摘要
利用有机—无机 (矿物 )控释材料对碳酸氢铵进行改性 ,制成改性碳酸氢铵。盆栽试验结果显示 ,在等重条件下 ,改性碳酸氢铵较普通碳酸氢铵有较大幅度的增产。运用X射线衍射分析及红外光谱对改性碳酸氢铵的结构进行研究 ,发现其晶体结构发生较大的变化 ,差热分析结果也表明 ,改性碳酸氢铵的热分解温度比普通碳酸氢铵提高 30℃。这种晶体结构的变化增加了改性碳酸氢氨的稳定性 ,从而延长了其肥效并提高了 N的利用率。
We use organic-inorganic (minerals) controlled release material to modify ammonium bicarbonate and develop two new controlled release N fertilizers of modified ammonium bicarbonate. The result from potted plant shows that two modified ammonium bicarbonates are better than normal ammonium bicarbonate in the condition of equal weight. We also use XRD and IR to analyze the crystal structure of modified ammonium bicarbonate,which shows that the crystal structure changed greatly.The change of crystal structure increases the stability of modified ammonium bicarbonate,extends their fertile effect and increase the efficiency of N.
