| 摘 要： | 对 30余种间作套种组合种植作物的耗水量、产量、产值及其根区土壤含水量进行了分析研究。结果表明 :1作物组合种植具有明显的节水增产增收效果 ;2作物组合种植条件下 ,处于雨季后期的作物生长 ,达到了对光、热、水资源的同步利用 ,明显的提高了雨水资源的利用率。同时分析得出了作物组合种植形式需水规律的特点。

| Abstract: | Evapotranspiration, yield, production value,and soil moisture in root zone for 30 kinds of intercropping systems under different irrigation water application were studied in this paper. The results shown that: (1) total yields and total production values of crops, regardless of calculating on unit area and unit water use, increase obviously under intercropping systems; (2) with intercropping system, solar energy, heat resource, and precipitation were all used more efficiently. In addition, the total crop water requirement for intercropping systems also were given. |

| Keywords: | evapotranspiration yield water saving intercropping water use efficiency |
