For patients with phobia, the use of urea or ammonium bicarbonate for winter crops is a big problem. Let's take a look at the specific analysis. Crops are fertilized in low temperature seasons such as winter and early spring, and the application of ammonium bicarbonate is better than urea. Fast fertilizer effect. Ammonium bicarbonate belongs to ammonium nitrogen fertilizer. It can be directly absorbed and utilized by crops after being applied to soil. Urea belongs to ammonium amide. It needs to be converted into ammonium nitrogen by urease secreted by urea bacteria in soil to absorb roots. 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. High utilization rate. 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. The effect is good. It has been tested that the application of ammonium bicarbonate in winter wheat fields is 1 to 1.5 times higher than that in high temperature seasons.
