摘　　要：以＂达白1号＂为材料,研究了不同施氮量不同基追肥比例对达州地区白肋烟农艺性状,产量和氮肥利用率的影响.结果表明施氮量和基肥比例对白肋烟的农艺性状、经济性状、干物质积累动态,都有不同程度的影响.随着施氮量的增加,白肋烟的产量、产值、上中等烟比例有增加趋势.0-210 kg.hm-2施氮量条件下,相同施氮量下随着基肥比例的减小,烟叶的产量、产值、上中等烟比例有增加趋势,当施氮量超过210 kg.hm-2时基追肥比例的影响效果不明显.从农艺性状、经济性状和氮肥利用率方面综合来看,以施氮量210 kg.hm-2为最好,255kg.hm-2次之,120 kg.hm-2最差,在施氮量为0-210 kg.hm-2,以基肥比例为40%最好,60%次之,80%最差.Taking ＂Dabai 1＂ as the materials, this paper studied the influence of dazhou region burley tobacco on agronomic characters, yield and efficiency of nitrogenous fertilizer in different nitrogen and different proportion of basal. The results show that nitrogen and basal proportion are of different influences on agronomic characters, economic characters, dry matter accumulation dynamics. With the increase of nitrogen rate, hurley tobacco has the increase trend in output, output value, the proportion of the superior and secondary tobacco. When nitrogen is in the scope of 0 - 210 kg · hm-2, under the same application rate of nitrogen fertilizer and with the decrease of the basal proportion, tobacco output, output value and the proportion of the superior and secondary tobacco increases. When the nitrogen is more than 210 kg· hm-2, basal proportion of influence is not obvious. Taken together, nitrogen 210 kg · hm-2 is the best, 255 kg · hm-2 neonatal and 120 kg · hm-2 worst. In the scope of 0-210 kg · hm-2, basal ratio for 40% being the best, 60% the second place, 80% the worst.
