摘要
经大面积、多点、多年的试验结果表明 ,烟稻轮作烟地用都尔或大惠利进行化学除草 ,其作用是多方面的 ,不仅除草效果比传统的人工中耕除草好 ,节省除草用工 ,而且使烟株根系发达、生长健壮 ,有利于烟地水土保持 ,减少肥料的消耗和流失 ,减少烟草病虫害的发生和危害 ,增加株高和叶片面积 ,提高烟叶品质和产量 ,投入与产出比为 32倍。
According to tests of large area demonstration and multi-site in tobacco-rice rotation fields during 1993～1996,the results showed that action of chemical weeding was on many ways,the effect of chemical weeding being better than artificial intertillage weeding,keeping normal growth of tobacco root system,favouring of water and soil conservation,reducing manure depletion and shifting and the harm of disease and insect pests,saving on weeding work-days,extenuating labour intension,improving tobacco agronomic and economic characters and increasing the ratio of invest/out(1∶32).Chemical weeding in tobacco-rice rotation fields get possession of obvious actions on economical,sociologcal and ecological benefit.
