Description

technical field

[0001] The invention relates to a compound fertilizer, in particular to a fertilizer suitable for use on leaves. technical background

[0002] Chinese scientists have measured the selenium content of soil samples from 1094 counties and cities in my country, and the results show that only 1 / 3 of the counties reach the internationally announced normal critical value of 0.1 mg / kg, and the remaining 2 / 3 areas are selenium-deficient areas. Wherein the content ≀ 0.02mg / kg accounts for 29%, is the severe selenium deficiency area.

[0003] Selenium is an essential element in life activities. Selenium deficiency is closely related to various human diseases, and it is one of the causes of Keshan disease and Kaschin-Beck disease. Selenium is an integral component of glutathione peroxidase. Glutathione peroxidase participates in the oxidation process of the human body, which can prevent the oxidation of unsaturated acids and prevent aging and tissue hardening caused by...
