Abstract

The invention relates to a compound amino acid fertilizer synergist which is suitable for a drop irrigation or microspray irrigation system, and a preparation method of the compound amino acid fertilizer synergist. The method comprises the steps of preparing a mixed catalyst, preparing a mixed amino acid salt, preparing a polymeric amino acid salt, preparing auxiliary materials, preparing the compound amino acid fertilizer synergist and the like. After the compound amino acid fertilizer synergist is adopted, the root activity of corns at the seedling stage is remarkably improved by more than 35%; compared with common urea, the urea added with the compound amino acid fertilizer synergist is capable of remarkably increasing the kernels per spike and the hundred-grain weight of the corns respectively by 15.5% and 3.8%, the yield is increased by 19.7%, and the apparent utilization rate of nitrogenous fertilizer is improved by 9.85%.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical fertilizer efficiency enhancement. More specifically, the present invention relates to a compound amino acid fertilizer synergist suitable for drip irrigation and micro-sprinkler irrigation systems, and also relates to a preparation method of the compound amino acid fertilizer synergist. 【Background technique】 [0002] The utilization rate of chemical fertilizers in my country is generally low. The average utilization rate of nitrogen fertilizer is about 30%, the seasonal utilization rate of phosphorus fertilizer is about 25%, and the utilization rate of potassium fertilizer is about 50%. Fertilizer science and technology workers have done a lot of research on ways and methods to improve fertilizer utilization, and achieved certain results, but there are still problems such as complex fertilizer production process, high cost, inconvenient use, and difficulty in popularizing and applying fertili...
