【摘要】 以东部白松为接穗、红松为砧木进行异砧芽接试验,结果表明:嫁接后1个月接芽开始伸长,秋季嫁接成活率平均为92.1%,接合部以上高生长量平均为12.3 cm。与髓心形成层贴接相比较,芽接繁殖材料采集量可提高3倍以上,砧木创伤长度缩小60%以上,绑扎材料用量节省30%以上,绑扎效率提高50%以上,平均嫁接速度提高20%,操作过程更为方便。更多还原

【Abstract】 The heteroplastic bud grafting experiment was carried by taking Pinus strobes and Pinus koraiensis as cion and stock. The result showed that the budder began to elongate after grafting for 1 month. The average survival rate of grafting was 92. 1 % in autumn. The average height increment above adjoiner was 12. 3 cm. Compared with pith cambium grafting,budding breed material collection can increase by more than 3 times,the trauma length of stock decrease by more than60 %,the strap material utilization amount saved more than 30 %,the strap efficiency increased by more than 50 %,the average grafting speed increased by more than 20 %,the operation process was more convenient.更多还原
