摘  要：為了確定玉米栽培氮磷鉀3元素肥料效應(yīng)參數(shù)，以及玉米肥料效應(yīng)的最佳施肥量等，通過“3414”田間試驗(yàn)，摸索玉米生產(chǎn)氮磷鉀3元素的合理施肥用量，得出在亮兵鎮(zhèn)的情況下玉米施肥應(yīng)以處理12（N1P1K2）為首選，該試驗(yàn)為農(nóng)民科學(xué)施肥提供了依據(jù)。

Abstract： In order to determine the fertilizer effect parameters of nitrogen， phosphorus and potassium for corn cultivation and the optimal amount of fertilizer for corn fertilizer effect， the "3414" field experiment was conducted to explore the reasonable amount of fertilizer for nitrogen， phosphorus and potassium for corn production. It was concluded that treatment 12 （N1P1K2） should be the first choice for corn fertilization in the case of Liangbing town. This experiment provides a basis for farmers to apply fertilizer scientifically.

Keywords： corn; soil testing and fertilization; "3414" experiment; increase production; optimum fertilizer amount

吉林玉米產(chǎn)區(qū)主要土壤類型為黑土、黑鈣土等，具有腐殖質(zhì)層厚、有機(jī)質(zhì)含量高及養(yǎng)分豐富等特點(diǎn)，對玉米生長非常有利。（剩余2186字）
