利用玉米芯替换棉籽壳栽培金针菇效益分析

Cultivation of Flammulina velutipes Using Corn Cobs

为探讨在半地下式菇棚中利用玉米芯栽培金针菇(Flammulina velutipes)的可行性,在金针菇主产区(河北省灵寿县)开展了玉米芯部分替换棉籽壳栽培金针菇试验。结果表明:玉米芯替代常规培养料(80%棉籽壳、20%麸皮,另添加1%石灰)中30%棉籽壳用于栽培金针菇菌株苏6,与常规栽培料相比,利润率相近,但生物转化率低(差异达0.05水平);较替代比率为40%和50%效果好。

Flammulina velutipes was cultivated on a series of substrates in which a corresponding amount of the cotton seed hull component, normally constituting 80 parts of the basic formula together with 20 parts wheat bran and 1 part lime, was replaced by 30, 40 or 50 parts corn cob meal, respectively. Biological efficiency values on all the test substrates were lower compared with that recorded on the basic substrate, although little difference was recorded in the overall economics between the test substrate containing 30 parts corn cob meal and the basic formula.
