烤烟不同品种与其产量和品质的关系

对 Ｋ３４６、 Ｋ３５８、 Ｋ７３０、 Ｒ Ｇ１１、 Ｒ Ｇ１７、９２０１、岩烟 ９７、 Ｋ３２６（ Ｃ Ｋ）８ 个烤烟品种的生育期、植物学性状、产量、质量及其烟叶的评吸进行分析研究，结果表明，参试品种间的生育期差异不大，打顶后各品种的株形基本是筒形，叶形属长椭圆形，但 Ｒ Ｇ１１ 的腰叶长度较长， Ｋ３５８、 Ｋ７３０ 叶片稍宽．单位面积产量、产值以岩烟 ９７ 为最高，分别为 ２ ４９７．５ ｋｇ·ｈｍ － ２ 、１１ ３７３ 元·ｈｍ － ２．各品种单位面积产量由高到低的顺序是：岩烟 ９７＞ Ｋ３４６＞ Ｒ Ｇ１７＞ Ｒ Ｇ１１＞ Ｋ３２６（ Ｃ Ｋ）＞ Ｋ７３０＞ ９２０１＞ Ｋ３５８，单位面积产值与产量的表现趋势大致相同．烟叶外观质量和内在质量以 Ｋ３４６ 为最好，上等烟比例最高，而 Ｒ Ｇ１７ 和 Ｋ３５８ 内在评吸质量最好．综合各项指标，可以得出如下初步结论： Ｋ３４６ 具有适应强、产量和品质优良等特点，应加大推广； Ｋ３５８、９２０１ 综合指标表现较差，不适宜我省烟区种植

Different varieties of cured tobacco and their relationship to yield and quality

The growth period, botanic characters, yields, quality and taste of K346, K358, K730, RG11, RG17, 9201, Yan Tobacco 97 and K326 (CK) were studied. The results were as follows. Firstly, there was no significant difference of growth period among these 8 varieties and the plants were mostly tubular after the top leaves emerged while the leaves were long oval in shape, but the middle leaves of RG11 were slightly longer and the leaves of K358 and K730 were wider. Secondly, Yan Tobacco 97, which was listed at the top in yield and output value, boasted 2 497.5 kg·hm -2 and 11 373 yuan per hectare. The sequence of yield and value per unit area in the varieties was Yan Tobacco 97>K346>RG17>RG11>K326(CK)>K730>9201>K358. Thirdly, K346 was the best in exterior and interior quality as well as the highest in the scale of superior tobacco, while RG17 and K358 possessed the best taste. It was concluded that K346 was characterized to have high adaptability, yield and quality, and should be popularized, but K358 and 9201 were so far low in the synthetic indices, and inadaptable to grow in Fujian Province.
