<正>以毛桃为砧木，紫叶桃和寿星桃为接穗，嫁接后分别于５、１０、１５ｄ剪砧，研究了观赏桃芽接剪砧的最适时期。结果表明：紫叶桃嫁接后１５ｄ剪砧，寿星桃嫁接后５天剪砧，不仅嫁接成活率（９２．０％～９８．６％）和成苗率（９１．４％～９２．０％）高，新梢生长旺盛，根系生长良好，地上部分和地下部分的异速生长也符合观赏的要求，而且净收益增加。

A study was made on bud-grafting with Prunus persica(L.)as stocks and P.persica var.atropurpurea schneid schneid and var.densa Makino as scions in late July,The stock parts above the scions were cut-off 5,10 and 15 days after grafting respectively. The results obtained indicate that P.persica var.atropurpurea Schneid with removal of upper stocks grafted after 15 days and P.persica var.densa with that after 5 days were most desirable.97.0%-98.6% survival and 91.4%-92.0% became young plants with vigorous shoots respectively.
