| 摘 要： | 通过“3414”回归最优设计原理设置的作物肥效试验结果，获得肥料效应函数方程，由此数学模型得出理论氮、磷、钾最佳施肥量，其中N8．60-9．68kg／667m^2，P2O53．47-3．76kg／667m^2，K2O5．48-5．91kg／667m^2，最佳产量410．99-413．42kg／667m^2。根据田闽试验及土壤测试结果，结合当地农业生产实际，建议氮、磷、钾推荐量分别为N9．3kg／667m^2、P2O53．5kg／667m^2、K2O5．6kg／667m^2，或者N9．2kg／667m^2、P2O53．0kg／667m^2、K2O6．0kg／667m^2，或者N9．1kg／667m^2、P2O23．5kg／667m^2、K2O6．1kg／667m^2。

| Abstract: | Based on the results of crop fertilizer effectiveness experiment by means of regression best-design principle, a function equation was obtained, from which the best fertilization amount can he calculated by a math model. Thereinto, N： 8.60-9.68 kg/667m^2,P2O5： 3.47-3.76 kg/667m^2, K2O：5.48-5.91 kg/667m^2 ,best yield： 410.99-413.42 kg/667m^2. Based on the results of field experiment and soil test, integrating local condition of farming production, the recommended fertilization amount of N, P, K are N 9.3 kg/667m^2、P2O5 3.5 kg/667m^2、K2O5.6 kg/667m^2 or N 9.2 kg/667m^2,P2O5 3.0 kg/667m^2 ,K2O6.0 kg/667m^2, or N 9.1 kg/667m^2 ,P2O5 3.5 kg/667m^2 ,K2O6.1 kg/667m2. |
