基于GIS的山地村域水稻推荐施肥量研究
Study on Recommend Fertilization Dosage of Rice at Village-region in Mountainous Area Based on GIS
摘要
Abstract
In order to explore rational fertilization of rice at village-region in mountainous area, the'3414' fertilizer experiment was carried out in Wuzhang Group, Wenxing Village, Jiuzhou Town, Xixiu District, Anshun City, Guizhou Provincein in 2014-2016. The fertilization model is set based on the experiment data from 11 different testing points in 2014-2016 by regression analysis. The dis-tribution maps of each soil available nutrient content (SANC) were created respectively by spacial interpolation analysis, the data of SANC from 24 random sampling points at the testing field through ArcGIS software, and predicted the SANC of all Wuzhang Group's fields. So we could give suitable fertilization amounts for the fields according to the SANC calculated by the fertilization model based on the soil fertility.关键词
