摘　　要：为了培养娜塔栎富根壮苗,提高娜塔栎移载造林成活率,采用完全随机区组设计,以娜塔栎1年生苗出现测苗为观测对象,每个试验处理观测30株/重复,3次重复,共90株苗。观测调查指标包括苗高和地径。结果表明:娜塔栎容器育苗基质最佳配方为泥炭土∶黄心土∶钙镁磷肥=60∶35∶5。娜塔栎大田育苗不同浓度GGR6对苗木进行叶面喷施处理后,其苗木根长大于5 cmⅠ级侧根数、苗高生长、地径生长均有明显差异,宜采用100 mg/L GGR6喷施叶面,相比对照,娜塔栎苗木根长大于5 cmⅠ级侧根数增加60%以上,苗高生长增加20%以上,地径生长增加15%以上。The study was carried out to seedling randomized block design. 1-year-old seedlings of strengthening experiment for Quercus nuttallii. In this trial, completely Q. nuttallii provenances were observed and investigated in 30 seedlings per replicate, with 3 replicates, 90 seedlings in total. Investigation indicators include seedling height and ground diameter. The results showed as follows： The optimum formula of matrix for container nursery of Q. nuttallii was peat soil ： yellow subsoil ： Ca-Mg-P fertilizer=60 ： 35 ： 5. After spraying GGR6 on Q. nuttallii seeding leaves in field with different concentrations, there were significant differences in number of Grade 1 lateral root with length larger than 5 cm, seedling height growth and ground diameter growth. The measure of spraying 100mg/L GGR6 on leaves could be taken, which could increase 60% of the number of Grade 1 lateral root with length larger than 5cm, 20% of seedling height growth, 15% of ground diameter growth by comparing with the control.
