Coated seed and process for producing the same |
摘要 |
The present invention is characterized by coating a seed with from 0.1 to 25% by weight of a powder (A) composed of one or both of montmorillonite and bentonite and having an average particle diameter of 30 mu m or less and from 99.9 to 75% by weight of a powder (B) composed of a material other than montmorillonite and bentonite and having an average particle diameter of at least 10 mu m and at most 30 mu m using a polyvinyl alcohol aqueous solution having an aqueous solution viscosity at 25 DEG C of 50 mPa.s or less as a binder. Consequently, a coated seed obtained by coating a seed, especially a light-favoured seed, easily absorbs water in sowing and is easily cracked in absorbing water. Further, the easy cracking thereof remains unchanged with the course of time. In the coating, formation of by-product seedless spherical pellets is little observed. |
