不同增温措施对烟苗生长发育的影响
Effect of Different Temperature-increasing Measures on Growth and Development of Flue-cured Tobacco Seedlings
摘要
Abstract
In order to solve the low-temperature hazards in flue-cured tobacco seedling raising at high altitudes in Shizhu,the effects of different temperature-increasing measures on environmental temperature and the growth and development of flue-cured tobacco seedlings were researched. The results showed that the double-decked awning measure,double-decked awning+pool bottom bedding measure, and germination-accelerating seedling-raising measure could respectively improve average temperature by 0. 84,1. 14,5. 42 ℃ compared with floating system,the seedlings came out 6,7,14 days in advance and the whole growth period shortened by 6,8,12 days. Besides, these temperature-increasing measures improved the quality of seedling to different degrees and promoted tobacco material accumulation. The analysis of different parts of tobacco seedlings demonstrated that the germination-accelerating seedling-raising measure could promote the growth of tobacco parts on the ground,while the double-decked awning+pool bottom bedding measure stimulated the growth of tobacco seedling roots. In production,it is suggested to optimize different measures to increase total effective temperature in order to achieve the ideal effect of seedling cultivation.关键词
