摘　　要：以园土(A)、蚯蚓粪肥(B)、枝叶粉碎物堆肥(C)和碎木片(D)为基质成分,采用L 9(34)正交试验设计对青冈(Cyclobalanopsis glauca(Thunb.)Oerst.)和小叶青冈(C.myrsinaefolia(Bl.)Oerst.)3年生容器苗的根系发育相关指标进行了测定和比较。结果表明:总体来看,V(A)∶V(B)∶V(C)∶V(D)=1∶2∶2∶1混配基质中青冈以及V(A)∶V(B)∶V(C)∶V(D)=1∶4∶4∶2和V(A)∶V(B)∶V(C)∶V(D)=3∶2∶4∶0混配基质中小叶青冈的根系发育指标均较好。碎木片对2种植物根系综合评价指数的影响最大;理论上适宜青冈和小叶青冈根系发育的混配基质分别为V(A)∶V(B)∶V(C)∶V(D)=3∶4∶2∶1和V(A)∶V(B)∶V(C)∶V(D)=3∶2∶2∶1。Taking garden soil(A),earthworm manure(B),branch and leaf crushing compost(C),and wood chip(D)as substrate components,the related indexes of root development of three-year-old container seedlings of Cyclobalanopsis glauca(Thunb.)Oerst.and C.myrsinaefolia(Bl.)Oerst.were determinated and compared by using L 9(34)orthogonal test design.The results show that the root development indexes of C.glauca in V(A)∶V(B)∶V(C)∶V(D)=1∶2∶2∶1 mixed substrate and C.myrsinaefolia in V(A)∶V(B)∶V(C)∶V(D)=1∶4∶4∶2 and V(A)∶V(B)∶V(C)∶V(D)=3∶2∶4∶0 mixed substrates are relatively good in general.Wood chip has the greatest influence on root comprehensive evaluation indexes of the two species,and the theoretically suitable mixed substrates for root development of C.glauca and C.myrsinaefolia are V(A)∶V(B)∶V(C)∶V(D)=3∶4∶2∶1 and V(A)∶V(B)∶V(C)∶V(D)=3∶2∶2∶1,respectively.
