Technical Field

The invention relates to the field of foliar fertilizers, and in particular relates to a selenium-rich biological foliar fertilizer special for rice.

Background

The selenium-rich rice retains all the nutrients of common rice, and has the functions of resisting and preventing cancer, protecting heart, delaying senility, resisting oxidation, eliminating free radicals, raising immunity, etc. Because the special health care function of the selenium-rich rice and the selenium are mineral trace elements necessary for human bodies, and the quality of life of people is improved, the development is rapid in recent years, and organic selenium elements such as Tubo organic selenium fertilizer are required to be selected for producing selenium-rich agricultural products, particularly grain crops with strict requirements in various aspects. The simple substance selenium element in the ionic state is actually adsorbed to a pure biological carrier (yeast) which has bioactivity, is free of heavy metal and non-organic impurities and is relatively indiscriminate by the foliar fertilizer on the premise of a certain degree, and then the foliar fertilizer is produced by utilizing a biological product process. The fertilizer not only has the content of heavy metal non-organic impurities meeting the standard, good biological activity, easy absorption by crops, stable and disordered selenium content of agricultural products, and better quality and yield than common agricultural products, but also has low production cost, and the agricultural products meet the quality requirements of the selenium-rich agricultural products.
