为了提高土地产出率，增加农民收入，探索粮食作物和经济作物双丰收的高效途经，通过3年的研究，创建了“头季稻-再生稻-马铃薯”高效种植模式。结果表明，该模式增产又增收，总产量为63.25 t/hm2，其中头季稻产量为13.14 t/hm2，再生稻产量为2.68 t/hm2，马铃薯产量为47.43 t/hm2，总产值16.98万元/hm2，总纯收入12.03万元/hm2。并分析总结了头季稻、再生稻、马铃薯关键栽培技术。

In order to improve the land productivity, increase the income of farmers, field experiment was carried out to explore the efficient way of double bumper harvest about grain crops and economic crops. After 3 years of study, the authors created a “first cropping rice + ratoon rice + potato” high efficient planting mode. The results showed that the mode has high yield and efficiency. The total yield was 63.25 t/hm2, the yield of first cropping rice was 13.14 t/hm2, the yield of ratoon rice was 2.68 t/hm2, the yield of potato was 47.43 t/hm2, and the total output value was 169 800 yuan/hm2, the total net income was 120 300 yuan/hm2. This article summarized the key techniques of “first cropping rice + ratoon rice + potato” planting mode.
