Selenium-enriching agent and its usage and use

Abstract

The selenium-enriching agent of the present invention consists of selenium containing inorganic compound and phosphate in certain ratio. When it is used, the selenium-enriching agent is dissolved in 50-90 times of water, and the solution is sprayed to the surface of plant, including food crop, economic crop and vegetable, in its growth period. It consists of soluble inorganic salts and may be absorbed easily by plant, and it has no residue and no environmental pollution.

Description

technical field

[0001] The invention relates to a plant growth regulator, in particular to a selenium-enriching agent capable of increasing the selenium content in plants. Background technique

[0002] Selenium is an essential micronutrient element for humans and animals. It has many important physiological functions, the most important of which is that selenium participates in the formation of glutathione peroxidation in the form of selenocysteine ​​(SeCys) in humans and animals. Phytase (GSH-Px), thereby removing excessive active oxygen free radicals in the body. Exogenous selenium can induce the increase of GSH-Px activity and the activity of catalase. When the body is in a state of selenium deficiency, the activity of GSH-Px decreases, causing the accumulation of lipid free radicals and peroxides, which may induce abnormal lipid peroxidation (LPO), leading to cell membrane damage, tissue damage, and tumorigenesis. The study found that within a certain range of selenium...
