摘要
在硫酸钾施用总量相同(20 kg/667m2)的基础上,采用田间试验对钾肥不同施用方法对烤烟产量和品质的影响进行了研究。结果表明:钾肥6种施用方法对烤烟生育期无明显影响;从经济性状来看,各处理之间差异显著,其中以T5处理(25%作基肥,75%作追肥,在移栽后25 d、35 d分2次追施,两次施用量相同,各占50%)在产量、产值、上中等烟比例等方面表现最好,抗赤星病较强。
Based on the same total fertilizer rate of potassium（300 kg/hm2）,effects of different application methods of potassium on yield and quality of flue-cured tobacco were studied using field experiments.The results showed that there are no obvious effects of six different application methods of potassium on growth period of tobacco.In terms of economic characters,there are significant differences between each treatment.Among all of the treatments,T5（25% as base fertilizer and 75% as top dressing are applied at 25 d and 35 d after transplanted with the same fertilizer rate,respectively） had the best performances in yield,output value and ratio of superior tobacco to medium tobacco,and the tobacco with T5 has strong resistance against brown spot disease.
