摘要： 为实现凉山州贫困山区“吨粮万元”的发展目标，高效利用安宁河谷地区秋冬光温资源，本研究在安宁河谷地区设置“水稻-小葱-马铃薯”一年三熟种植新模式、“水稻-小麦”和“水稻-油菜”2种传统模式。结果表明：“水稻-小葱-马铃薯”模式较当地传统的“水稻-小麦”和“水稻-油菜”模式复种指数提高了50%，原粮产量与“水稻-油菜”模式相当，总产值和净产值比“水稻-小麦”和“水稻-油菜”模式提高了3.6~4.1倍。扣除劳动力成本后，“水稻-小葱-马铃薯”模式的纯收益较“水稻-小麦”模式提高3.19倍，较“水稻-油菜”模式提高6.16倍，且其新增纯收益率达到4.19~6.16元/元。“水稻-小葱-马铃薯”一年三熟种植新模式在凉山州安宁河谷地区实现了“吨粮万元”的发展目标，具有良好的推广应用前景。

Abstract: A new planting pattern “rice-onion-potato” with high efficiency of three crops per year was used to achieve the target of “1000 kg grain and ten thousand yuan per 667 m2” and high efficient utilization of light and heat resources in Anning River Valley. Three planting patterns: “rice-onion-potato”, “rice-wheat” and “rice-rape”, were constructed in Anning River Valley in this study. The results showed that: compared with the local traditional patterns, the cropping index was improved by 50%, grain yield was equivalent while total output value and net output value increased from 3.6 times to 4.1 times. Excluding labor cost, the pure benefit of new pattern “rice-onion-potato” was 3.19 times more than that of “rice-wheat” and 6.16 times more than that of “rice-rape”, while the increased net profit ratio was 4.19-6.16 yuan/yuan. As a high efficient grain and cash crops compound planting pattern, the new pattern “rice-onion-potato” would achieve the target of “1000 kg grain and ten thousand yuan per 667 m2” and has a good prospect in popularization and application in Anning River Valley.
