| 摘 要： | 为探究秸秆覆盖对滨海盐碱地土壤含盐量、水分、pH的动态变化规律,进行秸秆覆盖试验(FG),并以不覆盖秸秆作为对照组(CK)。结果表明,FG在0~20cm,20~40cm土层土壤盐度分别下降了16.09%和7.26%,土壤含水量分别增加了69.21%和59.08%。由此可得,秸秆覆盖能有效改良滨海盐碱地土壤,减少了土壤水分蒸发损失,提高了水分利用效率,在一定程度上抑制了土壤中可溶性盐分的表聚作用,从而达到改良滨海盐碱地的目的。

| Abstract: | To study the effect of straw mulching on the dynamic changes of soil salt content, moisture and the pH value in coastal saline-alkali soil, a straw mulching test (FG) was carried out, and no mulching was used as CK. The results showed that straw mulching could reduce the soil salt content by 16.09% and 7.26% in 0-20 and 20-40 cm soil layer, and increase the soil water content by 69.21% and 59.08%, respectively. Thus, straw mulching could effectively improve coastal saline-alkali soil, reduce the soil moisture evaporation, improve the water use efficiency, and to a certain extent, inhibit surface accumulation of salt, so as to achieve the purposeof improving the coastal saline-alkali land. |
