Nutritional Evaluation and Benefit Analysis of Pleurotus eryngii Cultivated on Casing Soil
The nutritional composition(protein,amino acids,fat,etc.)of soil-covering cultivation and factory-cultivated Pleurotus eryngii,as well as the nutrient content of the soil before and after cultivation,were compared.The feasibility of soil-covering cultivation-P.eryngii residue return-food/fruit/vegetable rotation planting model in winter fallow fields was explored by calculating the input-output efficiency of soil-covering cultivation.The results showed that the content of protein,fat,amino acids,etc.in the fresh fruiting bodies of soil-covering cultivation P.eryngiis was higher than that of factory-cultivated.The protein content of P.eryngii at different maturity stages was different,with the highest content in the early stage of maturity,reaching 4.19 g/100 g,which was 1.3 times that of the mature stage,1.6 times that of the spore release stage,and 1.9 times that of the factory-cultivated.The content of essential amino acids and flavoring amino acids in soil-covering cultivation P.eryngii was also higher than that in factory-cultivated,and the E/T value was close to the high-quality protein amino acid composition value proposed by FAO/WHO.After returning mushroom residue to the soil,the soil organic matter content was increased by 116％ .The biological conversion rate of soil-covering cultivation was 136％,and the input-output ratio was 1∶1.8.Soil-covering cultivation P.eryngii cultivated in winter fallow fields are rich in nutrients,have a delicious taste,and have good economic benefits.Returning mushroom residue to the soil can increase the soil organic matter content and is suitable for promotion and application in winter and spring in the main rice-producing areas in the south.
