摘　　要：为明确不同管理条件下的复种效益,于广州市钟落潭镇梅田村基地开展了甜玉米(Zea mays L.)一年三熟不同氮肥用量、间作复种模式研究,并于成熟期测产计算经济效益。结果表明,冬种马铃薯间作甜玉米在5∶5的行比下取得最高经济效益为29 217元/hm2,早种甜玉米在N2(225 kg/hm2)处理下取得最高经济效益为16 510元/hm2,晚种甜玉米在N3(300 kg/hm2)处理下取得最高经济效益为30 477元/hm2,一年的经济效益最高可达76 204元/hm2。适宜的氮肥用量及间作模式有利于提高甜玉米经济效益,提高土地利用率。In order to clarify the benefits of multiple cropping under the different management conditions,the different nitrogen application rates and intercropping patterns three crops per year of sweet corn(Zea mays L.)were studied at the Meitian village Zhongluotan town in Guangzhou,and the economic benefits were calculated at the maturity stage.The results showed that the highest economic benefit of winter potato intercropping sweet corn was 29 217 yuan/hm^2 at 5∶5 ratio,and the highest economic benefit of early sweet corn under N2(225 kg/hm^2)was 16 510 yuan/hm^2.The highest economic benefit of late sweet corn under N3(300 kg/hm^2)treatment was 30 477 yuan/hm^2,and the economic benefit of one year was up to 76 204 yuan/hm2.Suitable nitrogen fertilizer application and intercropping mode are beneficial to improve economic efficiency and improve land utilization.
