平菇栽培中的主要问题之一是菌种生产时间长,成本高.为了解决这个问题,山东省农业科学院土壤肥料研究所微生物室食用菌组于1982年承担了省科委下达的液体菌种研制任务。在卢青达同志的主持下,经过三年又三个月的试验,试验成功了节能简易液体发酵设备和拌料机,并完成了液体菌种小型生产工艺,使平菇原种的培养对间从30天缩短至3～5天,栽培种的培养时间也从30天缩短至15～18天.液体发酵的操作技术大大简化.不需要日夜值班.栽培种月产量可达0.6～1.0万个罐头瓶容量.生产工艺简便容易掌握,而设备投资只需3200元.建一个车间,设备投资5000～6000元,产量可增加两倍.即月产栽培种可相当于3万个罐头瓶容量。每公斤栽培种的生产成本为0.2～0.3元。设备费比不锈钢发酵罐节省
Mushroom cultivation is one of the major problems of strain production for a long time, high cost.In order to solve this problem, Institute of Soil and Fertilizer Institute of Shandong Province microbial chamber edible fungi group in 1982 assumed the provincial science and Technology Commission issued liquid strains Development task. Under the leadership of Comrade Lu Qingda, after three years and three months of trial, the successful trial of energy-saving simple liquid fermentation equipment and batching machine, and completed a small liquid bacterial species production technology, 30 days shortened to 3 to 5 days, cultivating cultivation time from 30 days to 15 to 18 days. Liquid fermentation operation greatly simplified technology. No day and night on duty. Cultivation of monthly production of up to 0.6 to 10 million cans Bottle capacity.Easy to master the production process, and equipment investment is only 3200 yuan.With a workshop, equipment investment 5000 ~ 6000 yuan, the output can be doubled.That is monthly production of cultivars can be equivalent to 30,000 cans of bottle capacity. The cost per kilogram of cultivated species is 0.2 to 0.3 yuan. Equipment costs less than stainless steel fermentors
