摘要

[目的] 研究不同农田植被条件下的水土侵蚀特征

为该区作物种类选择提供参考。[方法] 2013年在位于东北典型黑土带上的黑龙江省红星农场径流小区内

开展了玉米、大豆、大豆-玉米间作3种农田植被条件下的地表径流和土壤侵蚀特征研究。[结果] 玉米的径流拦蓄和土壤侵蚀控制的效果最好

间作次之

大豆位居最后;玉米和间作模式的地表径流分别较大豆减少了15.8%和10.7%

土壤侵蚀量亦分别减少了10.47%和5.35%。[结论] 在较低降雨强度下玉米和间作的减流减沙效果差别不甚明显

在较高强度下玉米和间作减流减沙效果明显好于大豆。

Abstract

[Objective] In order to provide references for the selection of suitible crops for black soil areas

to analyze the rill erosion characteristics of different cropland.[Methods] The study of surface runoff and soil erosion characteristics under three different cropland planting of corn

soybean and soybean-corn belt cropping

was carried out in the runoff plot of Hongxing State Farm in Heilongjiang Province located in the northeast typical black soil belt in 2013. [Results] For the performances of runoff retaining and sediment yield control

corn performed the best

while the intercropping of soybean-corn followed it

and soybean took the last. Compared to soybean

the surface runoff decreased 15.8% and 10.7% under the cultivation modes of corn and intercropping of soybean-corn; in corresponding to the soil loss

decreased 10.47% and 5.35%

respectively. [Conclusion] The control of surface runoff and soil loss between corn and soybean-corn belt cropping was not significant under the relatively low-intensity rainfall conditions. Whereas the control of surface runoff and soil loss under soybean-corn belt cropping was much better than that under soybean in the high-intensity rainfall condition.
