飞播质量的高低,直接关系到种子和幼苗分布的匀度及飞播效果。而飞播质量又受天气(主要是风速、风向)、地形、机型、播种设备、播幅与作业航高以及种子容重等因素的影响。其中,播幅大小是影响飞播质量的重要因素之一。
The quality of aerial seeding is directly related to the distribution of seeds and seedlings and the effect of aerial seeding. And the quality of aerial seeding is influenced by such factors as weather (mainly wind speed, wind direction), topography, model, seeding equipment, sowing height and operation altitude as well as seed weight. Among them, sowing size is one of the important factors affecting the quality of aerial seeding.
