金松(Sciadopitys verticilla-ta)是日本特产的杉科植物,其叶形奇特、树姿优美,与南洋杉、雪松一起被誉为世界三大园林树种。目前我国引种金松的单位不多,仅庐山有大树生长,因此金松种子很珍贵。为了提高金松种子的发芽率和小苗的成活率,我们经过栽培实践总结出了一些经验,现介绍如下。四月中旬用1%的高锰酸钾水溶液消毒金松种子2小时,然后捞出洗净,冷水浸种24小时,再与消过毒的纯沙混合,置于温室内催芽。
Jinsong (Sciadopitys verticilla-ta) is a Japanese specialty of Cunninghamia species, the peculiar leaf shape, beautiful tree pose, and Araucaria, Cedar known as the world’s three major garden tree species. At present, there are not many units in China that are introduced to the golden pine, and only the giant tree grows in the Lushan Mountain. Therefore, the golden pine seed is very precious. In order to improve the seed germination rate and the survival rate of gold seedlings, we have summed up a number of practices through cultivation practice, are presented below. In mid-April with 1% potassium permanganate disinfection of pine seeds for 2 hours, then remove and wash, soaked in cold water for 24 hours, and then sterilized pure sand mixed, placed in the greenhouse germination.
