基于GIS的桓仁满族自治县耕地配肥系统设计

Design of Farmland Fertilizer System in Huanren Manchu Autonomous County Based on the GIS

介绍了基于GIS(技术设计的耕地配肥系统)。结合县级耕地土壤采样检测数据,利用地统计学方法,获得地块的目标产量、有机质、p H、碱解氮等养分值;再利用平衡施肥原理,采用数据库自动匹配技术,计算出地块的施肥量,给出施肥建议。

In this paper,the author introduces the design technology based on GIS （Geographic Information System ） for farmland fertilizer system at the begin,then puts forward the suggestion for fertilizer in this area according to the following process：1. combing the testing data of soil sample in this area and using geostatistical analysis method to get land’s target yield、organic matter、pH、alkaline hydrolysis N nutrient value,etc. ; 2. using the principle of balanced fertilization to figure out the rate of fertilizer application with the database matching technology.
