| 中文摘要: |
| 探究大豆玉米带状复合种植模式对玉米产量及品质的影响，筛选出适宜带状复合种植的玉米大豆品种组合,通过田间试验，在大豆玉米带状复合种植模式（4 +2）及玉米单作模式下，设置2个玉米品种(Y1：391;Y2：德发719),3个大豆品种(D1：新振豆1号;D2：新大豆8号;D3：新大豆26号)，测定玉米农艺性状、产量及品质指标。结果表明与单作相比，带状复合种植体系玉米产量整体有所降低。在复合种植模式下，从产量及构成因素方面来看，小区玉米穗数、总穗重、折算产量分别为70.67、11.02 kg、1 045.5 kg/667 m2,且均在Y1D3处理达最大值,而穗粒数和百粒重分别为685.89、42.57 g。在Y1D2处理达最大值，从品质来看，玉米蛋白质、脂肪、粗淀粉含量分别为9.54%、4.70%、 76.95%,均在Y1D3处理下达最大值，相关性分析表明，玉米穗粒数、穗数、穗粗和总穗重均与玉米产量呈显著正相关，相关系数分别为0.89、0.89、0.74、0.94。因此，大豆玉米复合种植体系中，Y1D3处理可作为本地区大豆玉米带状复合种植模式下适宜推广的大豆玉米品种组合。 |

| The effects of soybean–maize strip intercropping on maize yield and quality are investigated to identify suitable soybean-maize variety combinations. Field experiments were conducted under a soybean-maize strip intercropping system (4 + 2) and a maize monoculture system. Two maize varieties (Y1: 391; Y2: ‘Defa 719’) and three soybean varieties (D1: ‘Xinzhen 1’; D2: ‘Xindadou 8’; D3: ‘Xindadou 26’) were used. Agronomic traits, yield, and quality parameters of maize were measured. Compared with maize monoculture, maize yield decreased overall under strip intercropping. In terms of yield and its components, the number of ears per plot, total ear weight, and calculated grain yield were highest under the Y1D3 treatment (70.67, 11.02 kg, and 1045.5 kg/667 m2, respectively), whereas the number of grains per ear and 100-grain weight were highest under the Y1D2 treatment (685.89 and 42.57 g, respectively). In terms of quality, protein, fat, and starch contents were highest under the Y1D3 treatment (9.54%, 4.70%, and 76.95%, respectively). Correlation analysis showed that grains per ear, ear number, ear length, and total ear weight were significantly positively correlated with maize yield, with correlation coefficients of 0.89, 0.89, 0.74, and 0.94, respectively. Overall, the Y1D3 treatment is a suitable soybean-maize variety combination for strip intercropping in this region. |
