摘要
[目的]为研究植烟土壤环境与烟叶生理指标的关系。[方法]在云南玉溪选取不同地域稻田、麦田、山坡旱地和菜地,对烤烟K326品种进行盆栽试验,研究在相同气候背景和水肥管理条件下,不同土壤对K326生长和光合生理的影响。[结果]生长和生理生化特征的差异可能主要与土壤本身的特性有关,而土壤持水能力对光合气体交换有一定的影响,但其间的差异主要还与不同土壤种植烤烟的气孔调节能力有关。[结论]土壤对烤烟生长和光合生理的影响具有复杂性。
[Objective] The research aimed to study the relationship between tobacco planting soil environment and physiological indices of tobacco.[Method] In Yuxi,Yunnan regional paddy and wheat field,different slope upland and vegetable land were selected.A pot experiment of flue-cured tobacco variety K326 was conducted to study the effects of different soils on the growth and photosynthesis of K326 under the same climate background and the management of water and fertilizer conditions.[Result] The differences in growth and physiological and biochemical characteristics might be related to the characteristics of the soil itself,and soil water holding capacity had a certain influence on photosynthetic gas exchange,but the gap was mainly with regulating ability of different flue-cured tobacco planting soil.[Conclusion] The effects of soil on tobacco growth and photosynthesis were complex.
