Abstract

The invention discloses sustained-release compound fertilizer prepared from biogas residues for citrus. The sustained-release compound fertilizer prepared from the biogas residues for the citrus is prepared from the following raw materials by compounding: 58-76 parts of a coating material, 300-550 parts of fertilizer granules and 30-44 parts of adjuvants, wherein the coating material is prepared from a sustained-release agent and a binder; the fertilizer granules comprise the biogas residues, ammonium carbonate, potassium phosphate, potassium chloride, calcium chloride, magnesium borate, zincchloride, ferric chloride, manganese sulfate, copper sulfate and organic acid; the adjuvants comprise an antibacterial agent, a curing agent, a conditioner, an oxidant and a coupling agent. The compound fertilizer contains various nutrient elements needed for citrus growth, is moderate in sustained release rate and lasting and stable in efficiency, fertilizer using efficiency can be increased effectively, and fertilization times can be reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a citrus slow-release compound fertilizer using biogas residue. 【Background technique】 [0002] During the citrus planting process, a large amount of nutrients, including organic nutrients and inorganic nutrients, need to be supplemented. Since most of the market is pure organic or inorganic fertilizers, in the citrus planting management, it is necessary to rationalize the organic and inorganic nutrients required by citrus. Matching can fully meet the needs of citrus for various nutrients. With the rise of organic agriculture, the use of organic fertilizers, rational application of inorganic fertilizers and formula fertilizers are often advocated, and fertilization is guided according to citrus growth and climate characteristics. Due to the simple use of fertilizers, it is easy to cause fertilizer loss, especially in special soils such as erosion lan...
