滴灌复合肥磷酸脲的合成与肥效试验

Synthesis of Urea Phosphate,Compound Fertilizer for Drip Irrigation,and its Fertilizer Effect Experiment

研究了磷酸脲的合成及其在滴灌棉花的施用情况。结果表明 ,采用湿法磷酸合成磷酸脲不仅成本低 ,而且可提高肥料利用率 ,同时也可发挥滴灌技术定量可控优势 ,避免地下水污染 ,有良好的经济和社会效益。

A study is made of the synthesis of urea phosphate and its application on cotton by drip irrigation. The results indicate that the synthesis of urea phosphate from wet-process phosphoric acid not only is low in cost but also increases fertilizer utilization ratio,also gives full play to the superiority in quantitative controllability of drip irrigation,prevents the contamination of ground water,and gives excellent economic and social benefits.
