应用矮化砧木实生苹果矮化栽培,是当前世界苹果栽培的趋势。但矮砧的选育是一项工作量极大而费时较长的工作,所以矮化砧木的早期鉴定在砧木选育过程中具有重要意义。我国苹果矮砧资源极为丰富,作为矮砧材料的树种远远超出国外通常采用的道生苹果(Malus pumila var praecox Pall)和乐园苹果(M.pumila var paradisiaca Schneider),甚至不是苹果属的植物,如水枸子(Contoneaster multiflorus Bunge),这是我国矮砧选育的一个特点。 Application dwarf rootstock apple dwarf cultivation, is the current world trend of apple cultivation. However, the breeding of dwarf stocking is a heavy and time-consuming work, so the early identification of dwarfing stock is of great significance in stock selection. The resources of apple dwarf rootstock in our country are very rich. The species of dwarf anvil material far exceeds that of Malus pumila var praecox Pall and M. pumila var paradisiaca Schneider which are commonly used in foreign countries, and not even apple genus plants such as water Cotoneaster (Contoneaster multiflorus Bunge), which is a feature of breeding of dwarf anvil in our country.
