水稻稻曲病的研究与探讨

Research and Exploration on Rice False Smut

水稻稻曲病(rice false smut)已由过去次生性病害逐渐上升成为水稻生产上的重要病害之一。文章从稻曲病发现与命名简单历史、国内外发生分布与危害的现状、病原菌形态特征、稻曲病典型症状、关于稻曲病的毒性问题、稻曲病发病规律(即初次侵染与再次侵染源、稻曲病菌生物学特性、稻曲病侵染与危害、稻曲病流行规律)和药剂防治试验示范等6个方面进行了研究,对综合治理稻曲病的措施提供了可参考的途径。

Rice false smut （ hereinafter referred to as RFS） has turned into a severe kind of fungal disease from secondary disease in recent years. The discovery and nomenclature, the occurrence, distribution and damage status,the pathogenic morphological characteristics,the typical symptom,the toxicity,the occurrence regularity of RFS and the chemical control experimental demonstration are discussed in this paper. The author focuses on the occurrence regularity of RFS by analyzing the first and second infection sources,the biological characteris-tics of RFS pathogen,the infection and damage of RFS and the epidemic regularity of RFS. The author ends the article by proposing possible approaches to the comprehensive treatments of RFS.
