摘要
试验分析了砧木选择、嫁接时间、嫁接方法等因子对干旱、半干旱地区异砧红松嫁接成活率和生长的影响。结果表明:樟子松、油松、赤松均可作为砧木嫁接红松。采用单芽接穗好于多芽接穗;适时早接有利于接穗木质化程度的提高;正交试验结果显示最佳处理组合为A1B1C1,即砧木为樟子松、4月中旬嫁接、芽端楔接法的组合,成活率达到90%以上。
Effect of rootstock selection,grafting time,grafting methods on survival rate growth of Pinus koraiensis were analyzed.Result shows that： Pinus sylvestris var.mongolica,Pinus tabulaeformis,Pinus densiflora all can be used as rootstock;single-bud appear optimal than multiple-bud;appropriate early grafting received favorable on scion lignification improvement;result of orthogonal experiment shows that ：the optimal treatment combination is A1B1C1,namely the the combination of stock being Pinus sylvestris var.mongolica＋bud-side wedge grafting being in mid-April can obtain survival rate being over 90%.
