不同施氯量對烤煙氯含量和產(chǎn)質(zhì)量的影響
Effects of Chlorine Rates on Chlorine Content, Yield, and Quality

摘要: 研究了不同施氯量對煙株氯含量、積累量及烤后煙葉產(chǎn)質(zhì)量的影響,。結(jié)果表明,，隨施氯量上升，煙株氯含量和積累量均表現(xiàn)為顯著上升的趨勢,，整株氯含量和積累量與施氯量呈極顯著的正相關(guān),。施氯量從0 kg/hm2提高到48 kg/hm2時(shí),，上部葉中的氯明顯增加；但施氯量進(jìn)一步增加到96 kg/hm2時(shí),，中部葉和下部葉中的氯增加較為顯著,；莖和根中的氯隨施氯量增加而表現(xiàn)出下降的趨勢。施氯量在24 kg/hm2時(shí),，烤后煙葉產(chǎn)質(zhì)量較好,，化學(xué)成分較為協(xié)調(diào)，不施氯或施氯太高均不利于煙葉質(zhì)量的提高,。Abstract: Chlorine content, distribution and accumulation, yield and quality of flue-cured tobacco were influenced remarkably by different amount of chlorine applied. Chlorine content and accumulation increased remarkably as increasing chlorine rate. There was a linear relationship between chlorine rate and chlorine content or accumulation. Chlorine distribution in upper leaves increased evidently as increasing the amount of applied chlorine from 0 kg/hm2 to 48 kg/hm2; and distribution in middle and lower leaves increased remarkably as increasing the amount of applied chlorine to 96 kg/hm2; chlorine distribution in stem and roots had degressive trend as decreasing the amount of applied chlorine. Yield, quality and chemical composition were the best with 24 kg/hm2 of chlorine applied; no chlorine applied or applied chlorine more than 24 kg/hm2 had worse effects on yield and quality.
