泡桐的种子、根、茎干均可繁殖.我省普通采用埋根育苗,方法简单,出苗粗壮,但其最大缺点是种根易带丛枝病病源体,易遭丛枝病危害,且发病率一年比一年严重.与埋根育苗相反,种子育苗的优点正好能克服埋根育苗的缺点,种子资源丰富,一个泡桐果一般有一千多粒种子,播种育苗所需的种子量又较少,故在短期内能提供大量苗木;而且自花不孕所结种子都是异花授粉种子,在多种泡桐杂生地区容易获得天然杂种,利用其杂种优势,提高生活力,可望从中选出优良的类型;泡桐种子不带丛枝病病源体,种子育苗可有效控制丛枝病的传播和蔓延.因此,应大力提倡泡桐种子育苗.
Paulownia seed, roots, stems can be multiplied. In our province, the use of embedded root nursery, the method is simple, robust, but its biggest drawback is the root easy to bring birch disease pathogens, susceptible to the broom disease hazards, and the incidence The rate of serious year after year .In contrast with the burgeoning seedlings, the advantages of seedling nurseries just to overcome the shortcomings of seedling roots, seed rich in resources, a Paulownia fruit generally have more than a thousand seeds, seeding the seed required for seedling and Less, so in the short term can provide a large number of seedlings; and self-infertility knot seeds are cross-pollination seeds in a variety of Paulownia heterozygous easy access to natural hybrids, the use of its heterosis and improve viability, is expected Paulownia seed without the pathogen of the broom disease, seedling can effectively control the spread and spread of the broom disease.Therefore, we should vigorously promote Paulownia seedling.
