为解决衡阳烟区育苗时温度过低影响烟苗后期生长的问题，进行了育苗池的增温育苗试验，对育苗池温度变化、烟苗生长状况和移栽后的大田农艺性状及产量产值等经济性状进行了测定。结果表明，增温育苗可以有效提高育苗池水体温度(3~8℃)和育苗盘温度(1~5℃)，提高壮苗率；增温培育的烟苗移栽后株高、茎围等都大于不增温培育的烟苗，节距则小于对照，因而叶片数更多，叶面积也要大于对照；产量、产值、上中等烟比例等也明显优于对照。

In order to resolve the influence of low temperature during seedling -breeding on the growth of tobacco in Hengyang tobacco planting region, the paper carried out the trait of raising seedling with temperature increasing in the bot-tom of nutrition pool, and the variation of temperature, growth status of tobacco and agronomic characters, and yield &output value were determined. Results were showed as follow:T1 ( raising seedling with temperature increasing) could in-crease water temperature of nutrition pool (3~8℃), and enhance the ratio of strong seedling. After transplanting, the plant height and stem length were greater than CK ( Non temperature increasing) but the pitch was less than CK, there-fore, there were more leaves in T1, meanwhile, leaf area was also bigger than CK. The yield, output value, the ratios of grade A and grade B leaves were better than CK obviously.
