摘要: 油菜栽培管理模拟优化决策系统是中国农业科学院油料作物研究所和江苏省农业科学院资源与环境中心共同研制开发的。2004/05年我们在长江流域油菜主产区设置了四川绵阳、湖北武穴、安徽芜湖等3个定点的系统试验示范。在每个试验示范点,输入该试验点的常年气相资料和土壤肥力数据,通过系统操作、数据参数调整,系统自动生成具有针对性的油菜栽培管理方案,该方案含播种量、优化的播种期、栽培密度、LA分枝数、单位面积结角数以及每角粒数、干物质积累量的动态等;并提供根据合理的目标产量确定最佳施肥方案、群体质量控制方案等。最后生成可打印的表格形式,打印后作为明白纸发放到农户手中。试验示范结果显示系统给出的上述模拟优化值与...
