| 摘 要： | 目的]探讨种植密度对烤烟K326生长发育和经济性状的影响,为永川烟草的田间栽培提供参考。方法]测定并比较不同种植密度处理下烤烟农艺性状、叶绿素含量和经济性状。结果]各处理农艺性状指标差异不显著。不同处理相对叶绿素含量差异显著,不同时期的相对叶绿素含量以16 500和18 180株/hm2密度处理较高,不同处理均表现为打顶期旺长期成熟期。22 725株/hm2密度处理各项经济性状指标较差,18 180株/hm2密度处理各项经济性状指标较高。结论]总体比较,以种植密度18 180株/hm2较适宜烤烟生长。

| 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. |
