| 摘 要： | 通过在滨海泥质重盐碱地区挖深60cm的集雨池，并覆盖不同厚度的河沙（5cm、10cm和15cm）和苇草（15cm），研究了利用雨季自然降雨洗盐和冬春季节抑制返盐的效果。结果表明：各覆盖处理均能起到一定的洗盐、抑盐效果，且洗盐效果和抑盐效果随河沙厚度的增加而提高，但以覆盖15cm苇草处理的洗盐、抑盐效果最佳。

| Abstract: | Rainfall-collecting pools with the depth of 60 cm were built and different thickness of river sand mulch （5 em, 10 cm and 15 cm） or reeds mulch （ 15 cm） was applied on the coastal shale saline land, to study the salt-washing effect of natural rainfall in rainy season and the salt accumulation restraining effect in winter and spring. The results showed that the mulch cover treatments all had certain salt-washing effect and salt restraining effect, and the salt control effects were enhanced along with the increasing thickness of river sand, but 15 cm reeds mulch performed the best. |
