【摘要】 经3年多点品种区域试验发现:品种与年份互作效应不显著,而品种效应、地点效应、品种与地点互作效应显著。表明参试品种间有产质上的差异,而其差异程度又随地点间的土壤、气候、耕作、管理等环境差异而异;造成烟叶产质变异的主要因素不是年度间的气候变化,而是固定因素品种和地点、尤其是品种因素及其与地点的互作。说明在烟叶生产中通过品种的合理布局,能较大幅度地提高各试点烟叶的品质。建议云南省烟区以云85,云87和K326为主栽品种,搭配种植K358,K346,G28和红大,局部烟区搭配种植云烟317,V2,RG11等品种,以适应云南省不同卷烟配方的需要。更多还原

【Abstract】 Tobacco variety is widely adapted to various regional conditions, but only being planted in areas with the right natural conditions, where the tobacco variety could fully show its potential of its quantity and quality. Through a 3-year multi-location trial of tobacco variety regionalization, the results showed there is no significant difference between the variety and the years, while there is significant difference between the variety, the location, and the interaction between variety and location which indicated that there existed difference between the varieties in quantity and quality, the degree of the difference is varied according to changes of soil, climate, cultivation and managements. The factors causing the variance of the leaf quantity and quality are not the Annual climate changes, but are the variety and the location, especially the interaction between the variety and the location. It demonstrated that reasonably arranging tobacco varieties according to suitable natural conditions, can greatly improve the leaf quality. It is recommended that flue-cured variety Yunyan85, Yunyan87 and K326 can be grown as the major varieties in Yunnan Province with certain rate of K358, K346, G28 and Hongda; in some areas, Yunyan 317,V2 and RG11 can be grown as major varieties, for all these are aimed at meeting the need of different brands of cigarette making.更多还原
