Document Type and Number:
WIPO Patent Application WO/2022/222357
Kind Code:
A1
Abstract:
Disclosed in the present invention are a soil conditioner and a preparation method therefor. The soil conditioner is obtained by granulation, air drying/drying, and sieving of a straw fermentation product and a calcium magnesium phosphate fertilizer. The preparation method comprises: cutting straw, adding a straw fermenting agent for fermentation, fermenting at normal temperature and normal pressure for 3-10 days, carrying out solid-liquid separation on the fermentation product, drying the solid part of the fermentation product, and then mixing same with the calcium magnesium phosphate fertilizer, grinding the mixture for 10-30 min, using the liquid part of the fermentation product as a granulation assistant, transferring the ground powder into a granulator for granulation, adding the granulation liquid accounting for 1-5% of the weight of the ground powder for granulation, air-drying/drying, and sieving to obtain the soil conditioner having the biological activity. According to the present invention, the substance produced by fermentation of the straw can activate the soil and improve the absorption of the calcium magnesium phosphate fertilizer by the crops. The liquid obtained by fermentation of the straw has good adhesion, and can improve the granulation effect of the calcium magnesium phosphate fertilizer. The use of the straw waste has good economic benefits and social benefits.
