飞播造林具有速度快、区域广、省工省力的优点,但种子处理不当,会影响到飞播造林的效果。1种子选择为了保证种子的发芽率与生长健壮,必须对种子进行必要的选择。用专用的风机对种子进行风选,发育得不好的、相对较轻一些种子被吹得远一点,种皮会吹得更远一些,而那些发育饱满的种子是不会吹远的,利用这个原理,可以将劣质的、种皮等物质筛选出来。
Aerial seeding afforestation has the advantages of fast speed, wide area and labor-saving. However, improper seeding will affect the effectiveness of aerial seeding and afforestation. 1 seed selection In order to ensure the seed germination and robust growth, the seeds must be the necessary choices. With a dedicated fan of the wind on the election, the development is not good, relatively light Some seeds are blown farther, the seed coat will blow some farther, and those full of seeds will not blow away, the use of This principle, you can inferior, seed coat and other materials selected.
