1956年初,在北京兴建了一座具有相当規模的細菌肥料厂,这个厂是专門生产細菌肥料的,两年来,这个厂在供应农業生产所需的肥料方面,起了很大的作用。在土壤中和植物共同生活的微生物很多,如根瘤菌、固氮菌、磷細菌、硅酸盐細菌等。这些細菌,分別对一定作物有促进生长和供給养分的作用。我們制造细菌肥料,首先应該把土壤中的细菌提取出来,选择出优良的菌种,这項工作就叫做“分
In early 1956, a fairly large-scale bacterial fertilizer factory was built in Beijing. This factory specializes in the production of bacterial fertilizers. In the past two years, this plant has played a significant role in supplying the fertilizer needed for agricultural production. There are many microorganisms that live together in the soil and plants, such as rhizobia, nitrogen-fixing bacteria, phosphorus bacteria, and silicate bacteria. These bacteria have the effect of promoting growth and supplying nutrients to certain crops, respectively. When we manufacture bacterial fertilizers, we should first extract the bacteria from the soil and choose the best bacteria. This work is called
