Development of Paste Fertilizer for Rice -II. Effect of Paste Fertilizer on Rice

기계시비(機械施肥)가 용역(容易)한 반액체상(半液體狀)인 수도기비용(水稻基肥用) 호상비료(糊狀肥料)를 개발(開發)하여 이앙기(移秧機)에 부착(附着)된 시비기(施肥機)를 통하여 측조국지시용(側條局地施用)으로 태백(太白)벼와 천마(天磨)벼를 공시(供試)하여 비효시험(肥效試驗)을 실시(實施)한 결과(結果)는 다음과 같다. 수량(收量)은 시제품(試製品) 처리구(處理區)에서 분벽비(分蘗肥) 20%(N)를 감(減)하여도 감소(減少)되지 않았으며 생육상황(生育狀況)은 시제품구(試製品區)가 대조구(對照區)에 비하여 초기생육(初期生育)은 양호(良好)하였으나 후기생육(後記生育)은 큰 차이(差異)가 없었으며 태백(太白)벼, 천마(天磨)벼 공(共)히 같은 경향(傾向)이었다. 식물체중(植物體中) 질소성분함량(窒素成分含量)은 생육초기(生育初期)에는 시제품구(試製品區)가 대조구(對照區)보다 높았으나 후기(後期)에는 뚜렷한 경향(傾向)이 없었다.

This study was conducted to evaluate the effect of a newly developed paste fertilizer on rice growth. It was applied to two vars. of Taeback and Cheonma byeos as a basal treatment. It needs a unique applicator attached to transplant machine for rice plant and was injected about 3cm depth of paddy soils. The polished rice yields were obtained competitively with a 20 percent reduction of N applied with top dressing. Plant development treated paste fertilizer was good compared to control at the early growing stage, however, not different at the late growing stage. Nitrogen uptake in plant was high at the early growing stage in paste fertilizer treatment but there were no significant difference at the late growing stage.
