| 摘 要： | 选用已进行4 a温室夏季种植甜玉米、菜豆及其秸秆还田试验的温室黄瓜连作土壤，于2009年继续进行相同的处理，研究了温室夏季填闲作物及秸杆还田对黄瓜连作土壤养分和微生物代谢功能的影响。结果表明，种植甜玉米秸秆还田处理能减小土壤容重，改善土壤通透性。夏季填闲及秸秆还田处理对土壤养分和微生物的影响在秋冬茬表现较明显，能增加土壤中有效磷含量，种植菜豆处理（秸秆还田和不还田）能增加土壤有效钾含量。填闲作物及秸秆还田处理还能提高土壤微生物代谢活性，改变土壤微生物对单一碳源的利用能力。

| Abstract: | After 4-year experiment under greenhouse condition,we studied the effects of sweet corn and common bean,including their straw returning,on cucumber(Cucumis sativus L.)soil nutrients and microbial metabolic activity.The results showed that after planting sweet corn with its straw returning in summer,soil bulk density decreased,which is helpful to soil permeability.Effects of all treatments on soil nutrients and microbial metabolic activity were obvious in autumn winter season,such as increasing soil availabl... |
