为研究不同水稻病害杀菌剂田间药效试验区域布局,中国农业大学农学与生物技术学院和农业部农药检定所研究人员合作,统计分析了2011至2013年全国水稻种植面积、水稻生产中8种主要病害的发生面积并将其按照大小划分为4个等级,结合GIS软件绘制水稻种植与病害发生分布的地理信息矢量图,以此研判杀菌剂防治水稻主要病害田间药效试验区域布局的省区最佳选择。 In order to study the regional distribution of field efficacy test of different fungicides for rice diseases, researchers from Agricultural and Biotechnology College of China Agricultural University and Pesticide Bureau of Ministry of Agriculture cooperated with each other to statistically analyze the national main rice planting areas and the eight main types of rice production in 2011-2013 The area of ​​disease occurrence was divided into 4 grades according to the size. GIS software was used to draw the vector map of the geographical information of the distribution of rice planting and disease, so as to determine the provinces and autonomous regions of the field efficacy test of fungicide for controlling the main diseases of rice Good choice.
