以‘冬红’海棠、‘高原之火’海棠为研究材料,对其进行了聚乙烯硬质控根容器、无纺布软控根袋、AB双层盆控根容器的海棠大苗控根容器育苗试验。结果表明:(1)在硬容器、全地下软容器成活率达到了99%以上,AB双层盆的成活率分别为95%、96%,能够获取较高的成活率。(2)‘冬红’海棠、‘高原之火’海棠在不同的控根器育苗时,树高、地径、冠幅、当年生枝长、当年生枝基径及根系的生长量差异明显。平均的生长量由大到小的顺序为:全地下无纺布控根器≥全地上硬质塑料控根器≥AB双层盆控根器。
Taking Begonia macrophylla and Begonia officinalis as the research materials, this paper carried out the control of polyethylene terephthalate root container, non-woven soft control root bag, AB double-layer potted root container Nursery test. The results showed that: (1) Survival rate of hard container and all-ground soft container reached more than 99%. The survival rate of AB double-layer pots was 95% and 96%, respectively. (2) ’Begoniaceae’, ’Fire of the Highland’ Begonia seedlings in different controllable root, nursery height, diameter, crown width, annual branch length, year branch diameter and root growth significantly different. The average growth of descending order of order: all underground non-woven control device ≥ all over the hard plastic control device ≥ AB double basin control device.
