Production method of organic liquid fertilizer

Abstract

The invention provides a production method of an organic liquid fertilizer. The production method comprises the following steps: uniformly stirring 100-150 parts of excrement, 50-80 parts of straw, 30-50 parts of aquatic plants, 100-200 parts of biogas slurry and 0.5-2 parts of a microbial agent, performing composting fermentation for 20-30 days at room temperature so as to obtain a fermentation material, performing stirring extraction by using a sodium carbonate aqueous solution at 80-90 DEG C, performing filtering, performing evaporation concentration on the obtained filtrate till the density is 1.1-1.3 so as to obtain an extract, adding 0.1-0.2 part of a trace element, 5-10 parts of natural active organic matter, 1-5 parts of a natural surfactant and 0.5-2 parts of a soil improver, anduniformly mixing the components at the temperature of 45-60 DEG C, so as to obtain the organic liquid fertilizer. The fertilizer prepared by using the method has a good use effect and is an efficientenvironment-friendly organic liquid fertilizer.

Description

technical field [0001] The invention belongs to the field of liquid fertilizers, in particular to a production method of organic liquid fertilizers. Background technique [0002] Soil is composed of minerals, organic matter and soil microorganisms. The transformation of mineral nutrients in minerals and organic nutrients in organic matter is mainly completed by microorganisms in the soil. Microorganisms are active factors in soil development. The life activities of microorganisms in the soil are based on soil organic matter, transforming soil nutrients, improving soil fertility, and providing effective ingredients for plant growth and development. Conversely, as the soil continues to mature and its fertility increases, it also promotes the reproduction and growth of microorganisms, thus forming a benign ecological balance of the soil. However, due to the large-scale application of chemical fertilizers over the years, the enriched inorganic elements in the soil have increa...

AI Technical Summary

Problems solved by technology

However, due to the large-scale application of chemical fertilizers over the years, the enriched inorganic elements in the soil have increased, resulting in a sharp decrease in soil organic matter and beneficial microorganisms, resulting in soil compaction, reduced water and fertilizer retention capacity, hindered transformation of substances and capabilities, and continuous decline in fertilizer utilization. , a large amount of chemical fertilizers accumulate in the soil, causing serious environmental pollution, water quality decline, serious pollution of agricultural products, the entire agricultural ecological environment and people's living environment are affected

[0003] Most of the existing organic fertilizers are piled and fermented farmyard manure, but the disadvantages of applying all organic fertilizers are low fertilizer efficiency and unbalanced nutrients, which make it difficult to meet the requirements of crop growth and disease resistance

At present, my country's planting industry is gradually moving towards labor-saving, labor-saving, efficient and clean mechanized cultivation methods, and fertilization is also tending to be mechanized. New liquid fertilizers meet the needs of modern agricultural fertilization. Traditional organic fertilizer technology can no longer adapt to the needs of modern agriculture. develop

[0004] The quantity and nutrients of organic fertilizers in my country are about 18 million tons, accounting for only 34% of the total resources and 30% of the total nutrient input in farmland. The unused part has become the main source of environmental pollution. Some studies have shown that there are about 30% of the straw. 10% is incinerated, and about 10% is discarded in ditches; 25-30% of the excrement enters the water body, causing great pollution to the environment
