氮肥的增产效果与氮肥利用率有密切关系,一般说来,氮肥利用率高,氮肥的增产效果也大,但往往也存在氮肥利用率高,而增产不明显的例子,如小麦植株生长茂盛,而籽实产量很低.为了达到氮肥利用率高,增产效果也明显的目的,需要注意各种营养元素的均衡供给.从这一观点出发,本试验研究在磷钾元素充足供给条件下,对提高氮素利用率的影响.
Nitrogen fertilizer production efficiency is closely related with nitrogen use efficiency. Generally speaking, nitrogen fertilizer utilization rate is high, nitrogen fertilizer production yield is also large, but often there are also nitrogen fertilizer utilization rate is high, but the yield is not obvious example, such as flourish wheat plants, And seed yield is very low in order to achieve high utilization of nitrogen fertilizer, yield stimulation effect is obvious, you need to pay attention to the balanced supply of various nutrients from this point of view, the experimental study of adequate supply of phosphorus and potassium elements, to improve Effect of Nitrogen Utilization.
