Brassinolide is a novel plant growth regulator that was first discovered by American agricultural scientists in 1970. It is unidirectionally targeted compared to the other five growth regulators and is known as the sixth plant hormone. . In agriculture, everyone uses brassinolide to alleviate the phytotoxicity and restore the crop to normal growth. Today, I will analyze this ingredient and hope that everyone can recognize and use brassene lactone correctly.

Three misunderstandings of brassinolide

Falsely considered to be foliar fertilizer

In fact, brassinolide is not a foliar fertilizer, and foliar fertilizer is a nutrient element fertilizer (such as phosphorus, potassium, boron, zinc, rare earth elements, amino acids, etc.). If it lacks such nutrients, it will affect crop growth. Brassinolide itself is not nutritious. It regulates crop growth indirectly by regulating the endogenous hormone system of plants, and has good compatibility with foliar fertilizer.

2. Mistaken to be usable

Many people mistakenly believe that brassinolide has no effect. It is a product that can be used or not. In fact, brassinolide has a comprehensive function. From seed treatment to harvesting, the whole crop can be used.

It can also improve the stress resistance of crops, enhance the ability of crops to resist disease, cold, freeze, drought, sputum, salt and alkali, and prevent premature aging, and reduce the phytotoxicity caused by improper application of pesticides and fertilizers. At the same time, brassinolide has no drug resistance, and for farmers, it can preserve flowers and preserve fruit, and the effect of increasing yield is obvious.

3. Misunderstood as a niche product

This key is how to look at the problem. Li Yongcai, a senior expert of brassinolide, said that all kinds of crops can be used. If only one crop per acre is used, roughly calculate that the brassinolide has a market capacity of 105 billion yuan, which is definitely a big product. .

Cai Zhiwen, a veteran of the industry, also said that the current domestic market capacity of brassinolide is about 1.2 to 1.5 billion yuan, and it is expected to reach 2 billion yuan in five years. With the market's understanding and function of brassinolide, Development, the future will become a billion-dollar product.

The role of brassinolide

Root promotion

It is used as seed treatment or seedbed spraying, which has obvious growth-promoting effects on seedling roots of rice, wheat, corn, broad beans, tobacco, vegetables and other crops. The fresh weight of roots increased by 20%-50% compared with the control, and the dry weight increased by 15%-107%, which showed deep roots and strong seedlings.

2. The nutrition period promotes

Brassinolide has the dual functions of promoting cell division and cell elongation, and can increase the chlorophyll content of leaves, enhance photosynthesis, increase the accumulation of photo-contracted products, and thus have obvious effects of promoting plant vegetative growth, which can be improved. Crop yield.

3. Fertility promotion

Brassinolide can increase the germination rate of pollen, promote the elongation of pollen tube, and facilitate the fertilization of plants, thereby increasing the seed setting rate and fruit setting rate. During the maturity of the crop, the number of grains and the weight of the grain increased, and the melons and fruits showed uniformity of the fruit and improved crop quality.

4. Enhance stress resistance

After entering the plant, brassinolide not only enhances photosynthesis, promotes growth and development, but also stimulates some protective enzyme activities in plants, which can greatly reduce the harmful substances produced by plants under adverse conditions (such as Malondialdehyde, etc.) damage to normal function. A large number of experimental studies and field experiments have proved that brassinolide can indeed enhance the stress resistance of crops, especially in the aspects of drought resistance and low temperature resistance (freezing damage).

5. Relieve phytotoxic

Herbicide, bactericidal insecticide misuse, or concentration ratio is not suitable, it is prone to phytotoxicity, timely use of brassinolide + high-quality foliar fertilizer can regulate nutrient transport, supplement nutrition, reduce damage and accelerate crop growth. Note: When handling phytotoxicity, pay attention to the use concentration of brassinolide. If the concentration is too high, it may aggravate the phytotoxicity.

The effect is magical, but it can't be overstated

Seeing the above effects, do you feel that brassinolide is a legend? However, it is not.

1. Brassinolide is a chemical substance that mimics the structure of sterols. It has a certain concentration of use. If the concentration is too high, it will not only cause waste, but also may cause different degrees of inhibition on crops.

2. The effect is obvious under adverse conditions, so the effect is not good when the crop is in good condition.

3. Individual manufacturers exaggerate the efficacy of their products, resulting in a large difference between the actual effects and publicity effects of farmers. This invisibly severely hindered the further development of the market for brassinolide.

4. The role of brassinolide can not be exaggerated. If the damage of the crop is too serious, it can not achieve the effect of returning to life. In addition, it must be combined with other pesticides and does not have a complete replacement effect.

5. Brassinolide itself has no nutrients, so it is necessary to ensure the supply of nutrients, "water, fertilizer, and regulation" integration, so that brassinolide can play a better role in the plant body.

In short, brassinolide has certain limitations. It cannot be used at will because it has many advantages. We must have an objective attitude and a scientific and rational use method for any product, so that it can exert its good effect. (China Agricultural Materials Media)
