초록

환경보전형 시비기술 개발을 목적으로 화학비료의 사용을 절감하는 한편 화학비표를 유기질비료로 대체 사용하는 방법을 구명코자 호남평야지 대표 토양인 전북통에서 2년간('99~'00) 동안벼를 공시하여 어린모 기계이앙으로 재배하였고 시비방법으로 관행(표준시비), 완효성비료(LCU) 40%를 전량기비 후 수비로 출수 30일전에 채종유박시용량을 10, 30, 50%시용구와 질소무시용구 등 5처리 하여 수행한 시험결과는 다음과 같다. 공시된 채종유박의 질소 무기화율은 72.4%였으며 전질소함량은 5.3%였다. 시험후 토양의 화학성은 관행에 비하여 유박시용구에서 pH, 유기물함량 등이 증가되었으나 칼리와 고토함량은 일정한 경향이 없었다. 시비질소의 토양중 $NH_4-N$ 발현량은 이앙 후 18일까지는 LCU시용구 보다 관행구에서 높았으나 최고분얼기 이후부터 상반되었고 출수기에는 수비유박 대체량이 많을수록 높아 졌다. 수량은 관행에 비하여 완효성비료 (LCU)40% 기비 시용후 유박시용량이 증가할수록 증수하였는데 유박을 수비로 30%시용시 2%, 50%시용시 4% 증수되었으며, 증수요인은 $m^2$당 립수의 증가에 있었다. 한편 시비질소 흡수량은 관행에 비하여 수비유박의 시용량이 증가 할수록 많았으나 질소이용율은 수비로 유박을 50%시용한 처리보다 30%시용한 처리에서 높게 나타났다. 따라서 관행의 수비요소를 유박으로 30%까지 대체할 경우 비료 절감측면이나 질소 이용효율 면에서 유리할 것으로 판단되었다.

A field experiment was conducted to investigate the effect of N-use efficiency and rice yield by rapeseed cake(organic fertilizer) application at panicle initiation stage in machine transplating cultivation from 1999 to 2000. The rice yield increased by 4% in "50% rapeseed cake application", by 2% in "30% rapeseed cake application" at panicle initiation stage, respectively. Amount of fertilizer N uptake was high according to increasing amount of rapeseed cake application at panicle initiation stage compared with conventional treatment, but percentage recovery of fertilizer N was higher in 30% rapeseed cake application than in 50% rapeseed cake application at panicle initiation stage. Thus, this result was thought that there was more adventageous in 30% rapeseed cake application than 50% rapeseed cake application at panicle initiation stage in the fertilizer reduction or N-use efficiency respects in rice paddy.
