| 摘 要： | 借用作物产量预报的研究方法,以现代数理统计方法为手段,以北京地区30余年小麦产量、气象数据时间序列为材料,通过定性划分作物产量年型,给出了基于年景变化施肥决策的一般方案。这对传统的肥料一作物产量施肥模型来说,是一种研究领域上的拓宽。 |

| Abstract: | To consider fertilization strategy for different crop yield year type.Theories and methods crop yield prediction in agricultural meteorology research were used.Using winter wheat yield and meteo- rological historic data of Beijing area,we established a successful Bayes discrimination analysis model to predict crop yield year type.The general fertilization strategy for different crop yield year types was given. The traditionalsoil-fertilizer-cropmodel was widened because climate change was taken into account... |
