为研究梯田措施对赣北第四纪红壤坡地土壤抗蚀性的影响,通过江西水土保持生态科技园9年的定位观测资料,对5种梯田措施下的土壤抗蚀性变化进行了分析。结果表明:与对照坡地相比5,种梯田措施均具有提高土壤稳定性和降低土壤分散性的作用;水平梯田配合前埂后沟和梯壁植草技术,更利于改善土壤团聚状况,提高土壤团聚度,降低土壤分散率和侵蚀率。前埂后沟和梯壁植草式水平梯田适宜在红壤坡地推广。
In order to study the influence of terrace measures on the soil anti-erodibility of Quaternary red soil sloping fields in northern Jiangxi Province, the changes of soil anti-erodibility under five kinds of terraced measures were analyzed based on the 9-year observation data of Jiangxi Soil and Water Conservation Ecological Science and Technology Park. The results showed that compared with the control slope, the terraced rice measures had the effects of improving the soil stability and reducing the soil dispersibility. The combination of the terraced fields and the pre-ditch furrow and the steppe grafting technique could improve the soil reunion and soil reunion Degree, reduce soil dispersion and erosion rate. The ditch and ladder before the ditch and grass-planting horizontal terraces suitable for promotion in the red slope.
