三花冬青嫩枝扦插繁殖技术

Studies on Softwood Cuttage Propagation Technique of Ilex triflora Bl.

运用单因素试验研究植物生长调节剂、扦插基质和带踵扦插等因素对三花冬青扦插生根的影响,结果表明3个因素对三花冬青扦插生根影响差异显著,采用当年生半木质化插条,黄心土为基质,IAA 250 mg·L-1或IBA 500 mg·L-1蘸根处理15 s,带踵扦插等技术措施,可以显著提高三花冬青嫩枝扦插的生根率,在生产中具有较高的应用价值。

Using the single factor experiment to study the effect of plant growth regulating substances, cutting materials, cutting with heel and other factors on llex triflora B1. cutting and rootage, the results showed the three factors had great effects on cutting survival of Ilex triflora BL ,in the experimental conditions ,including using half lignified cuttings in the same year,and yellow soil as materi- als ,250 mg L-1 of IAA or 500 mg L-1 of IBA dipping treatment for 15s, cutting with heel and other technical measures, it might significantly improve the cuttings rooting rate of Ilex triflora B1. ,which was of high practical value in the production.
