杂交水稻茎杆粗壮,根系发达,穗大粒多,适应性广,具有较好的丰产性状.大力推广和种植杂交水稻,对夺取我省粮食增产有着积极的作用.由于杂交水稻叶色特别浓绿,抽穗期较长,当前高度抗病虫的杂交水稻组合还不多,比较容易遭受病虫的孳生为害.因此,加强防治病虫害,对种好杂交水稻就显得更加重要.从几年来的实践看,要特别注意加强稻瘟病、白叶枯病和稻飞虱、螟虫这二病二虫的防治工作. Hybrid rice stem stout, developed root system, spike large grain, wide adaptability, with good yield characteristics .To promote and planted hybrid rice, to seize the province to increase grain production has a positive effect.Because hybrid rice leaf color is particularly dark green , The longer the heading date, the current highly resistant to pest hybrid rice combinations are not many, more susceptible to the breeding of pests and diseases. Therefore, strengthening the prevention and control of pests and diseases, the hybrid rice is even more important. , Pay special attention to strengthening the prevention and control of rice blast, bacterial leaf blight and planthoppers, stem borer two diseases.
