摘　　要：为了挖掘农田的潜力、避免环境污染、合理利用水肥资源,结合二次通用旋转组合设计方法,进行了精确农业中小白菜产量量化研究,建立了产量与施肥的氮、磷、钾之间的三元二次函数关系,最终经过数据处理,获取小白菜的施肥效应函数。通过实现函数的解析,确定了各因素对产量的具体影响,从而为施肥决策奠定了良好的量化基础。试验结果表明:回归方程与现实情况能够较好的拟合,且显著性较高。该研究能够为变量施肥提供支持,从而推进精确农业变量施肥的实施。To tap the potential of farmland and avoid environmental pollution,rational use of water and fertilizer resources,the second general rotation design method for the precise quantification of agricultural production in the cabbage,the establishment of the yield and fertilizer nitrogen,phosphorus and potassium between the three quadratic function,and ultimately through the data processing function for fertilization effect of Chinese cabbage.By implementing the analytic function to determine the yield of various factors on the specific impact of fertilizer so as to lay a good quantitative decision-making basis.The results showed： regression equation to better fit the reality,and significantly higher.The variable rate fertilization can provide support to promote the implementation of precision agriculture variable rate fertilization.
