对苹果矮化砧崂山柰子特性的研究表明,砧木的根皮率高;压条繁殖较易生根;用作中间砧嫁接的1年生果苗及成龄树的根系发达,且分布广而深;其中间砧嫁接的苹果幼树,矿质元素的吸收水平较高。选出了嫁接亲和良好、树体半矮化,早果、丰产性好的崂山柰子优系N29、N32。砧穗组合的研究表明,崂山柰子自根砧嫁接的红星、倭锦等品种大树,表现矮化、早果、稳产;作中间砧,与印度、乔纳金和红富士组合表现较好。
The study on the characteristics of Laoshan prickly heat of apple dwarfing anvil shows that the root bark rate of rootstock is high, the rooting rate of rootstock is higher, the rooting is easier and the root system of 1-year-old fruit seedling and adult tree is good and widely distributed. Interstock grafted apple saplings, the absorption of mineral elements higher. Selected a good affinity grafted, semi-dwarf tree, early fruit, good yield Laoshan Bangzi excellent lines N29, N32. The research on the combination of rootstock and scion showed that Laosangzi self-rootstock grafted Rhodiola sachalinensis and other species, dwarfing, early fruit, stable yield; as the middle anvil, with the combination of India, Jonathan and Red Fuji performed well .
