Promote root growth
Amino acid fertilizer can regulate crop root morphology,promote root growth. Among them , Tryptophan can promote the synthesis of indoleacetic acid and auxin;Histidine is a catalytic enzyme for cytokinin synthesis, which can promote the synthesis of cytokinin, thus stimulating the division and growth of root tip meristem cells, inducing the formation of adventitious roots, making young roots root fast, making seedlings root fast, main roots grow, and lateral roots increase. Increase the length and volume of roots, promote the absorption of water and nutrients by roots, and facilitate root growth
Increase nutrients utilization
Amino acid can accelerate the rapid cycling , decomposition and release of nutrients in soil, have the functions of nitrogen fixation , phosphorus and potassium release. The stimulation of amino acids increases microorganisms in soil ,accelerates the mineralization of organic nitrogen and activates phosphorus fixed by soil. In addition,glycine is a natural metal chelating agent,which can chelate potassium and microelements in soil, facilitate the elements absorption by crops, improve nutrients utilization.
Improve stress resistance
After absorbing amino acids, the physiological and biochemical functions of crops are enhanced, and the stress resistance is also enhanced. Alanine is resistant to pathogens and can enhance the disease resistance of crops. Arginine and methionine are the precursors of polyamines synthesis of endogenous hormones in crops. Increasing the synthesis of polyamines can improve the salt stress resistance of crops; Lysine, proline and complexine increase the tolerance of plants to osmotic stress, and improve the drought and cold resistance of crops; Phenylalanine can promote the synthesis of lignin, make crop stalks strong, and improve lodging resistance
Improve crop quality
Amino acid can improve the quality of crops, aspartic acid can promote the synthesis of protein, glutamic acid can reduce the nitrate content in crops and improve the safety of vegetables; Serine participates in cell and tissue differentiation, which is beneficial to fruit formation and development; Glycine increases the sugar content of crops and improves the taste of fruits. Isoleucine and leucine are precursors of aromatic aroma, which can increase the aroma of fruits. Phenylalanine is the precursor of anthocyanin synthesis, which can promote the synthesis of anthocyanins, and is conducive to the coloration of fruits in the later stage, and improve the yield. Alanine, glutamic acid, glycine and lysine can promote the synthesis of chlorophyll, regulate the opening of stomata, thereby promoting leaf photosynthesis, enhancing photosynthetic efficiency, promoting the formation of photosynthetic products, at the same time, they can also enhance the transmission capacity of photosynthetic electrons, promote the efficiency of photosynthetic pigments to convert light energy into chemical energy, ensure efficient photosynthesis, and output more products, which is conducive to high yield.
