摘　　要：四川丘陵区地处成都平原向盆周山区的过渡地带,不同区域受自然生态环境,人类经济活动,耕作习惯等因素影响较大,病、虫、草害的发生特点与规律差异明显。为提供四川丘陵区农作物病、虫、草害的防治重点,提高防治科学性和准确性,本研究通过实地调查数据结合四川丘陵区农业经济和农业发展现状、地理区位概况等大量资料,综合分析了小麦、玉米、油菜、蔬菜、马铃薯、大豆等作物主要发生的病虫害种类、危害程度和危害趋势。综合数据表明各类作物病虫草害在四川丘陵区各区域均有发生,不同亚区相同作物的病虫草害发生种类上差异不大,但其发生时间和危害程度差异明显。文章综述了四川丘陵区主要粮经油料作物的病虫草害发生特点及规律,分析了病虫害的发生趋势,提出了四川丘陵区农作物病虫害防治的可行性策略。Sichuan hilly area is located in the transition zone between the Chengdu Plain and the basin-mountain mountainous area,various factors,such as natural ecological environment,human economic activities and farming habits,caused different types of diseases,pests and weeds damage in Sichuan agricultural regions.In order to provide control emphasis and improve its scientificity and accuracy for crop diseases,pests and grass pests control,we combines field investigation data with a large amount of information such as the status quo,geographical location of agricultural economic and agricultural development in Sichuan province.A comprehensive analysis of the main types of pests and diseases,hazard degree and hazard trend of wheat,corn,rapeseed,vegetables,potatoes,soybeans and other crops have been made.The results showed that there was no significant difference in species on the same crops in different sub-regions all kinds of crop diseases,insect pests and weeds occurred in different hilly subregions of Sichuan province,however,the degree of damage and the occurrence time were significantly different.Collectiely,the occurrence characteristics and trend of diseases,pests and weeds on major crops in Sichuan hilly area were summarized in this study.It also puts forward the feasible control strategies in Sichuan hilly area.
