稻曲病是一种发生历史悠久,分布广泛的真菌病害。因常在风调雨顺之年发生和流行,所以过去有人称其为“丰年病”,而忽视了它的危害。近年来随着农村经济政策的贯彻落实,广大农民的生产积极性空前高涨,耕作和施肥水平大大提高,一些高产晚熟但不抗病的品种很快推广,使稻曲病的发生面积和严重程度逐年上升。为了弄清此病的发生和危害,笔者于1982年和1983年在黔西县城关区进行了一些初步的调查研究。
False false smut is a long history, widespread fungal diseases. Because of the frequent occurrence and prevalence of good weather in the past years, some people used to call it “harvest disease” in the past, while neglecting its harm. In recent years, with the implementation of the rural economic policies, the enthusiasm of the broad masses of peasants has risen to unprecedented levels and the level of cultivation and fertilization has been greatly improved. Some cultivars that are late-maturing but not resistant to diseases are rapidly popularized, rise. In order to clarify the occurrence and harm of the disease, the author conducted some preliminary investigations and studies in Chengguan District of Qianxi County in 1982 and 1983.
