(一)选好接穗:一是从优良母树上采接穗,优良母树必须枝条粗壮,成枝率低,主枝角度开张,发芽晚,落叶迟,叶片大而厚,叶浓绿等。二是选择老枝作接穗。因为银杏幼树结果期与接穗年龄成反比,即接穗年龄越大,结果期越早,而嫁接苗提早结果都来自接穗,所以一定需三年以上的结果枝采接穗。(二)嫁接促花:嫁接苗的输导组 (A) Selection of scion: First, from the good mother tree mining scion, good mother tree branches must be sturdy, low rate of branches, the main branches open angle, late late leaves, large and thick leaves, dark green leaves. Second, choose the old branch for the scion. Because the results of ginkgo young trees and scion age is inversely proportional to the age, that is, the older the scion, the earlier the results, while the early grafted seedlings are scions from the result, it must take more than three years results scion branches and plums.
