芽接是繁殖毛白杨的一种好方法。但嫁接季节,多在雨季进行,时间短,出圃晚。为了延长芽接时间,我们进行了春季芽接试验,效果良好。1981年4月初在县政府大院的大官杨上试接,获得成功,随于1982年春,在冀午渠2年生大官杨苗圃地,进行了较多数量的芽接。接后10天检查,一处成活率为90％,一处为85％。当年11月份调查,平均苗高3.5米,最高达4.25米,最低2.83米;平均基径3厘米。当年即可出圃。
Budding is a good way to breed white poplar. However, the grafting season, mostly in the rainy season, a short time, a nursery night. In order to extend the budding time, we conducted a spring budding test, the effect is good. At the beginning of April 1981, he was tested and qualified at the top of the county government compound, Yang Yangpu, who was a 2-year-old resident of Jiuliuqu in spring of 1982 and conducted a large number of budding. After 10 days to check, a survival rate of 90%, a place for 85%. In November of that year survey, the average seedling height of 3.5 meters, up to 4.25 meters, the lowest 2.83 meters; average base diameter of 3 cm. That year can be nursery.
