| 摘 要： | 探讨了大田小麦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MapGIS的网格划分确定，分析数据采用统计分析软件DPS进行系统聚类，获取了龙口市北马镇小麦田的土壤养分分类及其空间分布信息．根据聚类结果，可把北马镇麦田分为5类进行养分管理，按照平衡施肥的原理，计算出各类小麦田的施肥量．在地理信息系统软件MapGIS的支持下，得出了北马镇麦田土壤养分分类图，并参照各类的施肥量实施区域化养分管理，为当地小麦种植施肥提供依据。

| Abstract: | A study was conducted on the method of regionalized soil nutrient administration in the wheat field. The sites of sampling for field soil were decided by grid cell partition of maps grounded on MapGIS. Data of soil nutrients and soil organism were analyzed by DPS cluster analysis, thus the information of soil nutrient classifications and spatial distribution was obtained. There are 5 regions for wheat soil in Beima town and each of them had different fertilization plan calculated by the theory of balanced fertilization. With the support of MapGIS soil nutrient classifications map was achieved, and by the fertilization amount of each region regionalized soil nutrient administration was carried out ,which will supply the foundation for local wheat plantation and fertilization. |
