| 摘 要： | 通过对黔东南州海拔500m以下宜烟区域近年气象资料分析与2009-2011年烟稻两熟试验示范.结果表明：（1）黔东南州500m海拔以下宜烟区域4月-10月热量充沛,可以满足烟稻两熟所需热量;（2）前茬烤烟最佳移栽期为4月5日前,后茬水稻最佳移栽期为7月30日前;可以使烤烟成熟期及水稻抽穗扬花期等关键时期处于适宜范围;（3）纯收益分别烤烟单作、水稻单作增加46.4％和84.94％以上.

| Abstract: | Through analysis of regional meteorological data from appropriate tabacco - grown areas above sea level 500 m in Qiandongnan within 2009--2011 years and tabacco -- rice double cropping demonstration. The results showed that, heat of ap- propriate tahacco - grown areas above 500 m in Qiandongnan was abundant in April--October ,which could meet the need of tobacco and rice double cropping. The transplanting stage of flue--cured tobacco before April 5, and that of the rice before July 30, the flue--cured tobacco maturity and rice flowering and other key period could meet in heat suitable range. Net income could increase 46. 4 Hand 84. 94; than only by flue--cured tobacco monoculture and the rice monoeulture, respectively. |
