摘要
在浙江省开化县新造林地进行了化学除草剂类型、施药量、打药次数、打药时间对控制五节芒效果试验.结果表明：化学除草剂可以有效控制五节芒,但其效果受施药量、打药时间和打药次数的影响.当五节芒新生茎叶高度达40 cm左右,喷施草甘膦2 - 3 次,喷施量11.25 L/hm2,或喷洒1 - 2 次森泰,喷洒量12 L/hm2,均可以有效控制五节芒;采用化学除草剂比纯人工治除五节芒成本降低12% - 28%.
Orthogonal experiments were conducted on control Miscanthus floridulus in new plantation （different tree species and density） withdifferent herbicides, dosages, frequencies, spraying times in 2013 in Kaihua, Zhejiang province. The results showed that herbicides could effectivelycontrol M. floridulus, but was affected by the dosage, frequencies, spraying time. The experiment resulted that it had good effect of spraying 2-3 timesof 11.25 L/hm2 glyphosate, or 1-2 times of 12 L /hm2 hexazinone on M. floridulus with height of 40cm. The cost of chemical control to M. floridulusreduced 12-28% compared with that of labor.
