1题目 不同烤烟新品种对比初步研究摘 要鉴于芒市烤烟品种退化,为筛选出尤为适合芒市地域种植的新型烤烟,本文 旨 在 借 助 于 大 田 试 验 , 针 对 现 有 的 新 型 烤 烟 ( 云 烟116、119、207、218、219、220)的适应性、抗病性、经济效益、质量特点等进行研究比较,以云烟 220,云烟 207、云烟 218 综合性状较好,可以考虑在调整作物布局的基础上扩大试种面积,进一步验证后实行大面积推广种植。关键词:烟草品种;筛选;试验;ABSTRACTIn view of the degradation of flue-cured tobacco varieties in Mangshi, in order to screen out new varieties of flue-cured tobacco suitable for cultivation in Mangshi, the adaptability of new varieties of flue-cured tobacco (Yunyan 218 、 Yunyan 207, Yunyan 116 、 Yunyan 119 、 Yunyan 220 、 Yunyan 219) Disease resistance, economic benefits , quality characteristics , etc. are studied and compared. The comprehensive characteristics of Yunyan 220 , Yunyan 207 and Yunyan 218 are better. It is possible to consider expanding the trial area on the basis of adjusting the crop layout, and further expanding the planting after further verification.
