摘要

针对云南省山地种植措施不合理

水土资源流失严重的现状

进行了甜玉米间作草带和辣椒的水土保持效应研究。结果表明

在降雨集中的6

8这3个月

间作处理的径流量比单作处理的径流量平均减少了29.08%

侵蚀量平均减少了52.36%。B处理(甜玉米盖膜+牧草)的总径流量比D处理(辣椒单作)减少了85.05%

B处理的总侵蚀量比C(甜玉米盖膜单作)

D处理分别减少了62.58%

63.34%。在极高雨强下

B处理的径流量比D处理减少了75.29%

B处理的侵蚀量比C

D处理的分别减少了81.36%

98.34%。可见

甜玉米间作牧草草带是一种持续利用和保护山地水土资源的有效措施。

Abstract

To examine unreasonable plantation and severe soil and water and soil loss on sloping land in Yunnan Province

a research was conducted on the benefits of soil and water conservation under sweet maize intercropped with green pepper and grass strip. In June

July and August

runoff under intercropping treatment decreased by 29.08% and soil erosion

by 52.36%

as compared with sole cropping; total runoff for the treatment B(sweet maize+grass) decreased by 85.05% as compared with the treatment D(green pepper mono-cropping)

and total soil erosion

by 62.58% and 63.34%

respectively

as compared with the treatments C(sweet maize mono-cropping) and D; and during rainfall of the highest intensity

runoff for the treatment B decreased by 75.29% as compared with the treatment D and soil erosion decreased by 81.36% and 98.34%

respectively

as compared with treatment C and D. The result shows that sweet corn intercropped with grass strip is an effective measure for sustainable use and protection of soil and water resources in a mountainous area.
