秋冬低温季节施碳铵效果好,碳酸氢铵施碳铵效果好于尿素。

—is fast肥:ammonium bicarbonate is an ammonium nitrogen肥that can be directly absored and used by crops after being applied to the soil.尿素属于酰胺类铵肥,需要由土壤中尿素细菌分泌的尿素酶转化成铵态氮进行根系吸收。在这里,尿素转化率主要取决于当时的土壤温度。在正常情况下,施于土壤中的尿素全部转化为氨氮。当地面温度为低摄氏度时,需要7-10天;当地面温度为2摄氏度时,需要4-5天;当地面温度为3摄氏度时,只需要2-3天。由此可见,冬、早春季节对作物进行了表面处理,碳酸氢铵的施用速度快于尿素。如果施用尿素,由于肥料的缓慢作用,它往往会影响作物的生长。

_is a high utilization rate:ammonium bicarbonate is neatly volatilized at temperatures under 2o degrees occulture.将铵离子施于土壤后,可迅速被土壤胶体吸附,其吸附为尿素。时代。因此,水不容易流失。尿素在土壤中应用时,在转化成铵态氮之前,以分子状态存在,很难被土壤胶体吸附,容易流失。

The third effect is good:some people have done experimentals,and the application of ammonium bicarbonate in the winter meat field is more than 1.5 times higher than than in the high temperature season.
