摘要

在重庆忠县坡度为11°的紫色土柑橘园

设中耕、覆盖、生草和清耕4种处理

用自动雨量记录仪记录降雨过程及降雨量

通过径流小区集水池测量不同耕作方式的地表径流量

取水样测定和统计地表径流中泥沙含量和流失量。结果表明:4种处理的地表径流量为清耕>生草>覆盖>中耕

相互处理间差异极显著

清耕年地表径流量分别比生草、覆盖和中耕高8.88%

10.79%和22.51%;处理间的地表径流水中的泥沙含量差异极显著

生草的泥沙含量分别比覆盖、清耕和中耕的低11.43%

38.00%和60.00%;不同耕作方式间的年泥沙流失量差异极显著

生草的泥沙流失量分别比覆盖、清耕和中耕的低10.84%

46.40%和58.99%。生草栽培可显著减少三峡库区坡地紫色土柑橘园的水土流失。
