基于人工降雨试验,研究不同残茬覆盖度在4°坡对黑土坡面水土保持效益的影响。试验设置3个平行条件,分别为4个雨强(30,60,90,120 mm/h),5个残茬覆盖度(15%,35%,55%,75%以及裸土对照组)以及2种土壤初始含水量(8%和30%,分别对应干、湿运行)。结果表明:对黑土坡面进行残茬覆盖处理,能够起到抑制土壤产流产沙的作用,且覆盖度越高,其抑制作用越明显。15%,35%,55%,75%覆盖度下保水效益可以分别可以达到30%,27%,57%,72%;保土效益分别可以达到36%,53%,89%,94%。根据保水保土效益与覆盖度的关系建立了指数函数关系式。与保水效益相比,残茬覆盖处理的保土效益更为明显。残茬覆盖不仅能提高黑土养分,更是保护黑土的有效方式。
Rainfall simulation experiments were conducted to study the effects of different residue coverage on soil and water conservation of the black soil on 4° slope. Three parallel conditions were set up in the experiment
which were five residue coverage (bare
15%
35%
55% and 75%)
four rainfall intensities (30
60
90 and 120 mm/h)
two initial soil moistures (8% and 30%
corresponding to dry and wet operation). The results showed that residue cover had positive effects on reducing the soil erosion and the runoff and sediment production of the black soil
and the higher the coverage
the more obvious the inhibition. The water conservation benefits under the 15%
35%
55% and 75% residue coverage could reach 30%
27%
57% and 72%
respectively. The soil conservation effects under the four residue coverages could reach 36%
53%
89% and 94%
respectively. Exponential functions were established between the soil and water conservation benefits and the residue coverage. Compared with the water conservation benefit
the soil conservation benefit of residual cover was more obvious. Residue cover could not only increase the nutrient contents
but also an effective way for the black soil protection.
