| Abstract: |
| A field test in Gangu was carried out by setting up three treatments including whole film casing mode bunch (M1), whole film no overburden bunch (M2), and conventional tillage (CK), to investigate the effects of whole film casing mode bunch on soil microbial activities, nutrient contents and yield of winter wheat. Results showed that compared with CK, C and N of soil microbial biomass were increased by 29.87% & 21.42%, and 20.59% & 16.57% by M1 and M2 during the whole growing stage of winter wheat. In addition, compared with CK, M1 could significantly increase sucrase and urease activities at different growing stages, while resulted in different alkaline phosphatase activity. C and N of soil microbial biomass and enzyme activities were positively correlated with the winter wheat growth stages in each treatment. After harvest, M1 treatment could significantly increase winter wheat yield and soil available nutrient contents. In conclusion, M1 can significantly promote soil microbial biomass, enzyme activities and winter wheat yield. |
