摘　　要：以筇竹实生苗为研究对象,采用正交试验设计,系统研究不同容器材质、容器规格与缓释基肥施入量3个试验因子对1年生筇竹容器苗生长的影响。结果表明:选用无纺布袋、规格10 cm×14 cm、缓释基肥2 kg/m^3进行筇竹轻基质容器育苗处理,地径和苗高分别为0.33 cm和40.50 cm,分别比最差处理高61.90%和23.76%;分蘖数为8.20,比最差处理高95.23%;根长和一级根数分别为21.06 cm和28.80根;生物量为15.01 g,且根的生物量分配比例显著增大;生理指标总N含量和Chl含量分别为2.94 mg/g和33.38 mg/g;苗木质量指数最高。因此,该处理为1年生筇竹轻基质容器育苗的最优选择。In this study, Qiongzhuea tumidinoda seedlings were chosen as the research objects. The effects on annual container seedling growth with 3 test factors including different container material, different container specification and different amount of slow release base fertilizer were systematic analyzed by orthogonal design method. The results showed that the light matrix container seedling with the treatment of 10 cm × 14 cm non-woven bags and 2 kg/m3 slow release fertilizer. Stem diameter and seedlings height were 0. 33 cm and 40.50 cm and 61.90% and 23.76% higher than the worst one, respectively. Tiller number was 8.20, 95.23% above the worst treatment one. The root length and the number of first order roots were 21.06 cm and 28.80, respectively. The seedlings biomass was 15.01 g, and the allocation ratio of root biomass was significantly increased. Nitrogen content and Chlorophyll content were 2. 94 mg/g and 33.38 mg/g, respectively. It was the highest seedling quality index. Accordingly, the treatment in this study was the best choice for annual seedlings of Qiongzhuea tumidinoda under light matrix container nursery.
