4个晒烟品种在广昌县的种植表现

为筛选适合广昌县种植的优良、高抗晒烟品种,以赤水铁赤烟、驿前铁赤烟、杨溪木勺烟和头陂柳叶烟4个晒烟品种为材料,采用田间试验对其在广昌县种植的大田生育期、农艺性状、发病率、经济性状、化学成分及感官质量进行观察评价。结果表明:赤水铁赤烟的大田生育期最长,为120d;驿前铁赤烟其次,为119d;杨溪木勺烟最短,为114d。赤水铁赤烟的农艺性状、经济性状和产质量均优于另外3个品种,且对花叶病的抗性较强;驿前铁赤烟对赤星病的抗性最强,其他综合性状仅次于赤水铁赤烟;而杨溪木勺烟和头陂柳叶烟的综合表现均较差。赤水铁赤烟和驿前铁赤烟可在当地作为优良晒烟品种进行大面积推广应用,杨溪木勺烟和头陂柳叶烟建议作为晒烟种质资源材料利用或改良后再进行试种观察。

Planting Performance of Four Sun-cured Tobacco Cultivars in Guangchang County

In order to screen out the improved sun cured tobacco which is suited for growing and high resistance in Guangchang County,taking cultivars of Tiechi in Yiqian,Mushao in Yangxi,Tiechi in Chishui,Liuye in Toupo as test materials,the authors studied field growth period,agronomic traits,incidence of disease,economic trait,chemical composition and sensory quality of four sun-cured cultivars in Guangchang County.Results:Tiechi in Chishui and Yiqian had the longest growth period(120 d) and second longest growth period (119 d),respectively,while Mushao in Yangxi had the shortest growth period(114 d).Tiechi in Chishui had a longer growth period,agronomic traits,main economic trait and product quality were better than the other three varieties,and it had good disease resistance for mosaic disease.Tiechi in Yiqian had the best disease resistance for brown spot,other characters are only inferior to Tiechi in Chishui.The others were not good in general.As a whole,the species of Tiechi in Yiqian and Chishui could be widely promoted as find sun-cured varieties in the local area,and others were suggested as a test for the use or improvement of resources.
