为提高凤梨释迦嫁接成活率,以普通番荔枝为砧木,设置砧木粗度0.5~1.0、1.0~1.5、1.5~2.0、2.0~3.0 cm 4个处理,并分别采用不同嫁接口膜封处理,即常规封口法为对照,破膜导流法、嫁接部位切口法和涂抹剂涂抹法等不同嫁接口封口法,比较不...为提高凤梨释迦嫁接成活率,以普通番荔枝为砧木,设置砧木粗度0.5~1.0、1.0~1.5、1.5~2.0、2.0~3.0 cm 4个处理,并分别采用不同嫁接口膜封处理,即常规封口法为对照,破膜导流法、嫁接部位切口法和涂抹剂涂抹法等不同嫁接口封口法,比较不同处理的嫁接成活率。结果表明,砧木粗度0.5~3.0 cm时,枝接破膜导流处理的嫁接苗均表现为无明显伤流积液,且嫁接成活率均在90%以上;砧木粗度2.0~3.0 cm时,嫁接成活率最高,可达到95%。砧木粗度2.0~3.0 cm条件下,仍以破膜导流法处理的嫁接成活率最高,超过90%。说明破膜导流法能显著提高凤梨释迦嫁接成活率,可在生产上推广应用。展开更多
