平菇高产栽培麦草配方数学模型与优化

采用回归正交设计,研究麦草栽培平菇的配方组合与平菇产量之间的数量关系,建立了数学模型。结果表明,以麦草为主料,各组分的合适用量,以及它们之间的一定组合关系,可使产量大幅度提高,并具有较好的稳定性。同时提出了麦草栽培平菇的最优配方方案为:麸皮:玉米面:尿素:麦草:硫酸镁:过磷酸钙=15:5～7.27:0～0.3:75～85:0.0183:1.这在生产实践中很有应用价值。

Mathematical Model and Optimum Formula of High Yielding Cultivation of Pleurotus osturatus with Wheat Straw

This paper adopts the rotatable second order design to study the numerical relation between the formula cultivation of Pleurotus ostre-atus with wheat straw and the yield of Pleurotus ostreatus, and to establish their mathematical model. The results show that the yield can be highly improved with better stability using wheat straw as main material, with the optimum quantity of every composition and in certain integrating relation of them, it also suggests an optimum formula with the ratio of wheat bran to corn-meal to urea to wheat straw to MgSO4 to CaSO4 Ca3 (PO4) 2 are 15 to 5-7.27 to 0-0.3 to 75-85 to 0.0183 to 1. This is very applicable to practical production activities.
