氮用量及基追比例对烟叶产量、 品质及氮肥利用效率的影响

Effects of nitrogen fertilizer rates and ratios of base and topdressingfertilizer on yield, quality  of tobacco leaves and N-use efficiency

  • 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60 kg/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。

     

    Abstract: 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%.
