摘　　要：对大棚土壤采用土壤深翻 +秸秆覆盖和土壤深翻 +秸秆覆盖 +土壤改良剂 2种改良措施研究土壤的改良效果 ,结果表明 ,2种改良技术均能明显改善和消除一些土壤障碍因子 ,能使土壤 >0 .2 5mm水稳性团粒含量显著增加 ,表层土壤水溶性盐含量明显下降 ,土壤通透性改善 ,土壤疏松不板结 ,显著提高黄瓜经济效益。以土壤深翻 +秸秆覆盖The field experiments in the effect of two kind integrated soil amelioration techniques on plastic greenhouse soil improvement were carried out. The results showed that two kind methods of integrated soil amelioration techniques could notable improve or eliminate many soil obstacle factors in plastic greenhouse for cucumber growth, vegetable production and economical benefits. The technique of deep plough + straw cover + soil conditioner will have a good application prospects in the area of plastic greenhouse soil amendment.
