在靖远县开展的不同前茬复种蔬菜效益对比试验结果表明，与单种小麦相比，单种针叶豌豆的产量略低，但产值较高、成本投入较低，是比较理想的复种前茬。针叶豌豆茬的蔬菜产量普遍高于小麦茬，其中大白菜增产15.33%，青萝卜增产23.55%，甘蓝增产15.21%。豌豆茬较小麦茬复种大白菜增收54.02%，复种青萝卜增收36.25%，复种甘蓝增收55.19%。豌豆茬复种蔬菜比小麦茬既增产又增收，是最佳模式。

The benefits comparison test of multiple cropping vegetable after different crops harvest was studied in Jingyuan county . The results showed that Single crop pea yield slightly lower than the single crop wheat， but high output， low cost investment， because the legume has nitrogen fixation， is an ideal cropping stubble . The vegetable yield is coniferous pea stubble higher than that of wheat stubble， the yields of Chinese cabbage increased was 15.33%， green radish increased was 23.55%， cabbage increased was 15.21%. The mixed income of different pea stubbles higher than that of wheat stubble， multiple cropping cabbage income 54.02%； multiple cropping green radish increase 36.25%， multiple cropping cabbage increase 55.19% . Pea cropping vegetables than wheat stubble can increase yield and income increase， but also can ensure the quality of vegetables， is the best mode .
