Comprehensive evaluation using the membership function method revealed that the combination of matrix ratio matrix ratio,matrix ratioA6[V(coconut bran):V(peat): V(soil)=1:1:0] with slow release fertilizer B3 (3kg/m3) and container size C3( 12.5cm×16.0cm )was better. The A6B3C3 combination resulted in a seedling height,ground diameter and height-to-diameter ratio of 115.73cm 12.82mm and 93.52,respectively,while the A5B3C3 combination resulted inthevaluesof 126.17cm 12.20mm and107.57,respectively.Theplantingdensityof T. sinensis container seedlings is 100/m2 ,andthe growthrate is thebest.【Conclusion】The matrixratio,slow-releasefertilizerdosageandcontainersizeinteractonthe growth of T. sinensis container seedlings.The A6B3C3 and A5B3C3 combinationswith a seedling density of 100/m2 can use in container seedling production of T. sinensis,providing a scientific basis for improving the quality of T. sinensis seedlings and optimizing seedling technology.

香椿Toonasinensis是楝科Meliaceae香椿属Toona的落叶乔木,主要分布于我国长江南北区域。其木材纹理优美且结构细致,素有“中国桃花心木”之称,常用作家具的制作。由于良好的加工性能与耐腐蚀性,香椿木材适合雕刻和制作各种工艺品,深受木工和手工艺爱好者的喜爱[。作为珍贵的速生造林树种,香椿是国家储备林建设的首选树种之一,致力于生态保护和林业产业发展[2]。此外,其嫩芽被誉为“树上蔬菜”,香味浓郁、营养丰富,是传统美食中的珍品[3]。然而,目前香椿良种化水平较低,苗木质量较差,无法满足日益增长的生产需求[4]。现有的香椿苗木在品种纯度、生长一致性等方面存在不足,制约了其大规模种植和产业化进程[5-]。因此,探讨和优化香椿育苗技术,提高苗木质量,成为提升香椿产业可持续发展的关键所在。
近年来,容器育苗具有便于生产、育苗周期短、成活率高、延长造林季节等优势,被广泛运用于各树种优质苗木的培育[7-9]。其成功应用离不开多个因素的综合作用,包括培养基质、施肥方案、容器规格及密度摆放等。优质的培养基质具有良好的通气性、保水性和保肥性,以提供植物所需的养分,促进根系的生长与发育[10]。科学合理的施肥方案能够满足苗木生长的养分需求,提高其抗逆性和生长速度[]。同时,适宜的容器规格能够提供良好的生长环境,促进根系的伸展和生长,有利于苗木的健康发育[12]。另外,在容器育苗过程中,苗木的摆放密度也对其生长和发育具有显著影响。……
