会泽县有不少高海拔地区,这样的地区往往春寒、旱重,核桃嫁接成活较低。为解决这一问题,近年来我县连续在海拔2100—2200公尺的地方试验核桃根颈嫁接法,并取得了成功,现简要介绍如下: 一、接穗处理适宜核桃嫁接愈合生长的温度,为恒定的26至30℃,湿度50％,接后15天左右可愈合生长。15至20℃时生长缓慢,低于
Huize county there are many high altitude areas, such areas are often cold spring, dry weight, walnut grafted lower survival. In order to solve this problem, in recent years, the county has continuously tested the walnut root-neck grafting method at an altitude of 2100-2200 meters and has achieved success. The brief introduction is as follows: First, the temperature at the grafting treatment suitable for the grafting and healing growth of walnut is Constant 26 to 30 ° C, humidity 50%, then pick up after about 15 days to grow. Slow growth at 15 to 20 ° C, below
