摘　　要：土壤次生盐渍化其成因与地下水水位抬升存在密切关系。土壤次生盐渍化防治的根本措施是调控地下水位。河套地区土壤盐渍化严重,针对研究区的实际情况,本文参考前人研究成果,讨论了临界深度的确定对于防治土壤盐渍化、合理利用水资源和提高农作物产量的实际意义。Secondary salinufication s origin is in connection with groundwater level closely.The basic measure for prevetion of the Secondary salinufication is to sontrol the groundwater level.Salification in Hetao area is serious.Based on Hetao practical situation,groundwater critical depth is brought forward through actual measurement data consulting researched results.The significance of conforming of critical depth in prevention and cure of soil salification,reasonable use of water resource and increase in crop pr...
