The crop is fertilized in the low temperature season in autumn and winter, and the application of ammonium bicarbonate is better than the application of urea. First, the fertilizer is fast. Ammonium bicarbonate is an ammonium nitrogen fertilizer that can be directly absorbed and utilized by crops after being applied to the soil. Urea belongs to the ammonium amide fertilizer, which needs to be converted into ammonium nitrogen by urease secreted by urea bacteria in the soil for root absorption. Here, the rate of urea conversion depends mainly on the soil temperature at the time. Under normal circumstances, all urea applied to the soil is converted to ammonium nitrogen, which takes 7 to 10 days at a ground temperature of 10 ° C, 4 to 5 days at 20 ° C, and only 2 to 3 days at 30 ° C. It can be seen that the crops are topdressed in winter or early spring, and the application of ammonium bicarbonate is faster than urea; if urea is applied, it tends to affect the growth of the crop because of the slow effect of fertilizer. Second, the utilization rate is high. Ammonium bicarbonate is rarely volatilized at temperatures below 20 ° C. After being applied to the soil, ammonium ions can be rapidly adsorbed by the soil colloid, and its adsorption force is 8 times that of urea. Therefore, it is not easy to lose with water. When urea is applied to the soil, it exists in a molecular state before it is converted into ammonium nitrogen, which is difficult to be adsorbed by the soil colloid and is easily lost. Third, the effect is good. Some people have done experiments to apply ammonium bicarbonate in winter wheat fields, and the effect is 1 to 1.5 times higher than that in high temperature seasons.
