摘　　要：为解决南方烟区育苗时温度过低影响烟苗后期生长的问题,进行了在育苗池底部铺设有氧发酵材料(稻草秸秆、稻草秸秆+猪粪、稻草秸秆+花生麸)的增温育苗试验,对育苗池温度、烟苗生长状况和移栽后的大田农艺性状、干物质积累及产量产值等经济性状进行了测定。结果表明,有氧发酵增温育苗,尤其是稻草秸秆+花生麸处理,可以有效提高育苗池温度(1℃以上),使苗龄缩短13 d,其壮苗率达95%;有氧发酵增温育苗移栽后株高、茎围、根长等都显著大于对照(常规浅水育苗),节距则小于对照,因而叶片数更多;地上部和地下部的干物质积累与对照的差异显著,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 southern tobacco planting region,aerobic fermentation materials were paved on the bottom of nutrition pool,then the water temperature,growth status of tobacco and agronomic characters,accumulation of dry matter after transplanting and economic traits such as yield and output value were determined.Results showed that laying aerobic fermentation materials especially peanut bran under the seedling-bed could increase the temperature of nutrition pool,shorten seedling growing period by 13 days,and the ratio of strong seedling reached 95%.After transplanting,the stem length,stem girth and root length were greater but the pitch was less than the control,so there were more leaves.There existed significant difference on accumulation of dry matter include overground and underground between treatment of peanut bran and the control.The yield,output value,ratios of grade A and grade B leaves were better than the control obviously.
