稻曲病是水稻后期发生的一种真菌性病害。近些年来随着杂交稻的普遍种植,晚稻发生普遍而严重。总的趋势是杂交稻重于常规稻,粳稻重于籼稻,晚稻重于中稻,中稻重于早稻。晚稻受稻曲病危害后,不仅千粒重,产量下降(一般减产10%~20%,严重时可达30%以上),秕谷、碎米增加,出米率和品质降低;而且病粒作为饲料,肉猪食后,生长、增重速度下降,母猪食后,死胎、畸形胎增加,仔猪成活率降低。 False smut is a fungal disease that occurs late in rice. In recent years, with the widespread planting of hybrid rice, the occurrence of late rice is widespread and serious. The general trend is that hybrid rice is heavier than conventional rice, japonica rice is heavier than indica rice, late rice is heavier than middle rice, middle rice is heavier than early rice. Late rice affected by rice germ disease, not only the weight of 1000 grain, yield decreased (generally reduced by 10% to 20%, severe up to 30% or more), 秕 Valley, broken rice increased rice yield and quality to reduce; and pellets as feed , Pigs after eating, growth, weight loss rate, sows after eating, stillbirth, deformed fetus increased, lower survival rate of piglets.
