Evaluation of Climatic Feasibility to Flue-cured Tobacco Transplanted on Different Dates in Pingdingshan Area and Its Similarity to That in Foreign Tobacco-growing Areas
摘要
Abstract
We analyzed the climatic status during flue -cured tobacco growth in Pingdingshan area , evaluated the climatic fea-sibility to flue-cured tobacco transplanted on different dates in this area through quantitatively estimating climatic feasibility index (CFI), and analyzed the similarity of climatic feasibility in this area to that in foreign high -quality tobacco-growing areas.The results indicated that:(1) The field temperature met the requirements of high -quality tobacco leaf to air temperature when the transplanting date was after April 30th.The active accumulated temperature which was greater than or equal to 10 ℃and the sun-shine duration at field tobacco growth stage in 7 transplanting date treatments all were quite propitious to the growth of fine tobacco leaves.The rainfall at the stages of root elongation and vigorous growth in different treatments conformed to the demands of good -quality flue-cured tobacco to moisture , but the rainfall in mature period was relatively more .( 2 ) As the transplanting date was postponed, CFI increased firstly and then declined , and that in the treatment of transplanting on May 5th was the highest.(3) When the tobacco seedlings were transplanted on May 5th, May 15th or May 10th in Pingdingshan area, the climatic feasibility to flue-cured tobacco in this area was very similar to that in America , Brazil and Zimbabwe .关键词
