Abstract:This paper discusses the different species of Pleurotus eryngii the growth characteristics, yield and nutrient composition of the initial analysis. Experimental results show that different species Pleurotus eryngii growth conditions are different, the same culture conditions, Pleurotus eryngii varieties fruiting body morphology and yield is obviously different. Experimental selected through a high quality of Pleurotus eryngii 2 (cited in Zhejiang Academy of Agricultural Sciences) and the more ideal training materials formula : Sawdust 30%, 46.5% cotton seed hulls, wheat bran 18%, 3% of corn powder, sugar, 1%, 1% Gypsum, Lime 0.5% of. Four types of Pleurotus eryngii Fruitbody (dry goods) of amino acids and other nutritional components of the analysis, The results showed Pleurotus eryngii contains 17 kinds of amino acids (L - tryptophan unmeasured), a rich eight essential amino acids, Branched - chain amino acids and with the guanidine-arginine, and the aromatic amino acid content is low, arginine, Glutamate closer to a content - casein protein, egg protein and soybean globulin content.
