Abstract

The invention discloses a special slow release fertilizer for eucalyptus. The slow release fertilizer comprises a coated material and fertilizer granules, wherein the coated material is highly surface-activated mineral or natural macromolecular material; the fertilizer granules comprise an inorganic fertilizer, a ferment fertilizer, an aquatic fertilizer and an animal manure fertilizer; the inorganic fertilizer comprises urea, calcium superphosphate, potassium sulfate, potassium nitrate, zinc sulfate heptahydrate and copper sulfate pentahydrate; the ferment fertilizer is a fermented product of pitaya peels, litchi shells, longan seeds and bagasse; the aquatic fertilizer is a fermented product of fish bones, shrimp heads and crab shells; the animal manure fertilizer is a fermented product of animal manure. The invention further provides a preparation method for the special slow release fertilizer for the eucalyptus. Rich essential nutritive elements such as nitrogen, phosphorus, potassium and the like are scientifically combined, wastes of fruits teeming in Guangxi, aquatic products and animals are fully utilized and turned into wealth, and composting is performed for multiple times, so that an organic fertilizer rich in medium trace elements, amino acids, humic acids and organic matters is obtained; the special slow release fertilizer has a good water-retention effect and is friendly to environment.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special slow-release fertilizer for eucalyptus and a preparation method thereof. Background technique [0002] Eucalyptus is the general name of Eucalyptus in Myrtaceae. Because of its rapid growth and high economic benefits, it is widely planted in southern my country and is a strategic tree species in Guangxi. Eucalyptus trees are beautiful, evergreen in all seasons, and have strong drought resistance. They are suitable for street trees, windbreaks and sand-fixing forests, and landscaping trees. However, eucalyptus has a great demand for soil fertilizer, nutrients and water, so when fertilizing, we must grasp a basic principle: to pursue the minimum amount of fertilizer under the premise of satisfying the growth of eucalyptus. Reasonable fertilization is very important to improve the growth rate of eucalyptus . [0003] Since the soil in Guangxi generally lacks trace elements suc...
