Method for reducing soil colletotrichum gloeosporioides

The invention discloses a method for reducing colletotrichum gloeosporioides in soil, which comprises the following steps: mixing vinegar residue and charcoal, and uniformly spreading the mixture on the earth surface. Compared with the prior art, the vinegar residues and the biomass charcoal are laid on the earth surface, the vinegar residues become living places of colletotrichum gloeosporioides, and the biomass charcoal can adsorb the colletotrichum gloeosporioides. Through practical research comparison, when the vinegar residues and the biomass charcoal are paved on the earth surface, the abundance of colletotrichum gloeosporioides and fusarium belonging to the colletotrichum gloeosporioides in the soil is greatly reduced. 本发明公开了一种消减土壤炭疽病菌的方法，包括使用醋糟和生物炭混合，均匀铺撒在地表。与现有技术相比，本发明采用醋糟和生物质炭铺施地表，醋糟成为炭疽病菌的生活场所，生物质炭可以吸附病菌。经过实践研究对比，醋糟和生物质炭铺施地表，土壤中的炭疽病菌及致炭疽病菌的镰孢属丰度大大减少。
