为探讨金叶复叶槭嫩枝扦插的最佳扦插基质和扦插设施，通过设置3 种基质：河沙、珍珠岩和混合基质（珍珠岩:泥炭=1:1），以及2 种扦插设施：大棚遮光扦插和大棚套小棚扦插，进行扦插效果对比试验研究。结果表明：大棚遮光扦插设施中，珍珠岩和混合基质优于河沙。其中，珍珠岩处理生根率最高，达95.6%，根数最多，根粗而短，根系活力也较高。而混合基质处理根系发育较好，根系活力最大，根细而长，但生根率较低，为78.4%。采用混合基质时，大棚遮光扦插设施中，高温高湿时扦插，与低温低湿时相比，其生根率和根系活力显著降低，根数明显减少。但在大棚套小棚扦插设施中，两扦插时间插穗生根指标及幼苗生长指标均无显著差异。因此，针对大棚遮光扦插设施，纯珍珠岩是最理想的扦插基质，且扦插时间范围较大。若使用混合基质，大棚遮光扦插设施适合低温低湿下扦插，而大棚套小棚扦插设施在高温高湿时扦插也能保持较高的生根率。

In order to make an optimal selection of substrate and cutting facilities, the tender branch cutting experiments of Acer negundo ‘Auratum’ were carried out with three kinds of culture substrates of sand, perlite, mixed substrates (perlite : turf=1:1), and two kinds of cutting facilities of the plastic awning facilities and the double layer greenhouse culture seedling facilities. The results showed that perlite and mixed substrates treatments were both better than sand treatment. Among the three treatments, perlite was the highest in rooting rate of 95.6% and root number with characters of crude and short, and the higher in root activity. Mixed substrates treatment was the higher in root activity with thin and long root, but was low as 78.4% in the rooting rate. Under the plastic awning facilities with the mixed substrates, compared with the low temperature and low humidity environment, the rooting rate, root activity, and root number were decreased significantly in higher temperature and humidity. However, the rooting indexes and the seedling growth indexes showed no difference between the two different cutting times under the double layer greenhouse culture seedling facilities. Pure perlite was the optimal culture substrate with long range of cuttings time in plastic awning facilities. Under the low temperature and humidity condition, the mixed substrates were suitable for tender branch cuttings under the plastic awning facilities. However, tender branch cuttings with the double layer greenhouse culture seedling facilities still could maintain a high rooting rate under the high temperature and humidity condition.
