摘要
抗生素用于植物保护具有选择性强、与环境兼容性好等优点,以抗生素代替化学农药来防治植物病虫草害,是现代绿色农业发展的必然趋势。抗生素一般由微生物在发酵过程中产生,含量很低,且发酵液中杂质很多,分离纯化极为困难,制约了抗生素在植物保护方面的应用。就抗生素的种类、在植物保护中的应用及其分离纯化方法的研究进展进行了归纳。
There are many advantages for the antibiotics which are used to protect plant, such as wonderful environmental compatibility and high selectivity, etc. Instead of chemical pesticides, antibiotics are used to control crops diseases and insects. At the same time,it is an inevitable trend for the modern green agriculture development. Antibiotics are commonly produced by microorganisms in the fermentation process. However, the antibiotics above are low in content with impurities. As a result,they are extremely difficult to be isolated and purified, which restrict their applications to plant protection. In this paper, the types of antibiotics ,their application to plant protection, and the research progress of their isolation and purification are summarized.
