摘要
在唐山市丰南区开展了花生田间"3414"肥效试验,通过对各小区产量进行统计分析,获得肥料效应函数方程;结合当地农业生产实际,氮、磷、钾建议推荐量分别为163.5kg/hm2、135kg/hm2、133.5kg/hm2,其最佳比例为1∶0.83∶0.82。
Carrying out"3414" fertilizer experiment in peanut field on Fengnan District of Tangshan, by statistical analysis of the cell yield obtained fertilizer response function equation; with local agricultural production practice, N,P and K recommendations were recommended amount of 163.5 kg/hm2, 135.0 kg/hm2, 133.5 kg/hm2, the best ratio of 1:0.83:0.82.
