湖北自育烤烟新品系的区域适应性研究

Regional adaptation study on new flue-cured tobacco strains in Hubei province

为探索湖北省不同环境条件对自育烤烟新品系的影响,选用烤烟新品系HB104、HB204、HB205为试验材料,以云烟87为对照,连续2年在湖北省利川市凉雾乡、兴山县黄粮镇、竹山县官渡镇、保康县马良镇4个区试点进行小区对比试验,分析3个烤烟新品系在湖北省4个区试点的产值、内在化学成分的差异性。结果表明,新品系HB204连续2年在4个区试点的平均产值高于对照云烟87,适应性、稳定性明显好于对照云烟87,平均烟碱、总氮含量、总糖、还原糖、氯离子含量与对照云烟87基本相当,钾离子含量高于对照云烟87,内在化学成分整体协调性较好,最适宜在湖北各产区推广种植。

To explore different environmental conditions on the new bred flue-cured tobacco strains agriculture in Hubei province,the new flue-cured tobacco strains HB104,HB204 and HB205 were selected as experimental materials,Yunyan 87 used as the control,plot contrast test for two years were carried out in Lichuan city Liangwu township,Xingshan county Huangliang town,Zhushan county Guandu town,Baokang county Maliang townin in Hubei province,the differences of output value and intrinsic chemical composition on three new flue-cured tobacco strains at four pilot areas in Hubei province were analyzed. The results showed that the average output value of the new strain HB204 in two consecutive years was higher than that of the control Yunyan87,which were better at adaptability and stability than that of the control Yunyan87,and were almost the same at the average contents of nicotine,total nitrogen,total sugar,reducing sugar and chloride ion as that of the control Yunyan87,and was higher than that of the control Yunyan87 at the content of potassium ion,and the overall coordination of internal chemical composition of that was good,which was the most suitable for spreading planting in all producing areas of Hubei province.
