Effect Of Transplanting Under The Film On Yield And Quality Of Flue-cured Tobacco

In order to solve the problem that flue-cured tobacco production encounters low temperature, realize the promotion of quality and quantity and improve the activeness of tobacco grower in Zhaotong Area, the research of seedlings transplanting technology under flue-cured tobacco film was developed and the field experiment was enforced in several flue-cured tobacco production counties of the city during 2012 to 2013. Compared with influences of different hardening-seedling methods, transplanting seasons, fertilization methods, transplanting seedling ages and film covering methods to quality and quantity of flue-cured tobacco, technical combination of seedling transplanting fitting in Zhaotong Area was chose. Main research results are as follwes:1. Different hardening-seedling methods of seedling transplanting influence the growth and economic traits of flue-cured tobacco. Turning on the water to refine seedlings for 5 days before transplanting can improve the quality and quantity of flue-cured tobacco.2. Different transplanting dates influence the economic traits of flue-cured tobacco. The period between 31st, March to 5th, April is fittest for seedling transplanting in Zhaotong Area. The period between 26th, March to 20th, April is fitter for local seedling transplanting in Zhaotong Area. Seedling transplanting after 20th, April has weak growth situation, low rate of survival and short growth time under the film, which is not fit for local application.3. Different transplanting seasons influence the economic traits of flue-cured tobacco. Disposable annular fertilization after open channel transplanting and transplanting after disposable bog fertilization are the fittest for Zhaotong Area.4. Different transplanting seedling ages and film covering methods influence the growth and economic traits of flue-cured tobacco. Seedling transplanting under the film of four leaves and one heart has good growth situation and high quality and quantity. It can be mature ahead of a season compared to normal transplanting.
