Description

TECHNICAL FIELD

[0002] Pepper seed pelletization technology is developed on the basis of seed coating technology, which changes the volume and shape of pepper seeds by wrapping a layer of degradable or soluble filler on the surface of pepper seeds, so as to make small seeds large, light seeds heavy, and irregular seeds regular, thereby helping to realize the mechanization and precision seeding of pepper seeds.

[0003] The protective film on the outer layer of the pepper seed can prolong the life of the seed, maintain the humidity of the seed, and promote the germination and growth of the seed. However, the protective film is also prone to breakage during the seeding process. There are two common seeding methods for pepper pelletization seeds in the prior art: one is manual quantitative seeding, which improves the seeding efficiency compared to the traditional method of first growing seedlings and then transplanting, but the efficiency is still low; the second is to use a seeding machine, but the existing seeding machine is not specifically designed for pepper pelletization seeds, and has problems such as high seed coating breakage rate and inability to adjust the ridge spacing when applied to pepper pelletization seeds.
