Abstract

The invention discloses a controlled-release microbial fertilizer containing polyglutamic acid. The microbial fertilizer is prepared from the following raw material components: diatomite, straw powder, animal waste, polyglutamic acid, urea, plant ash, compound microorganism bacterium liquid and EM probiotics. The invention has the advantages that the raw material formula is reasonable in use, the form of mixing the organic carrier and the inorganic carrier is adopted, the defect of lack of nutrition of the inorganic carrier can be overcome, the problem of high processing cost of the organic carrier can also be overcome, and the product quality can be ensured while the production and use cost is reduced; the polyglutamic acid contained in the raw material components can promote the development of roots and stems of crops and can obviously improve the quality of the crops, and the raw material components have good water retention and moisture preservation capacity and can well improve the physical and chemical shape of the soil, so that the land can be continuously cultivated and is free of pollution.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a controlled-release microbial fertilizer containing polyglutamic acid. Background technique [0002] Microbial fertilizer is developed according to the principles of soil microecology, plant nutrition, and the basic concept of modern "organic agriculture". Use a fertilizer that is used more frequently. Microbial fertilizer can greatly increase the content of medium and trace elements in the soil, reduce the application of nitrogen, phosphorus, potassium and other medium and trace elements; at the same time, it can also increase soil organic matter, accelerate the degradation of organic matter into nutrients that can be absorbed by crops, and greatly improve soil quality. Fertility, reduce the amount of chemical fertilizers, friendly to the environment. Polyglutamic acid is a new generation of plant nutrition accelerator, which has the functions of reducing fertilizer loss,...
