我分场于一九七六年采用树冠芽接的办法接上抗寒品系的树冠,建立一个高产品系种子园,以解决生产上急需的抗烂砧木的种子。选择了三队一块半阳坡一九七三年定植的RRIM600幼树林地,经七三—七四年冬寒害后于一九七四年返抽出的幼树上进行树冠芽接改造,建成GTl×PR107的双品系种子园,共接1452株,成活1380株,成活率为95.53％。改后一年零九个月幼树冠恢复迅速,并巳开花结
In 2006, I set up a high-yielding seed orchard in order to solve the problem of seeds that are badly-needed anti-rotting rootstock in production. Three teams of RRIM600 young woodland planted in 1973 in the semi-sunny slope were selected for tree crown splicing reformation after sapling in winter in 1973-724 and back in 1974, and GTl × PR107 double-line seed orchard, a total of 1452 strains, 1380 survive, the survival rate was 95.53%. One year and nine months after the change, the young canopy has recovered rapidly and has begun to blossom
