摘要
对唐山市4个县(市)2006/2007年冬小麦"3414"肥料效应试验结果进行分析,研究了冬小麦氮、磷、钾肥的肥料效应。结果表明:唐山市4县(市)冬小麦的基础产量(不施肥处理)差异较大;基础产量较高的县(市),产量水平和最高产量也较高。利用数学模型对肥料效应进行分析,认为唐山市冬小麦的最佳推荐施肥量为氮肥(N)130 kg/hm2、磷肥(P2O5)100 kg/hm2和钾肥(K2O)80 kg/hm2。
The fertilizer effect of ‘3414' experiment on winter wheat in Tangshan from 2006 to 2007 was analyzed. The results showed that there were great differences in the basic yield of wheat in four counties of Tangshan. The yield level and the highest yield were higher in the counties with higher basic yield. The recommended optimum fertilization rate was N 130 kg/hm^2, P2O5 100 kg/hm^2 and K2O 80 kg/hm^2.
