Supplementing essential amino acids, stimulating and regulating plant growth, promoting plant growth, and promoting nutrient absorption. The metabolism function of the plant is enhanced, the photosynthesis is improved, the development of the root system of the plant is promoted, and the growth and the propagation of the plant are accelerated. The fertilizer containing an amino acid is a fertilizer containing a specific amount of an amino acid-based substance. When applied to soil, amino acid-containing fertilizers have the functions of improving disease resistance of fertilization targets and improving quality of fertilization crops. At present, most of fertilizers containing amino acid are prepared by hydrochloric acid, but the preparation method by hydrochloric acid needs severer production conditions and has high production cost, so that the biological fertilizer containing amino acid is not easy to popularize.
Amino acid can produce a large amount of mycoprotein in the fermentation process, the prior art generally prepares the mycoprotein into feed, the application value is low, the application channel is narrow, the applicant further studies the utilization of the mycoprotein, the utilization of the mycoprotein comprises nitrogen source components or amino acid fertilizers prepared into culture media, for example, Chinese patent ' CN201410519206 ', a fertilizer prepared by threonine fermentation waste ' treats the mycoprotein for preparing amino acid chelated fertilizers, wherein the method for preparing the amino acid chelate comprises the following steps: drying mycoprotein, crushing the mycoprotein into powder by a crusher, then placing the powder into a reaction kettle, adding 6-8mol/L hydrochloric acid, stirring and hydrolyzing the raw materials at 60 ℃ for 12-15 hours at a stirring speed of 100 r/min, neutralizing residual hydrochloric acid by potassium hydroxide after the reaction is finished to obtain an amino acid aqueous solution, and then adding a catalyst into the reaction kettle according to a molar ratio of amino acid to metal ions of 3: 1, adding metal ions at the temperature of 40 ℃, for 30min and at the pH of 7.0, carrying out a chelation reaction, and finally concentrating, drying and crushing a chelated product to obtain an amino acid chelate; the method adopts acid hydrolysis to obtain L-amino acid, but tryptophan is completely destroyed by boiling acid; a small portion of amino acids containing hydroxyl groups such as serine or threonine is cleaved; the amide groups of the asparagine and glutamine side chains are hydrolyzed to carboxyl groups. The products of the prior art which adopts alkaline hydrolysis are D-type amino acid and L-type amino acid, and because many amino acids are damaged in different degrees in the hydrolysis process, the yield is not high. Therefore, the obtained free amino acid part belongs to right helix by hydrolyzing the mycoprotein with strong acid and alkali, the activity is poor, the absorption by plants is not facilitated, and tryptophan used for synthesizing the plant growth hormone is damaged. The existing literature adopts hydrochloric acid with higher concentration to treat mycoprotein, which is easy to damage amino acid, and results in lower nutritive value of hydrolysate.
