摘　　要：为探讨龙陵县低热河谷流域冬春烟适宜的覆膜移栽方式,通过分析龙陵县低热河谷流域气象因子,采用大田试验并控制覆膜的方法,以红花大金元为试验对象,研究不同覆膜方式移栽对冬春烟生长及产质量的影响。试验结果表明：在龙陵县低热河谷流域冬春烟上采用膜下移栽方式有利于避开1～2月低温对烟株的影响,促进烟株早生快发,降低田间烟株病毒病、青枯病、气候斑的发病率;增加烤烟的产质量,其中上等烟比例提高5.43～6.56个百分点,均价提高3.36～8.20元/kg,产量提高207～645 kg/hm产值提高13307.7～33193.3元/hm主要化学成分指标影响较小。In order to investigate the low valley basin in Longling County tobacco suitable mulching transplanting methods, through the analysis of meteorological factors in Longling County low valley basin, with methods of field test and control film. honghua dajinyuan as test object, studied the influence of different film mulching transplanting on winter spring tobacco’s growth and yield and quality. Test results show that transplanting methods under film can avoid 1-2 month low effect on tobacco in the low valley basin of Longling County and promote the tobacco sooner, reducing the incidence of tobacco virus diseases, bacterial wilt in field,climate spot rate;increasing the yield and quality of flue-cured tobacco, which raises the proportion of 5.43-6.56 percentage points, fold increases 3.36-8.20yuan/kg, yield increases 207-645 kg/hm2, output 13307.7-33193.3 yuan/hm2;index of main chemical composition influence is small.
