摘要: 通过盆栽实验的方法,研究了化肥与腐熟秸杆有机肥对土壤EC、各盐分离子含量以及油菜生物量的影响。结果表明,施用化肥显著增加土壤盐分含量,过量的化肥导致土壤次生盐渍化,降低油菜生物量;施用腐熟有机肥虽然在一定程度上增加土壤EC值和各盐分含量,但是同时显著增加油菜的生物量。

Abstract: Effects of application with fertilizer and decomposed straw manures on salinity soil EC, salt ions concentration and rape yield were investigated by pot culture. The results showed that it could increase soil salt content when applied fertilizer, and excessive fertilizer led to more serious secondary salinity and reduced rape yield. But decomposed straw application increased rape yield as well as soil salt content.
