目前我区菌肥生产中存在菌种退化、杂菌污染、产品质量不高等问题,直接影响着菌肥生产。一、菌种退化问题。菌种好比作物的种子,有了优良的菌种,就可以提高产量,保证质量,降低成本。但在菌肥生产中经常遇到菌种生长慢、菌苔薄,形成菌丝或孢子饭少,或生长时间很不一致等菌 At present, there are some problems in our zone, such as degeneration of bacteria, contamination of bacteria and poor product quality, which directly affect the production of bacterial fertilizer. First, the strain of degradation. Strain is like the seeds of crops, with excellent bacteria, you can increase production, ensure quality and reduce costs. However, bacterial growth in the production of bacteria often encounter slow growth, thin bacteria, the formation of mycelium or spores rice less, or very inconsistent growth time and other bacteria
