Future prospects for the use of amino acid fertilizers
Apr 27, 2018

The amino acid fertilizer produced by hydrolysis or fermentation contains a large number of small molecular organic compounds, so it is used as chelating agent, and the development of new type of multifunctional fertilizer has been developed rapidly. The most studied is amino acid trace element chelating Hefei. Inorganic fertilizer has poor absorption of biochemical function, easy to be fixed by soil, and there is obvious antagonism between trace elements, low utilization rate and difficult to meet the needs of plant growth. It is very expensive to use EDTA, citric acid and tartaric acid as chelating agents to produce chelating micronutrient fertilizer. Mo, Zn, Cu, Fe, Mn and other micronutrient fertilizers have been prepared, which have the characteristics of resisting interference, alleviating the antagonism between metal ions, good chemical stability, easy to be absorbed and utilized by plants, and the loss of amino acid itself after the reduction of metal ions is also nutritious and is also a high quality nitrogen fertilizer for the growth of plants. . Amino acid chelated micronutrient fertilizer is the most ideal microelement fertilizer for crop growth. It has been applied to agricultural production as a new type of fertilizer. At present, there are also products that combine amino acid pesticides with fertilizers, which can both fertilize and sterilize insects. Therefore, it is an inevitable trend for the sustainable development of agriculture to carry out the research on the function of amino acid fertilizer, give full play to the potential of amino acid, improve its utilization and biological titer, and be the requirement of ecological agriculture.

The amino acid fertilizer produced by hydrolysis or fermentation is composed of compound amino acids and contains sugar, protein or bacteria and other metal ions. Some studies have shown that the fertilizer efficiency of mixed amino acids is greater than that of single amino acids. The effect of some amino acid groups, which is composed of some single amino acids, is still high, and the amino acid groups of some amino acids, which have poor effect, are still low, and the amino acid composition is still preferred. The problem. The actual application of protein hydrolysis or fermented products as amino acid fertilizers is generally mixed amino acids, but the kinds and concentrations of amino acids in the waste liquid of different processes and different amino acids are different, so there is also a difference in the fertilizer efficiency of the same crop, so there is also an excellent choice. How to optimize the composition and structure of the fertilizer according to the needs of the crops, and adjust the proportion of the components to each other, so that the varieties of the production are diversified and specialized, and should be explored and tested in practice.

In a word, the continuous research on the hydrolysis of agricultural wastes or the production of amino acid fertilizer and its application has opened up more and more new sources of raw materials, which provides a new scientific basis for the scientific development and application of amino acid fertilizer. The production and application of amino acid fertilizer is a complex system engineering, which involves chemical, chemical, biochemical, soil nutrition, plant physiology and other disciplines. It has a very broad development space, because the raw materials and processes of amino acid fertilizer are different and the ingredients are complex and complex.
