Embodiment 1
[0019] A soil conditioning organic fertilizer for plant disease prevention and control, made of the following raw materials in parts by weight: 28g of zeolite, 40g of animal excrement, 7g of plant ash, 8g of urea, 4g of humic acid, 2g of Bacillus subtilis preparation, 9g of chitin powder, seaweed Salt 9g (sodium alginate 6g, calcium alginate 3g), trace elements 1.5g (niacin 0.2g, folic acid 0.1g, pantothenic acid 0.05g, Fe0.3g, Mn0.2g, Cu0.2g, Zn0.4g, Se0 .05g).
[0020] The total number of effective viable bacteria of the Bacillus subtilis preparation is ≥220 million spores / g. The preparation method of the chitin powder is as follows: drying and pulverizing the recycled shrimp and crab shells for later use; adding water 7-9 times the weight of the shrimp and crab shell powders, and treating with ultrasonic waves, and then standing to swell; 3-4% of the weight is added with a compound enzyme to hydrolyze the protein, then coarsely filtered, centrifuged, and finally finely fil...
