笔者在木犀科白蜡属与丁香属之间进行白蜡树与紫丁香的高杆劈接试验,平均嫁接成活率为88.8%,最高达96.4%,嫁接后经济效益明显提高。通过生长指标与接口径级的方差分析,表明这些指标是白蜡树高接紫丁香的关键因素;各生长指标的多重比较分析,表明苗高123.10 cm,地径3.75 cm,接口粗度2.43 cm以上的白蜡树是质量最佳的砧木,且当年紫丁香的分枝量可以增加到4.7条,达到市场对嫁接苗树形饱满度的要求;紫丁香的树冠分枝量与白蜡树的接口粗度和地径之间存在幂函数Yi=A+XBi的回归关系,其相关系数为0.911和0.925,相关性显著,可靠性高达0.999.旨在为白蜡和紫丁香的推广拓展了更大的分布空间。
筆者在木犀科白蠟屬與丁香屬之間進行白蠟樹與紫丁香的高桿劈接試驗,平均嫁接成活率為88.8%,最高達96.4%,嫁接後經濟效益明顯提高。通過生長指標與接口徑級的方差分析,錶明這些指標是白蠟樹高接紫丁香的關鍵因素;各生長指標的多重比較分析,錶明苗高123.10 cm,地徑3.75 cm,接口粗度2.43 cm以上的白蠟樹是質量最佳的砧木,且噹年紫丁香的分枝量可以增加到4.7條,達到市場對嫁接苗樹形飽滿度的要求;紫丁香的樹冠分枝量與白蠟樹的接口粗度和地徑之間存在冪函數Yi=A+XBi的迴歸關繫,其相關繫數為0.911和0.925,相關性顯著,可靠性高達0.999.旨在為白蠟和紫丁香的推廣拓展瞭更大的分佈空間。

The author did taller stem cleft grafting experiment of Fraxinus chinensis and Syringa oblata of Oleaceae ,average grafting survival rate was 88.8%,the maximum 96.4%,whose economic benefit increased after grafting .Variance analysis of growth index and interface diameter class showed that these indexes were key factors of grafting of Fraxinus chinensis and Syringa oblata; multiple comparison analysis of growth indexes showed that Fraxinus chinensis of seedling height 123.10 cm, ground diameter 3.75 cm, interface diameter above 2.43 cm was the best quality stock and branch number in-creased to 4.7 in current year ,which reached to the market plumpness need of grafting seedling;crown branches of Syringa oblata were regression relationship of Yi =A+XBi with interface diameter and ground diameter of Fraxinus chinensis, whose correlation coefficient was 0.911 and 0.925, significant correlation , reliability 0.999.The experiment expended more dis-tributed space of promotion of Fraxinus chinensis and Syringa oblata.
