在毛主席“备战、备荒、为人民”的伟大战略方针指引下,一个独立自主,自力更生,土法上马,制造5406抗生菌肥、“九二○”生长刺激素、杀虫菌剂的群众运动,正在我省农村各地蓬勃展开。各种中、小型的菌肥厂如雨后春笋股地在全省各地迅速地建立起来。为实现我省今年农业生产新飞跃创造了极为有利的条件。由于菌肥事业的飞速发展,菌种供应的问题已成为当前新的矛盾,许多地方都迫切希望能够培育和保存优良菌种,就地解决菌种的问题。为了满足广大贫下中农、农业技术干部的需要,下面我们介绍几种比较简单的菌种分离、纯化和保存的方法,仅供农村工作的同志参考。由于我们的水平有限,编写时间又较匆 Under the principle of Chairman Mao’s great strategy of “preparing for war, preparing for war and for the people,” a mass movement of independence, self-reliance and soil warfare to create 5406 antibacterial fertilizer, “920” growth stimulating hormone and insecticide, Are vigorously expanding throughout the rural areas in our province.
