摘要
使用模糊聚类分析的方法,对吉林省榆树市弓棚镇春阳村的黑土土壤进行土壤养分分类的研究,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,实现玉米增产、稳产。
This paper reports that applying the method of fuzzy clustering analysis to the study of the soil nutrient classification, example for the black soil nutrient in Jilin province, and forming the classification model, to confirm the level of soil fertility, in the certain scope we may grasps the principle of corn fertilizing according to the different soil fertility which is one of the important methods realizes increase production or stable production. We have applied this method in production, and the test indicated that the method has the good practical application prospect.
