The third year' s data were taken into analysis. Comparing with traditional cultivation system (two seasons planting cucumber with fallowing in summer) , planting leafy vegetable and garlic in summer increased the yields of the two crops and the soil microbial biomass carbon content, total microbial population, and sucrase activity, decreased the amounts of soil nematode and root-knot nematode, and maintained a relative high Shannon-Weaver index. Planting crown daisy, garlic, and spinach in summer increased soil sucrase activity by 8.9%, 89.5%, and 36.9%, and the planting of crown daisy and garlic also increased the Shannon-Weaver index by 7.7% and 9.4%, respectively. All the results suggested that catching crop and rotation had definite restoration effects on the soil quality under continuously cropping of cucumber, and the effects of planting crown daisy and garlic were more significant. | | Language | chi | | Pub Type(s) | English Abstract
