烤烟新品种云烟116在兴义烟区的适应性研究

Study on the Adaptability of a New Flue-cured Tobacco Variet Yunyan 116 in Xingyi Tobacco Growing Area

为了解烤烟新品种云烟116在兴义烟区的适应性,采用大区对比试验,以当地主栽品种云烟87、K326作为对照,分析其田间农艺性状、植株抗病能力经济价值、原烟外观质量、物理特性及化学品质等特征特性。结果表明:云烟116植株生育期适中,田间农艺表现与对照相当,田间综合抗病能力较强,初烤烟叶产值明显高于2个对照品种,上中等烟率和级指最高,物理特性和外观质量与云烟87相当,烟叶化学成分含量适宜且各项比例协调。云烟116在兴义烟区适应性较好,种植效益较高,具有进一步大面积推广种植的潜力。

In order to understand the production suitability of the new flue-cured tobacco variety Yunyan 116 in Xingyi to-bacco area,a large-area comparative experiment was carried out with the local main varieties Yunyan 87 and K326 as the control.The agronomic characters,plant disease resistance,economic value,appearance quality,physical properties and chemical quality of raw tobacco were analyzed.The results showed that the growth period of Yunyan 116 was moderate,the agronomic performance in the field was similar to that of control,the comprehensive disease resistance was strong,the out-put value of the first flue-cured tobacco leaf was significantly higher than that of the two control varieties,the physical properties and appearance quality were similar to those of Yunyan 87,and the chemical composition content of tobacco leaves was suitable and the proportion was coordinated.Yunyan 116 has good adaptability and high planting benefit in Xingyi tobacco area,so it has the potential to popularize planting in a large area.
