在毛主席革命路线指引下,科学种田正在广泛展开,目前全国已在1亿亩左右的土地上应用“5406”抗生菌肥,进一步验证了它所具有的防病保苗、促进生长和肥地松土的作用。 在大规模的生产和使用中,反映出“5406”菌种的衰退问题。菌种衰退主要表现在斜面色泽变白、菌苔变薄、生长缓慢、拮抗性能减弱、易遭霉菌、细菌和噬菌 Under the guidance of Chairman Mao’s revolutionary line, scientific farming is being carried out in a wide range of fields. At present, “5406” antibacterial fertilizer has been applied to about 100 million mu of land throughout the country to further verify its preventive disease-preserving and seedling-promoting and growth-promoting The role of soil. In large-scale production and use, reflects the “5406” strain decline. Degradation of bacteria is mainly manifested in the bevel color white, thin lawn, slow growth, antagonistic performance weakened, vulnerable to mold, bacteria and phage
