通过设置不同的移栽期,使光温水等气候因子在各烟草生育期重新分配,为分析浓香型风格烟叶形成的气候成因及确定适宜移栽期提供理论依据。结果表明:随着移栽期的后移,总生育期及伸根期、旺长期、成熟期日均温呈逐渐升高的趋势,总生育期、旺长期、成熟期气温日较差则呈逐渐降低的趋势,伸根期气温日较差变化不明显。河南豫中地区4月28日~5月24日移栽处理总生育期日均温为25~26.5℃,活动积温为2249.80~2581.38℃· d,日照时数较足。试验结果表明:烟草总生育期土温日均温逐渐升高,土温日较差、活动积温和有效积温则与移栽期呈显著负相关,以活动积温受气候调节效应的影响最大。推迟移栽期显著降低了烟草总生育期的光照时数和光照强度,对烟草大田总生育期及各生育期大气和土壤温度产生极大影响,以4月21日~5月12日移栽处理的大气温度和土壤温度较为理想。试验结果表明:推迟移栽对烟草大田生长所需降雨量产生极强的调节效应,4月28日和5月5日移栽处理的降雨量分别为428.5和441.2 mm,基本满足优质烟生长需水量。综合不同移栽期的气候调节效应分析可知,以4月28日~5月5日移栽较为适宜,最迟不晚于5月12日。
通過設置不同的移栽期,使光溫水等氣候因子在各煙草生育期重新分配,為分析濃香型風格煙葉形成的氣候成因及確定適宜移栽期提供理論依據。結果錶明:隨著移栽期的後移,總生育期及伸根期、旺長期、成熟期日均溫呈逐漸升高的趨勢,總生育期、旺長期、成熟期氣溫日較差則呈逐漸降低的趨勢,伸根期氣溫日較差變化不明顯。河南豫中地區4月28日~5月24日移栽處理總生育期日均溫為25~26.5℃,活動積溫為2249.80~2581.38℃· d,日照時數較足。試驗結果錶明:煙草總生育期土溫日均溫逐漸升高,土溫日較差、活動積溫和有效積溫則與移栽期呈顯著負相關,以活動積溫受氣候調節效應的影響最大。推遲移栽期顯著降低瞭煙草總生育期的光照時數和光照彊度,對煙草大田總生育期及各生育期大氣和土壤溫度產生極大影響,以4月21日~5月12日移栽處理的大氣溫度和土壤溫度較為理想。試驗結果錶明:推遲移栽對煙草大田生長所需降雨量產生極彊的調節效應,4月28日和5月5日移栽處理的降雨量分彆為428.5和441.2 mm,基本滿足優質煙生長需水量。綜閤不同移栽期的氣候調節效應分析可知,以4月28日~5月5日移栽較為適宜,最遲不晚于5月12日。

By setting different transplanting times , the author redistributed such climatic factors as light , temperature and water in tobacco growth period , so as to provide theoretical basis for analyzing the climate cause of strong -flavor tobacco leaves formation and determining suitable transplanting time .The results showed that:when the transplanting time delayed , the daily mean air tem-perature at the whole growth stage , root-extending stage , vigorous growing stage and mature stage showed increasing trend , and the daily air temperature range at the whole growth stage , vigorous growing stage and mature stage decreased gradually , while the daily air temperature range at the root -extending stage had no obvious changes .When flue-cured tobacco was transplanted in middle Henan province from April 28 to May 24, the daily mean air temperature in the whole growth period was 25.0~26.5℃, the active accumulated air temperature was 2249.80~2581.38 ℃· d, and the sunshine duration was enough .In the whole growth period of tobacco, the daily mean soil temperature gradually increased , the diurnal soil temperature range , the active accumulated soil tem-perature and effective accumulated soil temperature were significantly negatively related to the transplanting time , and the regulatory effect of the climate on the active accumulated soil temperature was maximum .Postponing the transplanting time significantly re-duced the sunlight time and sunlight intensity in the whole tobacco growth period , and had very great influences on the air tempera-ture and soil temperature at different growth stages of tobacco , which were ideal when the tobacco was transplanted from April 21 to May 12.Delaying the transplanting time had a great moderating effect on the required rainfall by tobacco production in the field , and the rainfalls in the treatments of transplanting on April 28 and May 5 were 428.5 and 441.2 mm respectively, which could basically meet the water demand of high -quality tobacco growth .According to the climate moderating effect of different transplanting times , it was more suitable for tobacco to transplant from April 28 to May 5, no later than May 12.
