在建立杉木嫁接种子园过程中,存在着接穗来源不足和嫁接植株容易偏冠等问题。为了提高接穗利用率和克服偏冠现象,今春,我们采用皮接法,并作了两种不同处理:一种是用一年生侧枝主梢上的皮;另一种是用一年生主干上的皮,每一处理接10株。 皮接方法是从去掉叶针的接穗上,用芽接刀切成长1.0—1.5厘米、宽0.5—1.0厘米、不带木质部的皮作接穗。砧木离地面约20厘米处截断,并将距截面1厘来左右的针叶摘除,切
In the process of establishing the seed grafting cunninghamia lanceolata, there are some problems such as the insufficient source of scion and the tendency of the grafted plant to crown easily. In order to improve the efficiency of scion and overcome the phenomenon of partial crowns, this spring, we use the skin method, and made two different treatment: one is the main branch of the annual shoots on the skin; the other is the annual trunk of the skin, Each treatment received 10 strains. Skin access method is removed from the scion of leaf needles, with budding knife cut 1.0-1.5 cm, 0.5-1.0 cm wide, without xylem skin as a scion. Rootstock truncated about 20 cm from the ground, and about 1% from the cross-section of needle removal, cutting
