[0040]A preparation method of an anti-caking microbial fermented organic fertilizer, comprising the following steps:
[0041] Preparation steps of fermented organic matter: Take pond mud and rice straw with a water content of 40-55%, mix them, sterilize at high temperature and cool down, insert activated cellulolytic bacteria and yeast, and ferment naturally at room temperature for 10-15 day, turning once every 24 to 28 hours in the first week, and turning once every 12 to 18 hours thereafter, after the fermentation is completed, dry until the moisture content is below 35%, and crush to obtain fermented organic matter;
[0042] The preparation steps of Bacillus amyloliquefaciens fermentation product: take the activated Bacillus amyloliquefaciens, use the mixture of bran, rice bran and corn flour as the fermentation substrate, and add 0.5-1% potassium nitrate, 0.3- 0.8% ferric sulfate and 1-1.5% potassium hydrogen phosphate, control the water-material ratio to 1: (0.7-0.8), and...
