针对陕北葡萄生产中存在的历史性冻害问题，利用抗寒砧木山葡萄、山玫瑰和贝达，通过嫁接巨峰、龙眼及京早晶品种，再采用覆土１０ｃｍ、２０ｃｍ、５０ｃｍ不同厚度的２６个处理，以研究品种、砧木与覆土间抗寒性。试验表明，影响陕北葡萄生产的主要问题是根系冻害。利用山玫瑰作砧木，冬季只需覆土２０ｃｍ厚，就可以使葡萄栽培品种在陕北安全越冬。
Aiming at the problem of historic frostbite in the production of grapes in northern Shaanxi, 26 grafting treatments of 10cm, 20cm and 50cm in thickness were applied by grafting the Kyoho, Longan and Jingzao varieties, , To study the variety, rootstock and overburden cold resistance. Experiments show that the main problem affecting grape production in northern Shaanxi is root frost damage. The use of mountain rose rootstocks, winter, only 20cm thick soil cover, you can make the grape varieties in northern Shaanxi safe winter.
