Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a fertilizer beneficial to the growth of soil microorganisms and a preparation method thereof.
Background
China is a big agricultural country, and 22% of people are cultivated in farmlands which account for 7% of the world, wherein the function of fertilizers is unavailable. Chemical fertilizers are important agricultural production data and play an irreplaceable role in agricultural production development, but meanwhile, a plurality of problems are caused by repeated continuous cropping all year round and unreasonable use of chemical fertilizers and pesticides. Due to long-term accumulation and residue of chemical fertilizer components in soil and failure of effective decomposition and nutrition conversion, soil organic matter is reduced, fertilizer and water retention capacity is reduced, and soil fertility is depleted. Meanwhile, various pollutions in soil are induced, such as pesticide residues, fertilizer component residues, various heavy metals and the like, and the ecological system is seriously damaged. The soil lacks a large number of beneficial microorganisms, and the most direct effect is that the root system of the crops grows poorly, which in turn affects the quality and yield of the crops.
Generally, the fertilizer is divided into organic fertilizer, inorganic fertilizer and biological fertilizer. The organic fertilizer is mainly derived from plants and/or animals, and is a carbon-containing material which is applied to soil to provide plant nutrition as a main function. Is prepared from biological substances, animal and plant wastes and plant residues, eliminates toxic and harmful substances in the biological substances, and is rich in a large amount of beneficial substances, including: various organic acids, peptides and rich nutrient elements including nitrogen, phosphorus and potassium. The fertilizer not only can provide comprehensive nutrition for crops, but also has long fertilizer efficiency, can increase and update soil organic matters, promote microbial propagation, improve the physical and chemical properties and biological activity of soil, and is a main nutrient for green food production.
However, because the nutrients of the bio-organic fertilizer are released slowly, the bio-organic fertilizer can not supply nutrients to crops in time when being used alone, so that the yield of the crops is reduced. Therefore, the biological organic fertilizer is generally used together with inorganic fertilizer, but has no obvious promotion effect on the growth and quality of crops.
Disclosure of Invention
In order to overcome the defects of the prior art, one of the purposes of the invention is to provide a fertilizer beneficial to the growth of soil microorganisms, which can increase the propagation of the microorganisms in the soil, reduce soil-borne diseases, increase the air permeability of the soil and improve the fertilizer and water retention capacity of the soil; the invention also aims to provide a preparation method of the fertilizer beneficial to the growth of soil microorganisms, wherein the coating liquid is coated in compound fertilizer particles to form a coating, and when the fertilizer is dissolved in soil, nutrient components can be slowly released into the soil, so that the absorption rate is improved.
One of the purposes of the invention is realized by adopting the following technical scheme:
a fertilizer beneficial to soil microorganism growth comprises the following raw materials in parts by weight: 70-100 parts of organic fermentation product, 5-10 parts of seaweed extract, 20-30 parts of grass carbon, 1-5 parts of humate, 1-5 parts of fatty alcohol-polyoxyethylene ether sodium sulfate, 10-20 parts of hyaluronic acid, 20-30 parts of nitrophosphate fertilizer, 10-20 parts of monopotassium phosphate, 1-3 parts of compound nitrophenol sodium, 5-10 parts of water and 40-50 parts of microbial fertilizer; wherein the microbial fertilizer is at least one of bacillus subtilis, azospirillum brasilense, bacillus mucilaginosus or bacillus amyloliquefaciens.
The fertilizer beneficial to the growth of soil microorganisms uses water-soluble raw materials, seaweed extract, turf, humate, nitrophosphate fertilizer and monopotassium phosphate are used for respectively providing macroelements such as carbon, nitrogen, oxygen, phosphorus, potassium, calcium, magnesium, sulfur and the like for soil, organic fermentation products provide organic matters, and the microbial fertilizer can decompose and release various elements such as potassium, phosphorus, silicon and the like fixed in the soil through self metabolic activity under proper conditions after entering the soil, and is supplied to crops for absorption and utilization. When the sodium fatty alcohol-polyoxyethylene ether sulfate and the hyaluronic acid contact with water in soil, gel can be formed, the soil is promoted to form a good granular structure, and the number of colloids in the soil is increased, so that soil hardening is broken, the soil is loosened, the air permeability of the soil is increased, and the fertilizer and water retention capacity of the soil is improved.
