Studies over the years have shown that amino acid fertilizer can promote the absorption of nutrients by crops and increase the content of nutrients in crops.

  Studies over the years have shown that amino acid fertilizer can promote the absorption of nutrients by crops and increase the content of nutrients in crops.

  Zahir et al. Found that a certain concentration of tryptophan could significantly improve the absorption of N and the concentration of N, P and K in potato tubers, but had no effect on the yield of potato tubers and straw and the absorption of P and K. Arshad et al. [19] showed that soil application of certain concentration of tryptophan would significantly improve the plant height, dry matter quality of stems and roots and biomass of cotton, increase the number of branches, flowers and bolls per plant, and increase the concentration of N, P and K in cotton tissue. Chen Zhende and others studied the effects of soil application of L-tryptophan on the yield and nutrient absorption of potted cabbage. The results showed that soil application of L-tryptophan one week before transplantation could significantly improve the yield and dry matter accumulation of cabbage, significantly promote the absorption of N, P and K by cabbage plants, improve the distribution of n and P in bulb leaves and reduce the accumulation of K in bulb leaves.

  The results of Franken Berger et al. Also showed that after soil application of L-tryptophan, the N absorption of radish, watermelon and melon increased significantly. The results of Chen Mingchang and others showed that after soil application of L-tryptophan and L-methionine, the absorption of various nutrients by maize increased significantly, especially the effect of L-tryptophan; At the same time, the absorption of P, CA, Mg, Fe, Mn, Cu and Zn also increased. The reasons why amino acid multi-element fertilizer can promote the efficient utilization of nutrients by crops may be as follows: ① increase the synthesis of hormones in crops, so as to promote the absorption of nutrients by crops; ② Promote the growth of crop roots and improve the ability to absorb nutrients; ③ Increase the expression of amino acid transporter in crop roots to make it easier to absorb nutrients.
