摘要

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.

Abstract

The steep sloped}and of purple hilly area of Sichuan basin account for 15% of total area.In order to utilize the steep sloped-land completely and rationally

the following designed approaches for soil and water conservation of sloped}and were investigated cover straw(CS)

collect water with pond and pits(CW-PP)

plant straw}locks along contour(PSB) and plant rye}rass(PR G).The results shown that all this practices bear a certain efficacy as expected.Among this alternatives

PRG ranked first in increasing soil water content for the research conditions

and PSB

CS ranked second. From the aspect of preserving the stability of soil moisture

the desired results appeared in CS and CWPP

from which some rainfall-intercepted was discharged during a few days after raining.
