摘要:以山东省经济林研究所试验地5年生杂交榛Corylus heterophylla × C. avellana ‘85?鄄134’和欧洲榛C. avellan‘Barcelona’为对象，于2007年3 - 7月在山东农业大学温室进行扦插试验，对影响杂交榛‘85-134’和欧洲榛‘Barcelona’扦插生根的关键技术进行了系统研究。结果表明：①杂交榛‘85?鄄134’和欧洲榛‘Barcelona’均适于进行嫩枝扦插，以7月初为最佳扦插时期，杂交榛‘85-134’和欧洲榛‘Barcelona’生根率分别达到71.1%和81.1%，插穗平均根数分别达到10.3根和11.7根，都极显著的优于其他3个时期。 ② 在山东泰安地区，杂交榛‘85-134’和欧洲榛‘Barcelona’基部萌条生根率分别为43.3%和45.6%，生根效果不及树冠枝条。③植物生长调节物质对杂交榛‘85-134’和欧洲榛扦插生根均有一定促进作用，其中以100 mg·L－1吲哚丁酸（IBA）溶液浸泡2 h促根效果最佳。④以珍珠岩∶蛭石 = 2 ∶ 1（体积比）为扦插基质，其液气固三相比最理想，有利于插穗生根。表6参13

Abstract:In order to enhance the rooting rate of hazelnut cuttings，analysis how different periods，sources of cuttings，plant growth regulator and cutting substrate affect rooting，and find the best combination of technical support for hazelnut cuttings root，the author used five-year-old Corylus heterophylla × C. avellana ‘85-134’and C. avellana‘Barcelona’collected from the Institute of Economic Forestry in Shandong Province as experimental material，carried out the cutting experiments in the greenhouse of Shandong Agricultural University from March to July 2007. Complete randomized block design was designed in experiment，in which the author researched four periods（March 20th，June 1th，June 15th，July 5th），four types of plant growth regulators（indole-3-butyric acid （IBA），1 IBA + 1 naphthaleneacetic acid（NAA），ABT1，NAA） and control （ck），two sources of cuttings（canopy shoots and basal shoots），three types of substrate （the perlite and vermiculite with a volume ratio of 2 ∶ 1，1 ∶ 1 and the sand）. Results showed that 1） C. heterophylla × C. avellana‘85-134’and C. avellana‘Barcelona’were both suitable for softwood cuttings with the best cutting time on July 5th. The rooting rate for‘85-134’was 71.1% with the average number of root amounted to 10.3 whereas‘Barcelona’was 81.1% with the average number of root amounted to 11.7；these were significantly better（P＜0.01） than the other three periods （March 20th，June 1th，June 15th）. 2） Compared with canopy shoots，the rooting rate of basal shoots was significantly less for‘85-134’ （P＜0.05）（43.3%） and for ‘Barcelona’（P＜0.01）（45.6%）. 3）Plant growth regulators promoted rooting rates of ‘85-134’and‘Barcelona’in the following order：100 mg·L－1IBA＞ 50 mg·L－1IBA + 50 mg·L－1NAA＞ 100 mg·L－1ABT1 ＞ 100 mg·L－1NAA ＞ ck. 4） The most favorable cutting substrate to achieve the best rooting rate was perlite and vermiculite with a volume ratio of 2 ∶ 1 as the ratio of liquid，gas，and solid was ideal. So that was the most conducive to choose the canopy shoots，with the best being IBA at 100 mg·L－1 with a 2 h immersion cutting in the perlite and vermiculite with a volume ratio of 2 ∶ 1 in early July in Taian region. ［Ch，6 tab. 13 ref.］
