麦草资源丰富、来源广泛,用麦草栽培平菇各地均有报道。但多数采用培养料高压灭菌或者堆制发酵并添加多菌灵等农药来实现,费时费工,能源消耗多,劳动强度大,且农药残留严重。也有人曾用麦草生料栽培平菇,但因添加氮源,使培养料污染严重而导致失败,或因之而不敢添加氮源结果使平菇产量不甚理想而放弃。本文通L_9（3~4）的正交试验,对麦草生料栽培平菇技术进行初步探讨,现将结果报道如下。1 材料与方法1.1 供试验菌株 F法（原代号SOMYCEL 3032）,学名 Pleurotus ostreatus来源于法国。1995年3月由丹麦哥本哈根大学农学院引入我国。1.2 试验设计 该试验是一个L_9（3~4）的正交试验,其因子及水平组合排列如下表1所示。培养料基本配方为麦草85％、玉米粉15％,培养料含水量70％,pH值8～9,每袋装培养料干重350g。于1996年10月 4日进行。
Wheat grass is rich in resources, extensive sources, with mushrooms cultivated mushrooms have been reported throughout. However, most of them adopt culture material autoclaving or stacking fermentation and add pesticides such as carbendazim to achieve time-consuming and labor-intensive, energy-intensive, labor-intensive, and serious pesticide residues. Some people have also used raw materials of wheat straw mushroom cultivation, but because of the addition of nitrogen sources, the culture material pollution caused serious failure, or as a result of dare to add nitrogen results in the production of less than ideal mushrooms and give up. In this paper, L_9 (3 ~ 4) orthogonal experiment, the raw straw mushroom cultivation technology preliminary study, now the results reported below. 1 Materials and methods 1.1 for test strains F method (original code SOMYCEL 3032), scientific name Pleurotus ostreatus from France. March 1995 by the Danish University of Copenhagen Agricultural College into China. 1.2 Test Design The test is an orthogonal test L_9 (3-4), the factors and the level of the combination of the arrangement shown in Table 1 below. The basic formula of training material is 85% wheat straw, 15% corn flour, 70% moisture content of culture material, pH value of 8 ~ 9, dry weight of bagging culture material 350g. On October 4, 1996.
