为充分开发利用四川盆地丘陵区占总土地面积 15 %的坡坎 ,研究了坡坎的水土保持技术 :稻草覆盖、集水坑洞、种植黑麦草和等高扎稻草埂的效益。结果表明这些措施都有一定效果 ,其中 ,种植黑麦草在试验条件下 ,对提高土壤含水量有较好的作用 ,其次是扎草埂和稻草覆盖。保水效益较好的是稻草覆盖和集水坑洞措施 ,因为它们在雨后几天内能释放其接纳的部分雨水 In order to fully exploit and utilize the slope with a hilly area of ​​15% of the total area of ​​Sichuan Basin, the soil and water conservation technologies of slope ridge were studied: the benefits of straw cover, water collecting hole, planting ryegrass, The results showed that all of these measures have some effects. Among them, the planting of ryegrass in the experimental conditions, to improve soil moisture content has a good effect, followed by Zhacao and straw cover. Better water retention benefits are straw cover and catchment hole measures because they release some of the rainwater they receive over the next few days
