摘要:

为明确有机氮(腐熟牛粪中的有机氮)替代化学氮的最佳比例,减少化学氮肥施用量,该研究采用田间试验,分析了有机氮部分替代化学氮对烤烟农艺性状、产质量以及烤后烟常规化学成分的影响。结果表明:在农艺性状方面,20%和40%的替代比例能够显著促进烟株的生长发育,综合农艺性状优于对照常规施肥CK和60%替代比例;在经济性状方面,40%替代比例的综合经济性状最优,20%替代比例次之,但2个处理差异不显著;在烤后烟化学成分方面,20%替代比例处理的化学成分及各成分之间的协调性较好。综合农艺性状、经济性状、化学成分协调性3个方面的表现,20%有机氮替代化学氮的综合表现最佳,40%替代比例次之。

Abstract:

To clarify the optimal ratio of organic nitrogen (organic nitrogen in decomposed cow manure) to replace chemical nitrogen, reduce the amount of chemical nitrogen fertilizer applied, this study used field experiments to analyze the effects of partial substitution of organic nitrogen for chemical nitrogen on the agronomic traits, yield and quality, as well as the conventional chemical components of flue-cured tobacco. The results showed that in terms of agronomic traits, the 20% and 40% substitution ratios could significantly promote the growth and development of tobacco plants, and the comprehensive agronomic traits were superior to the control conventional fertilization CK and the 60% substitution ratio; In terms of economic traits, the comprehensive economic traits with a 40% substitution ratio were the best, followed by a 20% substitution ratio, but the difference between the two treatments was not significant; In terms of chemical composition of flue-cured tobacco, the chemical composition treated with a 20% substitution ratio and the coordination between various components were better. The comprehensive performance of 20% organic nitrogen substitution was the best, followed by the 40% substitution ratio, in terms of agronomic traits, economic traits, and chemical component coordination.
