| Abstract: | The hydroxyapatite （HAPI as carrier materials, preparation of hydroxyapatite - urea slow-release compound fertilizer. Use of DMAB chromogenic method to detect the content of urea. Investigation and water ratio, temperature and pH value on the HAP - urea compounds the effect of nutrient release rate in the water. Compounds is dissolved in the water the best conditions of nutrient release rate. And water ratio of 1：20, temperature of 30℃, pH value of 7. |
