[0030] The application also provides a preparation method of a fertilizer biological synergist, comprising the following steps:
[0031] Mix chitosan oligosaccharide extract, algae oligosaccharide extract, alanine, cysteine, histidine, lysine, glycine, EDTA chelated iron, boric acid, manganese sulfate, magnesium sulfate, and zinc sulfate in proportion , and then adjust the pH to 3 to 4 to obtain a mixed solution;
[0032] The mixed solution is dispersed and emulsified and then spray-dried to obtain a fertilizer biological synergist.
[0033] In the above preparation process, various raw materials are first mixed, and then one or more of hydrochloric acid, acetic acid and citric acid are used to adjust the pH of the mixture to 3-4.
[0034] According to the present invention, the above-mentioned mixing is emulsified by a dispersing emulsifier for 10-30 min, and the rotating speed is 800-1200 RAM, so as to ensure more uniform mixing.
[0035] The present application adopts the...
Embodiment 1
[0038] The preparation method of the fertilizer biological synergist for promoting photosynthesis and preventing physiological yellowing adopted in this example is as follows: 35 parts of chitosan extract (degree of polymerization 3-7, content 95%, solid content 15%), seaweed Oligosaccharide extract (degree of polymerization 2-8, content 93%; solid content 15%) 30 parts, 1 part alanine, 0.5 part cysteine, 0.5 part histidine, 0.2 part lysine, 0.8 part glycine parts, 4 parts of EDTA chelated iron, 2 parts of boric acid, 1 part of manganese sulfate, 5 parts of magnesium sulfate, and 6 parts of zinc sulfate were mixed uniformly, and the pH was adjusted to 3 with boric acid, and then stirred for 20 minutes by a dispersing emulsifier. The micro-particle pressure spray drying tower is prepared into micro-particles. The inlet temperature of the drying tower is 150°C and the outlet temperature is 75°C.
