Potassium-boron-selenium fertilizer capable of promoting growth of fruit trees and degrading residual pesticide

Abstract

The invention discloses a potassium-boron-selenium fertilizer capable of promoting the growth of fruit trees and degrading residual pesticide. Seleninic acid is neutralized by potassium hydroxide, so that potassium selenite is obtained; diboron trioxide is dissolved in water, and is mixed with the potassium selenite, and thereby potassium-boron-selenium reagent with the PH value between 7.0 and 8.8 is prepared. The potassium-boron-selenium fertilizer has the multiple fertilizer effects of selenium fertilizer and conventional potash fertilizer and boron fertilizer, and when the potassium-boron-selenium fertilizer is sprayed on the surfaces of the leaves of fruit trees, not only can the fruit-setting rate be increased, but also residual pesticide can be degraded and the selenium content of fruits can be increased.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a potassium boron selenium fertilizer which promotes the growth of fruit trees and degrades residual pesticides. Background technique [0002] Fruit trees need to spray a variety of fertilizers and pesticides from germination to flowering and fruiting, especially during the period from flowering to fruit maturity. If fertilizers or pesticides are not sprayed in time and in place, it will lead to only flowering but no fruit setting or fruit taste and hue , poor nutrition, and the residual pesticides on the fruit cannot be degraded, endangering people's health. However, selenium fertilizer and boron fertilizer have been widely used in recent years as new varieties. Selenium fertilizer not only has a significant effect on increasing production, but also has The metal binding force is very strong, and it can combine with the heavy metal on the surface of the fruit to form a stable compound, which has ...
