据统计，目前我国碳控数量占氮肥总量的47％，仍是重要的氮肥品种，但其当季利用率一般比尿素约低10个百分点。本文通过室内模拟试验主要研究不同剂型碳铰在不同立类、土壤温度、水分、施肥深度下氨的挥发规律和田间条件下对不同作物的增产效果，为今后碳镇的合理施用提供依据
According to statistics, at present, China’s carbon-controlled quantity accounts for 47% of the total amount of nitrogen fertilizer, and is still an important nitrogenous fertilizer variety. However, the seasonal utilization rate is generally about 10% lower than that of urea. In this paper, indoor simulation tests mainly studied the volatilization of ammonia under different plant types, soil temperature, water and fertilizer depth, and the stimulation effect of different crops under field conditions with carbon hinges of different dosage forms, providing the basis for the rational application of carbon towns in the future
