尿基复混肥中添加磷矿粉的工艺及肥效研究

Process for Addition of Ground Phosphate Rock into Urea-Based Compound Fertilizers and Study of Fertilizer Efficiency

尿基复混肥中添加部分磷矿粉,既解决了肥料的结块问题,又能起到缓释作用。通过产品对油菜的肥效研究,阐述产品在酸性土壤上使用具有一定的经济效益。

The addition of ground phosphate rock into urea-based compound fertilizers not only solves the problem of fertilizer caking but also gives a slow-release result. By studying their fertilizer efficiency on rape it is shown that their application on acid soils brings about certainly economic benefit.
