Abstract Taking field trial，during July to August，we used catch wheat，lime nitrogen degassing and
straw reactor landfill treatments to study their effects on cucumber（Cucumis sativus L. ） growth，yield and root
zoon urease，alkaline phosphatase，sucrase and catalase activities in 6 years and 8 years continuous cropping in
greenhouse. The result indicated that compairing with the conventional fallow contrast，each treatment had played
certain promoting effect on cucumber growth，catch wheat and lime nitrogen degassing had more obvious effect.
Catch wheat could significantly increase the activities of soil urease，sucrase and catalase. Lime nitrogen degassing
and straw reactor landfill treatments could increase the activities of soil sucrase and catalase，while suppress the
soil urease and alkaline phosphatase activities at the same time. Planting wheat during fallowing season in summer
can easily improve soil fertility with ideal effect.
