摘要
2011、2012年对湖北省自育烤烟新品系HB023在清江流域和环神农架地区布点示范,从田间农艺性状、抗病性、经济性状、化学成分和感官质量等方面进行综合评价,同时探讨了不同氮肥施用量对其农艺性状、经济性状和品质性状的影响.结果表明,HB023在农艺性状、抗病性状和经济性状上优于主栽品种K326,而与云烟87相当,在品质方面接近或相当于K326.增加氮肥施用量能够提高HB023的产量和产值,但烟叶品质变劣,氮肥施用量以90.0～97.5 kg/hm2为宜.
In 2011 and 2012,new flue-cured tobacco strain HB023 from Hubei Province were demonstrated in the Qingjiang area and Shennongjia area,and evaluated comprehensively from in agronomic traits in the field,disease resistance,economic characters,chemical components and sensory quality and so on.The effects of different application rate of nitrogen fertilizer on its agronomic trait,economic characters and quality traits were investigated.Results showed that HB023 had better agronomic traits,disease resistance and economic character than those of K326,the equivalent of Yunyan 87.In terms of quality,it was close to or equal to K326.The increase of application rate of nitrogen fertilizer could increase the yield and output value of HB023,but the quality of tobacco leaf became worse.It suggested that the application rate of nitrogen fertilizer was betwen 90.0 kg/ha and 97.5 kg/ha.
