Chitosan controlled release fertilizer microspheres and preparation method thereof

The invention provides chitosan controlled release fertilizer microspheres and a preparation method thereof. The controlled release fertilizer consists of biodegradable chitosan, polyvinyl alcohol, sodium alginate and a chemical fertilizer. The preparation method comprises the following steps: dissolving chitosan in an acetic acid solution; dissolving the chemical fertilizer and polyvinyl alcohol in the chitosan acetic acid solution; adding an ion crosslinking agent to obtain microspheres; and putting the microspheres in a sodium alginate solution for ultrasonic vibration to form the chitosan controlled release fertilizer microspheres. In the process of crosslinking to form the microspheres, fertilizer molecules are adhered and wrapped in crosslinked network micropores of the chitosan microspheres, so that the solubility and releasing capacity of the fertilizer molecules are changed and nutrients are slowly released along with degradation of the chitosan microspheres. At the same time, a sodium alginate electrolyte membrane is wrapped on the surfaces of the microspheres, thereby reducing the burst release phenomenon of nutrients generated in the initial release stage. The controlled release fertilizer is simple in preparation process, relatively low in cost, environmentally friendly and non-toxic and suitable for industrial production.
