为了发展养猪事业和饲料生产,我们在开门办科研中结合利用微生物提高粗饲料营养价值研究的作务,从我省大面积栽培蘑菇的实际出发,对蘑菇糠的资源、价值、加工、发酵和喂猪效果进行了多点实验和调查研究,取得了初步结果。一、蘑菇糠的资源调查:蘑菇糠是指收完菇,取走复土后,剩下长满蘑菇菌丝的培养料,经过晒干粉碎而制成的粉状物。据福州、莆田、晋江、龙溪四个地区统计,一九七四年栽培蘑菇面积达5000万平方尺,近年更加发展。我们按此测算,每年可以拿到5万吨以上的干蘑菇糠。这相当于全省全年供应统糠数量的三分之一。由于蘑菇糠在四、五月间出货,正是 In order to develop the pig raising business and feed production, we combine the research work of using microorganisms to improve the nutritive value of roughage in door-opening scientific research. Based on the actual situation of large-area cultivation of mushroom in our province, we analyzed the resource, value, processing, Feeding pigs conducted a number of experiments and investigations, and achieved initial results. First, the mushroom chaff resources survey: Mushroom bran means harvesting mushrooms, remove the compound soil, the rest of the mushroom material covered with mushrooms, dried and crushed and made of powder. According to the statistics of Fuzhou, Putian, Jinjiang and Longxi, in 1974, the area of ​​cultivated mushrooms reached 50 million square feet and was further developed in recent years. According to this measure, we can get more than 50,000 tons of dried mushroom bran each year. This is equivalent to one third of the whole country’s supply of chaff. Because mushroom bran is shipped in April and May, exactly
