摘要
研究了多菌灵、氢氧化铜、代森锰锌和百菌清 4种杀菌剂对糙皮侧耳菌丝生长和子实体产量的影响及控制霉菌污染的效果。结果表明 ,不同种类杀菌剂及同一种杀菌剂不同使用浓度对糙皮侧耳菌丝生长、产量及霉菌污染程度的影响存在显著差异。其中以 0 .6 6 7g/L～ 0 .883g/L的氢氧化铜对糙皮侧耳菌丝生长的抑制作用最小 ,抑制率小于 6 % ,与对照无显著差异 ,并能完全控制霉菌的污染 ,使生料块栽糙皮侧耳的产量提高 30 %～ 4 0 %。
The effects of four fungicides on the mycelial growth, the yield of Pleurotus ostreatus and the mold contamination controlling ability were studied. It was showed in our experiments that the effects of different kinds of fungicides and different concentrations of the same kind of fungicide used had significant differences. And it was also proved in our experiments that copper hydroxide at the concentration of 0.667g/L～0.883g/L had the least average inhibitory rate of lower than 6%, with no significant difference to the contrast, for the mycelial growth of P.ostreatus and could completely inhibit the growth of contaminated mold with an yield increment rate of 30%～40% for P.ostreatus cultivated by raw compost block. Therefore, copper hydroxide, with the concentration of 0.7g/L～0.9g/L,was considered to be the optimum fungicide to extend in the cultivation of P.ostreatus.
