玉米芯作为杏鲍菇栽培原料的可行性研究

Feasibility study on corncob as raw material for cultivation of Pleurotus eryngii Quel.

以甘肃省丰富的玉米芯和玉米芯发酵料为栽培主料,以玉米面、麦麸、高粱壳等为辅料,探索不同主料以及不同基质配比对杏鲍菇(Pleurotus eryngii Quel.)产量及生物学转化率的影响,结合经济效益分析,筛选出了适合杏鲍菇生产的最佳培养料配方。结果表明,利用玉米芯为主料或以玉米芯添加高粱壳的培养基均可以获得杏鲍菇较好的出菇特性,而其中以配方Ⅴ处理(玉米芯40%、高粱壳48%、玉米面10%、石膏粉2%、基质含水量65%)为最佳栽培基质配方,菌丝生长速度最快,可达到0.48 cm/d,子实体产量高,生物转化率可达93.82%。

The corn cob and the corn cob fermentation material in Gansu were used as a cultivation main material, taking corn flour, wheat bran, sorghum shell and the like as auxiliary materials,the effects of different main materials and different matrix ratios on the yield and biological conversion rate of Pleurotus eryngii Quel. were studied. Combining with the economic benefit analysis, the best culture formula suitable for the production of Pleurotus eryngii Quel. was selected. The results show that using corncob as the main material or adding sorghum shell to corncob as the medium, we could obtain the better mushroom characteristics of Pleurotus eryngii Quel., and the formulation Ⅴ(corncob 40%, sorghum shell 48%, corn flour 10%,gypsum powder 2%, substrate moisture 65%) as the best cultivar matrix formulation, the growth rate of the hyphae is the fastest, and the growth rate of the hypha could reach 0.48 cm/d, the yield of the fruiting body is high, the biological conversion rate could reach 93.82%.
