<P>PROBLEM TO BE SOLVED: To develop direct sowing cultivation technique which can ensure the equivalent or higher germination and plant establishment, and early growth of coated seeds to or than those of conventional coated seeds containing calcium peroxide, and which provides coated sddes harf to suffer bird damate. <P>SOLUTION: The coated seed is obtained by alternately repeatedly forming a coating layer containing carbon and a coating layer containing calcium peroxide on the surface of the seed such as rice. The brightness of the seed surface layer can be lowered to the approximately same degree of soil by covering the seed with the carbon, and the bird damage can be avoided or largely relaxed. The cost of a material added can also be reduced. In addition, the germination and budding of the seed are more promoted than seeds using conventional materials, and the outflow of seeds and the generation of floated seedlings and fallen seedlings can be reduced to enhance the rate of the stand establishment of the seedlings. <P>COPYRIGHT: (C)2012,JPO&INPIT |
