Control Effect of Plastic Film Cover against Weeds in Rice Field
摘要
Abstract
To understand the control effect of covering rice field with plastic film against the main weeds, the efficacies by covering with plastic film and chemical control were compared. After the rice field was covered with plastic film,the control efficacy based on plants at 10 days before harvest against the common weeds such as Echinochloa crusgalli L. Beau'v, Cyperus rotundus L. , Monochoria pauciflora(Bl. )Kunth. ,Heleocharis plantagineiformis Tang et Wang,and Ludxvigia prostrata Roxb was 90. 0%, 92. 6%, 100%, 83. 3%, 100%, separately increased by 20. 0, 40. 7, 23. 1, 16.6 and 33.4 percentage points than conventional cultivation with chemical weed control. The control efficacy based on weed fresh qualities against the five weeds was all over 85%, increased by 20. 5,33. 4,20. 4,18. 6,10. 8 percentage points than conventional cultivation with chemical 'weed control. In addition, the cultivation mode of covering rice field with plastic film increased rice yield by 22. 7% and economic benefit by 2574 yuan per hectare than conventional cultivation.关键词
