稻曲病[Ustilaginoidea Virens(cooke)Takahashi]对水稻的危害日趋严重,对水稻产量和品质的影响越来越大。1991年笔者在昆明进行了水稻始穗期遮光处理诱发稻曲病试验,模拟寡日照天气现象对稻曲病的发生及发病程度的影响,旨在弄清水稻始穗期光照强度与稻曲病发生的关系,为防治提供科学依据。
Ustilaginoidea Virens (cooke) Takahashi is more and more harmful to rice and has a greater and greater impact on the yield and quality of rice. In 1991, the author conducted the experiment of rice false smut induced by rice heading stage in Kunming to simulate the effect of the weather of oligotile sunshine on the incidence and incidence of rice false smut in order to find out the relationship between the light intensity of rice heading stage and rice false smut The relationship between the prevention and treatment to provide a scientific basis.
