摘　　要：对山西省古交市常安乡龙庄沟村大果榛子栽培基地的5个大果榛子品种进行1 a的野外观测试验,通过生长指标、产量指标、物候期等分析其引种适应性。结果表明,5个大果榛子品种生长规律较一致,以苗高增加量、地径增加量、单株果实产量、抽稍情况为指标进行适应性评价,初步确定辽榛7号、达维、平欧15号更能适应试验区的立地条件。根据果实大小和空壳率可知,辽榛7号、达维果壳较小,但果实更为饱满;辽榛8号、平欧15号果壳较大,但果仁饱满度较差。从果实口感来看,辽榛8号、玉坠更佳。根据花期不同,可以将达维、辽榛8号、玉坠设置为相互授粉品种,将辽榛7号和平欧15号设置为相互授粉品种。A 1-year field observation experiment was conducted on 5 varieties of hazelnuts in Longzhuanggou Village of Changan Township of Gujiao City in Shanxi Province.The introduction adaptability was analyzed through growth indicators,yield indicators,phenological periods and other factors.The results showed that the growth patterns of the 5 hazelnut varieties were relatively consistent.The adaptability evaluation was conducted based on the indicators of seedling height increase,ground diameter increase,single plant fruit yield and pruning situation.It was preliminarily determined that Liaozhen 7,Dawei and Pingou 15 were more suitable for the site conditions in the experimental area.According to the size of the fruit and the percentage of empty shells,it could be seen that Liaozhen 7 and Dawei had smaller shells but fuller fruitsfruit.Liaozhen 8 and Pingou 15 had larger fruit shells,but their kernels had poor plumpness.From the perspective of fruit taste,Liaozhen 8 and Yuzhui were better.According to different flowering periods,Dawei,Liaozhen 8 and Yuzhui could be set as mutually pollinating varieties,while Liaozhen 7 and Pingou 15 could be set as mutually pollinating varieties.
