| 摘要: |
| 黄河古道沙土的裸地土壤含水量在正常降水补给下可达到田间持水量的水平，直到１０月时，０－１００ｃｍ土壤含水量仍为１５％。造靠天然降水的对照处理，其土壤含水量在雨水补给下也达到田间持水量水平，在１０月花生收获时０－１００ｃｍ土壤含水量为１４％，不同灌溉处理对花生产量影响不大。 |

| Abstract: |
| The moisture in the fallow sandy soil could reach field capacity under the nor- mal precipitation and moisture content was 15% in 0-100 cm depth in October. The moisture in the peanut planted sandy soil could reach field capacity under the same precipi-tation and the soil moisture was 14% in October. There was no significant difference in peanut yield under the different irrigation levels. |
