水肥耦合对烤烟生理生态特性及产量和品质的影响
The impact of water-fertilizer coupling on growth,development,yield and quality of flue-cured tobacco
摘要
Abstract
[Objective]Tobacco is a cash crop grown in Western Henan Province,central China.This study experimentally investigates the effects of water-fertilizer coupling on its physiological and ecological characteristics,as well as its yield and quality.[Method]A pot experiment was conducted using tobacco variety Qinyan 96 as the model plant.It consisted of three treatments:no fertilization(CK),conventional fertilization used by local farmers(Tl),and drip fertigation(T2,i.e.,water-fertilizer coupling)that delivers soluble or liquid fertilizer into the root zone;each treatment had three replicates.Irrigation was performed at four key growth stages:the transplanting,early vigorous growth,mid vigorous growth,and late vigorous growth stage.During the experiment,we measured physiological-ecological traits including photosynthetic rate,stomatal conductance,chlorophyll content,and dry matter accumulation at different growth stages.After harvest,we measured the yield-related indices(total yield,output value,average price,proportion of premium-grade tobacco leaves)and quality-related indices(protein and starch contents).[Result]Water-fertilizer coupling significantly increased plant height,leaf numbers and leaf area.During leaf growth and development stages,water-fertilizer coupling significantly increased physiological traits such as chlorophyll content,photosynthetic rate,and stomatal conductance.Compared with Tl,T2 increased the proportion of premium-grade tobacco by 19.08％.Compared with CK and T1,T2 increased tobacco yield by 9.11％and 1.92％,respectively,and starch and protein contents in tobacco leaves by up to 0.33％and 2.58％,respectively.[Conclusion]Water-fertilizer coupling effectively improved the physiological and ecological traits of tobacco,thereby increasing its yield and improving its quality.关键词
