【摘要】 通过对2002至2004年湖南南部稻田土植烟区域土壤的成土母质调查,经检测分析表明,采集的土壤样品416个,以石灰岩发育的土壤为主,占82.9%;土壤pH值分布状况为:416个样品中以pH值在7.6～8.0范围的土壤为主,占62.5%。说明湖南南部烟稻水旱轮作区植烟土壤主要集中在石灰岩发育的pH值在7.6～8.0范围的土壤。在不同pH值土壤种植烤烟试验结果表明,烟叶的外观质量、内在化学成分、感观评吸质量以及烟气成分没有差异或没有明显差异,说明湖南南部稻田土烟稻水旱轮作,土壤pH值在5.5～8.0间,均可种植优质烤烟,且烟叶质量上乘,是典型的浓香型优质烟区。更多还原

【Abstract】 The primary soil of Hunan’s southern paddy field is investigated and analyzed in 2002 to 2004.416 soil specimen are collected.Soil mainly developed from limestone counted for 82.9%.The pH of soil distributed as follow:Soil with pH between 7.6 and 8.0 counted for 62.5% in 416 soil specimen.The results showed tobacco-cropping soil in tobacco-rice watery-dry rotation area of Hunan’s southern part was mainly the soil developed from limestone with pH between 7.6 and 8.0.The results of experiments carried in tobacco cropping soil with different pH showed that there were no difference or significant difference among tobacco appearance quality、interior chemical contents、sensual smoking quality and tobacco gas contents.It showed soil with pH between 5.5-8.0 in tobacco-rice watery-dry rotation area of Hunan’s southern part was generally suitable for cropping high quality tobacco and quality of the tobacco was good where is a typical high quality tobacco area.更多还原
