摘  要:
[目的]建立安徽省繁昌县小麦施肥指标体系。[方法]通过"3414"回归最优设计原理设置的杂交油菜肥效试验结果,获得肥料效应函数方程,由此数学模型推算出氮、磷、钾最佳施肥量理论值。[结果]试验结果表明,N 15.64 kg/667m~2、P2O57.85 kg/667m~2、K_2O 8.54kg/667m~2,最佳产量为411.2 kg/667m~2。[结论]综合分析不同推荐施肥方法的推荐施肥量,结合当地农业生产实际,将目标产量确定在351 kg/667m~2产量水平左右,氮、磷、钾建议推荐量分别为N 13.36 kg/667m~2、P_2O_55.58 kg/667m2、K_2O 8.1 kg/667m2。

摘  要:
[Objective] The aim was to set up Fanchang County indicator system for fertilization of wheat in Anhui Province. [Method] Through the results of hybrid rape fertilizer test which set by "3414" regression optimal design principle,the equation of fertilizer effect function was obtained,and the best nitrogen, phosphorus, potassium fertilizer theoretical value was calculated by the mathematical model. [Result] The results showed that, the yield was the best( 411.2 kg/667m~2), with N 5.64 kg/667m~2,P_2O_57.85kg/667m~2, K_2O 8.54 kg/667m~2. [Conclusion] Based on the actual agricultural production, the target yield was determined to be about 351 kg/667m~2, and the recommended amount of N, P and K was recommended as N 13.36 kg/667m~2, P_2O_55.58 kg/667m~2, K_2O 8.1 kg/667m~2, respectively.
