摘    要:对陇东黄土高原地区庆阳市周边各县蔬菜大棚土壤性质进行了测定分析。结果表明,随着连作年限的增加,温室土壤盐分表聚和酸化现象明显,土壤主要养分含量有增加的趋势。其主要原因是偏施化肥,不重视有机肥,常年连作,不合理灌溉等。建议采取限制化肥用量,增施有机肥,改进施肥技术,科学灌溉,合理轮作等措施,改良温室土壤。

关 键 词:大棚蔬菜  连作  土壤理化性质  防治措施

Abstract:Soil samples under plastic shed vegetables in Longdong and its surrounding areas on the Loess Plateau were analyzed. Results showed that both soil salt accumulation and acidulation in topsoil were evident and the amounts of main soil nutrients are increased. The reasons for the change are the over applied fertilizer, poorly added organic manure, continuous cultivation, irrational irrigation, etc. We should increase organic manure, limit mineral fertilizer application, improve fertilizing practice, perform irrigation and drainage scientifically, and undertake rational rotation in the future.
Keywords:plastic shed vegetable  continuous cultivation  soil physical and chemical property  changing trend
