摘要:
 以美国红枫改良品种（Acer×freemanii ‘Autumn Blaze’）为试验材料，剪取1年生枝条的中上部做插穗，用ABT1#1 000 mg/L溶液处理插穗，分别扦插在河砂、珍珠岩、蛭石、草炭、炉灰渣、珍珠岩+蛭石、珍珠岩+蛭石+草炭7种不同基质上。选取生根促进剂ABT1#、IBA、NAA以及IBA+NAA的混合溶液分别设计500、1 000、1 500 mg·L-1和2 000 mg·L-1 4个浓度梯度处理插穗，以清水处理作为对照组。结果表明，蛭石与珍珠岩的混合基质为最佳基质，扦插在该基质上的插穗生根率可达到87.3%，平均根数为9.8条，平均根长为7.6 cm，根系效果指数为0.83。用生根促进剂ABT1#1 000 mg·L-1、ABT1# 2 000 mg·L-1和IBA+NAA 1 000 mg·L-1处理红枫插穗，生根率分别达到57.8%、58.9%和60.0%，根系效果指数分别达到1.00、1.17和0.71。IBA500 mg/L处理的插穗，生根率为68.9%，但平均根数较少，不适合美国红枫的扦插生根。
Abstract:
 Cuttings from the upper parts of the branches from one-year-old seedlings of Acer×freemanii “Autumn Blaze” were adopted to carry out propagation experiment. After the cuttings were treated with root promoting chemicals, they were raised in different substrates. The results showed that perlite + vermiculite was the best soil substrate, in which the rooting rate reached 87.3%, the average root number, length, and root effect index were 9.8, 7.6 cm, and 0.83, respectively. The suitable root promotion reagent were ABT No. 1 with concentrations of 1 000 mg·L-1 and 2 000 mg·L-1 respectively, and IBA + NAA (1 000 mg·L-1), under which the rooting rates were 57.8%, 58.9%, and 60.0%, the root effect indices reached 1.00, 1.17, and 0.71. respectively. Although in IBA (500 mg·L-1) treated group, the rooting rate was as high as 68.9%, the average number of roots were less, it was not suited for cuttings.
