氮肥增效剂,国外又叫硝化抑制剂。它是美国在五十年代末首先研制成功的,同时掺入到化肥中进行农田试验。我国在七十年代初研制成功。随着化肥工业的发展,农业上使用的化肥量逐年增加,但由于利用率不高,加大了农业投资。为减少氮肥损失,提高利用率,多年来我们认真地进行了氮肥增效剂的研究及大面积示范,取得了良好的增产效果。一、氮肥增效剂的增产效果
Nitrogen synergist, also known as nitrification inhibitors. It was first successfully developed by the United States in the late 1950s and was incorporated into fertilizers for farmland testing. Our country was successfully developed in the early 1970s. With the development of fertilizer industry, the amount of fertilizer used in agriculture has increased year by year, but due to the low utilization rate, agricultural investment has been increased. In order to reduce the loss of nitrogen fertilizer and improve the utilization rate, over the years, we have seriously conducted research on nitrogen fertilizer synergists and large-scale demonstration and achieved good yield-increasing effect. First, the effect of nitrogen fertilizer synergist
