【摘要】：采用田间小区对比试验,以河南烟区广泛种植的豫烟10、豫烟12和中烟100为供试品种,研究了3种基因型烤烟的氯吸收、积累与分配规律,以期筛选出适宜河南烟区的低氯型烤烟。结果表明,在整个生育期,豫烟10烟叶氯含量为0.62%~0.91%,豫烟12为0.54%~0.82%,中烟100为0.43%~0.67%,豫烟10和豫烟12烟叶中氯含量部分超过0.8%,而中烟100均符合优质烟叶氯含量0.8%的要求。移栽后30~75 d,是烟叶吸收积累氯的关键时期,且各生育期烟叶氯积累量均呈现豫烟10豫烟12中烟100的规律。各基因型烤烟均以叶中氯分布最高,为44.75%~77.35%,其次是茎,为12.22%~47.52%,根仅为1.66%~11.21%。与其他处理相比,中烟100烤后烟叶化学成分含量适宜,且其生物产量分别是豫烟10和豫烟12的1.14和1.50倍。综合来看,中烟100是供试区烟叶氯含量较低的基因型烤烟。
[Abstract]:The chlorine uptake, accumulation and distribution of three flue-cured tobacco genotypes, Yuyan 10, Yuyan 12 and Zhongyan 100, which were widely planted in Henan tobacco area, were studied by field plot contrast experiment. The purpose of this study was to screen out low chlorine flue-cured tobacco suitable for Henan tobacco area. The results showed that during the whole growth period, the chlorine content of Yuyan 10 tobacco leaf was 0.620.91, Yuyan 12 0.54 and 0.82, Zhongyan 100 0.430.67, Yuyan 10 and Yuyan 12 more than 0.8%, and Zhongyan 100 met the requirement of 0.8% chlorine content in high quality tobacco leaf. 30 ~ 75 days after transplanting, it was the key period for tobacco leaves to absorb and accumulate chlorine, and the accumulation of chlorine in tobacco leaves at each growing stage showed the rule of Yuyan 10, Yuyan 12 and tobacco 100. The distribution of chlorine in the leaves was the highest among all the genotypes of flue-cured tobacco, which was 44.75 and 77.35, followed by the stem, which was 12.22 and 47.52, and the root was only 1.66 and 11.21. Compared with other treatments, the content of chemical components in leaves of Zhongyan 100 was suitable, and its biological yield was 1.14 and 1.50 times higher than that of Yuyan 10 and Yuyan 12, respectively. In general, Zhongyan 100 was the genotype of flue-cured tobacco with low chlorine content in tobacco leaves.
