Abstract:
In order to explore the most suitable intercropping mode of summer maize/soybean in northwest Shandong, Yudan 9953 and Qihuang 34 were selected as materials for field experiment monoculture maize and monoculture soybean were treated as controls,six intercropping patterns such as the ratios of 2∶4, 2∶6, 2∶8, 3∶4, 3∶6 and 3∶8 for maize intercropping soybean were applied to study their effects on biological characters, yield and comprehensive economic benefit of summer maize and soybean.The results showed that the length of bald tip, the number of panicle rows, the number of grain rows and the weight of grain per panicle were significantly better than that of single maize under intercropping, which had positive intercropping effect. The plant height, pod height, branching, node number, effective pod number and seed number per plant of soybean were weaker than single soybean, which had negative intercropping effect.The land equivalent ratio were 1.32, 1.28, 1.21, 1.18, 1.14 and 1.11 in the 2∶4,3∶4,3∶6,2∶6,3∶8 and 2∶8 intercropping patterns respectively, and the yield-increasing benefit were obvious, especially in the 2∶4 intercropping pattern, the yield-increasing value was 4 879.28 yuan?ha-1 compared with the monoculture maize. Considering the economic benefit and small mechanical operation of different intercropping modes, the 2∶4 intercropping mode is more suitable for spreading and application in the northwest of Shandong.
