为了提高稻草栽培平菇的生物学效率,几年来笔者对平菇的营养生理和稻草的处理进行了探索,收到了较好效果,现简报如下:(一)菌株选育与基质配制供试菌种是我校野生驯化种经多年连续单株组织分离选育的“新平”菌株.原种是谷粒培养基,谷粒98%,石膏粉2%,常规法接种培养.栽培种是木屑培养基,木屑77%,糖1%,纸浆废液1%,糠或麦麸20%,石膏粉1%,常规法接种培养,菌丝长满瓶(袋)后5天接栽培种.栽培料配方为稻草86%、糠8%、草木灰3%、食盐2%、石膏粉1%、尿素0.3%、pH值9,含水量65～72%.
In order to improve the biological efficiency of straw-growing Pleurotus ostreatus in recent years, the author of the nutrition physiology and straw treatment were explored and received good results, are presented as follows: (A) strain selection and matrix preparation for the test bacteria The species is the “Xinping” strain of wild domesticated species that has been isolated and cultured for many years in a row in a single plant in China. The original species is a grain culture medium containing 98% of grain and 2% of gypsum powder. Sawdust medium, sawdust 77%, sugar 1%, pulp waste 1%, bran or wheat bran 20%, gypsum powder 1% conventional culture inoculation, mycelium grow bottles (bags) 5 days after planting. Cultivated material formula is straw 86%, bran 8%, ash 3%, salt 2%, gypsum powder 1%, urea 0.3%, pH 9, water content 65-72%.
