我国东北区中北部(辽宁省沈阳以北和吉林、黑龙江)葡萄栽培历史虽然较久,但发展速度缓慢,栽植面积小而零星。主要原因是由于冬季酷寒和所栽培的品种抗寒力弱,从而冬季防寒需要大量的材料与劳动力所致。因此,除尽快的培育出抗寒、早熟、丰产、质优的新品种以外,提高现有葡萄品种的抗寒力具有重要意义。 作者于1956年以来,研究培育出了以贝达(Beta)品种做砧木的抗寒嫁接苗5,000余株,分别试栽于辽宁、吉林和黑龙江等省,现均已结果。现将这些嫁接苗在一般栽培条件下与同品种的自根苗对其抗寒力、生育、产量及抗病等特性的考察比较结果报导如下:
The northeastern region of northeastern China (Liaoning Province, north of Shenyang and Jilin, Heilongjiang) viticulture history, although a long time, but the development of slow, small and sparsely planted area. The main reason is that due to the winter cold and cultivated varieties of cold hardiness, so cold winter requires a lot of materials and labor due. Therefore, in addition to cultivating new varieties of cold hardiness, early maturity, high yield and high quality as soon as possible, it is of great significance to improve the cold hardiness of the existing grape varieties. Since 1956, the author has cultivated more than 5,000 strains of cold-tolerant grafted seedlings that are made of Beta variety, and planted them in Liaoning, Jilin and Heilongjiang provinces, respectively, all of which have been reported. Now these grafted seedlings in the general cultivation conditions and the same species of self-root seedlings on its cold hardiness, fertility, yield and disease resistance and other characteristics of the comparison reported as follows:
