摘要
为提高烤烟的物理和经济性状,通过大田试验研究了磷酸二氢钾不同施用量(15kg/hm^2、30kg/hm^2、45kg/hm^2)对烤烟产质量的影响。结果表明,磷酸二氢钾根外喷施,能明显提高烤烟烟株的田间长势、物理性状,增强抗病能力,提高烟叶的经济性状。4个处理中,以T4处理(45kg/hm^2)效果最佳。
In order to improve the physical and economic characteristics of Flue-cured tobacco,field experiments were conducted to study the effects of different application rates of potassium dihydrogen phosphate(15kg/hm^2、30kg/ hm^2、45kg/hm^2)on the yield and quality of Flue-cured tobacco. The results showed that potassium dihydrogen phos. phate root spraying could significantly improve the field growth and physical properties of tobacco plants,enhance disease resistance and improve the economic characteristics of tobacco leaves. T4 treatment(45kg/hm^2)was the best among the four treatments.
