| Abstract: | For the purpose of exploring planosol and its improvement,Four-stage Plough was used to subsoil planosol to study change of soil microorganisms and soybean yield.The results showed that compared with the control,with Four-stage Plough could increase the number of bacteria by 311.03%,the number of fungi by 289.31%,the number of actinomycetes by 356.39%.The microbial amount was increased by 320.55%.Moreover,it could increase plant height,pot number per plant,grains number per plant and soybean yield by 6.71%. |
