摘　　要：为探寻山区单季稻和再生稻高产气象技术,在尤溪县高山区和低山区分期播种5个杂交稻品种。结果明确,不论低山区或高山区于3月中旬早播种,将产量物质形成期调整在强光适温的季节,结实率高,比迟播田增产5%～10%。其中2个具有较强再生力的品种在低山区早播种,再生季安全开花结实,比迟播田成倍增产。结果表明早播种趋利避害利用气候资源,充分发挥了气候生态的生产潜力。In order to investigate meteorological technique for high yield of single cropping and ratoon rice in mountain area,the interval sowing experiment of five hybrid rice varieties were established in high and low mountain areas of Youxi county of Fujian province.The results showed that the early sowing in mid-March in either high or low mountain areas adjusted formation stage of yield matter in the strong light and optimum temperature season,which resulted in high seed set and the yield was increased by 5%～10% compared with the late sowing.Two of them with stronger regeneration capacity were sowed early in low mountain areas,and then flowering and seed setting were safety.Finally,the yield increased a duplication compared with the late sowing.The results indicated that the early sowing was use of climate resources while avoiding disadvantages and gave full play to the production potential of climatic ecology.
