河南省安阳地区温室大棚土壤次生盐渍化日趋严重,其成因:从内因看,土壤具有积盐的趋势或已积盐在一定深度;从外因看,主要是因为农业灌溉不当。对此,必须充分利用合理的灌溉制度,因地制宜地建立生态农业结构,对土壤要采取精耕细作、深翻掺沙渗水等措施,才能达到改良大棚土壤盐渍化的效果。
The secondary salinization of soils in greenhouse in Anyang area of Henan Province is becoming more and more serious. The causes are as follows: from the perspective of internal cause, the soil has the tendency of accumulating salt or has accumulated salt at a certain depth; from the external point of view, it is mainly because of improper irrigation of agriculture. In this regard, we must make full use of reasonable irrigation system, according to local conditions to establish eco-agricultural structure, the soil to be intensive farming, deep plowing sand seepage and other measures to achieve the effect of improving greenhouse soil salinization.
