| 摘 要： | 目的]研究大豆、玉米不同种植方式对氮积累量及产量的影响。方法]采用田间小区试验,设置3个氮素水平以及3种种植方式。结果]在玉米/大豆混作系统中的玉米表现出竞争优势,产量比单作玉米高0.36%～3.74%,而混作中的大豆产量比单作大豆降低了26.93%～46.90%。结论]混作处理的总氮肥利用率和总产量均高于单作玉米和单作大豆,整个混作系统表现出混作优势。

| Abstract: | Objective]The research aimed to study the effects of cropping patterns on nitrogen accumulation and the yield of soybean and corn.Method]A field experiment of three nitrogen levels and three cropping patterns was carried out.Result]In the mixed cropping system,corn showed a competitive advantage,and the yield was higher than that of monocropping by 0.36%-3.74%.However the yield of soybean in the mixed cropping system was lower than that of monocropping by 26.93%-46.90%.Conclusion]Total nitrogen use efficiency of mixed cropping and total yields were higher than those of monocultured corn and monocultured soybean,and the mixed cropping system showed an advantage of mixed cropping. |
