留叶数对烟叶综合性状的影响研究
摘要采用多因子裂区试验设计,研究留叶数对K326、HY-9-7综合性状的影响。结果表明:在相同的栽培条件下,品种HY-9-7的长势、抗病性均强于K326,产量、产值高于K326,外观质量优于K326。在中等肥力条件下,品种K326的适宜留叶数为20~22片/株,HY-9-7为18~20片/株。

AbstractA multi-factor split-plot experiment was conducted to study the effect of remained leaves on comprehensive characteristics of flue-cured tobacco variety K326 and HY-9-7. The results showed that,in the same cultivation conditions,the growth vigor and disease resistance of HY-9-7 were stronger than K326,the yield and output value were higher than K326,and the appearance quality was better than K326. In the medium-fertility conditions,the appropriate number of remained leaves was 20~22 pieces per plant for K326 and 18~20 pieces per plant for HY-9-7.

品种是提高烟叶产量和质量的重要因素[1-2]。郴州烟区长期以来在烤烟生产上存在推广品种较少、种植品种相对单一的问题,现有主栽品种云烟87占郴州植烟面积60%~65%,且已连续种植多年,K326由于上部烟叶商品等级不高和烟碱含量偏高等,在全市的推广规模一直局限在30%左右。为了改变这种不利的局面,筛选出适合当地的优良新品种,实现烤烟种植品种多样化,布局合理化,对烤烟新品种HY-9-7进行引进示范和打顶留叶配套栽培试验。烤烟是叶用经济作物,打顶留叶是调节烟株营养的重要手段[3-5],留叶数多少不仅与产量高低有直接...
