【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。更多还原

【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.更多还原
