针对宁夏中部干旱带一年两熟又嫌光、热不足的气候特点，进行了小麦复种大豆试验研究，结果表明：相对小麦单种，复种使太阳辐射利用率提高了25.73%，日光利用率提高了25.97%，水资源利用率提高37.9%，光能利用率提高7%，能量产投比提高25.8%，土地利用率提高26.1%，平均小麦单产5700 kg/hm2，大豆单产1200 kg/hm2，经济产投比达3.35﹕1，表现出良好的生态、经济、社会效益。

Aiming at the climatic characteristics of two crops a year but the light and heat being insufficient in the Middle Arid Zone of Ningxia, an experimental study of wheat multiple-cropping soybean was conducted. The results showed that compared with the single cropping of wheat, the multiple-cropping could increase the utilization rate of solar radiation by 25.73%, the utilization rate of sun light by 25.97%, the water resource utilization rate by 37.9%, the light energy utiliza-tion rate by 7%, the energy output-input ratio by 26.1%, the land utilization rate by 26.1%. The average yield of wheat was 5 700 kg/hm2 and the average yield of soybean was 1 200 kg/hm2. The economic output-input ratio reached 3.35︰1. It showed good ecological, economic and social benefits.
