What kind of fertilizer is boron fertilizer? What are the functions of boron fertilizer? How to apply boron fertilizer? It is understood that plants need to be fertilized during the planting process, and boron is one of the essential nutrients for plants. So, what kind of fertilizer is boron fertilizer? How to apply?

What is boron fertilizer?

Boron fertilizer is a fertilizer with a specified amount of boron to provide plant nutrients for its main functions. Conventional boron fertilizer refers to boron chemical products based on borax, boric acid, and boron-magnesium fertilizers as trace element fertilizers for agriculture.

What are the functions of boron fertilizer

1. Promoting effect. Boron can promote the operation of carbohydrates. The boron content in plants is appropriate, which can improve the supply of organic matter to various organs of crops, make crops grow normally, and increase the rate of seed setting and fruit setting.

2. Special effects, boron has special effects on the fertilization process. Its content in pollen, stigma and ovary, can stimulate the germination of pollen and the elongation of pollen tube, so that pollination can proceed smoothly. When crops are deficient in boron, anthers and filaments shrink and pollen cannot be formed, showing the symptoms of "flowers without fruit".

3. Regulating function. Boron can regulate the formation and operation of organic acids in plants. When boron is deficient, organic acids accumulate in the roots, the cell differentiation and elongation of the root tip meristem are inhibited, and corkization occurs, causing root necrosis. Boron can also enhance the drought resistance and disease resistance of crops and promote early maturity of crops.

How to apply boron fertilizer?

Boron fertilizer can be used as base fertilizer, seed fertilizer and top dressing. When used as a base fertilizer, it can be mixed with nitrogen fertilizer and phosphate fertilizer and applied together, or applied separately, but pay attention to applying evenly to avoid excessive local concentration to cause poisoning. On boron-deficient soil, 0.5-1 kg of boron fertilizer can be applied per mu. Fertilizer effect usually lasts for 3-5 years; when making seed fertilizer, you can soak seeds with 0.01%-0.1% borax or boric acid aqueous solution for 6-12 hours. Grains and vegetables can use 0.01%-0.03% solution, and rice can use 0.1% solution. , Use 0.4-1 g of borax or boric acid per kilogram of seeds when dressing the seeds; when making extra-root topdressing, you can spray with a 0.1%-0.2% borax or boric acid solution, which is usually carried out when the crop is transferred from the vegetative growth period to the reproductive growth period. In other words, it is appropriate to take the crop before and after flowering.
