连续7年对12种桃砧木类型进行比较试验(嫁接品种为大久保和连黄),结果表明,毛桃与两品种亲和力最强,砧/穗接合部位相近一致,愈合良好,生长旺盛,但与其他砧木比,早期产量低;山桃、陕甘山桃,产量高,早期丰产性好,品质优,但大脚现象明显,易染根癌病;甘肃桃1号对南方根结线虫免疫,抗旱能力强,适合丘陵薄地、沙质土地栽植;光核桃类型多,亲和力种内表现不一,其中以光核桃王、光核桃3号表现较好,但表皮粗糙易受天牛为害;毛樱桃矮化效果明显,树冠只有毛桃的2/3～1/2,可进行密植栽培,但株间亲和性分离广泛,须经纯化或采用优株营养系,才能应用于生产。大久保与不同砧木的亲和性不如连黄,连黄在不同砧木间的砧/穗比差异不显著。砧/穗比可以作为衡量亲和力的指标之一。
The results showed that the peach had the highest affinity with the two varieties, the anvil / spike joint was similar, the healing was good, the growth was vigorous, but compared with other types of peach rootstocks for seven consecutive years (the grafted varieties were Okubo and Lianhuang) Rootstock ratio, early yield is low; peach, Shanxi Gansu peach, high yield, good early yield, good quality, but obvious bigfoot phenomenon, easy to dye root cancer; Gansu peach 1 root knot nematode immunity, drought resistance , Suitable for hilly thin, sandy land planting; light walnut type, affinity within the species showed different, of which the light walnut king, light Walnut 3 performed better, but the epidermis is vulnerable to the damage caused by Tian cattle; dwarf cherry hair effect Obviously, the crown only peach 2/3 ~ 1/2, dense planting can be carried out, but strains widely isolated, subject to purification or use of superior strains of nutrition, can be applied to the production. Okubo with different rootstock affinity as yellow, even yellow in different rootstock anvil / spike ratio was not significant. Anvil / spike ratio can be used as an indicator of affinity.
