【摘要】：以新疆兵团农七师 12 5团为例 ,探讨建立了乡镇、团场级土壤肥力信息管理和棉花施肥推荐支持决策系统。通过应用地理信息系统 (GIS)、数学模型等方法建立了土壤肥力评价模型和评价体系 ,结合肥料试验建立了棉花施肥推荐支持决策系统。系统具有生成乡镇、团场地理信息土壤肥力分布图、分析土壤肥力资源、提供棉花施肥咨询与配方推荐等功能。系统应用的结果表明 ,12 5团土壤肥力大多处于中等水平 ,高、中、低肥力土壤的面积所占比例分别为 30 .5 %、4 1.5 %和 2 8.0 % ;2 0 0 0年推广 2 .87万ha,每公顷节约化肥投入成本 114元 ,增产皮棉 12 3kg ,合计节本、增效 15 84万元
[Abstract]:Taking 125 regiment of Xinjiang bingtuan seventh division as an example, this paper discusses the establishment of information management system of soil fertility and recommendation and decision support system of cotton fertilization in villages and towns, and through the application of geographic information system (GIS). The evaluation model and evaluation system of soil fertility were established by mathematical model, and the decision system of recommendation and support for cotton fertilization was established in combination with fertilizer experiment. The system has the ability to generate the distribution map of soil fertility in villages and towns and farms with geographical information. The analysis of soil fertility resources and the function of cotton fertilization consultation and formula recommendation. The results of systematic application showed that the soil fertility of No. 125 regiment was mostly in medium level, high and medium. The proportion of low fertility soil area was 30. 5% and 28. 0%, respectively. In 00, 2. 870,000 ha was popularized, the cost of chemical fertilizer was saved by 114 yuan per hectare, and the production of lint was increased by 123kg. The total cost saving and efficiency increase were 15.84 million yuan
