用棉籽壳栽培平菇,一般都要添加1%白糖,也有用3%煮熟去皮的马铃薯代糖。为了降低成本,笔者从1983年开始就地取材,用鲜红薯(山芋)试种6米~2代糖栽平菇试验,收到了较好效果。(每米~2用干棉籽壳20公斤),收鲜菇115.5公斤,生物学效率为96.2%;1984年试种18米~2,收鲜菇387公斤,生物学效率达107.5%,可与添加白糖、马铃薯的常规栽培产量媲美。现将具体做法介绍如下。
Mushroom cultivation with cottonseed shells, generally have to add 1% sugar, but also useful 3% cooked peeled potato substitute sugar. In order to reduce costs, the author started from 1983 on the spot, with fresh sweet potato (potato) 6m ~ 2 generations of sweet potato planted test, received good results. (Per kg ~ 2 with a dry cottonseed shell 20 kg), close to 115.5 kg of fresh mushrooms, the biological efficiency of 96.2%; 1984 test 18 m ~ 2, received fresh mushrooms 387 kg, the biological efficiency of 107.5% Add sugar, potato cultivation yield comparable to conventional. Specific practices are introduced below.
