Effects of Optimized Fertilization Structure on Growth,Yield,and Quality of Flue-Cured Tobacco
摘要
Abstract
[Objective]This study was conducted to identify an optimal fertilization regime for high-quality,high-efficiency production of flue-cured tobacco in the typical tobacco-growing regions of Yong-zhou,Hunan Province.[Method]A field experiment was performed using the flue-cured tobacco cultivar'Yunyan 87'.Based on a conventional fertilization(T1),five fertilization modes were set up:T1 plus additional rapeseed cake fertilizer(T2);T1 supplemented with two different rates of potassium(K)fer-tilizer(T3,T4);synergistic application of conventional fertilizer,rapeseed cake(150 kg/ha),supple-mental K fertilizer(75 kg/ha),and foliar fertilizer(T5);T1.The effects of these fertilization regimes on tobacco growth,agronomic traits,economic yield,and key chemical components were systematically evaluated.[Result]The results showed that all optimized fertilization treatments improved tobacco quality and efficiency to varying degrees relative to the conventional control.Among them,the T5 treatment(conventional fertilization+150 kg/ha rapeseed cake+75 kg/ha supplemental K fertilizer+foliar fertilizer)demonstrated the best overall performance.T5 significantly increased the maximum leaf area at the squa-ring stage.Its yield and economic value were the highest among all treatments,which were 4.1%～10.9%and 2.8%～9.7%,respectively,over other treatments.Furthermore,chemical analysis revealed that T5 produced a more balanced chemical profile in the middle and upper leaves.The total sugar content of middle leaves reached 18.91%under T5,which also effectively mitigated the issue of an imbalanced sugar-to-nicotine ratio caused by excessive nicotine accumulation,as observed in T4.[Con-clusion]The integrated fertilization strategy of combining conventional application with rapeseed cake,ap-propriate K fertilizer,and foliar fertilizer(T5)is a promising approach for achieving coordinated im-provements in yield and quality for flue-cured tobacco production in the Yongzhou region.关键词
