摘要
探讨了基于系统聚类分析对大田小麦进行区域化土壤养分管理的方法。田间土壤采样点通过室内图件的网格划分,化验分析数据采用系统聚类,获取了龙口市北马镇小麦田的土壤养分分类,并将系统聚类分析的结果与养分分级的结果相比较。按照因缺补缺的原则推荐施肥,为当地小麦种植施肥提供理论依据。
The method of regional soil nutrient management was studied based on systematic cluster analysis. The sampling sites for field soil are decided by indoor grid partition of maps. Data of soil nutrients and soil organism were analyzed by systematic cluster analysis and the information of soil nutrient classifications was obtained, and the conclusions of systematic cluster analysis with soil nutrient grades are compared, so that reasonable amount of fertilizer could be recommended, which supplies theoretical foundations for local wheat production.
