【目的】研究春玉米后期套种夏大豆不同种植模式对大豆产量的影响,为春玉米合理套种夏大豆提供科学依据。【方法】以广西夏大豆主推品种桂夏1号和玉米品种正大619为供试材料,于2011年在广西3个有代表性的夏大豆产区进行春玉米套种夏大豆不同模式试验,研究适宜与春玉米后期套种夏大豆的最佳种植模式。【结果】垄上双行种植平均产量最高为2754.87kg/ha,垄沟单行种植(CK)平均产量为2466.57kg/ha,最低为垄上双行隔行种植,产量为2160.70kg/ha。【结论】春玉米后期套种夏大豆最为适宜的种植模式为春玉米后期垄上双行套种夏大豆。
【Objective】 The objective of this study was to investigate the effects of different planting patterns of intercropped summer soybean on soybean yield in the latter stage of spring maize and to provide a scientific basis for rational intercropping of summer soybean in summer maize. 【Method】 The experiment was conducted in different summer maize intercropping summer soybean in three representative summer soybean producing areas in Guangxi in Guixia 1, a main summer soybean cultivar in Guangxi, and Zhengda 619 as a test material. The study was suitable And the best planting pattern of summer soybean intercropping summer soybean. 【Result】 The average yield of two-row planting in ridge was 2754.87kg / ha. The average yield of CK in single-row ditches was 2466.57kg / ha, and the lowest was double-row interplanting in ridge with the yield of 2160.70kg / ha. 【Conclusion】 The most suitable planting mode for intercropping summer soybean in the later stage of spring maize is summer intercropping with double row intercropping summer soybean.
