| 摘 要： | 为研究地表覆盖材料对甘肃盐渍化土壤水盐运移及枸杞生生长产量的影响,在统一沟灌6 000 m3·hm-2的基础上,以不覆盖为对照(CK),设置覆盖黑膜(T1)、草帘(T2)、无纺布(T3)3种材料处理;监测覆盖处理后土壤含水率、盐分含量和pH,分析土壤水盐变化。结果表明:地表覆盖黑膜、草帘、无纺布均能削弱地表蒸发,抑制地表返盐,黑膜处理土壤含水率最高、含盐量最低,无纺布处理土壤含盐量最高;覆盖草帘处理枸杞成活率、保存率、株高、冠幅和产量均为最高,第2年草帘处理枸杞产量为1.86t·hm-2,是对照的1.4倍,比黑膜、无纺布处理分别高10.7%、8.1%。因此,沟灌条件下覆盖草帘适宜于该地区盐渍土农作物种植。

| Abstract: | In order to study the effects of surface mulching on saline soil water-salt migration and the growth,yield of wolfberry.Three materials covered with plastic film mulching(T1),straw(T2)and non-woven fabric(T3)were set on the basis of unified furrow irrigation of 6 000 m^3·hm^-2.The control site was covering nothing(CK),soil water and salt changes were analyzed by monitoring soil water moisture,salt content,and pH change.The results showed that the surface covered with plastic film mulching,straw and non-woven fabric could weaken the surface evaporation and inhibit the secondary salinization occasionally.The soil of plastic film mulching treatment had the lowest salt content and the highest moisture,the soil of non-woven fabric treatment had the highest salt content.Covering the straw treatment survival rate,preservation rate,plant height,crown width and yield were the highest.The yield of straw treatment in the second year was 1.86t·hm^-2,which was 1.4times of CK,10.7% and 8.1% higher than plastic film mulching and non-woven fabric.The yield of straw treatment was the highest in all treatments.Therefore,covering the straw could inhibit surface evaporation and secondary salinization,which was conducive to growth and yield improvement under the furrow irrigation. |
