摘 要 ：通过长期定位试验，研究了砂区小麦套作花生、小麦和花生接续种植两种种植方式的产量及施肥效应。结果表明小麦套作花生相对于二作物接续种植有明显的产量优势。4年平均增产分别为27.7%和14.3%，在不施化肥时，这种效应更为明显，但其与施用化肥的增产效应相比甚小。两种方式下，单施或配合施用氮磷化肥均有显著的增产效果，

Abstract:The results of a long-term sited experiment that dealt with two cropping systems and their response to fertilization show that there were evident yield advantages in wheat and peanut relay intercropping system with a four-year average wheat yield increase by 27.7%and peanut by 14. 3%compared with s
