近年来,我们在研究凤尾菇栽培技术的同时,还开展了下床培养料的再利用试验,现介绍如下。一、材料与方法 (一)沼气发酵①瓶装发酵采用10升发酵瓶,投料80％,干物质含量14％。用料配比设四个处理:a.稻草625克(对照);b.下床菇料625克;c.稻草+红萍各310克;d.下床菇料+红萍各310克。四个处理均另加猪粪1875克,种子液2500毫升、水3000毫 In recent years, we study the Pleurotus ostreatus cultivation techniques, but also carried out out of bed culture materials re-use test, are presented below. First, materials and methods (A) biogas fermentation ① bottled fermentation using 10 liters fermentation flask, feeding 80%, dry matter content of 14%. The ratio of materials used to set the four treatment: a straw 625 grams (control); b. Out of bed mushrooms 625 grams; c straw + red ping the 310 grams; The four treatments plus pig manure 1875 grams, seed solution 2500 ml, water 3000 milliliters
