Optimum mixing rate of used media for saving the production cost of Flammulina velutipes

팽이버섯(Flammulina velutipes) 생산비 절감을 위한 폐배지 적정 혼합비율

These experiments were conducted to find the optimum mixing rate of used media for saving the production cost of Flammulina velutipes. The materials for media formation was used needle-leaf tree sawdust, media that finished 1th cultivation of F. velutipes, corncob meal, and rice bran, wheat bran as nutrition source. We inoculated the F. velutipes in 14 kinds of different media types and checked the spawn growth speed, fruit body quality and quantity. Two nutrition agents, which is rice bran and wheat bran, did not affected the incubation period, but the effective stem number, quality and quantity of fruit body was better at rice bran than wheat bran. The quality of fruit body produced at mixed 20% of used media (needle-leaf tree sawdust 60% + used media 20% + rice bran 20%) was similar to control plot (needle-leaf tree sawdust 80% + rice bran 20%), but the yield was improved 10% than control plot 130g. According as the used-media mixing amount increases, quality and quantity of fruit body became low remarkably. Therefore, the optimum mixing amount of used-media was 20% and it increased 10% of fruitbody yield.

팽이버섯 생산비용을 절감하기 위하여 한번 사용한 배지의 적정 혼합비율을 구명하고자 시험한 결과는 다음과 같다. 팽이버섯 재배 배지재료로 미송톱밥, 1회 팽이버섯 재배에 사용한 톱밥, 콘코브 그리고 영양원으로 미강과 밀기울을 이용하여 14가지로 배지를 조성하여 균사배양기간, 자실체 수량과 품질을 조사하였다. 두 가지 영양원에 따라 배양기간은 큰 차이가 없었지만 유효경수, 자실체 수량과 품질은 밀기울보다 미강이 좋았다. 폐배지를 20% 혼합한 처리 즉 미송톱밥 60%+폐배지 20%+ 미강 20% 배지가 관행처리 미송톱밥 80%+미강 20% 배지와 품질은 비슷하며 수량은 142.2g 으로 관행의 130g 대비 10% 증수하였다. 그러나 폐배지 혼입량이 증가함에 따라 자실체의 품질과 수량이 현저하게 감소하였다. 따라서 폐배지의 적정 혼합량은 20%이며 수량도 10% 증가하였다.
