摘要: 培育壮苗是生产优质烤烟的前提条件,中国当前普遍采用的漂浮育苗技术存在许多不足,为提高烟苗的品质,以云烟87为材料,研究其在不同浓度生根粉条件下对苗床期烟苗生长的影响。结果表明,1.1 kg基质与25 mg生根粉混合能提高烟苗的质量,主要表现在茎干变粗,根长度增加,一级、二级侧根数目增加,根系活力提高;反之,超过一定浓度后,生根粉会降低烟苗的素质或效果不明显。

Abstract: Cultivation of strong seedlings is a prerequisite for the production of high-quality flue-cured tobacco, there are many deficiencies in the floating seedling technology currently commonly used in China. The results showed that 25 mg rooting powder mixed with 1.1 kg substrate can improve the quality of tobacco seedlings, mainly manifested in thicker stems, increased root length, increased number of first and second side roots, and improved root vigor. On the contrary, after a certain concentration, rooting powder will reduce the quality or effect of tobacco seedlings.

Key words: flue-cured tobacco, rooting powder, floating seedling, growth and development
