针对新修梯田存在的土壤肥力下降严重、作物产量不稳等问题,目前国内快速培肥的方法主要有生物培肥、化学培肥、物理培肥、管理措施培肥等关键技术。调查研究了增施肥料、秸秆还田、深耕翻种植、地膜覆盖种植、合理轮作套种等培肥技术在宁南山区新修梯田的应用情况与效果,提出了适宜宁南山区新修水平梯田的快速培肥措施,为提高宁南山区新修水平梯田生产力提供了技术依据。
In view of the serious soil fertility decline and crop yield instability in newly-repaired terraces, the key methods of rapid fertilization in China are bio-fertilization, chemical fertilization, physical fertilization and management fertilization. The application and effect of fertilizing techniques such as fertilization, straw returning, deep plowing and tillage, mulching and mulching cultivation and reasonable rotation interplanting techniques were investigated and investigated in newly-built terraced rice fields in southern Ningxia. The application of newly applied terraced rice fields in southern Ningxia Rapid fertilization measures to provide a technical basis for improving the productivity of newly-built terraced fields in mountainous areas of southern Ningxia.
