摘　　要：核桃高接换优是解决核桃园结果晚、品种良萎不齐,提高核桃园效益的有效技术手段。天水市秦州区核桃园大多建在高海拨区域,气候冷凉,采用传统的方块芽接技术要在6月底以后才能嫁接,时间晚,生长量小,枝条生长不充实,给越冬带来困难。为此在2015-2020年开展了核桃夏季嫩枝嫁接技术研究,把嫁接时间提前到了5月中下旬,大大地延长了嫁接枝的生长期,增大了新梢生长量。同时采用此项技术还解决了由于没有专业采穗圃造成接穗紧缺的问题。可以在生产中推广。Walnut high pick in optimal is an effective technique to solve the problem of late fruit,uneven cultivars and improve the efficiency of walnut orchard.The walnut orchard in Qinzhou District of Tianshui City is mostly built at a high altitude,and the climate in this area is cold.The traditional square bud grafting technique could only be grafted after the end of June.The time was late,the growth was small,and the growth of branches was not full,which brought difficulties to overwintering.Therefore,the research on the grafting technique of walnut tender branches in summer were carried out,and the grafting time was advanced to the middle and late May,which greatly prolonged the growth period of grafted branches and increased the growth of new shoots.At the same time,this technique also solved the problem of scion shortage caused by no professional scion orchard.
