寒地苹果不同砧穗组合的栽培表现

Cultivation Performance of Different Apple Rootstock Combinations in Cold Region

河北省抗寒苹果产业技术创新中心于2018年4月在平泉市小寺沟镇示范园区定植基砧为山定子、矮化砧中间砧为GM256的‘寒富’‘岳艳’‘岳华’‘岳冠’3年生带分枝大苗,对照采用山定子为基砧、SH40为矮化砧中间砧的上述品种3年生带分枝大苗,观察不同砧穗组合的栽培表现。结果表明,以GM256为中间砧的各组合抗寒能力强,耐旱,耐贫瘠,适应性强,极易丰产,且管理简单,适宜在冀北寒冷地区及相似生态类型区推广应用。

In April 2018,the Hebei Province Cold-resistant Apple Industry Technology Innovation Center planted 3-year-old branched seedlings of‘Hanfu’‘Yueyan’‘Yuehua’and‘Yueguan’in the demonstration park of Xiaosigou Town,Pingquan City,with a base stock of Shandou and a middle stock of GM256 for dwarfing rootstocks.The cultivation performance of different rootstock ear combinations was observed by comparing the 3-year-old branched seedlings of the same variety with Shandou as the base stock and SH40 as the middle stock of dwarfing rootstocks.The results showed that the combinations using GM256 as the intermediate rootstock had strong cold resistance,drought resistance,poor tolerance,strong adaptability,high yield,and simple management,making them suitable for promotion and application in cold regions of northern Hebei and similar ecological types.
