以NC89为对照,研究了烤烟品种龙江237在黑龙江烟区的农艺性状、生育期性状、抗病性、经济性状、外观质量、物理性状、化学成分和感官质量等指标。结果表明,龙江237在黑龙江烟区长势强、生育期长、需氮量小,对TMV免疫;产量、级指、产指分别比对照提高10.46%、8.00%、18.41%,上等烟比例略高于对照;外观质量、物理特性较好,钾含量、香气质、杂气、劲头、刺激性和余味等需进一步改善或提升。
Using NC89 as control, the indexes of agronomic traits, growth traits, disease resistance, economic traits, appearance quality, physical properties, chemical composition and sensory quality of flue-cured tobacco variety Longjiang 237 in Heilongjiang tobacco growing area were studied. The results showed that Longjiang 237 had a strong growth period, long growth period, low nitrogen requirement and immunity to TMV. The yield, grade index and birth index increased by 10.46%, 8.00% and 18.41% respectively compared with the control, Slightly higher than the control; appearance quality, physical properties are better, potassium content, fragrance quality, gas, momentum, irritation and aftertaste need to be further improved or improved.
