Amino acid fertilizer produced by hydrolysis or fermentation contains a large number of small molecular organic compounds, so it has been developed rapidly as a chelating agent to develop new multifunctional fertilizer. The chelation of amino acids and trace elements is more studied. Inorganic micro fertilizer has poor absorption biochemical function, is easy to be fixed by soil, has obvious antagonistic effect between trace elements, and has low utilization rate, which is difficult to meet the needs of plant growth; Using EDTA, citric acid and tartaric acid as chelating agents to produce chelated micro fertilizer is very expensive. The multi-element micro fertilizer containing Mo, Zn, Cu, Fe and Mn has been prepared, which has the characteristics of resisting interference, alleviating the antagonism between metal ions, good chemical stability and easy to be absorbed and utilized by plants. Moreover, the amino acid after the reduction of metal ions also has nutritional effect and is also a high-quality nitrogen fertilizer to promote plant growth. Amino acid chelated micro fertilizer is the most ideal micro fertilizer for crop growth. It has been used in agricultural production as a new fertilizer. At present, there are products combining amino acid pesticides and fertilizers, which can not only fertilize, but also kill insects and sterilize. Therefore, it is the requirement of ecological agriculture and the inevitable trend of agricultural sustainable development to systematically carry out the functional research of amino acid fertilizer, give full play to the potential of amino acid and improve its utilization rate and biological potency.
Amino acid fertilizer produced by hydrolysis or fermentation is a fertilizer with compound amino acids as the main body, and contains sugar, protein or bacteria and other metal ions. Studies have shown that the fertilizer effect of mixed amino acids is greater than that of single amino acids. The fertilizer effect of amino acid groups composed of some single amino acids with good fertilizer effect is still high, while the fertilizer effect of amino acid groups composed of some amino acids with poor fertilizer effect is still low. It is considered that there is still a problem of optimization of amino acid composition. When protein hydrolysis or fermentation products are actually used as amino acid fertilizer, they are generally mixed amino acids, but the types and concentrations of amino acids in the waste liquid of different processes and different amino acids are different. Therefore, the fertilizer efficiency of the same crop is also different, so there is also the problem of optimization. How to further optimize the composition and structure of fertilizer according to crop needs, adjust the proportion of each component to balance each other, and make the varieties diversified and specialized should be explored and tested in practice.
In short, the continuous research on the production and application of amino acid fertilizer by hydrolysis or fermentation of agricultural waste has opened up more and more new sources of raw materials and provided a new scientific basis for the scientific development and application of amino acid fertilizer. Because the raw materials and processes of amino acid fertilizer production are very different, and the components are comprehensive and complex, the research on the production and application of amino acid fertilizer is a complex system engineering, involving chemistry, chemical industry, biochemistry, soil nutrition, plant physiology and other disciplines, which has a very broad development space.
