摘　　要：近年来,受国家政策及市场调控影响,大豆价格高位运行,农户种植热情高涨,而病虫草害是制约大豆产量的主要因素。富锦市大豆栽培中,大豆根腐病、大豆蚜虫、大豆食叶性害虫、大豆灰斑病、大豆霜霉病、大豆食心虫等病虫害,以及刺菜、红根苋菜、鸭趾草等抗性杂草多发,科学合理地使用化学农药是防治大豆病虫害的重中之重。从种子处理、开花结荚病害防治、大豆食心虫防除、封闭加茎叶两次用药除草,综合防治大豆病虫草害进行技术研究,达到了绿色、减量、高效,增产增收,保护环境目的。In recent years,the high price of soybean is affected by the national policy and market regulation,and the enthusiasm of farmers for planting is high,while the diseases,pests and weeds are the main factors restricting the yield of soybean.In soybean cultivation in Fujin City,soybean root rot,soybean aphids,soybean leaf-eating pests,soybean gray spot,soybean downy mildew,soybean food worms and resistant weeds such as prickly cabbage,red root amaranth and duck toe are common,scientific and rational use of chemical pesticides is the most important.This experiment studied the rational distribution of chemical pesticides,the integrated control of soybean diseases,pests and weeds by seed treatment,control of flowering and podding diseases,control of soybean heartworm,herbicides and herbicides were studied to increase production and income and protect the environment.
