超级稻与目前广泛种植的半矮秆水稻相比,其株型增高、稻秆增粗、穗型增大、库容增大,体内营养物质丰富,较大幅度地提高了水稻单产。但其株型结构及营养成分的变化也诱发了稻田病虫种群数量的改变,如二化螟、稻飞虱、纹枯病、稻曲病发生数量大,危害严重,特别是稻曲病已由过去水 Compared with the currently widely planted semi-dwarf rice, the super rice has an increased plant type, a thicker rice stem, an increased panicle size, an increased storage capacity, and rich in nutrients in the body, which greatly improves the yield of rice. However, its plant type structure and changes in nutrient composition also induced changes in population of rice plant diseases and insect pests, such as Chilo suppressalis, planthoppers, sheath blight, the incidence of large-scale false smut, serious harm, especially the false smut By the past water
