苹果树高接换头已成为生产中快速更新品种的有效技术措施.但在高接过程中,由于砧穗两者之间粗度差异较大,往往在高接后出现伤口愈合不良的现象,加之易受各种病菌的侵染而使树体树势衰退,严重制约了高接树产量的迅速恢复.我们于1994年、1995年进行了苹果高接换头后应用套塑料袋的试验,结果表明,改接后套塑料袋能显著提高成活率和促进高接伤口面的愈合.
Apple tree high takeover has become an effective technical measure for the rapid updating of varieties in production.However, in the high take-up process, due to the large difference in thickness between the two rootstocks, the phenomenon of poor wound healing often occurs after the high takeover, Coupled with susceptible to a variety of germs infection and the decline of the tree shores, severely constrained the rapid recovery of the yield of high accession we conducted in 1994 and 1995, after the application of high plastic wrap apple sets of plastic bag test, The results showed that the plastic bags after the connection can significantly improve the survival rate and promote wound surface healing.
