摘要
Abstract
The growth period ,seedling quality and yield and quality of flue-cured tobacco were studied with Zhongyan 100 at different depths of water level for optimizing the floating system for tobacco seeding .The results showed that ,with the decrease of water level in seeding pool ,every index of tobacco seedling tended toward a favorable direction after little cross-seedling stage ,and dry-wet alternation was the best for tobacco seedling .The dry-wet alternation had no significant difference in emergence stage and rate from conventional floating system for tobacco seeding ,but it was of benefit to root development and the growth vigor .The root development and uniformity were better in seedling formation period .The rates of seedling and strong seedling increased by 1.6 and 2 .4 percent points .Compared with control ,the time of seedling establishment was short-ened by 5 days .And the rate of spiral root ,disease ,and blue green algae occurrence decreased sig-nificantly .The dry-wet alternation method increased the first-class tobacco and average price by 3 .26 percent points and 2 .31 yuan/kg ,and also increased the yield and output value by 187 kg/ha and 9 745 .67 yuan/ha .The way of dry-wet alternation of floating system for tobacco seedling was suggested to be beneficial to the seedling establishment and production value increase after little cross-seedling stage .关键词
