A kind of Polytian bacterial fertilizer and its production method and application

Abstract

The invention relates to a polyaspartic acid bacterial fertilizer and a production method and application thereof. The polyaspartic acid bacterial fertilizer comprises polyaspartic acid or salts thereof, bacillus megatherium, colloid bacillus, bacillus licheniformis, bacillus subtilis, humic acid, and amino acid. The polyaspartic acid bacterial fertilizer can be used for improving the soil, helping crops to absorb nutrient elements including nitrogen, phosphorus, potassium and trace elements, promoting the growth of roots, reducing contamination to environment, activating the soil and reducing the use amount of the fertilizer.

Description

technical field [0001] The invention relates to a bacterial fertilizer, in particular to a polytian bacterial fertilizer and its production method and application. Background technique [0002] Now in agricultural production, chemical fertilizers have been widely used. At present, China has become the largest producer and consumer of chemical fertilizers in the world. Although the arable land area accounts for only 7% of the total arable land area in the world, the amount of chemical fertilizers used in China is close to that of the world. one-third of the total. For example, nitrogen fertilizer, nitrogen fertilizer through volatilization. The average loss is 60% through leaching and runoff. The massive loss of chemical fertilizers has caused a series of environmental problems, and the irrational application of nitrogen fertilizers in some highly intensive agricultural areas in the north has led to excessive nitrate in groundwater. In southern China, excessive application...
