| 摘 要： | 氮肥和磷钾肥追施试验表明:适量的氮磷钾肥后移不仅能提高产量,且有一定的经济效益。增产幅度和效益的顺序为:氮肥后移>磷肥后移>钾肥后移。氮肥后移适宜比例为50%左右,宜初花期一次追施或初花期、鼓粒期二次追施;30%以上的磷钾肥可后移至初花期追施。生产上应提倡氮肥后移;在基施磷钾肥不足时,还应追施磷钾肥。

| Abstract: | The study showed that proper late application of nitrogen (N),phosphorus (P) and potassium (K) fertilizer could improve yield and economic benefits.The order of yield gain and benefits was N>P>K.The proper propotion of late N application was 50% of the total,dressing once in early flowering stage or dressing twice in early flowering stage and seed filling stage separately.30% of the total P and K fertilizers could be applied in the early flowering stage.Late N application was strongly recommended,while top ... |
