Abstract

The highest fresh weight of Agaricus bisporus was obtained at pH 7.5 of casing soil. Above or below this pH level, the yields were significantly reduced. Stimulatory effect of calcium on the mycelial growth depended upon pH of casing soil, In neutral or slightly alkaline soil, the stimulatory effect was increased. The effects of supplementing calcium carbonate or hydrated lime to casing soil were assumed not only the influence of pH of casing soil, but also stimulatory effect of calcium ion on mycelial growth of A. bisporus.

양송이를 재배할 때 복토의 최적 pH와 칼슘원의 효과를 구명코저 본 시험을 실시하였다. 양송이 복토의 최적 pH는 7.5이었다. 중성내지 약알카리성토양에서 칼슘의 촉진적 효과가 뚜렷하였다. 즉, 복토에 첨가되는 수산화칼슘 및 탄산칼슘의 효과는 pH교정뿐만 아니라 칼슘의 생장촉진효과도 중요하다고 본다.
