核桃苗木嫁接技术对比试验

Comparative Experiment on Grafting Techniques of Walnut Seedlings

培育健壮的优良品种苗木,是发展核桃生产的基础条件之一,嫁接繁殖是比较有效的技术手段,能够早结果、早丰产。本文通过采用方块芽接和单芽切接两种不同的嫁接方法,发现单芽切接成活率最高为56%,而方块芽接成活率最高达90%以上。因此,最适宜该县核桃嫁接的方法是方块芽接。在此基础上,文章研究了核桃方块芽接技术要点,例如适宜核桃嫁接的砧木处理、嫁接时期、嫁接部位及嫁接后解绑的时间等,为核桃育苗提供参考与依据。

The cultivation of strong and fine varieties of nursery stock is one of the basic conditions for walnut production. Grafting propagation is an effective technique for early results and early high yield. By using two different grafting methods named square bud grafting and single-bud grafting, the result showed that the best survival rate of single-bud grafting was 56%, and survival rate of square bud grafting up to 9 0 % . Therefore, the most suitable grafting method of walnut is the square bud grafting. Then this paper studies the key technique of walnut square bud grafting, for example suitable for grafting of walnut rootstock treatment, grafting time, grafting position and after grafting unbundling time, in order to provide a reference for walnut seedling.
