本试验是为了研究在氨化处理成熟的海岸狗牙根时利用尿素作为氨源的可行性。处理的方法包括:不添加尿素(对照组);在鲜草中添加结晶尿素使牧草干物质中尿素—氮的含量分别为1.5%(第一组)和3.0%(第二组);在鲜草中添加50%的尿素溶液使牧草干物质中尿素—氮的含量分别为1.5%(第四组)和3.0%(第三组);在鲜草中添加 The purpose of this experiment was to investigate the feasibility of using urea as the ammonia source during ammonification of mature Bermudagrass. The treatments included: no urea added (control group); addition of crystalline urea to fresh grass resulted in a urea-nitrogen content of 1.5% (first group) and 3.0% (second group) The addition of 50% urea to the grass made the urea-nitrogen content of forage dry matter 1.5% (fourth group) and 3.0% (third group) respectively;
