摘　　要：为探讨不同育苗容器规格对闽楠(Phoebe bournei)苗木生长的影响,采用随机区组设计,比较8个容器袋规格对苗高、地径生长的影响。结果表明:不同容器袋规格对闽楠的地径生长具有极显著的影响,地径生长量随容器袋底径的增大而提高;随着转袋培养年限的增加,各处理组的地径生长依然存在极显著差异,且差异有加速的趋势。闽楠的苗高生长表现为随着容器袋口径及容积的增大而呈先升高,后下降,再升高的趋势。对于培育1~2年生的轻基质营养袋苗,可以考虑使用D 18 cm×H 20 cm的无纺布袋,其转袋培育第1年苗高可达66.04 cm、地径可达6.99 mm;培育2年,苗高可达111.49 cm,地径可达9.83 mm;如果培育3~5年的闽楠中大苗,则应以较大规格的容器袋为宜。In order to explore the influence of different container specifications on the growth of Phoebe bournei seedlings,a random block design was adopted to compare the influence of eight container bag size on the growth of seedling height and ground diameter.Result shows that different container bag sizes have significant effects on the ground diameter growth of Phoebe bournei,and the ground diameter growth increase with the increase of the bottom diameter of the container bag,and the ground diameter growth of each treatment group still have very significant differences with the increase of the culture years of turning bags,and the difference had a tendency to expand.With the increase of container bag diameter and volume,the growth of seedling height of Phoebe bournei first increases,then decreases,and then increases.For the cultivation of light matrix nutrition bag 1-2-year-old seedlings,non-woven fabric bags of D 18 cm×H 20 cm can be considered.The height&ground diameter of the first year seedlings in the rotary bag cultivation can reach 66.04 cm and 6.99 mm respectively.After 2 years of cultivation,the seedling height can reach 111.49 cm and the ground diameter can reach 9.83 mm.However,if you want to breed medium and large Phoebe bournei seedlings for 3-5 years,it is advisable to use larger containers bags.
