飞播造林最显著的特点,是用飞机把种子撒播在地表,靠自然因素使种子发芽和幼苗成活生长。在播区、树种、播期均适宜的情况下,撒下的种子如能及时遇到适当的水、热条件,种子即可顺利经过吸胀、萌动、发芽的过程而成活;如果撒下的种子一时遇不到适当的水、热条件,种子就容易遭受损失,飞播也常因此造成失败。可见,保护好撒在地表面的种子使其不受损失,是提高飞播效果的重要因素。
The most significant feature of aerial seeding is the use of airplanes to sow seeds on the earth’s surface and seed germination and seedling growth by natural factors. In the broadcast area, tree species, sowing date are appropriate circumstances, the seeds sown if they can meet the appropriate water and heat conditions, the seeds can be smoothly through the imbibition, germination, germination process and survive; if sown Seeds sometimes fail to meet the appropriate water, heat conditions, the seeds are vulnerable to losses, air seeding is often caused by failure. It can be seen that protecting the seeds scattered on the ground from being lost is an important factor in improving the effectiveness of the air-to-air transmission.
