Abstract

The invention discloses a soil improvement type biological organic composite coated fertilizer which is characterized by being prepared from the following raw materials in parts by weight: 67-70 parts of human and animal excreta, 25-30 parts of riverway sludge, 8-10 parts of diatomite, 25-28 parts of diammonium phosphate, 12-15 parts of magnesium sulfate, 15-19 parts of potassium chloride, 45-49 parts of furfural residue, 40-45 parts of animal bone meal, 50-54 parts of rice husk, 35-40 parts of saw dust, 27-29 parts of urea, 3-5 parts of amino acids, 1-2 parts of sodium tetraborate, 7-8 parts of an EM fungicide, 7-9 parts of a soil improvement agent and a proper amount of water. The fertilizer disclosed by the invention is balanced in nutrition, contains inorganic elements and mineral substance components such as the riverway sludge and diatomite, the nutrient needed by plant growth is met, the soil is activated, and the water and fertilizer retaining properties of the soil are improved; and due to the addition of the soil improvement agent, the fertilizer has the effects of improving the efficiency and promoting plant nutrition absorption. According to the fertilizer disclosed by the invention, the urea melting and coating process is adopted, the slow-release effect is obvious, and the fertilizer efficiency is lasting.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a soil-improving bio-organic composite coated fertilizer and a preparation method thereof. Background technique [0002] Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have certain effects on the growth of crops, which requires effective soil improvement. Existing fertilizers for soil improvement can only see the impact of fertilizers on crops, but cannot effectively improve the soil. Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest. Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, p...
