次生盐渍化

渠灌区平均每年积盐17.0mg/kg，达到重度土壤次生盐渍化需要30～60年，中度土壤次生盐渍化需约1～30年。

Under the condition of canal irrigation , salt content of 17.0mg/kg is accumulated in cultivated layer annually , and severe secondary salinization will emerge 30-60 years , and medium secondary salinization will emerge 1 ~ 30 years .

秸秆处理还可降低土壤的电导度（EC），遏制土壤次生盐渍化。

The salinity ( EC ) of soil in plastic house was decreased by corn straw application .

通过盆栽实验的方法，研究了三种秸秆有机肥对次生盐渍化土壤的EC值、硝酸根离子含量和油菜生物量的影响。

EC value , NO_3 ~ - concentration and rape biomass were investigated in salinity soil applied with three straw manures by pot culture .

而施用秸秆肥料M3，在增加油菜生物量的同时显著降低土壤盐分含量，减轻了土壤的次生盐渍化程度。结果表明，三种秸秆有机肥均能提高油菜对盐渍化的耐受能力，增加其生物量。
