| 摘 要： | 提出了大豆田恶性杂草—苣荬菜的综合防除技术体系：１）降低大豆在整个轮作体系中的比例，将苣荬菜消灭于禾谷类作物四；２）深翻抑制芽根的萌发；３）大豆前茬作物收获后秋季茎叶处理２．４－Ｄ丁酯，最佳用药量为０．８１～１．３５ｋｇ／ｈｍ２，最佳施药时期为１０月５～１０日；４）作为挽救措施可在大豆播后苗前施２．４—Ｄ丁酯，用药量为０．７２ｋｇ／ｈｍ２，并可与乙草胺、赛克津等常规大豆田除草剂混用．

| Abstract: | A Comprehensive Controlllng system of perennial sowthistle in the soybean field was developed.It includes (1) decreasing the proportion of soybean planting and killing the weed in the cereal crops field during the crop rotation;(2) inhibitting the weed emergence from root buds by deep ploughing; (3)0.81-1.35kg/hm2 2.4 D foliar spraying in fall,of October 5～10, if the following crop is soybean next year;(4) as a remedial practice,treating with 0.72kg/hm2 2,4 D mixed,if necessary;with metribuzine and Acetochlor before soybean seedling. |
