果树改接(或高接)是一种快速有效的品种更新技术措施,但由于砧穗间粗度差异较大,往往在改接后出现伤口愈合不良的现象,易受病菌侵染而使树体衰退。本试验结果证明,套塑料袋改接能明显提高成活率,并非常显著地促进了截伤面的愈合。改接试验于1983年4月下旬开始,所用接穗是冬天沙藏的芽体饱满、组织充实的长富2接条,砧木为本场果园的三年生海棠,
Fruit tree to change (or high) is a quick and effective variety of technical measures to update, but because of the large differences between the thickness of the rootstock, often after the switch to the phenomenon of poor wound healing, susceptible to infection and make the tree Body declines. The test results show that the set of plastic bags can significantly improve the survival rate, and significantly promote the wound healing. The switch to the test began in late April 1983, the scion is rich in buds of winter sand possession, enrichment of long rich 2 junction, the rootstock for the field orchard three-year-old Begonia,
