为了减少撒施于农田中的化学制品,苏联科学家目前正在为农作物研制细菌肥料和疫苗。弗拉基米尔伊格纳托夫生物化学和植物生理研究所的科研人员,已在小麦根系中发现了许多微生物,这些微生物与植物形成共生关系,并能刺激作物生长。这些科研人员用一种或更多的这类细菌来处理种子,该方法现已应用于某些豆科作物上。他们先用称为“根瘤菌肥”的固氮菌处理种子,然后再与泥炭等载体混合,已在增加作物产量上获

In order to reduce the chemical sprinkled on farmland, Soviet scientists are currently working on the development of bacterial fertilizers and vaccines for crops. Researchers at the Institute of Biochemistry and Phytophysiology at the Vladimir Ignatius Institute for Biochemistry and Plant Physiology have found many microbes in the wheat root system that form symbiotic relationships with plants and stimulate crop growth. These researchers treat seeds with one or more of these bacteria, and the method is now applied to some leguminous crops. They first treated the seeds with nitrogen-fixing bacteria called “rhizobium fertilizer” and then mixed them with peat and other carriers, which have been increased in crop yields
