在降水量丰富的地区,不经处理的油松种子飞播效果尚好,但在干旱地区或少雨年分,就势必影响飞播效果,特别是干旱少雨的西北内陆,就更是如此。为探索降水偏少、生长期短的地区提高飞播效果的途径,我们用经过催芽的油松种子做了飞播模拟试验,取得了较好的效果。 In areas with abundant rainfall, the untreated pine seeds are still good, but they are bound to affect the effects of airborne seeding in arid areas or in a few rainy days, especially in the arid and inhospitable northwest China. In order to explore ways to increase the effect of airborne seeding in areas with less precipitation and short growth period, we used the primed Pinus tabulaeformis seeds to do the aerial seeding simulation and achieved good results.
