摘要
1988年在吉安市青原区白云山林场营建的我国第一个杉木种源种子园(面积15hm2)于1990年开始投产后,每年所产的种子都用于江西及其它省区重点工程造林,产生了较大的经济和社会效益。由于本种子园在营建之初就考虑了影响种子园种子产量和质量的诸多因素,与现有其它杉木种子园相比,在种子产量和质量方面都有较大程度的提高:1990-1997年,平均年产种量为39.45kg/hm2,平均发芽率达52.05%,最高达78%,远高于我国杉木一级种子发芽率的标准(45%)。杉木种子如此高的发芽率尚未见诸报道。
The first Chinese fir provenance orchard was constructed in Baiyunshan forest farm of Ji'an city in 1988, and the area of the orchard was 15 hm2. From 1990 to 1997 the mean annual seed yield reached 39.45 kg/hm2 and the mean germination percentage was 52.1%(the highest was up to 78%)which is far higher than national germination percentage standard for the first-class Chinese fir seeds(45%).Such an high germination percentage for Chinese fir is reported for the first time.
