Abstract

A fertilizer assistant is prepared from, by weight, 20-80 parts of polybasic sugar alcohol composition and 20-80 parts of polymeric amino acid composition. The polybasic sugar alcohol composition is prepared from 5-10 parts of mannitol, 10-20 parts of sorbitol, 5-10 parts of xylitol, 20-30 parts of citric acid and 30-50 parts of zinc sulfate. The polymeric amino acid composition is prepared from 30-40 parts of gamma-PGA, 20-30 parts of PASP and 30-50 parts of calcium nitrate. The fertilizer assistant can be applied to solid fertilizer or fluid fertilizer of commercial crops, the weight ratio of the fertilizer assistant to the solid fertilizer is 10-30%, and the weight ratio of the fertilizer assistant to the liquid fertilizer is 20-50%. Small-molecule sugar alcohol and amino acid integrated into biological sources are beneficial for crop root / ex-root absorption, improve the utilization efficiency of traditional fertilizer, neither pollute the environment nor cause potential safety hazards and can prolong the quality guarantee period of crop fruits.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer adjuvant which can be used as a solid fertilizer additive and a liquid fertilizer additive and the application of the fertilizer adjuvant in economic crops. Background technique [0002] The utilization rate of chemical fertilizer is affected by many factors such as the amount of fertilizer applied, the type of fertilizer applied, soil characteristics, crop varieties, etc. It is necessary to take measures to improve the utilization rate of chemical fertilizers. Only by making good use of fertilizers can the production costs of crops be reduced and profits be increased. At present, the utilization rate of fertilizers in my country is generally not high. For example, after the phosphorus in the existing compound fertilizer enters the soil, the effectiveness will drop by 80% in about 35-40 days, which will easily cause waste of resources and pollute the ...
