攀西烟区烤烟不同垄作方式对烤烟生理生化和品质的影响

[目的]为了探究不同垄作方式对攀西烟区烤烟品质的影响。[方法]于2016年在攀枝花仁和区平采用大田试验,采用3种不同的垄作方式,分别为一垄双行、宽窄行、常规起垄,研究不同垄作方式对烤烟生育期、农艺性状及生理生化的影响。[结果]与常规起垄方式相比,一垄双行、宽窄行以及平栽烟高起垄栽培方式对烤烟的生育期无影响;3种垄各项生理生化性状均大于常规垄作;宽窄行栽培烟叶化学成分含量及其比例关系优于常规栽培。

Effects of Different Ridge on Physiology, Biochemistry and Quality of Flue-curedTobacco in Panxi Region

[purpose] In order to explore the effects of different ridge on quality of flue-cured tobacco in PanxiRegion.[methods]A field experiment was carried out in the random block design of the flat Town, Renhe District,Panzhihua city. Three treatment groups were set up:A double ridge planting method, wide planting method, andconvent conventional method. [results] It shows that compared with the conventional ridge, ridge and narrow rowcultivation and flat planting tobacco ridging on flue-cured tobacco growth period have no effects, but were beneficialto improve the agronomic traits of flue-cured tobacco; and its physiological and biochemical characteristics can beimproved, the content of chemical components of tobacco leaves under cultivation and its proportion is better thanconventional cultivation. The content of chemical composition and proportion of tobacco leaves in the width werebetter than that of conventional cultivation.
