Effects of Shading Condition on Growth, Yield and Quality of Flue-cured Tobacco(Nicotiana tabacum L.)
摘要
Abstract
[Objective] The purpose was to study the effects of different shading condition on growth, yield and quality of flue-cured tobacco, and confirm the relationship between illumination condition and flue-cured tobacco growth. [ Method ] K326 was used as the tested tobacco variety. Black shading-nets usual applied in production was used to conduct shading treatment to flue-cured tobacco at resettling stage, thereinto, in treatment A and B its mesh density was 60% and 90% resp. , CK was no shading. There were 120 plants in treatment A or B resp. With 3 repeats, 80 plants in CK with no repeat. There were 2 protective rows with north-south arrangement around each plot, the distance between 2 rows and the individual spacing was 120 and 50 cm resp. . [ Result] The results showed that shading went against overground part of dry matter content and phenologic development of flue-cured tobacco. Treatment of 60% shading contributed to increase flue-cured tobacco' s leaf length, leaf area index, plant height, total leaf number, angle between leaf and stalk, underground part of ratio of dry weight to fresh weight, treatment of 90% shading made flue-cured tobacco' s section spacing significantly increase. With the increase of shading, the yield, quality, average price, proportion of high and middle grades of cured tobacco leaf obviously descended. Moreover, the effects of different shading treatment on microclimate in field was relatively notable. [ Conclusion ] The study provides a theoretical basis for flue-cured tobacco' s adaptability analysis and planting division.关键词
