Abstract
In order to find the optimum fertilizing technology for tobacco K326,the experiments were conducted in Liuyang in 2011 to study the effects of N fertilizer rate,ratio of basal fertilizer to topdressing fertilizer,types of topdressing fertilizer and applying methods of basal fertilizer on yield and quality of tobacco leaves.The results indicated that when N fertilizer rate was 165 kg/hm 2,the agronomic characters,the ratio of middle-superior tobacco leaves,the yield and the output value of tobacco were the highest;when N fertilizer rate was 135 kg/hm 2,the agronomic characters were good,the chemical components were harmony,and the average price was the highest;when the ratio of basal fertilizer to topdressing fertilizer was 60% basal fertilizer +40% topdressing fertilizer,the effect was the best;among the topdressing fertilizers,diammonium phosphate had the best effect,and the best fertilizer applying method was applying in the planting hole.
