| 摘 要： | 分析比较了马铃薯4 种不同种植模式的经济效益,并对4 种模式作了综合评价。结果表明,套种可节约投入费用,具有良好的经济效益。套种模式对马铃薯单位产品投入产出效率影响不大;但可明显提高玉米的单位产品投入产出效率。从投入产出看,马铃薯投入产出效率以四套四种植模式最高,玉米投入产出效率以二套二最高。不同种植模式总体评价结果为二套二模式最佳,四套四次之。

| Abstract: | Economic benefit of different intercrop patterns of potato and maize were compared and analyzed. The result showed that potato intercropped by maize may decrease cost of the crops. Intercrop patterns have no obvious impact on input and output efficiency of unit product of potato, whereas it’s evidently enhance that of maize, and the most economical intercrop pattern was two rows of potato intercropped by two rows of maize, followed successively by four rows of potato intercropped by four rows of maize. |
