Water-soluble organic fertilizer containing medium trace elements and preparation method of water-soluble organic fertilizer

Abstract

The invention discloses a water-soluble organic fertilizer containing medium trace elements. The water-soluble organic fertilizer comprises the following components, by weight percentage, 150-200 parts of maifan stone, 5-20 parts of a soil improvement fertilizer, 30-40 parts of trace elements, 16-25 parts of a composite biological agent, 20-40 parts of gypsum powder, 10-20 parts of ground phosphate rock, 10-15 parts of ferrous sulphate, 10-15 parts of aluminum sulfate and 10-20 parts of sulfur powder. Adverse reactions between elements and multiple ions can be effectively prevented, and the use ratio of a medium trace element fertilizer can be effectively increased. After the water-soluble organic fertilizer is applied to soil, the beneficial bacteria amount in the soil can be effectively supplemented, fixed nutrients in the soil are promoted to decompose, the fertilizer providing capability of soil is improved, and healthy growth of plants is ensured. Input of the fertilizer is reduced, the use ratio of the fertilizer is increased, the soil is improved, and the cost is saved.

Description

technical field [0001] The invention relates to a water-soluble organic fertilizer containing medium and trace elements and a preparation method thereof. Background technique [0002] Soil salinization has a relatively large damage to the physical and chemical properties of the soil, which is extremely unfavorable to the growth of many crops, and it is easy to cause the lack of seedlings or death of crops, thus hindering the development of agricultural economy. Due to the high salt content, low organic mass, and high pH in saline-alkali land, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface, and poor ventilation and water permeability. Severe cases can cause plant wilting, poisoning and root rot to die. In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easi...
