红杉(Sequoia semperiems(lamb)Endl)原产美国加利福尼亚西海岸,它生长迅速,材质优良。我场于1977年、1978年从杭州引入红杉扦插苗,栽植在成都和洪雅林区,生长欠佳、偏冠。为了诱导红杉适应本地生长,扩大生理生态适应幅度和加速红杉苗木生产,1979年以来,我们将红杉嫁接在杉科其它种树苗上,观察其成活和生长情况,并对嫁接技术以 Sequoia semperiems (lamb) Endl) is native to the west coast of California, USA. It grows rapidly and has good materials. My field in 1977, 1978 Sequoia cuttings introduced from Hangzhou, planted in Chengdu and Hong Ya Lin, poor growth, partial crown. In order to induce Sequoia to adapt to the local growth, expand the eco-physiological adaptability and accelerate the production of Sequoia saplings, we sequestered the Sequoia trees on the other species of Sequoia so as to observe their survival and growth.
