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.
