【摘要】 为更有效地防除烟田杂草 ,在烤烟移栽大田后采用 3种除草膜进行了烟田除草试验。结果表明 ,盖膜后 4 0d绿色除草膜、黑色除草膜和“金都尔”除草膜对单子叶杂草的鲜重防效分别为 90 .6 %、97.2 %和 5 6 .0 % ,对双子叶杂草的鲜重防效分别为 6 4.2 %、6 0 .8%和 2 6 .7%。方差分析表明各处理间差异达极显著水平。盖膜后 10d 30次的地温调查结果表明 ,黑色除草膜、“金都尔”除草膜、绿色除草膜和普通地膜对提高地温均有一定作用 ,但以黑色膜效果最显著更多还原

【Abstract】 To control weed in tobacco field more effectively, field experiments were carried out with 3 types of herbicidal film after flue-cured tobacco transplanting. The results indicated that the control effects of green, black and Kingduer film after 40 days of film covering to monocotyledonous weed (fresh weight) were 90.6%, 97.2% and 56.0%, respectively, and to dicotyledonous weed (fresh weight) were 64.2%, 60.8% and 26.7%, respectively. The variance analysis showed that the difference between different treatments was extremely significant. 30 measurements in 10 days showed that, the average temperature of soil in the depth of 0cm, 5cm, 10cm covering with black herbicidal, Kingduer, green herbicidal, and conventional films were 33.1℃, 28.8℃, 26.8℃ and 24.7℃, respectively.更多还原
