Abstract
In order to ascertain the effects that a coating method of rice seeds with calcium peroxide have influence on the properties of the coated seeds, a mass ratio of atomized water to calcium peroxide was investigated, using two kinds of calcium peroxide. The test results show that, in order to have uniform coated rice seeds and a balanced coating process, a mass ratio of atomized water to calcium peroxide of 22.8% was necessary. The correlation between the mass of the coated rice seed and its cubic volume or hardness was very linear, and the germination rate of coated rice seeds was low due to their high level of hardness. As a result, the germination rate of coated rice seed was restricted by its mass to below 80mg with "Calper A" calcium peroxide, and to below 90mgwith "Calper 16", and a hardness of 9.6N.
