水土流失是自然过程,农业耕作会加速水土流失过程。不注重水土保持的传统耕作方式会使水土流失超过黑土土壤承受能力,进而使黑土土壤生产力下降,严重时可使黑土地丧失农用价值。“东北黑土地会在50年内消火吗”的疑问道出了东北黑土地问题的严重性和社会对此问题的关注。在诸多的保护黑土地措施中,保护性耕作是最值得借鉴的。保护性耕作不仅能有效地保持土壤和水资源,也能降低成本、提高产量和效益。与传统的耕作制度相比,保护性耕作可在
Soil and water loss is a natural process and agricultural farming will speed up soil erosion. Without focusing on the traditional farming methods of soil and water conservation, water and soil loss will exceed the capacity of black soil so that the productivity of black soil may decline. In severe cases, black soil may lose its agricultural value. “The Northeast black earth will fire you within 50 years?” The questions raised the seriousness of the problem of black land in northeast China and society’s concern on this issue. In many measures to protect the black land, conservation tillage is the most worth learning. Conservation tillage not only effectively maintains soil and water resources, but also reduces costs and increases yields and benefits. Compared with the traditional farming system, conservation tillage is available
