Abstract:Through analyzing dry land actual situation,and taking steps as irrigation and drainage engineering,soil improvement project,agricultural and chemical measures,soil properties and environmental factors which affected quality of cultivated land was changed ,farm irrigation was guaranteed and drainage was good,soil texture,soil profile form and soil pH was suitable for rice growth,in the same time,anic content was raised. accordingly,cultivated land quality of dry land reform paddy field was improved.
Key words:Cultivated land quality;Soil texture;Dependability of irrigation anic matter;Soil amendment
随着经济社会的发展,土地整治的总体目标由原来单一追求耕地数量向数量、质量、生态并重转变。十二五期间,全国土地整治的工作目标中明确指出,经整治后的基本农田提高1个等级[1]。近年来,为落实中央关于“占优补优、占水田补水田”的要求,江西省开始着手实施“旱地改水田”土地整治项目。如何提高改造后水田的质量,真正达到“占优补优”,是亟待研究的课题。
耕地质量的好坏主要通过农用地分等体现,可以用等别的提高程度说明耕地质量提升的情况[2]。在江西省耕地质量等级因素指标体系中,水田分等评价因素包括土壤因素和环境因素。其中,土壤因素涉及土壤质地、剖面构型、有机质含量、土壤pH值,环境因素包括排水条件和灌溉保证率。本文主要根据晚稻分等因素确定旱地改水田耕地质量提升的工程措施。
