摘要: 通过不同生根培养基、炼苗预处理、移栽基质以及叶面施肥等对金桂品种微繁苗炼苗的影响开展试验研究,为目标品种的壮苗快繁提供炼苗的技术支撑。通过对金桂快速繁殖关键技术研究,结果表明,金桂微繁苗生根率和生根数的最佳处理组合为A3B2C3,即B5基本培养基+2 mg·L-1 NAA+0.10 mg·L-1 6-BA,其生根率、平均生根数分别为:91.11%、3.83条/株。炼苗的最佳处理组合为A3B2C3,即以苗圃土:珍珠岩:腐殖土=2:3:7为炼苗基质,金桂微繁苗炼苗的成活率和苗木增长率分别达到82.2%、42.2%。

Abstract: We studied the effects of different rooting media, pre-treatment of seedling cultivation, transplanting matrix and leaf surface fertilization on the seedling cultivation of micro-propagation of Osmanthus fragrans to provide technical support for the rapid propagation of strong seedlings of target varieties, and the key technology of rapid propagation of O.fragrans. The optimal combination of rooting rate and rooting number of micro-propagated O.fragrans seedlings was A3B2C3, the rooting rate and average rooting number of B5 basic medium+2 mg·L-1 NAA+0.10 mg·L-1 6-BA were 91.11% and 3.83 pieces/plant, respectively. A3B2C3 is the optimal combination for seedling refining, that is, when the nursery soil:perlite:humus=2:3:7 was used as the seedling refining matrix, the survival rate and growth rate of micropropagation seedlings of O.fragrans reached 82.2% and 42.2%, respectively.
