摘 要:将YLC21,YLC23,YLJ35,YLJ42,马罕5个美国山核桃品系通过苗木引进方式引种至山西晋南地区,以美国山核桃实生苗为对照,研究其适应性。结果表明,定植当年YLC21树高年平均生长量最高,达60.7 cm;YLJ42地径年平均生长量最大(8.5 mm),显著高于其它参试品种;YLJ35(60.8 cm)新枝年平均生长量最高。定植第3年,YLC21(139.9 cm)树高年平均生长量最高;YLC21(14.3 mm)地径年平均生长量最高,YLJ42(13.4 mm)次之,与马罕、对照之间差异显著。In order to study the adaptability of Carya illinoinensis,5 strains including YLC21,YLC23,YLJ35,YLJ42 and Mahan were introduced to southern Shanxi with the seedling plant of Carya illinoinensis as control.Results showed that the average height growth of YLC21 was the highest in the year of planting,which reached 60.7 cm.The average ground diameter growth of YLJ42 was the largest(8.5 mm),which was significantly higher than other strains.The average growth of new branches of YLJ35 was the highest(60.8 cm).In the third year of planting,the average height growth of YLC21(139.9 cm)was the highest.The average ground diameter growth of YLC21(14.3 mm)was the highest and followed by YLJ42(13.4 mm),which was significantly different from that of Mahan and control.
