海棠大苗控根育苗技术研究

Study on Root Control Nursery Technology of Crabapple Trees

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。

Abstract： In ‘ winter red ＇ Crabapple, ‘highland Fire＇ Crabapple as research materials,take them on QC root hard polyethylene container, Soft non-woven root control bags, AB double basin control root container study. The results show that： （ 1 ） The Survive Rate of Crabapple in hard polyethylene container and Soft non-woven root control bags is obove 99%, and the Survive Rate of Crabapple in AB double basin control root container is 95% and 96%,they can get high Survival.Second. （2） In different root containers, the tree height, diameter, crown,Current year branch length,Current year basal diameter and root growth between ‘winter red＇ Crabapple and ‘highland Fire＇ Crabapple are different obviously.The average gowth from small to large is： Soft non- woven root control bags ≥ QC root hard polyethylene container≥ AB double basin control root container,
