Abstract

The invention provides a special controlled-release fertilizer for fast-growing eucalyptus and a preparation method thereof, belonging to the field of mixed fertilizers. The fertilizer comprises an outer wrapping layer consisting of rumen protected fat and inner fertilizer particles. The fertilizer particles are prepared by mixing the following components: urea, monoammonium phosphate, potassium chloride, calcium-magnesium phosphate powder, borax, copper sulfate, zinc sulfate, compound sodium nitrophenolate, polyglutamic acid, humic acid and an adhesive. The fertilizer has abundant and comprehensive nutritional ingredients, can satisfy the demands of eucalyptus on various nutrients in the normal growing process to accelerate the eucalyptus to grow fast, and has a good controlled-release effect, so that the loss of nutrients of the fertilizer is effectively reduced, and the utilization ratio of the fertilizer is improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special controlled-release fertilizer for fast-growing eucalyptus and a preparation method thereof. Background technique [0002] Eucalyptus is native to Australia, Indonesia and the Philippines. It grows rapidly and has wide adaptability. It is one of the world's three largest afforestation tree species. Eucalyptus has been introduced into my country for more than 100 years, and it has become a strategic tree species for fast-growing and high-yielding forests in southern China. Eucalyptus has excellent characteristics such as fast growth, straight stem, drought resistance, barrenness, etc. Generally, it can be harvested and utilized after 5-7 years of afforestation, and can be widely used in papermaking, wood-based panel industry, housing construction, furniture manufacturing, landscaping, etc. The economic benefits of eucalyptus are huge, and the economic return ra...
