近几年栽培平菇多以废棉和棉籽皮作培养料,这两种培养料虽然产量高,但随着各地栽培面积的不断扩大,原料普遍供不应求,而且价格上调,提高了生产成本。为适应平菇生产的需要,我们进行代料栽培平菇的试验,收到较好效果。代用料选用来源广泛、成本较低的玉米芯,玉米芯加王米秆,玉米芯加豆秆,玉米秆四种配方;以废棉为对照。结果证明,废棉培养基的产量稍高于代用料培养基,但净效益不如代料栽培。如在代用料中加入适量的麦麸或玉米面,效果会更好。
In recent years, many cultivated mushrooms use waste cotton and cottonseed husk as the cultivation material. Although the two kinds of cultivation materials have high yield, as raw materials are generally in short supply due to continuous expansion of cultivation areas, the production costs are raised. In order to meet the needs of the production of Pleurotus ostreatus, we carry out the test of planting Pleurotus ostreatus and receive good results. Substitute materials used a wide range of sources, lower cost corn cob, corn cob plus Wang rice straw, corn cob plus bean stalks, corn stalks four formulations; waste cotton as a control. The results showed that the yield of waste cotton medium was slightly higher than that of substitute medium, but the net benefit was not as good as that of substituting material. Such as substituting the appropriate amount of wheat bran or cornmeal, the effect will be better.
