油松(Pinus tabulaeformis carr)是我国暖温带半湿润地区飞播林效果最好的树种,也是华北山地有代表性的先锋造林树种。由于飞机播种后种子裸露地表,所以种子的萌发、幼苗的成活、生长,完全依赖自然因素。若用水浸种催芽,以及用硝酸钾,过氧化氢对种子进行处理虽然均能提高种子的活力,达到提高发芽率、发芽势之目的,但不适宜飞播, Pine (Pinus tabulaeformis carr) is one of the most effective species for aerial seeding in warm temperate semi-humid areas in China, and is also a pioneering afforestation species in northern China. Due to the exposed surface of the seeds after sowing the aircraft, seed germination, seedling survival, growth, completely dependent on natural factors. If the seed soaking with water, as well as the use of potassium nitrate, hydrogen peroxide, seed treatment can improve the seed vitality, to improve the germination rate, the purpose of germination potential, but not suitable for aerial seeding,
