摘　　要：为探索适宜油桐(Vernicia fordii Hemsl.)幼林套种的农作物,分析不同套种模式对作物主要农艺性状及经济效益的影响。结果表明,套种对红薯农艺性状(主茎蔓长除外)无明显影响,对黄豆株高、有效分枝数、有效荚数、单株产量等农艺性状有显著影响,对玉米穗粒重有显著影响;与单作相比,套种会导致黄豆产量下降29.02%、玉米产量下降14.47%。3种套种模式以油桐+玉米经济效益最好,每公顷收益8850元,其次为油桐+黄豆和油桐+红薯,每公顷收益分别为6 300元和6 150元。Aiming to explore the efficient intercropping crops of Vernicia fordii,the effects of different intercropping patterns on agronomic characteristics and economic efficiency of crops were studied. The results showed that, the agronomic characteristics （except the main stem rength） of sweet potato were not changed. The agronomic characteristics of soybean were changed that including tree height,effective branches number,effective pod and yield. The grains weights per ear on relay cropping maize were significantly changed. Compared with single culture,the yield of soybean and maize was declined by 29.02% and 14.47%,respectively. The economic efficiency of the intereropping pattern（Vernicia fordii＋maize ） was the better to soybean and sweet potato,it was 8 850 yuan/hm2, others were 6 300 yuan/hm： and 6 150 yuan/hm2.
