| 摘 要： | 以上海郊区不同区域、不同种植年限的设施菜地为研究对象,针对茄果类和叶菜类两种主要作物轮作模式,通过现场调查和采样分析,研究了设施大棚土壤次生盐渍化现状.结果表明:设施菜地土壤含盐量平均为4.68 g/kg,比露天菜地和自然土高4倍左右,次生盐渍化现象明显,且茄果类种植的设施菜地土壤含盐量显著高于叶菜类.设施菜地土壤含盐...

| Abstract: | Taking the protected vegetables fields with different planting years in different districts of Shanghai as study objects,the status of soil salinization for main cropping modes of solanaceous vegetables and leaf vegetables were explored by site investigation and smaple analysis.The results indicated that the average salinity of the soil in the protected vegetables fields were 4.68 g/kg,which appeared significant salinization and were 4 times higher than the soil salinity in open vegetables fields and the na... |
