本试验利用经增温剂发酵熟化的牛粪与土的混合物作为双孢蘑菇的覆土材料 ,结果显示 :熟化牛粪中的粪草粉部分与土以 1∶ 1.5的比例混合 ,能比对照细泥垄糠土增产 5 %左右 ,而牛粪中的粪粉部分对产量有负面影响 In this experiment, the mixture of cattle manure and soil, which was fermented and matured by the warming agent, was used as the soil cover material of Agaricus bisporus. The results showed that the part of the manure powder and the soil in the aged manure were mixed with the soil in the ratio of 1: 1.5, Mound furrow increased about 5%, while manure in cow dung partially affected the yield negatively
