Abstract

The invention discloses a eucalyptus controlled-release fertilizer and a preparation method thereof and belongs to the technical field of fertilizer preparation. The eucalyptus controlled-release fertilizer comprises, by weight, 60-160 parts of a coating material and 200-1400 parts of fertilizer granules. The eucalyptus controlled-release fertilizer is prepared in the steps such as crushing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling and coating. The eucalyptus controlled-release fertilizer has a moderate and stable controlled-release rate and balanced nutrition, is effective in decreasing fertilizer loss rate, increasing fertilizer utilization, promoting quick and healthy growth of eucalyptus and increasing the growth speed of eucalyptus; this fertilizer is also effective in preventing disease and pest damage, improving soil environment and maintaining eco-environmental friendliness.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a eucalyptus controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] Eucalyptus grows fast and has excellent materials. It is a short-cycle economic tree that is currently popularized and planted in China. Its wood is widely used in papermaking and fiber board processing. However, the demand for nutrients in the growth process of eucalyptus is greater than that of other tree species, so sufficient fertilizer must be applied to make eucalyptus grow normally. [0003] For this reason, some people have begun to study eucalyptus fertilizer at present. For example, the patent document (Application No.: 03139716.6) discloses a trace element fertilizer containing two or more of B, Cu, Zn, Mn, Fe and Mo elements for preventing and treating eucalyptus deficiency diseases. [0004] At present, more are compound fertiliz...
