摘　　要：以同批次播种的薄壳山核桃品种‘绍兴’实生苗为砧木,‘金华’、‘马罕’、‘波尼’当年生枝为接穗,于砧木苗生长的当年夏秋季节和次年春夏季节分别进行芽接和枝接试验,调查并研究其成苗率、苗高和穗条粗度.结果表明：当年夏秋芽接和次年春夏枝接最高成苗率分别为97.35％和84.97％,最低成苗率为82.11％;平均苗高最大164.94 cm,最小为80.33 cm;平均穗条粗度9.46～ 16.43 mm.经分析,在同批次砧木中,当年夏秋芽接的成苗率显著高于次年春夏枝接;品种间成苗率差异不显著.嫁接方法和品种均对苗高和穗条粗度有显著影响,夏秋芽接苗高和穗条粗度均极显著高于春夏枝接;薄壳山核桃品种‘波尼’和‘马罕’的苗高、穗条粗度均显著高于‘金华’.研究结果表明,在一年的时间内分别进行春夏枝接和夏秋芽接育苗是可行的.The same batch of pecan cultivar ‘Shaoxing＇seedlings were used as rootstocks,varieties of ‘Jinhua＇,‘Mahan＇,‘Pawnee＇new shoot were used as scions,when the rootstocks were 6（ the summer of the first year） and 15（ the spring of the second year） month old,budding and grafting experiments were conducted respectively. The seedling rate,seedling height and stem diameter were investigated and studied. According to the survey,among all 6 tests,the highest seedling rate of budding and grafting were 97. 35% and 84. 87% respectively,the lowest seedling rate was 82. 11%. The maximum of average height was up to 164. 94cm,the minimum was 80. 33mm. The average stem diameter was 9. 46-16. 43mm. In the same batch of rootstocks,the seedling rate of budding was significantly higher than that of grafting. The seedling rate was not significantly different between varieties. Grafting methods and cultivars exerted a significant impact on seedling height and stem diameter,budding seedling height and stem diameter were significantly higher than those of grafting. Seedling height and stem diameter of ‘Pawnee＇and ‘Mahan＇were significantly higher than that of ‘Jinhua＇.
