Abstract

The effect of wheat straw mix was tested to develop rice straw replacement media. The chemical contents were analysed after late fermentation. Nitrogen content and C/N ratio of the 20% wheat straw mixing medium were 2.2% and 16.7 and the only rice straw using medium were 2.0% and 17.9, respectively. When the 20% wheat straw mixing treatment was compared to the only rice straw medium, pinhead initiation period was shortened and the yield was increased as much as 30%. Therefore the 20% wheat straw mixing medium is expected to replace the rice straw medium.

볏짚 대체 배지를 개발하기 위해 밀짚 혼용 비율에 따른 볏짚 대체 효과를 구명한 결과는 다음과 같다. 후발효 배지의 화학적 성분을 분석한 결과 밀짚을 20% 혼용한 배지의 질소 함량과 C/N율은 각각 2.2%와 16.7이고, 볏짚 단용 배지는 2.0%, 17.9로 조사되었으며, 볏짚 단용 배지보다 초발이소요일수가 빠르고, 수량도 30% 증수되어 대체 효과를 기대할 수 있었다.
