合理轮作是提高土壤肥力的有效途径之一。浅瘦低产田是在长期粗放经营,施肥量少,不合理耕作等生产条件下形成的,对于大面积的浅瘦低产田地区,实行合理轮作,不仅是用地养地的需要,也是为发展一年三熟创造良好的土壤条件。本试验的目的就是通过水旱轮作,在轮作周期穿插安排绿肥作物等措施,探索一个既能发挥土地生产潜力、增加经济效益,又能改土提高土壤肥力的耕作轮作制度。

Rational rotation is one of the effective ways to improve soil fertility. Shallow and low-yielding fields are formed under the conditions of long-term extensive operation, small amount of fertilizer and irrational tillage. For large areas of light and low-yield fields, the rational rotation is not only necessary for land use, but also for development Three years to create good soil conditions. The purpose of this experiment is to explore a farming rotation system that can not only exert the potential of land production, increase economic benefits, but also improve soil fertility by arranging arrangements of green manure crops through the rotation and rotation of crops and water and rotation.
