| 为最大限度地提高水分利用率，对半干旱区全膜双垄沟播种植西葫芦进行不同生长时期的注水补灌试验。结果表明：进行注水补灌后，西葫芦667m2增产14.07%～26.24%、增收536.55～984.17元，产量随着注水补灌次数增加而增加，以初瓜期+盛瓜期+中后期注水处理的产量最高（4784.77kg），净收益以初瓜期+盛瓜期注水处理的最好（5532.58元）。 |

| Abstract: In order to maximize the water use efficiency, supplemental irrigation experiment was carried out on squash under the all-film doubile-furrow sowing in different growth periods. The results showed that after water injection and irrigation, the yield of squash was increased by 14.07%～26.24% per 667 m2, and the income was increased by 536.55～984.17 yuan. Squash yield was increased along with the increase of irrigation times, and the highest yield (4 784.77 kg) was got when water was injected during initial melon period + full melon period + late period. The best net income (5 532.58 yuan) was obtained under injecting water during initial melon period + full melon period. |
