Problems solved by technology

[0005] Most of the existing selenium-enriched foliar fertilizer products are selenite or a mixture of selenite and nitrogen, phosphorus, and potassium fertilizers. After spraying, they cannot be wetted and attached to the leaves of crops, and cannot effectively absorb selenium-enriched nutrient solutions. , so the waste is relatively high, and the crops at the production site cannot meet the requirements once sprayed; and the content of other elements in the existing selenium-enriched foliar fertilizer is small, which cannot promote the growth of plants very well

Abstract

The invention discloses a selenium-containing trace element foliar fertilizer for selenium enriched cultivation of crops and a use method thereof. The foliar fertilizer is obtained by mixing of borax, ammonium molybdate tetrahydrate, chelated iron, sodium selenite, potassium fulvate and a selenium yeast extract. The use method includes: mixing the raw materials in proportion, then dissolving the fertilizer in a certain amount of water, conducting adding under stirring till the fertilizer is completely dissolved, then adding organic silicon, and finally adding a proper amount of water to perform spray application on leaf surfaces uniformly. The selenium-containing trace element foliar fertilizer provided by the invention can be used cooperatively with other bulk drugs to promote absorption of selenium-containing fertilizer by crop leaves so as to enhance the content of selenium element in crops, thereby improving the content of selenium element in crop products.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a selenium-containing trace element foliar fertilizer for selenium-enriched cultivation of crops and a use method thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. The content of selenium in the human body is very small, but it has extremely important physiological functions. It has anti-cancer, anti-cancer, anti-oxidation, protects the body from damage by active oxygen free radicals, and protects the heart. , anti-hepatic necrosis, improve immunity, delay aging and other pharmacological effects. A variety of diseases in the human body, such as high blood pressure, diabetes, and cardiovascular and cerebrovascular diseases, are all related to selenium deficiency. [0003] The distribution of selenium in the natural environment is extremely uneven. The soil in two-thirds of my country is in a state of selenium deficie...
