为探明不同量化学氮肥配施有机肥(菜枯,M)对烟草云烟87品质、氮素吸收及利用率的影响,探讨适合贵州省黔东南州烟草种植区的最佳有机无机施氮量,以期为烟草生产的减肥降本、增产提质增效提供技术参考。采用田间小区试验,设置CK_1、CK_2、MN_iPK( i = 0或1或2或3) 6个施肥处理,分析各处理烟叶的品质、各处理烟株的吸氮量及氮利用率。结果表明:与CK_2处理相比,MN_1PK、MN_2PK和MN_3PK处理烟叶总糖含量分别提高8.57%, 14.18%, 13.03%;烟叶还原糖含量分别提高4.67%,9. 66%,8. 26%;烟叶钾含量分别提高8.34%, 19.08%, 17.12%;烟叶氯含量分别降低0.36%,8.19%,3.56%;提高了钾氯比和两糖差;与CK_2处理相比...

The aim of this study was to reveal the effects of application rates of chemical nitrogen( N) fertilizer combined with organic fertilizer( rapeseed cake,M) on the quality,N uptake and use efficiency of tobacco Yun yan 87,and to find the best organic and inorganic N application amount of tobacco in Qiandongnan prefecture of Guizhou Province,which could provide the technical reference for reducing the production cost,and increasing the yield and quality of tobacco. Six treatments,i. e. CK_1,CK_2 and MN_iPK( i = 0,1,2 or 3) were set in a field plot experiment. The effects of each treatment on the...
