Embodiment 1
[0069] A preparation method of chelated liquid fertilizer, comprising the following steps:
[0070] First add 13.5 parts of glycine and 20.52 parts of reducing sugar, add 160 parts of water, heat it to 40-80°C for oxidation, in order to control the reaction, slowly add 30 parts of 30% hydrogen peroxide to it, and heat for 15 minutes Above (hydrogen peroxide is heated and decomposed), stirred with a continuous mixer. Then add 15.98 parts of CrCl 3 ·6H 2O, 5.25 parts of sodium selenite. Stir at 80°C for 1 h to obtain the chelated chromium product. The chelated chromium-selenium is brown, and it is a water-soluble chelated chromium-selenium with a pH of 13.
[0071] In 60 parts of chelated chromium-selenium liquids obtained in the above method, dissolve 1 part of real silk refining waste liquid, 1 part of valeric acid, 1 part of acetic acid, and stir for 60 minutes to realize the homogenization of the chelate, and then add 4 parts plant ash (K 2 CO 3 、KHCO 3 ) as potash f...
Embodiment 2
[0073] First, add 3 parts of amino acid mixtures such as glycine, alanine and arginine, 6 parts of reducing sugar, add 50 parts of water, heat it to 45°C for oxidation, and slowly add 5 parts of molybdenum to it in order to control the reaction. 30% hydrogen peroxide, heat over 15 minutes with a continuous mixer. Then add 4 parts of CrCl 3 ·6H 2 O, 1.5 parts of potassium selenite. Stir at 80°C for 1 h to obtain the chelated chromium product. The chelated chromium-selenium is brown, and it is a water-soluble chelated chromium-selenium with a pH of 12.8.
[0074] In the chelated chromium-selenium liquid obtained in the above method, dissolve 1.5 parts of silk refining waste liquid, 1.2 parts of valeric acid, and 1.2 parts of acetic acid, and stir for 60 minutes to realize the homogenization of the chelate, and then add 3 parts of plant ash (K 2 CO 3 、KHCO 3 ) as potash fertilizer, stirred for 60 minutes, added 0.7 parts of ammonium chloride as nitrogen fertilizer, 0.8 par...
Embodiment 3
[0076] First add 1 part of amino acid mixture such as glycine, alanine and arginine, 1 part of reducing sugar, add 30 parts of water, heat it to 60 ° C for oxidation, and slowly add 3 parts of 30% hydrogen peroxide, heat over 15 minutes with a continuous mixer. Then add 1 part of CrCl 3 ·6H 2 O, 0.03 part of sodium selenite. Stir at 80°C for 1 h to obtain the chelated chromium product. The chelated chromium-selenium is brown, and it is a water-soluble chelated chromium-selenium with a pH of 12.5.
[0077] In the chelated chromium-selenium liquid obtained in the above method, dissolve 1.5 parts of real silk refining waste liquid, 1 part of citric acid, 1.2 parts of valeric acid, 1.2 parts of propionic acid, and stir for 60 minutes to realize the homogenization of the chelate, Secondly, add 2 parts of plant ash (K 2 CO 3 、KHCO 3 ) as potash fertilizer, stirred for 60 minutes, added 0.2 parts of ammonium sulfate as nitrogen fertilizer, 0.5 parts of superphosphate (Ca(H 2 ...
