北京林业大学与河北省涿鹿县科委协作,在大堡乡搞沙棘扦插育苗试验研究,获得突破性的成果。通过部级鉴定,专家认为这项技术为国内首创,其扦插发根率己达到国际水平。解决了沙棘苗木人工控制雌雄株,短期内大量培育相同遗传性的自根苗等技术问题。四年来,先后建起了国内仅有的电子间歇自控全光喷雾育苗装置,建起5亩嫩枝、硬枝扦插试植示范围。1987年扦插成苗的两万株,平均苗高40厘米,地径0.5厘米,在
Beijing Forestry University and Hebei Zhuolu County Science and Technology Commission collaboration in Fort Township engaged in seabuckthorn cutting seedling pilot study, access to breakthrough results. By ministerial appraisal, experts believe that this technology is the first in China, the rooting rate of its cutting has reached the international level. Solved the artificial control of seabuckthorn seedlings male and female plants, in the short term large-scale cultivation of the same genetic self-rooted seedlings and other technical issues. In the past four years, we have built the only electronic batch-controlled all-optical spray seedling raising device in China and built 5 mu of tender shoots and hard branch cuttings. Tens of thousands of cutting seedlings in 1987, the average height of 40 cm, 0.5 cm diameter, at
