1977—1979年我省宜宾、涪陵、温江、乐山、雅安、成都等地市开展了群众水杉扦插育苗。为发展水杉生产,我们选择气候类型、立地条件近似的地方,采取机械抽样设置标准地调查,扦插苗面积1米~2,移植苗10米~2,根据具体情况设5—10个标准地测定。现将所得资料整理如下。 From 1977 to 1979, masses of Metasequoia cuttings were raised in Yibin, Fuling, Wenjiang, Leshan, Ya’an and Chengdu cities of our province. In order to develop Metasequoia, we choose the climate type, the site conditions similar to the place, to take the standard sampling of mechanical sampling survey, cutting seedlings area of ​​1 m ~ 2, transplanting seedlings 10 m ~ 2, according to the specific situation set 5-10 standard . The information is now organized as follows.
