为研究适合黑龙江八五三农场地区玉米最佳施肥量,采用"3414"试验方案进行了肥效试验,拟合了肥料效应一元二次方程和三元二次方程。通过一元二次方程拟合分析得出,在该土壤条件下的最大的施氮量、施磷量和施钾量分别为147.96、85.635和44.205kg·hm-2,最佳的施氮量、施磷量和施钾量分别为76.245、52.98和32.4kg·hm-2。氮、磷、钾三者必须配合施用才能达到高产,任何一种营养元素受到胁迫都不利于高产。通过三元二次方程得出,在该土壤条件下,氮、磷、钾最高施肥量为N-P2O5-K2O=131.7-85.3-36.1(kg·hm-2),对应的最高产量为9 522.81kg·hm-2。最佳施肥量N-P2O5-K2O=82.7-54.1-33.6(kg·hm-2),其对应的产量为9 288.54kg·hm-2。
為研究適閤黑龍江八五三農場地區玉米最佳施肥量,採用"3414"試驗方案進行瞭肥效試驗,擬閤瞭肥料效應一元二次方程和三元二次方程。通過一元二次方程擬閤分析得齣,在該土壤條件下的最大的施氮量、施燐量和施鉀量分彆為147.96、85.635和44.205kg·hm-2,最佳的施氮量、施燐量和施鉀量分彆為76.245、52.98和32.4kg·hm-2。氮、燐、鉀三者必鬚配閤施用纔能達到高產,任何一種營養元素受到脅迫都不利于高產。通過三元二次方程得齣,在該土壤條件下,氮、燐、鉀最高施肥量為N-P2O5-K2O=131.7-85.3-36.1(kg·hm-2),對應的最高產量為9 522.81kg·hm-2。最佳施肥量N-P2O5-K2O=82.7-54.1-33.6(kg·hm-2),其對應的產量為9 288.54kg·hm-2。

In order to research the optimal fertilizer application in area of 853 Farm in Heilongjiang province,the field experiment of fertilizer effect was conducted using '3414' method.Quadratic equation of one variable and quadratic equation of three variables were studied.According to the quadratic equation of one variable,the most fertilization N-P2O5-K2O was 147.96,85.635 and 44.205 kg hm-2,and the most economical fertilization N-P2O5-K2O was76.245,52.98 and 32.4 kg hm-2.The three fertilizer must go together with each other,any one on the stress was not good for high yield.According to quadratic equation of three variables,the highest yield of 9 522.81 kg·hm-2would be reached when N-P2O5-K2O=131.7-85.3-36.1 kg·hm-2,The optimal fertilizer applied was N-P2O5-K2O=82.7-54.1-33.6 kg·hm-2 and yield was 9 288.54 kg·hm-2.
