| 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，在习惯喷肥量的情况下，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，有效地弥实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，特别施用马铃薯上的肥效及其利用率要高于尿素。

| Abstract: | Long effect NH 4 HCO 3 was applicated to the main dryland crops i.e. wheat and potato. With normal management, the utility is 0.8 to 9.1 points higher than that of the common NH 4HCO 3. The effective period is double. So the shortage of N in the late stages of growing season has been compensated. Dressing same quantity of N,the fertility of long effect NH 4HCO 3 is much higher than that of urea. Its fertility and utility is even higher than urea when applicated to potato. |
