[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc.

[0003] Existing plant fertilizers generally use chemical fertilizers such as urea and potash fertilizers. Long-term application of chemical fertilizers will cause soil compaction, accelerate soil acidification, and increase toxic substances in the soil. In severe cases, it will lead to soil infertility and pollute the environment, which is not conducive to long-term use. Therefore, it is necessary to develop a plant fertilizer using extracts of natural materials as raw materials, so as to promote plant growth while avoiding environmental pollution. Summary of the invention

[0008] In order to achieve the above object, another embodiment of the present invention provides a novel plant fertilizer fermentation preparation method for preparing plant fertilizer, characterized in that it comprises the following steps:

[0009] 1) First, crush the corn stalks and struvite into powder;

[0010] 2) Stir and mix the powders of wood ash, corn straw and struvite;

[0011] 3) Pour the biogas slurry into the mixture of wood ash, corn straw and struvite and stir until it is evenly dispersed;

[0012] 4) Add yeast and sugar to the mixture of biogas slurry, wood ash, corn straw and struvite, then stir evenly and heat until the yeast fully ferments the mixture;

[0013] 5) After the fermentation in step 4) stops, add Bacillus subtilis and Enterococcus faecalis in sequence and stir and ferment;

[0014] 6) After the fermentation in step 5) stops, a fertilizer block is obtained, which is added to a granulator for granulation.

[0017] The present invention has the following advantages:

[0018] 1. This new type of plant fertilizer uses pure natural organic matter such as wood ash, corn stalks, biogas slurry and guano as the base material of the fertilizer. It is low-cost and rich in nitrogen, phosphorus and potassium, which can effectively meet the nutrients needed for most current plant cultivation. In addition, the fertilizer has been fermented by yeast, Bacillus subtilis and Enterococcus faecalis, which kills most harmful bacteria and improves the activity of the fertilizer, so that the fertilizer can give full play to its value.

At the same time, the biogas slurry is first stirred evenly before fermentation, which can provide sufficient moisture and fully activate the organic matter in the biogas slurry, thereby improving its activity and improving the overall effect of the fertilizer. DETAILED DESCRIPTION

[0020] The present invention is further described below, but the protection scope of the present invention is not limited to the following description.

[0021] Example 1: A novel plant fertilizer comprises the following ingredients: 10 parts of wood ash, 30 parts of corn stalks, 25 parts of biogas slurry, 30 parts of struvite, 5 parts of yeast, 5 parts of Bacillus subtilis, 5 parts of Enterococcus faecalis, and 10 parts of white sugar.

[0022] This embodiment reduces the content of wood ash, increases the content of corn straw and biogas slurry, increases the organic matter content, reduces the alkali content, and is more suitable for fertilizing alkaline soil.

[0023] Example 2: A new type of plant fertilizer comprises the following ingredients: 15 parts of wood ash, 20 parts of corn stalks, 20 parts of biogas slurry, 35 parts of struvite, 10 parts of yeast, 10 parts of Bacillus subtilis, 10 parts of Enterococcus faecalis, and 10 parts of white sugar.

[0024] This embodiment increases the content of wood ash, thereby making the nitrogen, phosphorus and potassium content higher, and at the same time increases the alkalinity of the fertilizer, making it suitable for use in balanced acidic soils, and can effectively balance the pH value, greatly improving the soil condition.

[0025] Embodiment 3: A novel method for preparing plant fertilizer by fermentation, comprising the following steps:

[0026] 1) First, crush the corn stalks and struvite into powder;

[0027] 2) Stir and mix the powders of wood ash, corn straw and struvite;

[0028] 3) Pour the biogas slurry into the mixture of wood ash, corn straw and struvite and stir until it is evenly dispersed;

[0029] 4) Add yeast and sugar to the mixture of biogas slurry, wood ash, corn straw and struvite, then stir evenly and heat until the yeast fully ferments the mixture. The fermentation time is 5 hours and the heating temperature during fermentation is 25 degrees Celsius.

[0031] 6) After the fermentation in step 5) stops, a fertilizer block is obtained, which is added to a granulator for granulation.

[0032] This embodiment adopts a lower fermentation temperature, and yeast, Bacillus subtilis and Enterococcus faecalis can ferment slowly at the most comfortable temperature. Although the fermentation time is prolonged, it also enables the fertilizer to be fermented most fully, improves the utilization rate, and improves the fermentation effect.

[0033] Embodiment 4: A novel method for preparing plant fertilizer by fermentation, comprising the following steps:

[0034] 1) First, crush the corn stalks and struvite into powder;

[0035] 2) Stir and mix the powders of wood ash, corn straw and struvite;

[0036] 3) Pour the biogas slurry into the mixture of wood ash, corn straw and struvite and stir until it is evenly dispersed;

[0037] 4) Add yeast and sugar to the mixture of biogas slurry, wood ash, corn straw and struvite, then stir evenly and heat until the yeast fully ferments the mixture. The fermentation time is 2 hours and the heating temperature during fermentation is 36 degrees Celsius.

[0038] 5) After the fermentation in step 4) stops, add Bacillus subtilis and Enterococcus faecalis in sequence and stir and ferment for 24 hours at a temperature of 30 degrees Celsius;

[0039] 6) After the fermentation in step 5) stops, a fertilizer block is obtained, which is added to a granulator for granulation.

[0040] This embodiment adopts a higher fermentation temperature, which greatly increases the fermentation speed and can effectively improve the production efficiency.

[0041] Experimental example:

[0042] In 2023, two experimental fields A and B in the northern region, each with an area of ​​5 mu, were planted with winter wheat. The A experimental field used the new plant fertilizer prepared in Example 1, and the B experimental field used traditional inorganic compound fertilizer. After a complete growth cycle of wheat, the following experimental results were obtained:

[0043]

[0044]

[0045] According to the experimental examples, the new plant fertilizer is slightly inferior to the traditional compound fertilizer in terms of per-acre yield, but the fertilizer residual pollution rate is low, and the soil is not compacted. The soil fertility is well maintained, ensuring that the soil fertility is not lost.

[0046] In summary, by using pure natural organic matter such as wood ash, corn straw, biogas slurry and struvite as the base material of fertilizer, it is low in cost and rich in nitrogen, phosphorus and potassium, which can effectively meet the nutrients needed for most plant cultivation at present. Moreover, the fertilizer has been fermented by yeast, Bacillus subtilis and Enterococcus faecalis multiple times, which kills most harmful bacteria and improves the activity of the fertilizer, so that the fertilizer can give full play to its value. At the same time, the fertilizer is rich in organic matter, which can improve the nitrogen fixation effect of the soil, prevent the decline of soil fertility, and prevent soil compaction. It also degrades quickly after decomposition, greatly reducing pollution to the environment. By first using yeast and white sugar for preliminary fermentation, most of the miscellaneous bacteria and harmful bacteria in the fertilizer base material can be eliminated, and the fertilizer can be prevented from being contaminated by miscellaneous bacteria, ensuring the smooth progress of subsequent fermentation. At the same time, stirring the biogas slurry evenly before fermenting can provide sufficient water, and at the same time, the organic matter in the biogas slurry can be fully activated, its activity can be improved, and the overall effect of the fertilizer can be improved.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
