Regional Characteristic and Spatial D istributions of Total Nitrogen Contents of Flue-cured Tobacco in Xiangxi Autono mous Perfecture
摘要
Abstract
The total nitrogen content of flue -cured tobacco from main tobacco -growing areas in Xiangxi Autonomous Perfecture were determined by continuous flow method,and its regional characteristic at grades,varieties,soil types,eleva-tion and different counties were also studied.The results showed that the mean total nitrogen content in the flue-cured to-bacco leaf of B2F,C3F and X2F grade were 2.16%,1.76%,1.68%,respectively,which showed that the area belonged to lower-nitrogen tobacco-planting areas.The sequence of total nitrogen content were:B2F>C3F>X2F.There were ex-treme significant difference in the total nitrogen content of flue-cured tobacco among grades and counties;and significant difference among soil types in B2F grade;and non-significant difference among varieties and elevation.The total nitrogen content decreased gradually from the south to the north.关键词
