摘要
采用25℃恒温试验条件,研究了木质素铵肥料在水中和土壤中的氮缓释效果,同时用尿素作对照来探讨其氮释放量和释放动力学特征,结果表明,木质素铵中氮的释放较尿素缓慢。
Under the testing condition of steady temperature of 25℃ , this paper researches the nitrogenated slow release efficiency of wood fibre ammonium fertilizer in water and earth, and simultaneously com pared with urea, studies the amount and the dynamic characteristics of nitrogenated release. The result shows the nitrogenated release of wood fibre ammonium was slower than that of urea.
