Embodiment 1

[0056] The preparation of the humic acid compound fertilizer prepared by embodiment 1 peat fermentation

[0057] The preparation steps are divided into three steps: peat fermentation, fermentation chelation and emulsification reaction;

[0058] (1) Peat fermentation

[0059]Crush the peat powder containing 40-45% humic acid to below 100 mesh, add molasses according to the mass ratio of peat:molasses = 100:1, add the mixed bacterial solution until the water content of the mixture is 80%, at 27-33°C Ferment for 5. days to get fermented peat;

[0060] (2) Chelation reaction

[0061] In the reaction kettle, add plant ash and slaked lime into deionized water and stir thoroughly. After 1 hour, add seaweed essence extracted by alkali method, stir thoroughly for 30 minutes, then add fermented peat, and fully react at a temperature of 70°C until pH=6.0 ~7.2, the reaction stops, take the supernatant; the mass ratio of plant ash, slaked lime and deionized water is 10:4:49;

Embodiment 2

[0085] The preparation of the humic acid compound fertilizer prepared by embodiment 2 peat fermentation

[0086] The preparation steps are divided into three steps: peat fermentation, fermentation chelation and emulsification reaction;

[0087] (1) Peat fermentation

[0088] Crush the peat powder containing 40-45wt% humic acid to less than 100 mesh, add molasses according to the mass ratio of peat:molasses=100:1, insert the mixed bacterial liquid until the water content of the mixture is 90wt%, and ferment at .33°C 5. Days to get fermented peat;

[0089] (2) Chelation reaction

[0090] In the reaction kettle, add plant ash and slaked lime into deionized water and stir thoroughly. After 1 hour, add seaweed essence extracted by alkali method, stir thoroughly for 30 minutes, then add fermented peat, and fully react at a temperature of 60°C until pH=6.0~ 7.2, stop the reaction, take the supernatant; the mass ratio of plant ash, slaked lime and deionized water is 15:2:40;

Abstract

The invention relates to a humic acid compound fertilizer prepared by peat fermentation and a preparation method thereof. The preparation method includes: smashing peat powder, adding molasses according to a ratio, then introducing a mixed bacterial solution, and conducting fermentation to obtain fermented peat; adding plant ash and slaked lime into water and stirring them fully, adding algae essence, then adding the fermented peat to let them fully react, then taking the supernatant; leading the supernatant into an emulsification tank, adding urea, potassium dihydrogen phosphate, magnesium sulfate, diethyl aminoethyl hexanoate and 5-nitroguaiacol sodium salt in order, and performing emulsification. According to the invention, the content of humic acid, water soluble nitrogen, phosphorus and potassium nutrients can be effectively enhanced, and in the process of fermentation, amino acid and other small molecule organics beneficial to plant growth are produced, and can polymerize with algal polysaccharide, alginic acid and the like in algae essence, the organic molecular polymers can undergo chelation with N, P, K and the like so as to generate chelating molecules that has biological activity and are easily absorbed by plants. Thus, the absorption efficiency of crops on nutrients can be enhanced, and the fertilizer loss is effectively reduced.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a humic acid compound fertilizer prepared by peat fermentation and a preparation method thereof. Background technique [0002] Chemical fertilizers have made significant contributions to the development of modern agriculture, but the long-term use of chemical fertilizers and pesticides, firstly, causes a lot of waste of non-renewable energy; secondly, chemical substances kill beneficial animals and microorganisms, breaking the ecological balance of agriculture, It leads to a decrease in fertility, soil compaction, a decrease in crop quality, and environmental pollution such as food and groundwater is becoming more and more serious. According to the analysis of relevant experts, the excessive use of chemical fertilizers leads to economic losses caused by water pollution accounting for 1.46% to 2.84% of GDP; the direct economic losses caused by China's agricultural non-point source pollution account...
