Abstract
[Objective] To study the effects of planting density on the growth and economic characteristics of flue-cured tobacco K326.[Method] The agronomic characters,chlorophyll content and economic characteristics of flue-cured tobacco were compared among treatments of different planting densities.[Result] Research results showed that the differences of agronomic traits were not significant between treatments.Relative chlorophyll content showed significant differences;and the relative chlorophyll contents of 16 500 plants/hm2 and 18 180 plants/hm2 were relatively high in different periods.Chlorophyll contents in different treatments were all in the order of topping stage ＞ vigorous growing period ＞ mature stage.The economic indicators in 22 725 plants/hm2 treatment were relatively poor,those in 18 180 plants/hm2 treatment were relatively high.[Conclusion] Planting density of 18 180 plants/hm2 is suitable for the growth of flue-cured tobacco.关键词
