摘　　要：研究了间作配置和间作中苏丹草（Sorghumsudanense）不同播种量对苏丹草与野生大豆（Glycine so-ja）间作性能的影响。结果表明,不同间作配置对苏丹草、野生大豆和间作混合草的干物质产量影响显著,表现为：单行间作〉2行间作〉4行间作。不同间作配置下,间作混合草干物质产量土地当量比（LER）为1.02-1.19,粗蛋白（CP）产量的LER为1.05-1.32,表明间作有生产优势;苏丹草干物质产量的LER为0.54-0.66,粗蛋白产量的LER为0.55-0.82,野生大豆干物质产量和粗蛋白产量的LER分别为0.48-0.53和0.36-0.49,这表明间作中苏丹草有生长优势,竞争力比野生大豆强。间作种植,苏丹草播种量增加,提高了苏丹草、混合草的干物质产量和干物质产量的LER,但降低了野生大豆干物质产量和干物质产量的LER;同时,提高了苏丹草、野生大豆和混合草CP含量以及CP产量的LER。The objectives of this study were to determine effects of intercropping configuration and sowing rate of sudangrass（Sorghum sudanense） on sudangrass-wild soybean（Glysine soja） intercropping performance.The results were as follows： The effects of intercropping configuration on dry matter yields of sudangrass,wild soybean and intercrop components were significant,and showed as single row intercropping〉double rows intercopping〉four rows intercopping.The land equivalent ratio（LER） of intercrops components ranged from 1.02 to 1.19 on a dry matter yield basis and from 1.05 to 1.32 on a protein yield basis under different intercropping configuration,indicating a production advantage of intercropping.The LER of sudangrass in intercropping ranged from 0.54 to 0.66 on a dry matter yield basis and from 0.55 to 0.82 on a protein yield basis,the LER of wild soybean in intercropping ranged from 0.48 to 0.53 on a dry matter yield basis and from 0.36 to 0.49 on a protein yield basis,indicating a growth advantage of sudangrass over wild soybean in intercropping.The dry matter yields and LER on a dry matter yield of sudangrass and intercropping combined forage yields were increased with sowing rate of sudangrass increased,but the dry matter yields and LER on a dry matter yield of wild soybean were decreased.At the same time,with increasing the sudangrass sowing rate,CP concentration and LER on a protein yield of sudangrass,wild soybean and combined forage were all increased.
