Boron granular fertilizer

The application of boron fertilizer is very good for crops, but nothing can be excessive. If boron granular fertilizer  is applied too much, it will cause fertilizer damage of boron fertilizer, which is not only unprofitable, but also harmful to crops. Therefore, it is very important to strictly grasp the amount of boron fertilizer. How much boron fertilizer will be needed for one mu of land?

This dosage is: generally, 200-500g / 650m2 of high content base boron fertilizer should be applied, while 1000-1500 times of spraying boron fertilizer should be applied, and the application dosage and spraying concentration should not be increased arbitrarily.

The amount of boron fertilizer is not only important, but also important. Boron granular must be applied evenly. Slow release base boron granular fertilizer  is required to be applied evenly in the whole field, especially on annual cash crops such as rice, rape, cotton, watermelon and vegetables.

The spraying time of different types of boron granular fertilizer  should also be well controlled. Attention should be paid to the spraying time of instant boron fertilizer. Generally, flowering and fruiting crops choose to spray before flower bud differentiation, before flowering and after flowering to young fruit stage, so as to achieve the goal of promoting flower bud differentiation, pollination and fertilization and fruit development. At the same time, special attention should be paid to the mixing of boron spraying and other agents. Scientific methods should be paid to avoid affecting the effect and even poisoning the crops.

The fertilizer is different from the fertilizer used in ordinary times, and some crops will be more sensitive when used. However, cereal crops such as rice, wheat and corn are not sensitive to boron. The application of boron fertilizer has obvious effects on preventing and controlling the symptoms of "bud but not flower" of cotton, "flower but not solid" of rape and "flower and fruit falling" of fruit trees. It has effects on flowering and Fruiting of crops, accelerating carbohydrate transport in the body, enhancing photosynthesis and forming legume root nodules It can improve the ability of drought and cold resistance of crops, and is conducive to preventing physiological diseases of crops.
