超级稻与目前广泛种植的半矮秆水稻相比,具有株型增高、稻秆增粗、穗型增大、库容增大、体内营养物质更丰富等特点,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,局部地区稻瘟
Compared with the currently widely grown semi-dwarf rice, super rice has the characteristics of higher plant type, thicker rice stem, larger panicle size, larger storage capacity and more abundant nutrients in the body, which greatly improves the yield of rice. However, its plant type structure and nutrient composition changes also induced changes in the population of rice plant diseases and insect pests, such as Chilo suppressalis, planthoppers, sheath blight, the incidence of false smut, the number of serious harm in some areas, rice blast
