Technical Field

Background
The peat mainly comprises woody peat, herbaceous peat, moss peat and the like, wherein the woody peat is obviously superior to the herbaceous peat in terms of humic acid content. The woody peat is formed by the residues of woody plants, most of which are formed under the condition of eutrophic swamp, and the residues are mainly the woody plants such as birch, spruce and the like, and have brown, dark brown and blocky structures. Compared with other two kinds of peat, the woody peat is characterized by high carbon content (up to 60-65%), high content of humic acid (about 43-55%), high content of fulvic acid and water-insoluble substances (lignin and humic black), low content of water-soluble substances, hemicellulose and cellulose, and relatively high content of humic acid and peat wax. The difference of the conversion rate and the activity of humic acid is larger for different weathered coal raw materials and activation processes.
At present, the humic acid extraction process mainly comprises an acid extraction agent method, an alkali extraction agent method, an organic solvent extraction method and a microorganism dissolution method. The microbial dissolution method of humic acid has the characteristics of clean conversion of humic acid, high biochemical property of humic acid products and mild reaction conditions, but also has the defects of long production period, low humic acid product rate and easy metamorphosis and invalidation of microorganisms. The process of converting molecular humic acid into anionic humic acid in solution is called as dissociation or ionization, and generally refers to dissociation of carboxyl, the molecular humic acid is insoluble in water and low in activity, and only the humic acid dissociated into anionic humic acid can be absorbed by plants to play a role.
The common humic acid water-soluble fertilizers on the market are mostly prepared by adding solid humic acid raw materials and functional chemical fertilizers, and the produced humic acid water-soluble fertilizers have poor humic acid activity, high production cost and general product effect.
CN103601597B discloses a preparation method of a humic acid compound fertilizer prepared by peat fermentation, which comprises the steps of firstly inoculating peat into a mixed bacterial liquid for fermentation, then carrying out fine chelation reaction with plant ash, slaked lime and seaweed, and finally carrying out emulsification reaction, so that the absorption efficiency of crops on nutrition is enhanced.
CN111499457A discloses a preparation method of peat humic acid type functional microbial fertilizer, which comprises the steps of granulating peat humic acid, amino acid, organic materials, nitrogen phosphorus potassium fertilizer, manganese sulfate and silicon dioxide, preparing a compound microbial agent, and mixing the above to obtain the peat humic acid type functional microbial fertilizer, comprehensively improving the disease resistance and disease prevention capability of plants, obtaining quick-acting phosphorus and quick-acting nitrogen, and enhancing the growth of the plants. The peat adopts an organic solvent extraction method, the preparation steps are complex, and the activity of humic acid is low.
CN101024590B discloses a preparation method of a humic acid-containing water-soluble fertilizer, which comprises the steps of carrying out potassium hydroxide extraction on raw material peat containing humic acid to prepare a humic acid solution, then adding urea, monopotassium phosphate, boric acid and ammonium molybdate to dissolve the humic acid solution, finally reacting complexing agent with ferrous sulfate, copper sulfate and the like, and emulsifying the reaction product to obtain the humic acid water-soluble fertilizer.

Carrying out fertilizer efficiency test detection on the harvested celery, measuring and recording the plant height, stem thickness and single plant weight of the celery, carrying out data processing on repeatability detection data, wherein all results are average values after parallel data processing, Excel is adopted among the parallel data for statistics, and SPSS17.0 software is used for carrying out significance analysis processing to determine the significance level of 0.05;
wherein, the letters a, b and c in the detection data result are obtained according to the analysis of single-factor variance in SPSS17.0 software, and the meaning is expressed as follows: whether there is a significant difference in data difference between groups; the SPSS automatically calculates the statistical value, if P is less than the significance level of 0.05, the control variable is considered to have significant difference in the overall means under different levels, otherwise, no difference exists. For example: a and a represent no significant difference, a and b represent significant difference, b and c represent significant difference, and a and ab represent insignificant difference.
The data of the test results after treatment are shown in table 2, where the values are the mean ± variance, and n is 5; different letters in the same column indicate significance differences (P < 0.05, n ═ 5), P indicates significance level, n is the number of parallel experiments:

Meanwhile, in 7/15/2020, harvesting celery in a subarea manner, weighing the harvested celery, and carrying out statistical analysis on the yield of each group of test fields, wherein the statistical result is shown in table 3, the values in the table are the mean value plus or minus variance, and n is 5; different letters in the same column indicate significance differences (P < 0.05, n ═ 5), P indicates significance level, n is the number of parallel experiments:
TABLE 3 celery growth and yield comparison
As can be seen from Table 2, the application of humic acid in water has significant effects in plant height, stem thickness and weight per plant. The water flush fertilizer of the invention has obvious difference to the commercial fertilizer and the clear water contrast, and the effect is obvious.
As can be seen from Table 3, the yield of celery can be remarkably increased by both the commercially available humic acid water flush fertilizer and the humic acid water flush fertilizer of the invention, but the yield increase effect of the humic acid water flush fertilizer of the invention is more obvious, and the yield of the humic acid water flush fertilizer of the invention is increased by 3.9% compared with the commercially available humic acid water flush fertilizer and increased by 10.9% compared with clear water.
In addition, when the celery is harvested, the celery which is applied with the humic acid water flush fertilizer of the embodiment of the invention has uniform and regular growth, basically consistent stem thickness, thick petiole, emerald green color and better commodity; the plants of the celery which are commercially available and treated by humic acid water flush fertilizer and clear water have poor growth and stem thickness uniformity and general commodity; the humic acid water flush fertilizer disclosed by the invention is used on celery, and has an obvious improvement effect on biological properties of celery such as plant height, stem thickness and single plant weight.
Of course, the foregoing is only a preferred embodiment of the invention and should not be taken as limiting the scope of the embodiments of the invention. The present invention is not limited to the above examples, and equivalent changes and modifications made by those skilled in the art within the spirit and scope of the present invention should be construed as being included in the scope of the present invention.
