| 中文摘要: |
| 于2014年在宣威市农业技术示范基地开展了玉米间作马铃薯集雨保墒抗旱栽培复合技术试验研究。试验处理包括：T1：玉米+开沟覆膜‖马铃薯；T2：玉米+打塘覆膜‖马铃薯；T3：玉米+平作覆膜‖马铃薯；T4：玉米平作覆膜单作；T5：马铃薯单作。结果表明，T1和T2处理玉米土壤含水量均高于其它处理，T1、T2处理0～7.6 cm土层玉米平均土壤含水量比T4处理最多增加28.32%，0～20 cm土层最多增加28.12%；间作处理马铃薯的土壤含水量均高于马铃薯单作，T1、T2处理马铃薯平均土壤含水量在0～7.6 cm和0～20 cm两个土层分别比T5处理最多增加23.52%和12.78%；T1、T2处理玉米产量、复合产量和土地当量比（LER）均高于T3处理，其中，T2处理的土地当量比最大（LER=1.20），比T3处理增加10.52%，产量效益明显。 |
| 英文摘要: |
| The field experiment was conducted to investigate the effect of maize‖potato intercropping on drought resistance in the Agricultural Technology Demonstration Base of Xuanwei city in 2014. The treatments include: T1, maize + ditching + polythene mulch intercropping with potato; T2, maize + pitting + polythene mulch intercropping with potato; T3, maize + polythene mulch intercropping with potato; T4, maize monoculture with polythene; T5, potato monoculture. The results showed that mean soil moisture of treatment T1 and T2 in maize field were higher than that of treatment T4, as increased by 28.32% in 0～7.6 cm soil layer and 28.12% in 0～20 cm soil layer respectively. Soil moisture of treatment T1 and T2 in potato field were increased by 23.52% in 0～7.6 cm soil layer and 12.78% in 0～20 cm soil layer compared with treatment T5. Treatment T1 and T2 significantly increased the yield of maize and land equivalent ratio(LER) than treatment T3, the LER of T2(LER=1.20) was 10.52% higher than T3. |
