摘要
对玉米-大豆带状复合种植和单种玉米两种种植模式下玉米各生育时期、农艺性状、产量及经济效益等因子进行比较分析,结果表明:与单种玉米相比,玉米-大豆带状复合种植条件下玉米各生育时期没有明显变化,株高、茎粗等农艺性状增加明显,产量性状的各指标都表现出良好的态势,双穗率、穗粒数和百粒重明显增加,空秆率和秃尖长降低,且差异相对明显;带状复合种植较单种玉米增产增效明显,增产24.51%,增收7359.9元/hm2,纯收入提高6162.6元/hm2,增加69.21%,产投比达到2.59,增加24.51%。
Growth period,agronomic traits,yield and economic benefit of maize-soybean strip intercropping and maize single planting were compared in this paper.The results showed that compared with maize single planting,growth period of maize-soybean strip intercropping had few changes,plant height and stem diameter increased significantly,double ear rate,grain number per spike and hundred grain weight increased also increased significantly,and empty stalk rate and bald-tip length decreased significantly.Compared with maize single planting,maize-soybean strip intercropping made the yield increase by 24.51%,income increase 7359.9 yuan/hm2,net income increase 6162.6 yuan/hm2(increase by 69.21%),and output-input ratio reach 2.59(increase by 24.51%).
