为了掌握阜南县耕地地力以及中低产田分布情况并研究相应的改良利用措施,以阜南县第二次土壤普查以及测土配方施肥等数据文本资料为基础,在地理信息系统与计算机技术的支持下,对阜南县耕地生产潜力进行划分,并在此基础上根据《全国中低产田类型划分与改良技术规范》(NY/T310—1996)以及阜南县实际情况对阜南县中低产田类型进行二级系统划分。结果表明,阜南县耕地地力可以划分为5个等级,并在此基础上将中低产田划分为三大类型,即干旱灌溉型、渍涝潜育型和渍涝排水型。并针对性的提出各中低产田以及土壤改良的对策与建议。
In order to grasp the fertility of cultivated land and the distribution of middle and low yield field in Funan County and to study the corresponding improvement and utilization measures, based on the data textual data of the second soil survey and soil testing and fertilization in Funan County, in the field of geographic information system and computer technology Support, the production potential of cultivated land in Funan County is divided, and on this basis, according to the “Classification and Improvement of Medium and Low Yield Fields National Technical Specifications” (NY / T310-1996) and the actual situation of Funan County, Funan County, low-middle-income Field type of secondary system division. The results showed that the fertility of cultivated land in Funan County can be divided into five grades, and on this basis, the middle and low-yielding fields were divided into three types, that is, the arid irrigation type, the waterlogging type and the waterlogged drainage type. And put forward some countermeasures and suggestions for the improvement of middle and low yield fields and soil.
