Embodiment 1
[0040] A green organic fertilizer for preventing corn pests, which is prepared from the following raw materials in parts by weight: 130 parts of cow dung, 75 parts of chicken manure, 55 parts of corn stalks, 35 parts of fungus residue, 15 parts of vermicompost, and 2 parts of EM bacteria agent , 3 parts of synergist, 2 parts of compound starter, 25 parts of attapulgite.
[0041] Said, the composite fermentation agent is prepared by the weight ratio of 1:1:1.2 from Azotobacter rufica, Bacillus subtilis and Trichoderma harzianum.
[0042] As mentioned, the synergist is prepared from porous magnetic chitosan microspheres, polyethylene glycol monomethyl ether and sodium naphthalene acetate in a weight ratio of 1:3:0.8.
[0043] Described, porous magnetic chitosan microsphere is made by following steps:
[0044] 1) Mix ammonia water, nano ferric oxide, carboxymethyl chitosan and Tween-20 evenly, seal and soak for 3 hours, heat in a water bath at 50°C and stir until carboxymethyl c...

[0058] A green organic fertilizer for preventing corn pests is prepared from the following raw materials in parts by weight: 100 parts of cow dung, 80 parts of chicken manure, 60 parts of corn stalks, 40 parts of fungus residue, 10 parts of vermicompost, and 1 part of EM bacterial agent , 3 parts of synergist, 2 parts of compound starter, 30 parts of attapulgite.
[0059] Said, the compound fermentation agent is prepared by the weight ratio of 1:0.8:1.4 from Azotobacter rufica, Bacillus subtilis and Trichoderma harzianum.
[0060] Said synergist is prepared from porous magnetic chitosan microspheres, polyethylene glycol monomethyl ether and sodium naphthalene acetate in a weight ratio of 1:2:1.
[0061] A kind of preparation method of the green organic fertilizer that prevents corn pest is made by following steps:
[0062] 1) Crushing the corn stalks to a length of ≤5 cm, mixing them evenly to obtain crushed stalks;
[0063] 2) Use urea to make a urea aqueous solution with a...
Embodiment 3
[0070] A green organic fertilizer for preventing corn pests is prepared from the following raw materials in parts by weight: 150 parts of cow dung, 70 parts of chicken manure, 50 parts of corn stalks, 30 parts of fungus dregs, 20 parts of vermicompost, and 3 parts of EM bacterial agent , 3 parts of synergist, 2 parts of compound starter, 20 parts of attapulgite.
[0071] Said, the composite fermentation agent is prepared by the weight ratio of 1:1.2:1 from Azotobacter rufica, Bacillus subtilis and Trichoderma harzianum.
[0072] Said synergist is prepared from porous magnetic chitosan microspheres, polyethylene glycol monomethyl ether and sodium naphthalene acetate in a weight ratio of 1:4:0.6.
[0073] A kind of preparation method of the green organic fertilizer that prevents corn pest is made by following steps:
[0074] 1) Crushing the corn stalks to a length of ≤5 cm, mixing them evenly to obtain crushed stalks;
[0075] 2) Use urea to make a urea aqueous solution with a...
