杂交中稻再生利用是一项投资少、花工少、产量高、效益好的栽培制度。2001年我县再生稻栽培面积为333.3公顷，其中“双改再”面积为153.3公顷。经测产验收，头季稻单产为450千克/667平方米，再生稻单产250千克/667平方米。实践证明，要确保再生稻高产稳产，就必须搞好病、虫害?
Hybrid medium rice recycling is a less investment, less flower, high yield and good efficiency of the cultivation system. In 2001, the cultivated area of ratoon rice in our county was 333.3 hectares, of which 153.3 hectares were “double retoolized.” After testing output, the first crop yields of 450 kg / 667 square meters, ratoon yield of 250 kg / 667 square meters. Practice has proved that to ensure that high yield and stability of ratoon rice, we must improve disease and pests?
