不同移栽期对恩施烤烟产量和质量的影响
Effects of Transplanting Time on Yield and Quality of Flue-cured Tobacco in Enshi

摘要: 为了明确移栽期对恩施烤烟产量和质量的影响,在湖北恩施的宣恩、利川和巴东3个县（市）开展了烤烟移栽期试验研究。结果表明,依据当年气候条件特点,以宣恩试验点为代表的相同海拔区域,移栽期较常规移栽期适当提前可以提高烟叶的产量和品质,4月29日移栽的处理烟株田间长势、烤后烟叶产量、化学成分协调性等均优于5月6日,5月13日和20日的处理,建议宣恩试验点烟苗在4月底5月初移栽；以利川试验点为代表的相同海拔区域,各处理烟叶化学成分差异显著,5月13日和20日移栽的烟株在各方面表现较好,建议在5月中旬移栽以获得优质烟叶；以巴东试验点为代表的相同海拔区域,5月9日移栽的烟株比提前或推迟移栽的经济效益高,烟叶内在化学成分协调性比较好,成熟期雨量较少,建议在5月中上旬移栽以保证当地气候资源的有效利用,提高烟叶产质量。Abstract: To study the effects of transplanting time on yield and quality of flue-cured tobacco, we designed transplanting test in Xuanen, Lichuan and Badong. The results showed that: in Xuanen, Shifting the transplanting date to earlier date properly could improve the yield and quality, e,g. in the end of April or beginning of May; in Lichuan there was significant difference among the chemical components of the four treatments. The treatment three and four were better than the other treatments, transplanted tobacco in middle to late May was appropriate; In Badong, the chemical components of tobacco which transplanted on May 9th were more harmonious than on earlier or later dates. Therefore, we suggest the best transplanting date should be on early or middle May.
