摘　　要：为筛选出适合毛乌素沙地栽培的榛子优良品种,从辽宁省章古台引进5个大果榛子品种(‘达维’、‘辽榛3号’、‘辽榛7号’、‘辽榛8号’和‘平欧15号’),在原陕西省治沙研究所红石峡植物园和靖边县牛玉琴全国治沙基地2个试验地开展引种栽培试验及生长规律研究,并对其物候期、生长情况和结实情况等指标进行观测分析研究。结果表明:5个大果榛子品种在2个试验地均能正常生长发育,完成营养生长和生殖生长。但从树高和冠幅指标看,其中‘达维’和‘辽榛3号’显著优于‘辽榛7号’和‘辽榛8号’(P<0.05);从新梢长度、新梢粗度和新梢数量指标看,‘达维’显著优于其他3个树种(P<0.05),其次为‘辽榛3号’;从结实指标看,除‘平欧15号’性状较其他品种差,其余4个树种间无明显差异(P>0.05);从结实日期看,‘达维’和‘辽榛3号’早于‘辽榛7号’和‘辽榛8号’,这4个引种品种均显著优于‘平欧15号’。综合生长指标和结实指标看,5个树种都可在榆林引种种植,但‘达维’和‘辽榛3号’更适宜在毛乌素沙地推广种植,‘平欧15号’生长表现最差,不适宜在毛乌素沙地推广栽培。To screen out good hazelnut varieties suitable for cultivation in Mu Us sandy land,five major hazelnut varieties‘Dawei’,‘Liaozhen 3’,‘Liaozhen 7’,‘Liaozhen 8’and‘Pingou 15’were introduced from Zhanggutai,Liaoning Province.Two experiments were conducted in Hongshixia Botanical Garden of Shaanxi Sand Control Research Institute and Niuyuqin National Sand Control Base of Jingbian County.Experiments on introduction and cultivation were carried out,and the phenological period,growth and fruiting conditions were observed and analyzed.The results showed that the five hazelnut varieties could grow normally and complete vegetative and reproductive growth in the two experimental sites.But in terms of tree height and crown diameter,‘Dawei’and‘Liaozhen 3’were significantly better than‘Liaozhen 7’and‘Liaozhen 8’(P<0.05).In terms of shoot length,shoot diameter and shoot number,‘Dawei’was significantly better than the other three varieties(P<0.05),followed by‘Liaozhen 3’.From the perspective of seed setting index,there was no significant difference(P>0.05)among the four varieties except‘Pingou 15’,which was worse than other varieties.From the perspective of seed setting date,‘Dawei’and‘Liaozhen 3’were earlier than‘Liaozhen 7’and‘Liaozhen 8’,which were significantly better than‘Pingou 15’.According to the comprehensive growth index and fruiting index,the five varieties can be introduced and planted in Yulin,but‘Dawei’and‘Liaozhen 3’are more suitable to be popularized and planted in Mu Us sandy land,‘Pingou 15’has the worst growth performance and is not suitable to be popularized and cultivated in Mu Us sandy land.
