随着“五四○六”菌肥应用面积不断扩大,菌种粉的生产和供应远跟不上当前农业发展的需要。为了切实做好支农工作,各地创造了多种适合当地生产菌种粉的方法,收到了较好的效果。几年来,我厂先后多次对生产工艺进行了改革,曾应用瓶培养、液体培养固体吸附、通风制曲法培养、木匣培养、竹匾培养、布袋培养、大床培养等方法。我们感到布袋培养和大床培养法是当前生产菌种粉较理想的方法,它具有产量高、质量好,节约燃料和劳力,损耗少,培养物烘干时间短,降低成本和节约水电等优点。这里仅将布袋培养法简介如下:
With the “5460” application area of bacterial fertilizer continues to expand, the production and supply of bacterial powder far can not keep up with the current needs of agricultural development. In order to do a good job supporting agriculture, various localities have created a variety of methods suitable for producing local strains of powdered bacteria and have received good results. Over the past few years, our factory has carried out several reforms on the production process. It has applied such methods as bottle culture, liquid culture solid adsorption, aeration song making method, wood box culture, bamboo plaque culture, bag culture and big bed culture. We feel that the bag culture and the bed culture method are the ideal methods for producing the strain powder currently. The method has the advantages of high yield, good quality, fuel saving and labor saving, less loss, short drying time of the culture, cost reduction and hydropower saving . Here only the bag culture method is as follows:
