摘要
在草甸白浆土上对春小麦进行了氮磷钾不同配方的田间小区肥料试验。结果表明:不同的肥料配方对小麦生长发育的影响不同,小麦吸收氮磷钾养分的能力不同,从而导致小麦产量的差异。本试验以N﹕P2O5﹕K2O为6﹕8﹕3的处理小麦吸收养分的能力最强,主要表现在磷促进了氮的吸收,小麦产量性状最好,产量最高达到了4761.5kg/hm2。
The field experiment of fertilizing was conducted in meadow albic soil to study the effect on spring wheat. In the experiment, the fertilizer of N, P, K were involved. The results indicated that different fertilizers prescription could effect the absorption of N, P, K of sprig wheat. The treatment N：P2O5：K2O=6：8：3 was the most effective. In this treatment the P could promote absorption of the N significantly and the maximum grain yield reach 4 700 kg/hm^2.
