解决农药对环境的污染一直是人们所关注的问题。近年来,科研人员探讨了一些新的途径来防除杂草。目前某些研究虽然还处于初始阶段,但已显示出在无害除草中的潜在优势。利用土壤微生物除草剂是目前的热门课题。人们发现,土壤中某些微生物具有产生除草剂类化合物的作用。研究人员从几十种土壤样品中分离出几百种微生物,其中10—20％的微生物能强烈阻止杂草幼苗的生长。研究中发现,一种特殊的分离菌的提取物施
To solve the pesticide pollution to the environment has always been a concern. In recent years, researchers have explored new ways to control weeds. Although some studies are still in their infancy, the potential benefits of harmless weed control have been demonstrated. The use of soil microbial herbicide is currently a hot topic. It is found that some microorganisms in the soil have herbicidal compounds. Researchers have isolated hundreds of microbes from dozens of soil samples, and 10-20% of them strongly prevent weed seedlings from growing. The study found that a special isolation of bacteria extract facilities
