因为在苹果方面存在着砧木利用方法的混乱,所以,从容易理解的砧木利用法出发,整理出苹果栽培型(附图)。 (A)是自根方式。要使苹果品种保持繁殖性,就应以不使用砧木作为栽培苹果的新的栽培型。实际上英国正在开展着这项研究。即:用自根系进行繁殖。 (B)是普通方式。 (C)由于繁殖矮化砧木有困难,所以,在圆叶砧木等(可能指海棠等—译者注)一些容易繁殖的砧木和品种接穗之间,插进一根长约20—30厘米的矮化砧木,用以作为谋求矮化性。这个中间砧木可以完全放在地面上,它的实际意义就是中间砧木方式。
Because of the chaos in apples used for rootstocks, apple cultivars (photos) were sorted out from easily understood rootstocks. (A) is self-rooted. For apple varieties to remain reproductive, rootstocks should not be used as a new cultivated form of cultivated apples. In fact, the UK is conducting this research. Namely: use self-root system for breeding. (B) is the normal way. (C) Since it is difficult to breed dwarf rootstocks, between rootstocks, such as leafstocks, which are easily reproduced, and the scion of the cultivar, a root of about 20-30 cm Dwarf rootstocks, used as a dwarfism. The middle rootstock can be completely placed on the ground, its practical significance is the middle rootstock way.
