Abstract

In order to establish the application method of slurry composting & biofilteration liquid fertilizer (SCB LF) in rice cultivation, experiments were studied on split application method of it and effects of it on soil chemical properties and rice yields. Land leveling by rotary tillage within 2 days after application of SCB LF, $NH_4$-N concentration in soil was maintained uniformly in all paddy field. Initial concentrations of $NH_4$-N and $NO_3$-N in soil were high at standard fertilization and 100% application of SCB LF as basal fertilization, however, after tillering stage they maintained similar concentrations in all experimental plots. $NO_3$-N content in infiltration water was slightly lower at 70% application of SCB LF as basal fertilization and 30% application of SCB LF as fertilization at panicle initiation stage than at standard fertilization. Yields of rice by split application of SCB LF were lower at 100% application of SCB LF as basal fertilization, however, those of the other application of SCB LF were similar with that of standard fertilization. In case of rice quality, perfect kernel rates were high and protein contents were lower at non-application and 100% application of SCB LF. Rice quality of 70% application of SCB LF as basal fertilization and 30% application of SCB LF as fertilization at panicle initiation stage were similar with that of standard fertilization.

벼에 대한 SCB 액비의 활용방법을 구명하기 위하여 기 추 비 시용량을 달리 처리한 후 쌀 수량 및 토양환경에 미치는 영향 등을 검토한 결과는 다음과 같다. 논토양의 화학성은 규산을 제외한 액비시용구가 무시용구에 비하여 높았으나 시험 전 후 간에는 큰 차이가 없었다. 액비시용 후 토양 중 $NH_4$-N함량은 2일 이내 균평작업으로 논 전체에 균일한 농도를 유지하였다. 액비분시에 따른 토양 중 $NH_4$-N와 $NO_3$-N함량은 이앙 후부터는 초기에는 화학비료 관행시비구와 액비 기비 100%처리에서 높았으나 분얼감수기 이후에는 모든 처리가 유사하였다. 토양침출수중 $NO_3$-N함량은 액비기비70%+수비30%시용에서 관행시비구보다 약간 낮은 함량을 보였다. 액비 분시에 따른 쌀 수량은 관행시비구보다 액비 기비 100%처리에서 약간 낮았으나 액비 기비70%+수비30%에서 관행시비구와 대등하였으며 나머지 액비 처리구에서도 큰 차이가 없었다. 쌀 품위는 무 시용구와 액비 기비100%에서 완전립율이 높고, 단백질함량이 낮았으나 액비기비70%+수비30%에서 관행시비구와 유사하였다. 따라서 SCB액비를 이용하여 벼 재배할 경우 액비기비70%와 수비30%시용으로 화학비료 사용을 대체 할 수 있을 것으로 판단된다.
