聚碳酶制剂施用方式对烤烟生长发育及产质量的影响
Effects of Application Methods of Poly-carbon Enzyme Formulations on Growth,Development and Quality of Flue-cured Tobacco
摘要
Abstract
To investigate the regulatory effects of polycarbonate enzyme application on dry matter accumulation and distribution in flue-cured tobacco and to optimize its application techniques for coordinated improvement of yield and quality in central Henan tobacco production,this study utilized the flue-cured tobacco cultivar'Yu Nongxiang 201'and conducted field experiments in 2022 in Weidu District of Xuchang City and Ziyun Town of Xiangcheng County,within the central Henan tobacco-growing region.Three treatments were established:foliar spray(T1),root irrigation(T2),combined foliar spray+root irrigation(T3),with water as control(CK).The study systematically examined their effects on agronomic traits,photosynthetic characteristics,dry matter allocation,and yield-quality parameters.Results indicated that polycarbonate enzyme application significantly promoted plant development,enhanced dry matter accumulation and rootward allocation,improved leaf photosynthetic rate,and increased yield and economic value of cured leaves compared to CK.T1 treatment achieved the greatest improvements in sugar-to-nicotine ratio and potassium-to-chloride ratio,enhancing the coordination of chemical components and elevating appearance quality indicators such as structure,texture,oil content,color intensity,and hue.T2 treatment maximized the proportion of upper-middle grade leaves,optimizing the grade structure of cured tobacco.T3 treatment increased tobacco yield by over 10%but reduced the proportion of upper-middle grade leaves,with declines observed in leaf structure and sugar-to-nicotine ratio,indicating a potential yield-quality trade-off.In conclusion,sole foliar application(T1)effectively balanced yield maintenance with improvements in photosynthetic carbon assimilation efficiency and rational dry matter distribution,achieving simultaneous optimization of chemical coordination and appearance quality.This approach aligns with the practical requirements for high-quality tobacco production in the central Henan region.关键词
