Preparation method of special organic compound fertilizer for fast-growing forests

Abstract

The invention relates to the technical field of preparation of fertilizers for fast-growing forests, and discloses a special organic compound fertilizer for fast-growing forests. The special organic compound fertilizer for the fast-growing forests is prepared from the following raw materials in parts by weight: 400-500 parts of livestock and poultry manure, 20-60 parts of agricultural rare earth,0.2-0.3 part of a fertilizer leavening agent, 6-12 parts of biological functional bacteria liquid, 80-100 parts of urea, 50-70 parts of calcium magnesium phosphate fertilizer, 10-14 parts of monoammonium phosphate, 30-50 parts of potassium chloride, 0.6-0.8 part of zinc sulfate heptahydrate, 0.2 part of copper sulfate pentahydrate, 1.3 parts of borax, 5 parts of humic acid, 0.5 to 3 parts of a water-retaining agent, 0.2-2 part of an anti-continuous cropping agent and 8-12 parts of a fertilizer adhesive. According to the preparation method of the special organic compound fertilizer for the fast-growing forests, an organic fertilizer and an inorganic fertilizer are mixed, so eucalyptus can absorb required elements, the use amount of the fertilizer is reduced, the normal growth of the eucalyptus is ensured, and cost is saved; and organic fertilizer and inorganic fertilizer particles are respectively used as slow-release and controlled-release fertilizers, so the compound fertilizer is noteasy to lose, the lasting time of fertilizer efficiency is long, and the growth quality of the eucalyptus is improved.

Description

technical field [0001] The invention relates to the technical field of fast-growing forest fertilizer preparation, in particular to a preparation method of organic compound fertilizer special fertilizer for fast-growing forest. Background technique [0002] In order to cope with the large demand for trees in the industrial papermaking and wood processing fields, resulting in the reduction of forest area and the destruction of ecology and soil and water balance, people have implemented measures for fast-growing forests, that is, artificial forests with short rotation cycles. Well, the high survival rate of afforestation and other excellent characteristics can meet the needs of industrial papermaking and wood processing fields. Eucalyptus grows fast and is one of the most commonly used varieties for fast-growing forests. [0003] However, the rapid growth of eucalyptus is inseparable from the demand for fertilizers. Because eucalyptus has a high demand for fertilizers, it not ...

Problems solved by technology

[0003] However, the rapid growth of eucalyptus is inseparable from the demand for fertilizers. Because eucalyptus has a high demand for fertilizers, it not only needs to absorb elements such as nitrogen, potassium, phosphorus, calcium, magnesium and sulfur, but also needs to supplement and absorb various medium and trace mineral elements. Boron, zinc, iron, copper, manganese and other elements, these elements affect the growth quality of eucalyptus, and when the existing various mixed fertilizers are applied, the amount of fertilization will be large, unnecessary elements will be wasted, and it will easily be caused by rainwater. The fertilizer loss rate increased and the fertilizer effect time was short, which affected the growth quality of eucalyptus, resulting in low economic benefits of fast-growing forests.
