摘要： 作者研究了鸭跖草生长发育规律、生物学特性及化学药剂防除，鸭跖草出苗始期为5月上旬，高峰期为5月中下旬，鸭跖草营养生长的高峰期在7月中下旬；出苗的最适深度在5cm以上，20cm无出苗。通过网室筛选试验，对鸭跖草防除效果最好的土壤处理剂为72%都尔和36%农草净；叶面处理为48%广灭灵及24%克阔乐。同时进行了大面积试验示范。

Abstract: The growth and the development of Commelina communis L and its biological characteristics and pesticide prevention and control were studied in this paper. The seeding emergence occurs in the middle of May,while its peak emergence is in the end of the month.The peak period of the vegetative growth is in the end of July. The depth of 5cm from the seeds to the soil surface is favorable for the seed emergence, and no seed emergence was investigated in the depth of 20cm.By mean of sieving exporiment,the Best treatment soil agent of competition Commelina Communis L is 72% Dual and 36% Nongcaojing ,the best treatment agent of leaf surface is 48% Command and 24% Cobra , meanwhile making alargee scale experiments and demonstrations.
