Abstract

The invention relates to polyaspartase diammonium and a production method and application thereof. The polyaspartase diammonium comprises polyaspartic acid or a salt thereof, diammonium phosphate, amino acids and biological agents. The polyaspartase diammonium has the advantages that the fertilizer effect of phosphoric fertilizers can be improved, the utilization ratio of phosphoric and nitrogenous fertilizers is increased, the absorption of nutrient elements, such as nitrogen, phosphorus and trace elements, of plants is promoted, the growth of root systems is promoted, the environmental pollution is reduced, and soil is activated and improved.

Description

technical field [0001] The invention relates to nitrogen and phosphorus fertilizers, in particular to a polytetracycline diammonium and its production method and application. Background technique [0002] my country is a big producer and consumer of chemical fertilizers. As we all know, nitrogen fertilizers are prone to leaching and runoff, so the use rate of ordinary nitrogen fertilizers is only 30%, and about 70% of water-soluble phosphate fertilizers will be fixed by heavy metals in the soil. It is only about 30%. It is estimated that about two-thirds of the soil in my country is deficient in phosphorus. The main reason for phosphorus deficiency is that the content of available phosphorus in the soil is insufficient, and a large amount of phosphorus applied to the soil is stored in the soil in an ineffective state. stand up. Therefore, in order to meet the phosphorus needs of crops, only a large amount of phosphorus fertilizers can be applied. Over time, phosphorus fertili...
