我国玉米茎腐病研究进展

玉米茎腐病是一种世界性土传真菌病害，该病害在我国玉米产区均有发生。近年来，受耕作制度（如保护性耕作、秸秆还田等）的改变和气候变化的影响，生产中使用的高抗茎腐病的玉米品种不多等因素，致使田间病原菌数量增加，我国玉米茎腐病有逐渐加重的趋势。针对玉米茎腐病危害逐年加重的现状，本文系统综述了玉米茎腐病致病菌、发病症状表现、病情分级标准、病害侵染规律、抗性鉴定评价方法等方面的研究进展情况，并提出了玉米茎腐病的防治策略。

Research Process of Maize Stem Rot in China

Maize stalk rot is a kind of worldwide soil-borne fungal disease and occurred in the maize production area of China. In recent years, the disease was ingravescent in China due to the shift of farmingsystem (e.g., protective farming and straw returning) and weather conditions, and maize varieties with high resistance to stalk rot can use less was contributed to increasing of field pathogen. The current advances in the predominant pathogens, expressive of symptoms, classification standard, infection regulation, evaluation method of resistance identification of maize stalk rot are reviewed in details in this paper, and the control strategies of this disease are put forward, which will provide an important basis for maize resistance breeding and disease control.
