高山铁核桃和绿皮核桃的休眠期比低海拔泡核桃休眠期长,如何使用泡核桃接穗改造高山铁核桃和绿皮核桃,是长期以来的技术难关之一。近年为适应山区发展核桃生产的需要,我们深入核桃产区,不断摸索和总结,取得了洞穴储藏泡核桃接穗的成功经验。一九八○年洞穴储藏泡核桃技条六穴共1,800条,储藏十五天,春尾取出技接,同年九月检查,成活1,600株,当年接穗株高30厘米。
Alpine walnut and green peach dormancy dormant longer than walnut low elevation, how to use walnut scion to transform alpine iron walnut and green peel, is one of the long-term technical difficulties. In recent years to meet the needs of the development of walnut mountainous areas, we go deep walnut-producing areas, and continue to explore and summarize, and achieved the successful experience of caves storage foam walnut. In 1980, a total of 1,800 pieces of almonds were stored in the cave at a rate of 1800. After 15 days of storage, they were removed from the spring tails and examined in September to obtain 1,600 plants. The scion plant height was 30 cm.
