Special mixing coated fertilizer for base fertilizer of vegetables and preparation method thereof

Abstract

The invention discloses a special mixing coated fertilizer for a base fertilizer of vegetables. The special mixing coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 46-50 parts of cottonseed hull, 38-43 parts of coconut shell, 56-60 parts of bagasse, 50-56 parts of sweet potato stems, 3-6 parts of eucalyptus oil, 14-17 parts of sodium carboxymethylcellulose, 2-3 parts of insoluble sulfur, 26-29 parts of plant ash, 10-14 parts of coal gangue powder, 15-22 parts of ammonium hydrogen phosphate, 18-24 parts of potassium sulphate, 85-95 parts of pig manure, 6-8 parts of EM fungicide, 8-10 parts of soil modifier and a proper amount of water. The fertilizer disclosed by the invention is reasonable in formula, adopts organic fertilizers such as cottonseed hull, bagasse and the like to ferment, can meet the requirements for growth of crop branches, stems and leaves, fruits and grains, is friendly to environment, and slow to release fertility, and has moisture-holding and fertilizer-holding functions, inorganic fertilizers, nitrogen, phosphorus and potassium are added at a proper ratio, waste materials can be changed into treasures, and the yield and the quality of the vegetables are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special mixed coated fertilizer for vegetable base fertilizer and a preparation method thereof. Background technique [0002] 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, polyethylene and elemental sulfur. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. It is suitable for crops with high economic value, long growth period, large amount of fertilizer but inconvenient to fertilize in batches, and h...

Problems solved by technology

Lead to soil compaction, crop production reduction, ecological environment damage, especially water eutrophication, affecting human and animal health

For a long time, people have formed the status quo of applying chemical fertilizers and not paying attention to the application of organic fertilizers, which not only reduces soil productivity and vegetable quality, but also greatly damages the ecological environment.
