云南优质白肋烟种植的关键技术研究现状与建议

为了提高云南白肋烟质量及可用性,引进国外白肋烟种质资源,筛选出产质兼优、抗病性强、适合云南生态区种植的优良品种TN86,并自育出 YNBS1。通过开展栽培、晾制、病虫害防治技术研究,总结出云南优质白肋烟生产技术规范。生产示范显示田间长势整齐清秀,晾制颜色均匀,烟 碱含量适宜,化学成分协调,内外在质量明显提高,为云南白肋烟产区提供了优良品种及适合优良品种种植的配套技术。

Present Status and Suggestions for the Studies on Key |Technology of Planting Burley Tobacco with Superior Quality in Yunnan

In order to improve the quality and usability of Yunnan burley tobacco, we introduced foreign germ plasm resources from aboard and screened a good variety TN86 with high yield, good quality, high resistance to diseases and high adaptability to ecological condition in Yunnan, and afterward selected and bred a new variety YNBS1. Through studying the technologies for cultivation, curing, disease and insect control, we summarized a set of technical specification for producing Yunnan burley tobacco with superior quality. At the production demonstration field, Yunnan burly tobacco grew tidily. Its color of air- curing was uniform. The nicotine content was appropriate and the chemical constituents were in harmony. Its internal and external qualities were obviously improved. Thus, a good variety and a set of cultivation technologies were provided to Yunnan burley tobacco producing area.
