摘要
选用木荷Schima superba,湿地松Pinus elliottii,苦槠Castanopsis sclerophylla,青冈Cyclobalanopsis glauca,杨梅Myrica rubra,樟树Cinnamomun camphora,无患子Sapindus mukorossi和红叶石楠Photinia serrulata等浙江省主要生态经济造林树种,开展容器类型和规格对其1~2年生容器苗生长影响的系统研究。结果表明,不同树种容器苗对不同容器类型和规格的生长反应差异很大。对于1年生容器苗培育,以无纺布网袋容器作为育苗容器的各树种容器苗生长表现最优,在林木穴盘、塑料薄膜容器和软质塑料杯等3种育苗容器中各树种容器苗生长均属正常,而硬质锥形塑料管和纸杯容器其容器苗生长表现较差;对于2年生容器大苗培育,以可拆式塑料容器作为育苗容器的各树种容器苗生长表现皆显著优于其他类型容器,以无纺布网袋容器为育苗容器的各树种容器苗生长均较好,以软质塑料杯和纸杯容器为育苗容器的容器苗生长较差。相关分析发现,各树种1年生容器苗的苗高、地径、干物质积累量和根体积等生长性状与育苗容器直径和高度相关性不显著,而各树种2年生容器苗的主要生长性状与容器规格皆呈显著的正相关,意味着为培育2年生的容器大苗,选择规格较大的容器是关键的技术措施之一。
To aid in seedling container selection for important ecological and economic afforestation species（Schima superba,Pinus elliottii,Castanopsis sclerophylla,Cyclobalanopsis glauca,Myrica rubra,Cinnamomum camphora,Sapindus mukorossi,and Photinia serrulata） in Zhejiang Province,effect of container types（non-woven fabric containers,tree plugs,plastic film containers,soft plastic cups,hard conical plastic tubes,paper cup containers and demountable plastic containers） and sizes（container diameter and height） on the annual and biennial seedling growth of the afforestation species mentioned above were determined using the variance and simple correlation analysis.A random block design with three replications were applied in the trials,and the traits survey were conducted in late October of 2008.Result showed significant（P0.05） differences among different container types and sizes in seedling growth of different species.The LSD multiple range test result showed that,in the annual seedling trial,seedlings in non-woven fabric containers grew best;seedlings in tree plugs,plastic film containers,and soft plastic cups exhibited a moderate growth increment;and seedlings in hard conical plastic tubes and paper cup containers grew slower.For biennial seedlings,demountable plastic containers were the best followed by non-woven fabric containers that exhibited a relatively large growth increment and then soft plastic cups and paper cup containers where seedlings grew more slowly.For annual seedlings,no significant correlations between growth traits（seedling height,base diameter,dry matter,root volume） and container diameter and height were found.However,for biennial seedlings there were significant positive correlations（P0.05,r = 0.758-0.986） between the growth traits and container diameter and height.Based on the seedling quality,production cost and afforestation effect,non-woven fabric containers were the superior container type for the species.Moreover,selecting a relatively large container type was key to
