| Abstract: |
| The effect of different kinds of intercropping with fruit and grass (crop) on soil microorganisms and en-zyme activities were studied in Zhanggutai Town, Zhangwu County of Liaoning Province from 2007 to 2008 . The results
showed that the soil microbe numbers and enzyme activities of three kinds of intercropping followed peanut > millet >
ephedra in the whole growth stages, all higher than monoculture . Furthermore, differences between the three treatments and the monoculture were greatly significant. Correlations between microorganisms and enzyme activities in most treat-ments were significant or greatly significant. The numbers of bacteria, fungi and actinomycete were increased and the ac-tivities of urease , phosphatase and catalase were all enhanced significantly after intercropping. Consequently, intercrop-ping could improve soil micro-environment and soil quality. |
