摘要 为研究高海拔地区晾盘处理对烟苗的影响,2011年于泸州市对比了晾盘和不晾盘2种条件下,烟苗生育期、盘面温度、烟苗农艺性状等指标。结果表明,10:00和16:00记录期内晾盘处理平均盘面温度均比不晾盘高0.99~1.67℃,说明晾盘处理对盘面温度提升效果较为明显;晾盘处理的成苗期比不晾盘提前5 d;成苗时晾盘处理烟苗株高、茎围、单株鲜重、干重、干鲜比及根系干重、茎叶干重、根冠比、根系干鲜比、一级侧根数目均较不晾盘有所增加,其中烟株鲜重及干重、根系干重及根系干鲜比增加最为明显。 In order to research the effects of airing-floating nursery tray on tobacco seedlings in high altitude area, growth period, floating nursery tray temperature and agronomic characteristics of tobacco seedlings were compared with untreated tobacco seedlings in Luzhou City in 2011.Results showed that floating nursery tray temperature was 0.99-1.67 ~C higher than untreated tobacco seedlings at 10:00 and 16:00 in recording period;Airing- floating nursery tray treatment was 5 days in advance compared with untreated tobacco seedlings;plant height,plant diameter, fresh weight,dry weight, fresh and dried over, root dry weight, dry weight of leaf and stalk, ratio of root and shoot, ratio of root fresh and dried over, the number of lateral roots were increased than untreated tobacco seedlings ,and fresh weight ,dry weight,root dry weight,ratio of root fresh and dried increased most bemarkedly.
