摘　　要：为丰富宁夏银北盐渍化严重地区造林树种,提高造林效益,自2017年始,平罗县林业技术推广服务中心从山东省东营市东营区六户镇六户林场引进鲁蜡5号种条1000根,用本地洋白蜡做砧木,采用劈接嫁接方法进行嫁接繁殖试验,通过2年(2017—2018年)的驯化繁育,培育种苗3500余株。观测结果表明:该树种能够适应本地气候,生长量显著大于本地白蜡(洋白蜡),树干通直,树冠窄,树姿优美,有扩繁和栽培价值。In order to enhance afforestation species in serious saline-alkali area in northern Yinchuan of Ningxia and improve the benefits, Pingluo County Service Center for Introducing Forestry Technology has introduced 1 000 races of Lula No.5 from Liuhu Forestry Center, Liuhu Town, Dongying District, Dongying City, Shandong Province since 2017. The local Fraxinus pennsylvanica Marsh. was used as the rootstock, and the cleft grafting method was adopted for grafting and reproduction tests. About 3 500 seedlings were cultivated between 2017 and 2018. The observation and analysis results showed that Lula No.5 could adapt to local climate, and the growth was significantly larger than that of local Fraxinus pennsylvanica Marsh.. It has the values for reproduction and cultivation with straight stem, narrow crown and graceful tree performance.
