【摘要】 利用DGPS和GIS空间分析技术,使用Fuzzy聚类分析方法,以吉林省榆树市弓棚镇春阳村的黑土土壤为例,进行土壤养分分类研究,建立分类模型,从而确定土壤肥力水平高低,从宏观上把握一定范围内的不同土壤肥力水平的玉米施肥原则,是实现增产、稳产的重要方法之一。并将其应用于国家"863"计划"玉米精准作业系统研究与应用"项目中,通过实例检验表明,该方法具有良好的应用前景。更多还原

【Abstract】 Using DGPS and GIS spatial analysis technology,applying Fuzzy clustering analysis method,taking the black soil nutrient in Chunyang Village of Gongpeng Town in Yushu City of Jilin Province as an example,the soil nutrient classification was studied to establish the classification model,so as to confirm the level of soil fertility.To grasp the principle of corn fertilizing according to different soil fertility in the certain scope is one of the important methods that realize increases production or stable production.It was applied to National 863 Project of "Corn Precision Task System Research and Application",and the test indicated that the method had good application prospect.更多还原
