摘　　要：彭水县润溪乡是重庆市重要的植烟区,其生态环境非常适合烤烟的生长,烤烟也成为该地区烟农脱贫致富的重要手段之一.润溪乡烤烟生育期内降雨大、持续时间长,烟田杂草种类多、生物量大,严重影响了烤烟的正常生长,同时,人工杂草防除费时费工,进一步限制了当地烟农节流增收,烟田杂草防除成为困扰烟农的一大难题.因此,基于查阅相关文献和报道及笔者的田间调查,本文总结了润溪乡烟田主要杂草种类以及发生规律,提出了烟田杂草系统控制的几项关键技术和要点,以期为该地区的杂草防除以及烟农节流增收提供参考.Runxi is an important tobacco-growing village in Pengshui County of Chongqing,whose ecological environment is favorable for the growth of tobacco plants,and tobacco cultivation has become an important means of poverty elimination of the local farmers.In Runxi,precipitation is usually plentiful and lasts for a long time during the growth period of the tobacco crop,and various weeds with large biomass grow vigorously in the fields,which seriously affects the normal growth of tobacco;and manual weeding is time-consuming and labor-intensive,which makes it more difficult for tobacco growers to increase their income.Based on literature retrieval and the results of their field survey,the authors of this paper give a list of the main species of weeds in tobacco fields of Runxi,discuss the law of their occurrence and propose a few key strategies of tobacco field weed control,so as to provide reference to the tobacco growers in their efforts to prevent and control the weeds in the fields.
