Effects of container size,matrix ratio and slow-release fer tilizer on the growth and quality of Toona sinensis container seedlings
[目的]研究基质配比、缓释肥用量和容器规格三种因素对香椿(Toona sinensis)容器苗生长与质量的影响，以优化香椿育苗技术，提高苗木质量，满足其大规模种植和产业化需求。[方法]采用析因试验设计，设置6种基质配比、3种缓释肥用量和 3 种容器规格，组合成 27个处理，分析香椿苗高、地径及高径比。采用隶属函数法对各育苗组合的效果进行综合评价。[结果]基质配比和缓释肥用量对香椿容器苗苗高和地径的影响均达到极显著水平(P<0.01)，容器规格对地径和高径比的影响分别达到显著(P<0.05)和极显著水平(P<0.01)。双因素交互作用中，基质配比×容器规格、基质配比×缓释肥量、容器规格×缓释肥量对香椿容器苗苗高的影响达到极显著(P<0.01)。三因素交互作用中，基质配比×容器规格×缓释肥量对香椿容器苗苗高、地径、高径比的影响均达到极显著(P<0.01)。对香椿幼苗生长的影响因素表现为:缓释肥量>容器规格>基质配比。隶属函数综合评价表明:基质配比A6(椰糠:泥炭:土=1:1:0)、A5(椰糠:泥炭:土=1:2:1)与缓释肥用量B3(3 kg/m3)以及容器规格C3(12.5 cm×16.0 cm)的组合效果较好，A6B3C3组合的苗高、地径、高径比分别为115.73 cm、12.82 mm和 93.52;A5B3C3组合的苗高、地径、高径比分别为 126.17 cm、12.20 mm和 107.57。[结论]基质配比、缓释肥用量、容器规格交互影响香椿容器苗的生长。隶属综合排名前列的组合方案可在香椿容器育苗生产上加以应用。研究结果为优化香椿育苗技术提供了科学依据，可促进香椿产业的可持续发展。
[Objective]to study the effects of substrate ratio,slow-release fertilizer dosage and container size on the growth and quality of container seedlings of T.sinensis,in order to optimize the seedling raising technology,improve the seedling quality and meet the needs of large-scale planting and industrialization.[Method]using factorial experimental design,6 kinds of matrix ratio,3 kinds of slow-release fertilizer dosage and 3 kinds of container specifications were combined into 27 treatments,and the height,ground diameter and height-diameter ratio of T.sinensis seedlings were analyzed.The effect of each seedling combination was evaluated comprehensively by the method of membership function.[Result]the effects of matrix ratio and slow-release fertilizer on seedling height and ground diameter of T.sinensis container seedlings were extremely significant(P<0.01).The effects of container size on ground diameter and height-diameter ratio were significant(P<0.05)and extremely significant(P<0.01),respectively.In the interaction of two factors,the effects of matrix ratio×container size,matrix ratio×slow release fertilizer amount and container size×slow release fertilizer amount on the seedling height of T.sinensis container seedlings were very significant(P<0.01).In the interaction of the three factors,the matrix ratio×container size×slow release fertilizer had significant effects on the height,ground diameter and height-diameter ratio of T.sinensis container seedlings(P<0.01).The factors affecting the growth of T.sinensis seedlings were as follows:slow release fertilizer amount>container specification>substrate ratio.The comprehensive evaluation of membership function showed that the combination of substrate ratio A6(coconut bran:peat:soil=1:1:0),A5(coconut bran:peat:soil=1:2:1),slow release fertilizer B3(3kg/m3)and container specification C3(12.5 cm×16.0 cm)was better.The seedling height,ground diameter and height-diameter ratio of A6B3C3 were 115.73 cm,12.82 mm and 93.52,respectively.The seedling height,ground diameter and height-diameter ratio of A5B3C3 combination were 126.17 cm,12.20 mm and 107.57,respectively.[Conclusion]the ratio of matrix,the amount of slow-release fertilizer and container specification interact on the growth of T.sinensis container seedlings.The combination scheme which belongs to the top of the comprehensive ranking can be applied in the container seedling production of T.sinensis.The research results provide a scientific basis for optimizing the seedling raising technology of T.sinensis and can promote the sustainable development of T.sinensis industry.
