摘　　要：[目的]研究了烟薯套作模式,有效提高烟农纯收益,促进当地烤烟发展。[方法]采用完全随机设计,研究烟薯套作与烤烟单作对气候资源利用率、烟株农艺性状、烟叶化学成分、土壤含水量、农田经济效益的影响。[结果]较烤烟单作而言,烟薯套作模式可分别提高活动积温(≥10℃)、降雨、日照利用率29个百分点、16个百分点和24个百分点;可显著降低烟叶烟碱6.5%,提高垄沟土壤含水量;可增加纯收益9 571.5元/hm2。[结论]烟薯套作模式可成为当地烟农增收的新途径。[ Objective ] Relay-intercropping of tobacco with tuber pattern was studied to improve the tobacco farmers net benefits and promote the development of local flue-cured tobacco. [ Method] A field experiment was conducted to study the effect of relay-intercropping of tobacco with tuber pattern on the utilization of climatic resource, tobacco agronomy character, etc. by using randomized controlled trial. [ Result ] The results showed that compared with flue-cured tobacco monoeulture, the utilization of accumulated temperature（ ≥ 10 ℃ ） , rainfall and sunshine were increased respectively by 29percent points, 16percent points and 24percent points on relay-intercropping of tobacco with tuber pattern; nicotine content was significantly decreased by 6.5 % , soil water content in furrow was improved;the net income increased 9 571.5yuan/hm^2. [ Conclusion] Relay-intereropping of tobacco with tuber pattern can be a new way to improve income of tobacco farmers.
