摘  要:
海门市大棚设施土壤存在一定的盐分积累现象,土壤含盐量是邻近大田的3~4倍,盐分累积在年度内呈现明显的起伏特征,在栽培期间(头年10月到翌年5月),土壤含盐量达0.38~8.03g/kg,平均3.28g/kg;而在撤膜期间(5月─10月),土壤含盐量呈下降趋势,平均为2.07g/kg,降幅达36.9%;年度内阶段性的设施栽培不会发生土壤含盐量多年累积的现象,这是该地区特殊气候条件形成的;采取相应措施可有效控制大棚设施土壤盐分的积累。

摘  要:
Salt accumulation was found to have occurred in greenhouse soils in Haimen, making the salt content therein 3 ~ 4 times higher than in the neighboring open field soil. Salt content in the greenhouse fluctuates significantly within a year, rising up to 0.38 ~ 8.03 g/kg with an average of 3.28 g/kg during the greenhouse operating period (from October to May next year) and falling by 36.9%, down to 2.07 g/kg, during the open cultivation season (from May to October). Severe salt accumulation seldom occurs in the soil under periodical greenhouse cultivation within a year, which may be attributed to the special weather conditions of the region. Greenhouse salt accumulation can be effectively controlled with proper measures.
