Embodiment 1
[0009] After saponification of the cottonseed oil feet from the vegetable oil factory to remove neutral oils, 60% of the cottonseed oil feet after saponification and removal of neutral oils and 40% of waste plant ash from biological power plants are fully After stirring, add 10% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 20-35°C, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. After inspection, the product meets the NY525-2002 standard, and the test results are shown in Table 1.
Embodiment 2
[0011] After the rapeseed oil feet from the vegetable oil factory are saponified to remove neutral fats, 50% of the cottonseed oil feet after saponification and removed neutral fats, and 30% of the waste plant ash from the biological power plant are taken based on the total weight of the fermented material After fully stirring, add 20% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 20-35°C, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. , the product was tested and met the NY525-2002 standard, and the test results are shown in Table 1.
Embodiment 3
[0013] After saponifying the soybean oil residues from the vegetable oil factory to remove neutral oils, 55% of the cottonseed oil residues after saponification and removal of neutral oils, and 35% of the waste plant ash from the biological power plant are taken as the total weight of the fermented material. After stirring, add 10% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 5-10°C, and the fermentation time is about 20 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. After inspection, the products meet the NY525-2002 standard.
