Organic water-soluble fertilizer and preparation method

Abstract

The invention discloses organic water-soluble fertilizer and a preparation method. The organic water-soluble fertilizer is prepared from the following raw materials in parts by weight: 50-60 parts of lactic acid fermentation residues, 45-55 parts of amino acid, 20-30 parts of humic acid, 30-40 parts of ammonium dihydrogen phosphate, 40-50 parts of potassium nitrate, 20-30 parts of urea, 30-50 parts of calcium carbonate powder, 6-8 parts of glucose, 20-30 parts of starch, 3-5 parts of alginic acid, 13-16 parts of hydroxyethylcellulose, 3-6 parts of hydrogen peroxide, 2-6 parts of sodium stearate, 10-14 parts of bentonite, 6-9 parts of styrene, 13-16 parts of methacrylic acid, 3-4 parts of dimethyl formamide, 8-12 parts of astragalus polysaccharide, 4-8 parts of hypericin, 5-7 parts of hydroxyethyl cellulose, 3-5 parts of potassium fulvate and 60-75 parts of water. The organic water-soluble fertilizer has the advantages that soil organic matter can be increased, and emission of greenhouse gas is reduced; soil fertility is improved; the carbon and nitrogen ratio of soil is increased, and number and breeding of beneficial microorganisms are increased; soil permeability is improved, soil microbial flora is increased, and soil is improved; the soil pH is adjusted; heavy metals and pesticide residues in soil can be adsorbed and passivated, and damaged soil is remedied.

Description

technical field [0001] The invention relates to an organic water-soluble fertilizer and a preparation method thereof. technical background [0002] Water-soluble fertilizer is a new type of fertilizer developed in my country in recent years. It has good water solubility and less impurities, and is suitable for fine irrigation and fertilization such as drip irrigation and sprinkler irrigation. With the continuous increase of human demand for food and the continuous consumption of natural resources, the area of ​​arable land available to humans is continuously decreasing, and the fertilizer resources and raw materials that can be mined and synthesized are continuously decreasing, making humans need to produce more per unit area of ​​arable land. crops or food products. In order to increase the crop yield per unit area, human beings continue to develop the use of dry and less rainy land, establish irrigation facilities in these areas and the original rain-fed agricultural ar...

Problems solved by technology

The existing water-soluble fertilizer technology has many defects: if the nutrients contained are not comprehensive, it cannot supplement organic nutrients or organic matter for crops or soil, the effective nutrient content is low, and the nutrient structure is unreasonable, so it cannot provide balanced nutrients for crops
