通过在民勤干旱沙区进行酿造葡萄芽接、枝接和根接3种嫁接苗木培育方式及嫁接方法对比试验,结果表明:酿酒葡萄苗木快速繁育和品种改良的最好方法是枝接中的劈接法;酿酒葡萄在6月上旬到中旬进行枝接成活率高,是新品种苗木快繁和老树改良换种更新的最佳时期。本文旨在通过试验研究归纳总结出一套酿酒葡萄苗木快速繁育和老树改良换种更新的培育方式及嫁接技术,为同类地区酿酒葡萄产业发展提供技术参考。
The results showed that the best method for rapid breeding and variety improvement of grape seedlings is the cleavage of the grafted seedlings France; wine grapes in early June to mid-branch survival rate is high, is the new varieties of seedlings quickly propagation and improvement of old trees change the best time for renewal. The purpose of this paper is to summarize a set of cultivation methods and grafting techniques for the rapid breeding of grape seedlings and new varieties of old trees through experiment and research, and provide technical reference for the development of wine grape industry in the same area.
