水稻稻曲病过去一直因发病较轻,对产量损失不大而被人们忽视。近年此病有逐年加重趋势。尤其是山区稻曲病发病更为严重。品种中以桂朝二号发病最重,穗发病率高达43.6%,粒发病率高达1.42%。其次是“汕优6号”、“丽晚1号”,穗发病率在23.9%,粒发病率在0.48%。稻曲病发生对产量虽然损失不大,但严重污染了稻谷,降低米质。丽水地区农科所、农业
Rice false smut in the past due to less incidence of light, yield loss is neglected. In recent years, the disease has increased year by year trend. In particular, the incidence of smut in mountainous areas is more serious. Among the cultivars, Guizhao No. 2 had the heaviest incidence, the ear incidence was as high as 43.6% and the incidence of grain was as high as 1.42%. Followed by “Shanyou 6”, “Li night 1”, the incidence of spike in 23.9%, grain incidence in 0.48%. The incidence of false smut on the yield although the loss is not serious, but seriously polluted the rice, reduce the quality of rice. Lishui Prefecture Agricultural Institute, agriculture
