不同施氮量对几个烤烟品种生长发育和经济性状的影响

通过大田对比试验，研究了不同施氮量对云烟97、云烟99、K326的生育期、农艺性状和经济性状的影响，结果表明：云烟99＋135kg／hm^2施氮量处理的农艺性状表现较好，K326＋75kg／hm^2施氮量的处理表现较差，云烟97＋135kg／hm^2施氮量处理的纯收入最高，达36338．4元／hm^2；K326＋75kg／hm^2处理的纯收入最低，为20864．85元／hm^2，其他处理的纯收入均在25500—30000元／hm^2之间，投入产出比达1：3以上。...

Flue -cured tobacco; Nitrogen application rate; Agronomic character; Economic trait
Field experiments were carried out to study the effects of different nitrogen application rates on the growth period, agronomic and economic characters of Yunyan 97, Yunyan 99 and K326. The results indicated that Yunyan 99 possessed better agronomic characters at the nitrogen application rate of 135 kg/hm2 , while the agronomic characters and economic traits of K326 had poor performances at the nitrogen application rate of 75 kg/hm2. The net income of Yunyan 97 was the highest at the nitrogen application rate of 135 kg/hm2, and reached 36338.4 yuan/hm2. The net income of K326 was the lowest （20864.85 yuan/hm2 ） when the nitrogen application rate was 75 kg/bm2. The net incomes of oth
