【摘要】 利用"小麦—玉米连作智能决策系统",对河北吴桥县小麦—玉米连作生产进行了模拟。结果表明:模型对生育期的模拟值与实际值有很好的一致性;经分析,作物水氮环境与实际生产条件相符合;地上部干物质与实际干物质的增长趋势一致;模型对小麦的产量模拟值稍高于实测值,玉米的模块值低于实测值。更多还原

【Abstract】 WheatMaize continuous Cropping Intelligent Decision System" was used to simulate the continuous production of Wuqiao County in Hebei Province.Results showed the simulated had a good corelation coefficient with the actual experiment data,such as growing development,soil water and nitrogen environment and the increasing trend of overground dry matter.The simulated yield of wheat was higher than the actual yield,yet the simulated yield of maize was lower than the actual yield.更多还原
