影响杨梅大树高接成活率因子探析

以随机区组设计，综合分析了不同砧木状态、不同年龄接穗、穗条不同处理、不同嫁接人员、气候条件等因素对杨梅大树高接成活率和接穗生长情况的影响。结果表明：嫁接过程中砧木状态、穗条的生理年龄及处理方法、环境条件对杨梅高接成活率影响较大，杨梅品种和嫁接人员不是影响嫁接成活的主要因子；部分因子对穗条新梢生长及分枝数均有一定影响。在杨梅大树高接时，应选用生理年龄轻的穗条，选择适宜的气候条件、砧木类型以及技术娴熟的嫁接工，随采随接，有利于杨梅大树高接的成活；同时选择生长充实、芽眼饱满的穗条及根系完好、生长健壮的砧木进行嫁接可加速穗条生长和增加分枝数，有助于提早结果。

Analysis on Factors Effecting Survival Rate in Adult Myrica rubra High- grafting

The factors effecting survival rate in adult Myrica rubra high-grafting and growth of scions were analysed comprehensively by random block design with different stock kinds, different scion ages and treatments, different grafting workers and environments etc. The results showed that conditions of stocks, scion ages and treatments, environments in grafting notably effected the survival rate, but cultivars and grafting workers were not the leading factors, and some factors effected the growth and ramification of scions. In adult Myrica rubra high-grafting, young sciono age, suitable environment and stocks, grafting workers were beneficial to the survival rate of grafting. Well-fed scions of full-grown buds and well-grown stocks of complete rootage promoted the growth of scions, increased ramifications, and benefited early bearing.
