蒲葵大树移植的关键技术

THE KEY TECHNIQUES OF LIVISTONA CHINENSIS BIG TREE TRANSPLANTING

蒲葵是一种优良的园林绿化树种 ,但大树移植较困难。作者根据 1 3批共 6 50 7株蒲葵大树移植的经验 ,着重讨论了影响蒲葵大树移植成活的关键技术。在树体选择、移植季节、吊根处理、树苗起挖、装卸运输、移栽定植及植后管理等各个技术环节中 ,最重要的是要掌握好吊根处理和树体保护。吊根时间以 3～ 4个月为宜 ,断根长度为 1 2～ 1 5cm可满足移植成活的要求。树体保护除保证树头土球完整外 ,还要保护好树干和树梢 。

Livistona chinensis is a good species for landscape engineering, but its big tree transplanting is difficult. Based on the experience of big tree transplanting (13 times, total 6 507 trees), the paper put forward the key techniques of Livistona chinensis big tree transplanting, such as sapling selecting, transplanting season, lateral root cutting, soil ball digging, loading and transporting, field planting and management. Lateral root cutting and tree protecting process are most important. Cutting lateral root for 3 to 4 months is suitable for transplant. Soil ball keeping 60 cm diameter and 45 cm deepth meets transplants demands. Keeping soil ball undamaged and preventing tree top and trunk from being hurt are also important.\;
