Abstract

Abstract: 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%.

Key words: Pleurotus eryngii Quel., corncob, substrate formula, cultivation formula, yield
