摘  要：
以河南省目前种植面积较大的中烟100为试验材料,研究氮肥不同施用措施对烟叶产量、含氮化合物及氮肥利用效率的影响。结果表明,与不施氮处理相比,施氮显著提高了烟叶产量、产值和含氮化合物含量,烟叶产量和产值分别增加10.0%～56.7%、11.6%～43.1%。在相同施氮量条件下,随着追施氮比例增加,烟叶产量和含氮化合物、氮肥利用效率增加,烟叶产值在施氮37.5 kg/hm2水平随着氮肥追施比例增加而增加,而在施氮60kg/hm2和82.5 kg/hm2水平均以氮基施75%、追施25%处理最高。在氮基追比例相同条件下,烟叶产量和含氮化合物及氮肥贡献率随着施氮量增加而增加,氮肥偏生产力随着施氮量增加而降低,氮肥吸收利用率和烟叶产值均以N 60 kg/hm2处理最高。从烟叶产量和含氮化合物适宜,提高烟叶产值和氮肥利用率方面综合分析,在本试验中,以施氮60.0 kg/hm2,氮50%～75%基施、25%～50%追施处理表现最优。

摘  要：
The most popular tobacco cultivar,Zhongyan 100,in Henan province was used to study the effects of different application measures of nitrogen(N) on yield of flue-cured tobacco,N use efficiency and nitrogenous compounds of tobacco leaves.The results show that compared with the control treatment(without nitrogen),the yields of tobacco leaves,nitrogenous compounds and N use efficiencies are significantly increased under the N application treatments,and the yields and the production values are increased by 10.0%-56.7% and 11.6%-43.1%,respectively.Under the same amount of nitrogen application,with the increase of topdressed nitrogen rate,the yields,nitrogenous compounds and N use efficiency of tobacco are increased.At the N application level of 37.5 kg/ha,the production value is increased with the ratio of topdressed N to basal N fertilizer increasing.The treatment of 75% basal N and 25% topdressed N has the highest production values under both 60 kg/ha N application level and 82.5 kg/ha N application level.At the same ratio of basal N to topdressed N fertilizer,the partial factor productivity of the applied N is decreased with the nitrogen application increasing,and the N use efficiency and the production value are the highest under the N 60 kg/ha level.Based on the comprehensive analysis of the yields of tobacco leaves,appropriate nitrogenous compounds,increases of the production value and the N use efficiency,the treatment with the best effect is the amount of nitrogen application at 60.0 kg/ha and the proportion of basal N application at 50%-75%.
