2018年杭州市余杭区首次引进再生稻栽培技术，示范方头季稻平均产量10 201.5 kg/hm2，再生季平均产量5 401.2 kg/hm2，两季稻产量达到15 602.7 kg/hm2，取得了较好的成效。示范表明，再生稻种植产量、效益明显高于其他种植模式，种一次收两季，省工省力，是提高稻田复种指数、增加粮食总产和种粮效益的有效途径之一。

In 2018, Yuhang District introduced the cultivation technology of ratoon rice for the first time. The average yield of demonstration main crop rice was 10 201.5 kg/hm2, the average yield in the regeneration season was 5 401.2 kg/hm2, and the yield of rice in two seasons reached 15 602.7 kg/hm2, which achieved good results. The demonstration showed that the yield and benefit of ratoon rice were significantly higher than other planting modes. It was one of the effective ways to increase the multi-crop index of rice fields, increase the total output of grain and the benefits of growing grain.
