嫩江地区位于黑龙江省西部,全区(包括齐齐哈尔市郊区)风沙土占总面积的15％左右,气候特点是风大、干旱、日照长,夏季积温高,对葡萄生长有利。但由于冬季寒冷,现有栽培品种不耐寒,对生产的发展有很大影响。我们在抗寒栽培技术研究的第一个阶段,是利用抗寒砧木培育嫁接苗,通过换根简化防寒。目前嫁接育苗在生产中还存在一些问题。其中就劈接而言,方法比较复杂。用抗寒的山葡萄做砧木,嫁接成活率低。因此,我们工作的重点是研究改进嫁接方法,探索不同砧木的利用,总结愈合处理、移植等技术措施,简化方法,提高成活率,迅速培育出大量的嫁接葡萄苗,提供生产栽培,两年来取得了初步结果。
The Nenjiang area is located in the west of Heilongjiang Province. The sandy area covers an area of about 15% of the total area of the whole area (including the suburbs of Qiqihar). The climatic characteristics are windy, droughty, long sunshine and high accumulated temperature in summer, which is beneficial to grape growth. However, due to the cold winter, the existing cultivars are not hardy and have a great impact on the development of production. The first stage of our research on cold-resistant cultivation techniques is to cultivate the grafted seedlings with cold-hard stock and simplify the cold by changing the root. At present, grafting seedling in the production there are still some problems. Among them, in terms of split, the method is more complicated. With cold mountain grape as rootstock, grafting survival rate is low. Therefore, the focus of our work is to study and improve the grafting methods to explore the use of different rootstocks, summarize the healing treatment, transplantation and other technical measures to simplify methods and improve the survival rate, quickly cultivate a large number of grafted grape seedlings, to provide production and cultivation, made two years The initial result.
