| 摘 要： | 通过自制土壤冲蚀槽,并进行人工模拟降雨试验,研究了稻秆编织地表覆盖物对坡地土壤侵蚀和小麦产量的影响。结果表明:在坡度为27°,每次降雨强度为0.5~0.8mm/m in,小麦整个生育期降雨量为672mm条件下,与无覆盖等高种植和顺坡种植相比,应用秸秆编织地表覆盖物分别减少地表径流量28.36%~44.49%和25.26%~36.74%;分别减少土壤侵蚀55.66%~85.44%和12.13%~47.43%;增加小麦产量36.08%和27.95%。

| Abstract: | Effects of rice straw covering net on soil erosion and wheat yield were studied with self-designed soil erosion boxes under simulated rainfall.The experiment results showed that in comparison with no straw covering net treatments in both contour and down slope planting,when a 0.5-0.8mm/min rainfall intensity each time and total 672mm rainfall during whole wheat growth stage were given,and the slope was fixed at 27°,the runoff and soil sediments of the treatment with rice straw covering net were decreased by 28.36%-44.49%,25.26%-36.74% and 28.36%-(44.49%),25.26%-36.74%,respectively,and the wheat economic yield was increased by 36.08%和27.95%. |
