1974年以前,我们对国外松育苗曾采用营养篓、营养杯、营养砖、点播、密播移芽等多种方法进行育苗,以密播后移芽的育苗方法效果较好。1974年,我们种植湿地松、加勒比松等共5000亩,大都是用“移芽”的方法育苗,苗根发达,幼苗生长良好,三个月左右,苗高15～20厘米,造林成活率达百分之九十以上,且能节约种子,发芽期管理方便。 Before 1974, we have used nutrient baskets, nutrition cups, nutrition bricks, on-demand, in-depth buds and other methods to nursery pine seedlings in foreign countries. In 1974, we planted a total of 5,000 mu of Pinus elliottii and Cariboe pine. Most of them used the method of “transplanting buds” to nurture seedlings and developed seedlings. About three months, the seedling height was 15-20 cm and the survival rate for afforestation was Ninety percent or more, and can save seeds, germination management easy.
