Effects of container size,matrix ratio and SRFon the growth and quality of Alniphyllum fortunei container seedings
[目的]通过研究苗基质配比、缓释肥用量、容器规格等因素及其组合对 2年生赤杨叶容器育生长和质量的影响，探讨赤杨叶容器苗在不同组合中的生长效果差异，筛选出最优育苗方案，为培育赤杨叶优质容器苗提供参考。[方法]以赤杨叶幼苗为材料，采用析因试验设计，设置 3种容器规格、3种基质配比和3种缓释肥用量，正交组合成9个处理，研究其对赤杨叶容器苗生长和质量的影响，运用隶属函数法进行综合评价。[结果]3种因素中，基质配比与对赤杨叶容器苗苗高、高径比的影响显著(P<0.05)，对地径的影响不具显著性(P>0.05)。容器规格、缓释肥量对赤杨叶容器苗地径、苗高、高径比的影响均不显著(P>0.05)。基质理化性质中，PH值、有机质含量、水解氮、容重与容器苗苗高、高径比均为显著相关，总孔隙度与苗高呈显著相关，有效磷含量与高径比相关性显著。隶属函数综合评价表明:容器规格 A 2(10.0 cm×13.5 cm)、基质配比 B2(椰糠4:泥炭4:土2)、缓释肥用量 C3(4 kg/m3)，综合排名第一。[结论]容器规格、基质配比和缓释肥用量单一或交互影响赤杨叶容器苗的生长，隶属综合排名前列的组合方案可在赤杨叶容器育苗生产上加以应用。研究结果为赤杨叶容器育苗技术提供了科学依据，丰富了赤杨叶幼苗培育方法。
[Objective]By studying the effects of factors such as seedling substrate ratio,slow-release fertilizer dosage,container specifications,and their combinations on the growth and quality of 2-year-old Alniphyllum fortunei container seedlings,this study explores the differences in growth effects of red poplar leaf container seedlings in different combinations,selects the optimal seedling cultivation plan,and provides reference for cultivating high-quality red poplar leaf container seedlings.[Method]Using Alniphyllum fortunei seedlings as materials,a factorial experimental design was adopted,with three container specifications,three substrate ratios,and three slow-release fertilizer dosages set up.Nine orthogonal combinations were used to study their effects on the growth and quality of red poplar leaf container seedlings.The membership function method was used for comprehensive evaluation.[Result]Among the three factors,the substrate ratio had a significant impact on the height and height to diameter ratio of container seedlings of Populus euphratica(P<0.05),but had no significant impact on the ground diameter(P>0.05).In the physical and chemical properties of the substrate,pH value,organic matter content,hydrolyzed nitrogen,bulk density are significantly correlated with container seedling height and height to diameter ratio.The total porosity is significantly correlated with seedling height,while the effective phosphorus content is significantly correlated with height to diameter ratio.The comprehensive evaluation of the membership function shows that the container size A2(10.0 cm x 13.5 cm),substrate ratio B2(coconut bran 4:peat 4:soil 2),and slow-release fertilizer dosage C3(4 kg/m3)rank first comprehensively.[Conclusion]The combination of container specifications,substrate ratio,and slow-release fertilizer dosage can have a single or interactive impact on the growth of container seedlings of Alniphyllum fortunei,and can be applied in the production of container seedlings of Alniphyllum fortunei,which belongs to the top comprehensive ranking.The research results provide a scientific basis for the container seedling cultivation technology of Alniphyllum fortunei and enrich the cultivation methods of Alniphyllum fortunei seedlings.
