| 摘 要： | 采用“3414”回归最优设计原理设置小麦肥效试验，根据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、钾最佳施肥量分别为N184．5kg／hm^2、P2O5 78．0kg／hm^2、K2O 58．5kg／hm^2，最佳产量7021．5kg／hm^2。综合分析结合当地农业生产实际，潮土类两合土的氮、磷、钾建议施肥量分别为180～225kg／hm^2、75～90kg／hm^2和60～75kg／hm^2。

| Abstract: | By the'3414'manure trial,the optimum theoretical fertilizations of N,P and K were 184.5 kg/hm2,78.0 kg/hm2 and 58.5 kg/hm2,respectively.According to the comprehensive analysis with the production practice,the suggestive application of N,P and K in aquic-fluvial soil were 180-225 kg/hm2,75-90 kg/hm2and 60-75 kg/hm2. |
