摘要: 长效碳铵在阴山丘陵区主要作物小麦和马铃薯上使用,在习惯施肥量的情况下,比普通碳铵的氮肥利用率提高8.8~9.1个百分点。肥效期比普通碳铵延长一倍左右,有效地弥补了普通碳铵后期脱肥的不足。在等氮量情况下,长效碳铵不仅远远超过普通碳铵的肥效,且与尿素的肥效基本相近,特别施用在马铃薯上的肥效及其利用率要高于尿素。

关键词: 阴山丘陵区, 旱地农业, 长效碳铵, 肥效, 肥料利用率

Abstract: Long effect NH4HCO3 was applicated to the main dry land crops i .e.wheat and potato.With normal management,the utility is 0.8 to 9.1 points higher than that of the comm on NH4HCO3.The effective period is double.So the shortage of Nin the late stages of growing season has been com pensated.Dressing same quantity of N,the fertility of long effect NH4HCO3 is much higher than that of urea.Its fertility and utility is even higher than urea when applicated to potato.

Key words: Fertility, Utility, NH4HCO3, Dryland farming, Yinshan hillyarea
