Embodiment 1

[0027] The high-efficiency micro-humic acid fertilizer used in this example is formed by adding humic acid after the biogas slurry is concentrated 10-20 times. In December 2015, a continuous comparison test was started, and different seasons, different raw material ratios, and The nutritional components and physical and chemical properties of the biogas slurry at different fermentation times were determined. The pH value and EC value of high-efficiency humic acid fertilizer were measured by METTLER TOLEDOSevenEasy acidity meter and DDBJ-350 portable conductivity meter; the contents of available nitrogen, phosphorus and potassium were measured by alkaline solution diffusion method, sodium bicarbonate method, ammonium acetate-flame photometer method; the organic matter content was determined by the dilution heat method; the humic acid content was determined by the method described in NY / T 1971. Taking the existing soilless cultivation and chemical fertilizers in the market as th...

Embodiment 2

[0043] The high-efficiency humic acid fertilizer used in this example is formed by adding humic acid after the biogas slurry is concentrated 10-20 times. At the end of February 2016, a continuous comparison test was started, and different seasons, different raw material ratios, and different fermentation times were collected in batches. The biogas slurry was tested for its nutritional components and physical and chemical properties. The pH value and EC value of high-efficiency humic acid fertilizer were measured by METTLER TOLEDO SevenEasy acidity meter and DDBJ-350 portable conductivity meter; the contents of available nitrogen, phosphorus and potassium were measured by alkaline solution diffusion method, sodium bicarbonate method, ammonium acetate-flame photometry Determination by meter method; organic matter content was determined by dilution heat method; humic acid content was determined by the method described in NY / T 1971. Taking the existing soilless cultivation and che...

Abstract

The invention belongs to the field of biogas slurry recycling, and in particular relates to efficient humic acid fertilizer prepared by using concentrated biogas slurry, and application of the efficient humic acid fertilizer. The nutrient content is increased by concentrating original biogas slurry; fine adjustment is carried out according to the content of the concentrated original biogas slurry; the efficient humic acid fertilizer is obtained by adding humic acid according to a proper ratio. The humic acid fertilizer can promote the formation of a soil structure and improve pore status; the humic acid fertilizer can improve the cationic absorption property of soil and the fertilizer preservation and supply capability of the soil; the humic acid fertilizer enhances a soil buffer system and improves acid soil; the humic acid fertilizer also can promote the activities of profitable soil microorganisms.

Description

technical field [0001] The invention belongs to the field of recovery and reuse of biogas slurry, and in particular relates to a high-efficiency humic acid fertilizer made from concentrated biogas slurry and its application. Background technique [0002] In recent years, my country's large-scale livestock and poultry farms have developed rapidly, and the number has increased rapidly. The large-scale livestock and poultry breeding is increasing at a rate of 3% to 5% per year, and the regionalization of development is obvious. The breeding area centered on the suburbs of the middle city. The ensuing problem of the rapid increase in the discharge of livestock and poultry manure has also become increasingly prominent. The annual production of livestock and poultry manure in the country has exceeded 2.5 billion tons, which is 2.7 times that of industrial waste. [0003] As we all know, biogas slurry is an excellent fertilizer, which is rich in nitrogen, phosphorus, potassium and ...
