摘 要:为改进栽培措施,提高核桃方块芽接成活率,用香玲核桃枝条不同芽位的芽片作试材,研究了不同部位接芽对核桃方块形芽接成活及生长的影响。结果表明:5月29日、6月5日和6月12日嫁接时,下部接芽的成活率分别为91.4%、91.8%和90.5%,中部接芽的成活率分别为97.9%、97.5%和95.5%,上部接芽的成活率分别为93.0%、94.7%和92.2%。嫁接成活率均为中部芽最高,可显著高于其他部位接芽,上部次之,下部最低。嫁接后第10、15、20 d,中部芽片的嫁接苗生长最快,上部次之,下部最慢。In order to improve the cultivation and enhance the square budding survival rate,effects of different buds on square budding survival rate and grafted seedlings growth of Juglans regia were studied using different axillary buds of Xiangling walnut.The survival rate and grafted seedlings growth were observed.The results showed that on the grafted date of May 29th,Jun 5th and Jun 12th,the survival rates of the lower bud on the scion were 91.4%,91.8%,and 90.5% respectively,and that the middle bud and the upper bud on the scion were 97.9%,97.5%,95.5% and 93.0%,94.7%,92.2% respectively.The budding survival rates using the middle bud on different grafted dates were the highest,and significant higher than other treatments,next were the upper bud,the budding survival rates using the lower bud were the lowest.The growth rates using the middle bud on different grafted dates were the fastest after 10,15,and 20 days,next were the upper bud,the grafted seedlings growth rates using the lower bud were the slowest.
