摘　　要：以Pawnee(波尼)、YLC10和YLC21等10个薄壳山核桃优良品系为试材,在山东省青岛市进行引种适应性评价试验,结果表明,薄壳山核桃在青岛市西海岸新区种植普遍表现生长良好,不同品系(种)间树体生长、结果及果实性状方面存在着明显差异。采用隶属函数法综合分析评价,YLC29、YLC13、YLC12、YLC21生长势旺盛,顶端优势明显、树干直、增粗快,7年生树高分别为7.77 m、7.70 m、8.03 m和7.30 m,基径分别为19.0 cm、17.83 cm、17.33 cm和18.0 cm;Pawnee、YLJ42、YLC21、YLC23、YLC13结果较好,表现为结果多、坚果品质优,平均株产坚果分别为1.82 kg、0.50 kg、0.92 kg、0.32 kg、0.29 kg,果仁脂肪和蛋白质含量分别为74.60%、68.4%、71.0%、73.4%、72%和10.40%、11.00%、12.70%、12.20%、8.41%。综合评价分析Pawnee、YLJ42、YLC23为较好的果用品种,YLC21、YLC13为果材兼用品种,YLC29、YLC12为较好的生态储备林品种。Ten excellent strains of Carya illinoensis,such as Pawnee(Boni),YLC10 and YLC21,were used as test materials,and the introduction adaptability of Carya illinoensis was evaluated in Qingdao,Shandong Province.The results showed that Carya illinoensis generally grew well in the west coast new district of Qingdao,and there were obvious differences in tree growth,fruit bearing and fruit characters among different strains(species).The membership function method was used to comprehensively analyze and evaluate the growth vigor of YLC29,YLC13,YLC12 and YLC21,with obvious apical dominance,straight trunk and fast thickening.The height of 7-year-old trees was 7.77 m,7.70 m,8.03m and 7.30m respectively,and the basal diameters were 19.0 cm,17.83 cm,17.33cm and 18.0 cm,respectively.Pawnee,YLJ42,YLC21,YLC23 and YLC13 have good results,which are characterized by more fruits and excellent nut quality.The average yield of nuts per plant is 1.82 kg,0.50 kg,0.92 kg,0.32 kg and0.29 kg respectively,and the contents of nut fat and protein are 74.60%,68.4% and 71.0 respectively.According to comprehensive evaluation and analysis,Pawnee,YLJ42 and YLC23 are better fruit varieties,YLC21 and YLC13 are both fruit and timber varieties,and YLC29 and YLC12 are better ecological reserve varieties.
