绪言一般认为苹果树是耐涝性强的果树,但实际上因根砧种类不同是会有差异的。为此,笔者等对几种苹果砧木进行过渍水处理试验,各种砧木之间的耐涝性是有很大差异的,即目前实际栽培应用的矮化砧的耐涝性比较弱,固有种圆叶海棠的耐涝性非常强。但这只是以砧木作比较时的结果,而必须考虑到在这些砧木上嫁接栽培品种时,由于地上部和地下部的相互作用,可能对耐涝性产生影响。为此, Introduction Generally believed that the apple tree is a fruit tree with strong waterlogging resistance, but in fact there will be differences due to the different types of root anvil. To this end, the author of several apple rootstocks had waterlogging test, a variety of rootstocks between the waterlogging is very different, that is currently practiced in the application of dwarfing anvil waterlogging weaker, intrinsic Begonia species of waterlogging is very strong. However, this is only the result of comparison of rootstocks, and account must be taken of the possible impact on waterlogging due to the interaction of shoots and subsurface areas when grafting cultivars on these rootstocks. to this end,
