过去采用三级扩大法土法生产细菌农药,由于生产工艺较复杂,产品质量往往不稳定,成本较高,因而影响了细菌农药土法生产的普及与推广。去年,我们利用自己生产的优等三级原料(工业粉剂也可) 作菌种,直接采用一步扩大法生产细菌农药。一步扩大法生产方法简易,生产量大,产品质量稳定,成本低,每斤土法 In the past, the three-stage expansion of law and indigenous production of bactericidal pesticides has had an impact on the popularization and promotion of bacterial pesticide indigenous production due to complicated manufacturing processes, unstable product quality and high costs. Last year, we used our own excellent third-grade raw materials (industrial powder can also be) as bacteria species, directly using one-step expansion of the production of bacterial pesticides. One-step expansion method Production method is simple, large-volume production, product quality and low cost, per kg method
