Embodiment 1
[0024] A compound fertilizer made of wheat bran is made of the following raw materials in proportion by weight: 30 parts of wheat bran additives, 10 parts of mineral fertilizers, 5 parts of carrion insect additives, 2 parts of Bacillus subtilis, and 3 parts of yeast 2 parts of compound microbial bacteria, 0.8 parts of photosynthetic bacteria, 1 part of copper sulfate, 1 part of ammonium nitrate, 1 part of urea, 2 parts of biogas residue, 5 parts of lake mud, and 3 parts of oil cake.
[0025] Further, the wheat bran additive is composed of wheat bran powder, rice bran, corn germ meal, and modified corn starch in a weight ratio of 10:3:6:5.
[0026] The modified cornstarch is made from cornstarch and natto gum, and its preparation method is: add water to the cornstarch to form a starch slurry with a concentration of 30%, then add natto gum, and adjust the pH of the system with 3% sodium hydroxide solution value to 8, heated to 40°C and kept stirring to react. After the reaction,...
