沿黄灌区玉米套种针叶豌豆栽培模式研究

Study on Cultivation Pattern of Corn Intercropping Needle Leaf Pea in Irrigation Districts along Yellow River

以玉米品种沈单16号和针叶豌豆品种MZ-1为材料,在甘肃沿黄灌区进行了玉米套种针叶豌豆栽培模式研究。结果表明,玉米套种针叶豌豆具有明显的间作优势,其中2行玉米套种3行针叶豌豆模式的优势最明显,为最佳套种模式,较单种玉米增产1950.0 kg/hm2,增加纯收益2896.7元/hm2;较单种针叶豌豆增产8752.5 kg/hm2,增加纯收益10693.5元/hm2。可在甘肃沿黄灌区及同类地区推广。对生产优势度和系统稳定性的分析表明,2行玉米套种2行针叶豌豆的模式还有进一步增产的潜力,且抗击外界微小干扰的能力更强。

The corn-pea intercropping pattern was studied by using corn variety Shengdai 16 and pea variety MZ-1 in Irrigation Districts along Yellow River in Gansu. The results show that corn intercropping needles leaf pea has obvious advantages of intercropping, two row corn intercropping three row pea coniferous most obvious advantages of models. The total yield and benefit increased by 1 950.0 kg/hm^2 and 2 896.7 Yuan/hm^2 compared to corn single planting, and the total yield and the benefit increased by 8 752.5 kg/hm^2 and 10 693.5 Yuan/hm^2 compared to needle leaf pea single planting. This intercropping pattern can be demonstrated in Irrigation Districts along Yellow River and the similar Districts. However, the advantages of production and system stability analysis showed that the model of two corn rows intercropping two needles pea rows the potential for further field increased is substantial, and aniti-interference ability of external minimal more stronger.
