【 摘 要 】

Recently, organic cultivation is attracting attention. However, the technique for raising paddy rice seedlings using organic fertilizer has not been established. We developed a technique for raising organic seedlings under the pooled condition using forest surface soil in the nursery boxes. In a preliminary experiment, we examined three kinds of organic fertilizers, rapeseed oil cake, fish grounds and feather meal. The results suggested that the rapeseed oil cake mixed with fish grounds is the most effective. Then, we mixed the rapeseed oil cake and fish grounds at a ratio of 1 to 1 in N content and set up four plots containing 0,1,2 or 3 grams nitrogen in each nursery box. We concluded that mixing the rapeseed oil cake containing one gram nitrogen with fish grounds containing one gram nitrogen (2 grams of nitrogen in total) was appropriate for raising paddy rice seedlings under the pooled condition with forest surface soil in the nursery box.
