Main Characteristics of a New Flue- cured Tobacco Variety Longjiang981 in Heilongjiang Tobacco- growing Area

[目的]分析烤烟新品种龙江981在黑龙江烟区的主要性状表现。[方法]以NC89为对照,从农艺性状、生育期性状、抗病性、经济性状、外观质量、化学成分和感官质量等方面,对由黑龙江种植的烤烟新品种龙江981进行了分析评价。[结果]在黑龙江烟区生态条件下,龙江981长势强、耐肥性好、易烘烤,抗PVY,中抗赤星病;产量、等级指数、产值指数分别比对照提高12.29%、11.76%、24.34%,上等烟比例增加5.40个百分点;外观质量较好。[结论]龙江981具有较稳定的农业经济效能和较高的农业应用性,钾含量、香气质、杂气和刺激性等需进一步改善或提升。

[ Objective] The research aimed to analyze the main characteristics of a new flue-cured tobacco variety Longjiang981 in Heilongjiang tobacco-growing area. [ Method] Taking NC89 as control,the agronomic characters, characters in growth period, tolerance to diseases, economic characters, appearance quality, chemical components and sensory quality of new flue-cured tobacco variety Longjiang981 in Heilongjiang tobacco- growing area were studied. [ Result] Longjiang981 was resistant to PVY, moderately resistant to brown spots, grew strongly, good tolerance to high fertilizer , easy to cure. Besides, the yield, grade index and output value index respectively 12.29%, 11.76%, 24.34% higher than that of con- trol, the ratio of superior tobacco increased 5.4 percentage points. Longjiang981 was good at the appearance quality. [ Conclusion ] Longjiang 981 had a stable agricultural economy efficiency and higher agricultural application, the potassium, aroma quality, odor and irritation of tobaccos need to further improve or promotion.
