| Abstract: | Introduced the effection to the ratio of the capsule heart release speed of the slow-release fertilizer-urea-chitosan of the microcapsule of the method of operation and study the release speed in neutral water,weak acid or weak base.The results show that the effection to release speed was controlled main of the proportion of the capsule wall and the capsule heart,and the density of the chitosan of wall material was suitable for 3%. |

| Keywords: | microcapsule release speed wall material density of the chitosan |
