A Study of Application of Multicavity Tray on Container Seedling Nursing of Eucalyptus maidenii in Panzhihua and Xichang Region

对四川攀西地区直干桉多穴容器盘的育苗效果进行了研究,研究结果表明:(1)多穴容器盘育苗能从根本上解决容器苗的根系盘绕现象;(2)多穴容器盘培育直干桉容器苗宜采用容积为150 mL以上的导根线类多穴容器盘;(3)攀西地区多穴容器盘培育直干桉容器苗的最佳基质配方为燥红土5%+泥碳土35%+60%牛粪。

The effects of seedling nursing of E. maidenii in Panzhihua and Xichang region by using multicavity tray were studied. The results were as follows： 1 ） The root coiling problem could be entirely avoided by seedling nursing in multicavity tray; 2） the suggested seedling nursing container for E. maidenii was root-conducting container tray with individual volume over 150 mL; 3 ） The best medium for seedling nursing of E. maidenii was 5 % of dry red soil, 35 % of peat soil and 60 % of cow dung.
