摘要: 为筛选出培育降香黄檀(Dalbergia odorifera T. Chen)壮苗的适宜育苗基质,试验采用泥炭、珍珠岩、木材锯末粉和壤土为原料按照不同配比设置6种栽培基质,以无纺布育苗袋为育苗容器,测定栽培90 d后降香黄檀幼苗的生长及生理指标。结果表明,各栽培基质处理的降香黄檀幼苗生长及生理指标均有差异。其中处理3(即泥炭∶珍珠岩∶木材锯末粉∶壤土=12∶2∶2∶4)降香黄檀幼苗生长及生理代谢活性表现最好,且大部分指标显著优于对照(P<0.05),其总鲜重、总生物量、根冠比、单位质量根瘤数、根系活力、苗木质量指数分别是对照的2.37、2.46、1.29、2.90、1.31、2.84倍,因而处理3是本研究中降香黄檀育苗最佳栽培基质配比。此外,基质透气性也是影响降香黄檀壮苗培育的主要因子之一。

Abstract: In order to screen out the suitable seedling substrate for the cultivation of Dalbergia odorifera seedlings, peat, perlite, sawdust and loam were used as raw materials to prepare six kinds of cultivation substrates with different proportions, and the non-woven seedling bag was used as the seedling container. The growth and physiological indexes of Dalbergia odorifera seedlings were measured after 90 days of cultivation. The results showed that there were differences in growth and physiological indexes of Dalbergia odorifera seedlings treated by different culture substrates. Among them,treatment 3(peat∶perlite∶wood sawdust∶loam=12∶2∶2∶4) showed the best morphological growth and internal physiological metabolic activity, and most indicators were significantly better than those of CK(P<0.05). The total fresh weight, total biomass, root-shoot ratio, number of nodules per unit mass, root activity and seedling quality index were 2.37, 2.46, 1.29, 2.90, 1.31 and 2.84 times of CK, respectively. Therefore, treatment 3 was the best cultivation substrate ratio of Dalbergia odorifera seedlings in this study. In addition, matrix permeability was also one of the main factors affecting the cultivation of Dalbergia odorifera seedlings.
