Abstract:: With regard to the soils grown yam for different continuous planting years (0 year, 1 year, 2 years) and different rotation system (yam—wheat), we examined the microbial communities and enzyme activities of soils(0—30 cm) of different tillage patterns. The results showed that: the contents of soil organic matter, total nitrogen, phosphorus and potassium gradually decreased with the increase of yam cropping years, while the yam-wheat rotation mode helped to restore the soil fertility; bacteria was the largest, followed by actinomycetes, fungi was the least in each treatments; compared with the control, bacteria, actinomycetes showed a decreasing trend with increase of yam cropping years. The decline of actinomycetes was significantly greater than that of bacteria, which showed actinomycetes was more sensitive than bacteria with continuous cropping. The quantity of fungi increased at first and then decreased. Continuous cropping can significantly reduce the soil urease, alkaline phosphatase and invertase activity, while the rotation mode can stimulate the activity of the three enzymes. The activities of soil urease and invertase of rotation treatment were significantly higher than those of continuous cropping 2 years of treatment, and the difference was significant (p < 0.05) and extremely significant(p < 0.01), respectively. The study results imply that the continuous cropping will destroy the soil microbial community structure and restrain soil enzyme activity, and the crop rotation can improve soil quality to a certain extent.
