| 摘 要： | 1989～1991年经室内测定和田间小区及示范试验,发现芽前土壤处理剂大惠利和敌草胺每公顷施用有效成分750～1125g,都尔1080～1290g,对烟草地杂草特别是对单子叶杂草防效好;芽后茎叶处理剂羞草能、禾草克、精稳杀得等每公顷施用有效成份90～120g,对烟地3～5叶期禾本科杂草超高效.除草剂的药效与整地精细度、老杂草清除情况,整地后施药的迟早、喷药的均匀度等因素有关,以施药时及施药后保持土表湿润和均匀的药剂层至关重要、对烟苗的安全性与施药方式密切相关.本文还对烟地化学除草的经济效益进行了分析.

| Abstract: | During 1988 to 1991, 10 kinds of herbicide were used in the tobacco fields of about 153 ha. so as to have their effects tested. It was found that application of pre-emergence herbicide, Devrinol (750 to 1125 g, a.i./ha,) and Daul (1125 to 1290 g.a.i./ha) for soil treatment was highly effective against annual monocotyledonous and certain annual broadleafed weeds and the Use of post-emergence herbicide, Gallant, Nc 302, Oncide-p (90 to 120g.a.i./ha.) was highly effective against agramineae weeds in 3 to 5 leaves period. The effect of the three pre-emergence herbicides was affected by soil conditions; clearing-out of old weeds or not; spraying early or late after cultivation and especially the soil moisture and the uniformity of fertilizer application. The safety relates closely to the methods of apllication. |
