摘　　要：对不同配比的泥炭-谷壳基质、不同规格容器、不同缓释肥用量及是否进行空气切根对1年红豆树容器苗生长的影响进行系统研究。结果表明:若谷壳与泥炭的比例不高于5∶5,基质配比对红豆树1年生容器苗生长影响不明显,而缓释肥用量、容器规格及空气切根与否则对红豆树1年生容器苗的苗高和地径生长影响显著,通过空气切根苗高可提高10%,地径提高9.3%。综合考虑生产成本,1年生红豆树优化的容器育苗方案为:泥炭-谷壳基质配比为5∶5,无纺布容器规格为4.5 cm×10 cm,基质中施用缓释肥量为2.0 kg/m3,同时进行空气切根处理。An experiment was conducted to investigate the effects of substrate composition,container size,slow release fertilizers,air cutting roots on the growth of one year-old Ormosia hosiei seedlings.The results showed that the substrate composition had no significant influence on the growth of seedlings when the ratio of peat to hull was below 5∶5,while the container size,the slow release fertilizers,and the air cutting roots had significant differences on the height and ground diameter of one year-old O.hosiei container seedlings.With the treatment of cutting roots,the height of one year-old O.hosiei container seedlings was increased by 10% and the ground diameter increased by 9.3%,compared with control.Considered the production cost,the scheme that included substrate composition with peat-hull=5∶5,4.5×10 cm of non-woven fabric container,2.0 kg/m3 of slow release fertilizers and cutting roots was suitable for container seedlings of O.hosiei.
