Effects of Plate Airing on Floating Nursery of Tobacco in High Altitude Area
摘要
Abstract
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.关键词
