摘要
采用田间试验,在夏季休闲期(7～8月)分别进行填闲小麦、石灰氮消毒和秸秆反应堆处理,研究了不同填闲处理对连作6a和8a的温室黄瓜生长、产量及根区土壤的脲酶、碱性磷酸酶、蔗糖酶和过氧化氢酶活性的影响。结果表明,与常规休闲对照相比,各处理对黄瓜生长均起到了一定的促进作用,填闲小麦和石灰氮消毒处理的效果更明显。填闲小麦能够显著提高根区土壤脲酶、蔗糖酶和过氧化氢酶活性,石灰氮消毒和秸秆反应堆处理对土壤蔗糖酶和过氧化氢酶活性有促进作用,而对土壤脲酶和碱性磷酸酶活性则有抑制作用。夏季休闲季种植小麦在促进土壤酶活性、提高土壤肥力方面操作方便且效果较好。
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.
