清香核桃引种试验初报

Preliminary report on introduction experiment of Juglans regia ‘Qingxiang'

为筛选适合川南低山丘陵区种植的核桃优良品种,从河北省定州市引进性状表现优良的清香核桃嫁接苗在四川省峨眉山市栽培,观测其引种表现,对生长物候期、生长结果习性、抗性等进行研究。结果表明,清香核桃各项经济指标与原产地基本相同,该品种适宜在川南低山丘陵区域发展。作为抗旱和耐土壤贫瘠的树种,建议在川中丘陵区做中试试验。

In order to provide some fine Juglans regia cultivars for planting at hilly areas of southern Sichuan, some grafted seedlings in J. regia ＇Qingxiang＇ with some super characteristics, which were introduced from Dingzhou City of Hebei Province, were planted in Emeishan City of Sichuan Province, its introduction performance was observed, and growth phenology, fruiting habit and resistance in J. regia ＇Qingxiang＇ were researched. The result showed that the cultivar had the same economic indexes as that in the origin, and it was suitable to cultivate at low hilly areas of southern Sichuan. As a kind of tree species with the drought and poor soil resistance, middle test should be done at hilly areas of central Sichuan.
