土废棉绒是棉花加工厂脱绒与压花车间的废弃物,它由棉短绒、棉籽壳、棉籽仁的碎粒与粉末、棉花叶、僵瓣和尘土等组成。就我省来说,年产皮棉2000万担,土废绒约有30万担。为了开发食用菌培养料的资源,我们从1982年开始利用土废绒栽培平菇的试验,经多次重复,获得了较好的效果,每斤土废绒可产鲜平菇0.63～0.95斤。现将1982～1983年的试验结果报导如下。 Waste cotton linter is a cotton processing plant off the cashmere and embossing workshop waste, which consists of cotton linters, cottonseed shells, cottonseed kernels and granule powder, cotton leaves, stiff petals and dust and other components. For our province, with an annual output of 20 million lint of cotton, soil waste about 300,000 Tam. In order to develop the resources of edible fungus culture material, we started to use the experiment of culturing edible mushrooms with edible weeds from 1982, and obtained the better results after repeating many times. Each ewe waste soil can produce 0.63 ~ 0.95 pounds of fresh Pleurotus ostreatus . Now 1982 ~ 1983 test results reported below.
