为了缩短红松种子发芽期,我们根据奥列拉仁斯基所著的造林学上册中介绍红松种子处理的原理,采用了低温处理和变温催芽的方法。播种22天后,种子发芽出土,得到良好效果。所用种子,由黑龙江省调来,在马尔康县引种。该地海拔3100公尺,年平均温度11.5℃,雨量739mm。催芽方法:将用请水选净的纯种,用开水(90℃)浸泡,至开水冷却、有少数种子裂口时止。再将种子与冰块混合(比例1:2),进行低温处理三天。然后
In order to shorten the germination period of Korean pine seeds, we introduced the method of Korean pine seed treatment according to Orerainsky’s book on afforestation and adopted the method of low temperature treatment and temperature-induced germination. After sowing for 22 days, the seeds germinated and got good results. The seeds used are transferred from Heilongjiang Province and introduced in Malcolm County. The altitude of 3100 meters, the average annual temperature of 11.5 ℃, rainfall 739mm. Germination method: Will use pure water to choose pure water, soak with boiling water (90 ℃), to boiled water cooling, when there are a few seed break. The seeds are then mixed with ice cubes (ratio 1: 2) for a low temperature treatment for three days. then
