Abstract:
Cucumber was used as material，the effect of different cover of plastic film and straw on soil organic carbon，C/N and microorganisms in greenhouse were studied，to explore the best treatment and internal mechanism.The results showed that treatment of 0.72 kg?m-2 straw with plastic film mulching was ideal，which significantly improved soil organic carbon content and C/N in the early and late stage，and improved the number of five kinds of microorganisms of early and late stage and bacteria of early stage.The number of soil bacteria was significantly positive correlated with the organic carbon content and C/N of 0-20 cm，and the C/N of 20-40 cm was negatively correlated with the number of fiber decomposing bacteria but positive correlated with that of nitrogen fixing bacteria.
