针对固原山区一年一熟光、温资源丰富有余,一年两熟又嫌光、温不足及近年土壤盐化日益严重的特点,进行麦葵套种效益及其配套技术研究。结果表明,麦葵套种经济、生态、社会效益十分显著。太阳生理辐射利用率提高了48.86％,年日照利用率提高了50.72％,有效积温利用率提高了85.2％,降水利用率提高了106.7％,光能利用率提高了9.3％,土地利用率提高了24％,经济纯收入提高了24.73％,经济投产比达1:4.34元。
In view of the characteristics of one-year-old light in Guyuan Mountain, rich in temperature and abundant resources, double ripening in one year, too light in temperature, and lack of temperature in recent years, and the increasingly serious soil salinization in recent years, research on the benefits of wheat-wheat intercropping and its supporting technologies were conducted. The results showed that the economic, ecological and social benefits of wheat-wheat intercropping were significant. The solar radiation utilization rate increased by 48.86%, annual solar radiation utilization rate increased by 50.72%, effective accumulated temperature utilization rate increased by 85.2%, precipitation utilization rate increased by 106.7%, light energy utilization rate increased by 9.3% and land utilization rate increased 24%, net economic income increased by 24.73%, the economic output ratio of 1: 4.34 yuan.
