五针松为常绿小乔木,生长缓慢,枝叶茂密,树势端庄优雅,是珍贵的观赏盆景树朴。它原产日本,我国为引种栽培。目前五针松的繁殖,普遍是采用2年生黑松苗作砧木、五针松小枝作接穗,进行基部腹接。惟此法需要的接穗量大,易伤母树;接苗当年生长缓慢,难于管理,成活率低。因此,宜兴县林场官山坞工区从1984年春开始进行了五针松芽接法(芽腹接、顶芽劈接)的探索,现已获得良好的结果。三年芽接(芽腹接、劈接)6,066株,成活了5,477株,成活率高达90.3％,当年平均生长量12厘米,最高生长量达26厘米。而用小枝腹接12,320株,成活4,965株,平均成活率仅为40.3％,当年平均
Five needles for the evergreen small trees, slow growth, dense foliage, dignified dignified elegance, is precious ornamental bonsai tree Park. It is native to Japan, China is the introduction of cultivation. At present, Pinus sylvestris var. Mongolica breeding is generally adopted 2-year-old black pine seedlings as rootstocks, Pinus pinaster as scions, the base of the abdomen. However, this method requires a large amount of scion, easy to hurt the mother tree; then grow slowly, difficult to manage, low survival rate. Therefore, the Yinshan County Forest Farm Guanshan dock area from the spring of 1984 started five needle pine bud method (bud abdomen, top bud cleavage) exploration, has now achieved good results. In 2006, 6,066 plants were budded and sprouted, 5,477 plants survived. The survival rate was as high as 90.3%. The average annual growth was 12 cm and the maximum growth was 26 cm. However, 12,320 plants were abdominally and 4,965 were survived. The average survival rate was only 40.3%
