Stndy on the Second Newly Branch Cuttage of Eucommia Ulmoides Olv
In this article,a kind of measure which can make the Eucommia Ulmoides tree put forth twice a gear has been provided and analyzed. The experiments,about the maternal branch's angle of the artificial second newly branch and the ralationship between cutting position and the rooting rate,have been done. The arganical matter content was determined. And the rooting condition are compared. The study showed that smaller angle maternal branches sprout more and better second newly branches,the rooting rates and the organical matter conditions are remarkably different,and the second newly branches may be used in cutting propagationg production.
