摘要
长效尿素为添加抑制剂的尿素新产品,抑制剂包括脲酶抑制剂和硝化抑制剂,它们可有效地减缓尿素水解进程,延长肥效期,提高氮素利用率,使农业达到增产、节肥和省工的综合效益。本文介绍了长效尿素的研制、生产、农业应用效果和施用技术。
Slow - releasing urea is a kind of new product of urea with deprssor. The depressor includes dicyanndiamide and nitro -lnhibitoss, which can effectively restrict the speed of the urea release in water, and increase the utilization rate of urea fertilizer. Hence,it has benefits for agricultural production by increasing yield, and saving fertilizer and manpower. The paper introduces the preparation and production of the new urea, and the technique for agricultural use.
