我国植物病害生物防治综述

摘要

Biological control of plant diseases is an effective technique and methods with the beneficial microorganisms or microbial metabolites against crop disease.This article describes the differences of Chinese biological control and chemical control,positive significance and the types of biological factors.Combined with the theory of biological control and application status,we reviewed the biological effectiveness of prevention and disease prevention mechanisms specifically on the application and exploration,the major work of biological control of plant diseases is to integrate the major disciplines of modern science and technology to further clarify clearly molecular mechanisms of different biocontrol factors controlling plant diseases.%植物病害生物防治是利用有益微生物和微生物代谢产物对农作物病害进行有效防治的技术与方法,该文介绍了我国生防与化防的不同和积极意义,概况归类说明了生物防治因子的种类;结合有害生物防治原理和应用现状,评述了生物防治的有效防治,其生防机制在防病机制上的应用和探索。
