| 摘 要： | 2004年在沈阳军区直属农场局龙镇第一副食品生产基地开展了作物茬口对重茬和连作大豆产量及农艺性状影响的研究.试验结果表明:在苜蓿茬和玉米茬上重茬2年大豆的产量和3年连作大豆产量分别为2 359.5、2 247.0和2 052.0 kg/hm2;以苜蓿茬上重茬大豆产量为最高,分别比玉米茬上重茬大豆产量高112.5kg/hm2、增产5.0%、差异不显著,比3年连作大豆产量高307.5kg/hm2、显著增产14.99%;玉米茬上重茬大豆产量比3年连作大豆产量高195.0kg/hm2、增产9.5%、差异不显著. |

| Abstract: | The effects of different crop stubbles on grain yield and agronomic characters of soybean continuous cropping was studied in the Longzhen Farm of Farm Bureau Directly Under Shenyang Military Area in 2004. The results showed that the soybean grain yield of soybean continuous cropping for 2 years in alfalfa stubble, that for 2 years in maize stubble and that for 2 years in soybean stubble were 2 359.5, 2 247.0 and 2 052.0 kg/hm^2 , respectively. The grain yield of soybean continuous cropping for 2 years in alfalfa stubble was more than 112.5 kg/hm^2 , an insignificant increase of 5% than that of soybean continuous cropping for 2 years in maize stubble, and more than 307.5 kg/hm^2 , a significant increase of 14. 99% than that of soybean continuous cropping for 2 years in soybean stubble. The grain yields of soybean continuous cropping for 2 years in maize stubble was more than 195.0 kg/hm^2 , an insignificant increase of 9.5 % than that of soybean continuous cropping for 2 years in soybean stubble. |
| Keywords: | yields soybean continuous cropping alfalfa stubble maize stubble |
