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、“水稻川、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“水稻川、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。
A new planting pattern ＂rice-onion-potato＂ with high efficiency ot three crops per year was useu to achieve the target of ＂1000 kg grain and ten thousand yuan per 667 m^2＂ and high efficient utilization of light and heat resources in Anning River Valley. Three planting patterns： ＂flee-onion-potato＂, ＂flee-wheat＂ and ＂flee-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 ＂flee-wheat＂ and 6.16 times more than that of ＂flee-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 ＂flee-onion-potato＂ would achieve the target of ＂1000 kg grain and ten thousand yuan per 667 m^2 ＂ and has a good prospect in popularization and application in Anning River Valley.
