| 摘 要： | 利用3414肥料效应试验,对河北省藁城市冬小麦高产栽培的氮、磷和钾肥料效应进行了研究。结果表明,高产条件下冬小麦的肥料效应差异很大,其中氮肥在高产田块上增产较明显,而在中低产条件下增产不明显;磷肥则在中低产条件下增产较明显,高产条件下增产不明显;而钾肥的增产效应表现均不明显。最佳推荐施肥量为N 151.6 kg/hm^2、P2O5126 kg/hm^2和K2O 52.1 kg/hm^2。

| Abstract: | Based on ten "3414"winter wheat fertilizer effect experiments,the effects of N,P and K fertilizer on winter wheat were studied.The results showed the yield effects of N,P and K were different.The N fertilizer significantly increased wheat yield in high level yield fields,but not in middle and low level yield fields.The P fertilizer significantly increased wheat yield in middle and low level yield fields,but not in high level yield fields.However,the K fertilizer did not significantly increase wheat yield in any level yield field.The results indicated the optimum recommend fertilization was N 151.6 kg/hm2,P2O5 126 kg/hm2 and K2O 52.1 kg/hm2,respectively. |
