为了科学地划定种子调拨范围,为一定地区选择最优良的品种,进一步促进杉木的速生丰产,我所于1977年春参加了全国杉木种源试验,现将苗期试验观察情况初报如下: 一、材料和方法 试验材料来自全国11个省（区）、21个产地母树林中一般正常结实的杉木种子（表1）。各产地种子均按全国试验方案统一编号。试验对照为本省句容县林场,编号为0（表2）。 In order to scientifically delineate the scope of seed transfers, select the best varieties in certain areas and further promote the fast-growing and high-yielding of Chinese fir, I participated in the national test of provenance of Chinese fir in the spring of 1977. The preliminary observations of seedling experiment are as follows: MATERIALS AND METHODS Materials from the 11 provinces (districts) in the country and 21 normal provenance Chinese fir seed in the origin field (Table 1). The origin of the seed according to the national test program unified number. The experimental control is Jurong County Forest Farm of the province, No. 0 (Table 2).
