通过对湿地松扦插基质、生长调节剂的筛选和对不同年龄母树、不同规格插穗的生根效果研究,结果表明：粉剂1、粉剂2和100mg/L IBA扦插前处理平均生根率较高,达到70%左右,100mg/L911处理的插穗根系质量最好;泥炭：珍珠岩=5：5的基质配方平均生根率最高,且与其他配方存在显著差异,生根质量差异不显著;2a和3a生母株上采集的插穗生根率和生根质量均比6a生好;插穗基径和针叶长度与生根效果存在显著的正相关关系,控制针叶长度在3.1~7.0cm之间,并选择粗壮的插穗进行扦插效果更好。
通過對濕地鬆扢插基質、生長調節劑的篩選和對不同年齡母樹、不同規格插穗的生根效果研究,結果錶明：粉劑1、粉劑2和100mg/L IBA扢插前處理平均生根率較高,達到70%左右,100mg/L911處理的插穗根繫質量最好;泥炭：珍珠巖=5：5的基質配方平均生根率最高,且與其他配方存在顯著差異,生根質量差異不顯著;2a和3a生母株上採集的插穗生根率和生根質量均比6a生好;插穗基徑和針葉長度與生根效果存在顯著的正相關關繫,控製針葉長度在3.1~7.0cm之間,併選擇粗壯的插穗進行扢插效果更好。

The rooting effects of different cutting substrates,growth regulators,age of seed-tree and grades of cuttings of the Pinus elliottii Engelm.stem was studied.The results showed that the rooting rate of pretreatments with dustable power（DP）1#,DP2# and 100 mg/L IBA was higher than others and reached 70% more or less.The rooting quality of pretreatments with 100 mg/L 911 was the best.There were significant differences in different substrates in rooting rate but no significant differences in rooting quality.The rooting rate was highest when the ratio of peat and perlite was 5：5.Stem cuttings of two and three year old seed-tree were better than stem cuttings of six year old seed-tree not in rooting rate but in rooting quality.Rooting quality had a significant positive correlation with thickness and needle length of stem cuttings.Rooting effects were better when used more thickness stem cutting and needle length within 3.1 to 7.0 centimeters.
