摘　　要：为探究郴州安仁烟区烟稻轮作制下,烟稻栽培的最优配套技术,采用烤烟品种‘云烟87’与晚稻杂交品种‘ C 两优4488 ’为试验材料,研究不同终采期对上部烟叶质量的影响,以及对配套的晚稻品种播种期、移栽期、安全齐穗期及产量的影响.结果表明, 月2 4 日采收的上部烟叶的外观质量和主要化学成分指标最优,上中等烟比率为91.4 % .从配套的晚稻播插期来看,6 月9 - 2 3 日播种,7 月12 - 2 6 日移栽,晚稻C 两优4488均能安全齐穗,产量则以6 月1 6 日播种、7 月1 9 日移栽最高.从烟稻产量和质量综合考虑,建议在安仁烟区,上部烟叶的终采期可推迟到7 月2 0 日以后,晚稻的播种期应在6 月中旬,晚稻的移栽期以不超过7 月2 5 日为宜.这样既能提高上部烟叶质量,又能确保晚稻安全齐穗,实现烟农经济效益最佳.In order to exploring the optimal matching cultivation technology of flue-cured tobacco and late rice on the tobacco-rice rotation system in Chenzhou tobacco area in Anren county,flue-cured tobacco variety‘Yunyan 87'and late hybrid rice combination ‘C liangyou 4488'were used as materials to study the effect of different final harvest date on the quality of tobacco upper leaves,and the effect on the date of late rice sowing,transplanting,security of full panicle stage and yield. The results showed that: the best quality and chemical composition of upper leaves of flue-cured tobacco occurred at harvest date of July 24 th,and the proportion of medium and superior of flue-cured tobacco leaves is 91. 4%. In Anren county,late rice sowing date should be June 9th to 23 rd,and transplanting date should be July 12 thto 26th,the full panicle stage of late rice will be secured. The highest yield could be got when the seed sowed at June 16 th and transplanted at July19 th. When the yield and quality of both flue-cured tobacco and late rice were taken into consideration for Anren county,the final harvest dates of tobacco upper leaves should be postponed after July 20th; and late rice sow date should be in the middle of June; and late rice transplant date should be no later than July 25 th. The quality of tobacco upper leaves,full panicle security of late rice,economical benefit of both flue-cured tobacco and late rice will be improved.
