying leaf senescence in the later stage, promoting ear development, dwarfizing plants, thickening stems, high cellulose content, enhancing stem toughness, and greatly reducing the lodging rate under strong wind conditions. The increase was 52.4% compared with the control.

5. Brassinolide + aminothrin (DA-6)+ ethephon

Its preparation is 30% and 40% water agent, diluted 1500 times, the amount of 20-30ml, used in 6-8 leaves of corn. It is a popular plant growth regulator for corn growth control in recent years, and it is also the best plant growth regulator for controlling corn plant height. The product overcomes the side effect of small corn cob and thin stalk when growth inhibitor is used to control corn flourishing long time, and effectively transfers nutrients to reproductive growth, so the plants are dwarfed, green, large and uniform, the plant roots are developed, and the ability to resist falling is strong.

6. Brassinolide + polybulobuzole

Brassinolide + polybulozole, a soluble powder, is mainly used for the control and expansion of fruit trees. It is also a more popular plant growth regulator for fruit trees in recent years, and its application in fruit trees is on the rise.

7. Brassinolactone + nexylamine

Brassinolide can enhance photosynthesis and promote root development. Arthrothylamine can coordinate the growth and development of cotton plant, control the growth of cotton plant, delay leaf senescence and improve root vitality. The results showed that the combined preparation of brassinolide and arthropyl amine in the bud stage, the initial flowering stage and the full flowering stage had a better effect than the two treatments alone, and had a significant synergistic effect, which was manifested as increasing chlorophyll content and photosynthetic rate, promoting root vitality and controlling plant growth.

8. Brassinolide + arthropyridozole + polybulozole can control the growth of growth quickly, but the duration of effect is short. Polybulozole has the characteristics of controlling vegetative growth, shortening the interval between segments, promoting reproductive growth and long duration of effect. When the two are used in combination, the drug effect lasts long, while controlling the growth, increasing the yield and resisting lodging.
