The Study Of High-yield Technology And Nutritional Utlization For The Cultivation Of Agaricus Bisporus In Maize Straw

This paper studied the high-yield technology using maize straw as the stuff for the cultivation of Agaricus bisporus, screened the high-yield prescription of the substrate containing maize straw .appraised and analysized the productive properties of three kinds of Agaricus bisporus by its cultivated property,yield and nutritional components of fruitbodies,analysized the effects of the XSJ fermentation on the cultivated property and yield in Agaricus bisporus ,and studied the pattern of casing soil using Fussy analysis method of orthogonal experiment design.On the basis of high-yield technology,the paper discussed the law of utilization of nutritional components and the change of extracellular enzyme's activity during its growth in maize straw .The results showed as follows:(1) In Agaricus bisporus cultivation,the mycelial growth principle and the fruitbody growth principle were in accordance with the logistic curve and the exponential growth curve resp.The mycelial growth rate of the substrate containing maize straw was higher than that of the wheat straw substrate. Compared with wheat straw ,the peak fruitbody flush appeared sooner;Its fruiting period was shorter.Using the substrate which proportion of maize straw and cattle dung was 1:1,and cultivating Agaricus bisporus ,the mycelia grew fastest,and biological efficiency was nearly the same as that of the substrate containing wheat straw.(2) In the three kinds of Agaricus bisporus ,the biological efficiency and nutritional components of AS2796 were nearly the same as those of 111, The differences were not significant,but compared with 111 ,the mycelium of AS2796 grew faster and the fruitbody appeared sooner.(3) It was feasible to ferment the substrate using the XSJ fermnentation ,compared with double fermentation,the microflora increased, nutritional components improved, and the quality of the substrate optimized.Therefore,the XSJ fermentation had influence on growth and development of Agaricus bisporus ,the mycelia grew fast, the quality and yield of the fruitbody were well.(4) The time,the properties of material,the thickness of casing soil affected directly the quality and yield of Agaricus bisporus .The material of casing soil of three factors had the greatest effect on the biological efficiency,next the thickness,once more the time.Theoptimum casing soil pattern was the combination of sixteen days after sowing,casing rotten leaf soil and casing four or three point five centimeters.(5) Agaricus bisporus degraded mainly lignose in the mycelial growth and degraded mainly cellulose and hemicellulose in the fruitbody Agaricus bisporus used not only lignocellulose but nonlignocellulose.The activities of enzyme such as cellulose, hemicellulose, laccase and peroxide changed correspondly.
