A metal-organic framework material fertilizer and a preparation method therefor. The novel fertilizer consists of nutrient molecules and external frameworks thereof, and is characterized in that the external frameworks are formed by coordination of inorganic metal ion clusters to organic joints under hydrothermal conditions. The metal-organic framework materials comprise two types, i.e., zinc-free and zinc-containing. The hydrothermal synthesis conditions of the novel metal-organic framework material fertilizer are that : the reaction temperature is 100癈, the reaction time is 24 h, the heating rate of the reactor is 2 癈/min, and the speed of the stir bar is 120 revolutions per minute. The nutrient contents of the novel fertilizer of the present invention are as follows : compound I : N : 4-5%, and P : 16-20%; and compound II : N : 5-7%, P : 15-18%, and Zn : 2-3%. The result of a soil cultivation test shows that the novel metal-organic framework material fertilizer of the present invention has the advantage of good nutrient controlled release and improves the utilization rate of nutrients.
