摘要：

应用 “3414”田间肥料试验设计方法，可配置3类7种肥料效应函数。通过对试验结果所拟合的肥料效应函数进行显著性检验，达到显著以上水平，每一试验点（土壤类型）有2类4个。各肥料效应函数求得的施肥量虽有所差异，但数据都是可靠的，因而采用他们的平均值，期待减少误差，提高精确度。由此得到 5种供试土壤能获得最高马铃薯产量为20780.6～41818.66kg/hm2，平均31264.05kg/hm2；需要施用肥料：N173.09～243.57kg/hm2，平均204.24kg/hm2；P2O556.25～82.60 kg/hm2，平均68.01 kg/hm2；K2O182.63 ～324.76kg/hm2 ，平均253.62 kg/hm2。N：P2O5：K2O＝1：0.26～0.44：0.93～1.44。获得最高马铃薯施肥效益为32014.14～66861.65元/hm2，平均49217.50元/hm2；需要施用肥料：N165.19～292.78kg/hm2，平均219.09kg/hm2；P2O55.45～82.50 kg/hm2，平均56.77 kg/hm2；K2O178.66 ～418.25kg/hm2 ，平均287.08 kg/hm2。N：P2O5：K2O＝1：0.02～0.50：1.08～1.71。

Abstract:

Applications “3414” the field fertilizer test design method, may dispose 3kind of 7 fertilizer effect function .Through the fertilizer effect function whict fits to the test result carries on the significance examination, achieved the remarkable abovelevel,each test poit(soil type) has 2kinds of 4,Obtains although the quantity fertilizer has a difference, but the data all is reliable, thus uses their mean value, Anticipated the reduced error, enhances the precision. Frorm this obtains 5kinds for to try the soil to be able to obtain the highest potato output is 20780.60~41818.66kg/hm2, average 31264.05kg/hm2;Needs to apply fertilizer:N173.09~243.57kg/hm2,average 204.24kg/hm2;P2O556.25~82.60kg/hm2,average68.01kg/hm2;K2O182.63~324.76kg/hm2,average 253.62kg/hm2. N:P2O5:K2O=1:0.26~0.44:0.93~1.44.Obtains the highest potato to apply fertilizer the benefit is 32014.14~66861.65yuan/hm2,average49217.50yuan/hm2;Needstoapply fertilizer:N165.19~292.78kg/hm2,average 219.09kg/hm2;P2O55.45~82.50kg/hm2,average56.77kg/hm2,K2O178.66~418.25kg/hm2,average287.08kg/hm2. N:P2O5:K2O=1:0.02~0.50:1.08~1.71.
