Title:
METHOD FOR IMPROVING PROPERTIES AND EFFICIENCY OF TROPICAL SANDY FARMLAND SOIL
Document Type and Number:
WIPO Patent Application WO/2022/267261
Kind Code:
A1
Abstract:
The present invention provides a tropical sandy farmland soil composition, comprising the following raw materials in percentage by weight: 55-65% of an earthworm cultivation product, 8-12% of a compound bacterial preparation, and the balance of fine phosphorite powder. The compound bacterial preparation is formed by mixing Paecilomyces lilacinus, Bacillus subtilis, Trichoderma viride, and Bacillus megaterium in a weight ratio of 2-3:2-3:1-2:1-2; and the earthworm cultivation product is obtained by using a culture medium obtained by natural fermentation and air-drying of cow dung and corncobs to cultivate earthworms, adding a conditioner during cultivation, and separating earthworms and the earthworm cultivation product after cultivation. According to the present invention, the earthworm cultivation product, fine phosphorite powder, and compound bacterial preparation are effectively combined, so that the prepared composition forms a physical-chemical-biological multi-phase synergistic reaction chain in tropical sandy soil, thereby improving the physical structure, microbial diversity, and nutrient retention capacity of the sandy soil, and achieving the comprehensive effects of fertilizing soil and increasing the phosphorus content and disease resistance of crops.