The soil air permeability has obvious influence on the growth of root systems, and also has important influence on the activity of soil microorganisms and the conversion of nutrients. When the soil is lack of oxygen, the released available nutrients are limited, nitrifying bacteria cannot move, and denitrification can be caused to lose nitrogen. Under the anoxic condition, only the anaerobic azotobacter with weak azotobacter activity is activated, while the activities of rhizobia with strong azotobacter and aerobiotic azotobacter are inhibited. Soil aeration can also affect redox conditions. Some nutrient elements in soil, such as nitrogen, sulfur, iron, manganese, phosphorus, etc., are in an oxidized state when the soil is well ventilated, and in a reduced state when the soil is poorly ventilated. If the soil is not aerated well, the reduction state is too strong, and the content of nitrate nitrogen is reduced rapidly. Therefore, the improvement of the soil air permeability is beneficial to the growth and the activity of soil microorganisms.
The azospirillum brasilense is a spiral gram-negative bacterium, is facultative anaerobic, can utilize various carbon sources and nitrogen sources for metabolism, forms conceptual cytomin under the adverse environment, secretes a large amount of polysaccharide, and forms poly B-hydroxybutyrate in vivo as an energy source to overcome the adverse environment. The growth temperature and pH condition range is wide, and the azotobacter has high azotobacter activity under proper conditions, phosphorus dissolving property and the function of promoting the growth of crops.
The bacillus subtilis has more advantages in space site competition, namely, the bacillus subtilis can quickly and massively propagate and fix in the plant body and the soil where the plant grows, so that the propagation of pathogenic microorganisms is effectively prevented, the plant infection of the pathogenic microorganisms of the plant is interfered, the colonization of the pathogenic microorganisms on the plant is damaged, and the effects of inhibiting bacteria and controlling diseases are achieved.
Bacillus mucilaginosus is also called silicate bacteria, and has the important characteristics of decomposing potassium and silicon in minerals such as feldspar, mica and the like, decomposing phosphorus in apatite, and secreting plant growth stimulin and various enzymes to enhance the resistance of crops to certain diseases.
The action mechanism of the bacillus amyloliquefaciens mainly comprises secretion of antibacterial substances, generation of antagonism, competition of nutrition and space, induction of host generation of resistance, promotion of plant growth and the like. The bacillus amyloliquefaciens can generate active substances such as low molecular weight antibiotics, antibacterial proteins or polypeptides and the like, inhibit phytopathogens and can be used as rhizosphere bacteria to promote plant growth. Lipopeptide antibiotics with small molecular weight, good thermal stability, D-amino acid content, protease hydrolysis resistance and organic solvent action are synthesized through a non-ribosome approach, and play a main role in inhibiting plant pathogenic bacteria, fungi, viruses and nematodes in biological control application.
The compound sodium nitrophenolate is a powerful cell activating agent and has the advantages of high efficiency, low toxicity, no residue, wide application range, no side effect, wide use concentration range and the like. After contacting with the plant, the plant can quickly permeate into the plant body, promote the protoplasm flow of the cells and improve the cell activity.
The seaweed extract contains a large amount of non-nitrogenous organic matters, more than 40 mineral elements such as potassium, calcium, magnesium, zinc, iodine and the like and abundant vitamins, particularly contains seaweed polysaccharide, alginic acid, highly unsaturated fatty acid and various natural plant growth regulators which are peculiar to seaweed, and has high biological activity.
Further, the fertilizer beneficial to the growth of soil microorganisms also comprises 1-5 parts of trace elements, wherein the trace elements are at least one of boron, zinc, molybdenum, iron, manganese or copper.
Still further, the organic fermentation product is at least one of animal waste, straws, vinasse, tea leaves or flower residues.
Further, the humate is sodium humate and/or potassium humate.
The second purpose of the invention is realized by adopting the following technical scheme:
the preparation method of the fertilizer beneficial to the growth of soil microorganisms comprises the following steps:
1) mixing and stirring the organic fermentation product, the compound sodium nitrophenolate, the nitrophosphate fertilizer and the monopotassium phosphate to obtain a first mixture;
2) adding humate, seaweed extract and microbial fertilizer into the first mixture, heating and stirring to obtain a second mixture;

5) mixing the compound fertilizer granules screened in the step 4) with the coating liquid obtained in the step 3), and drying to enable the coating liquid to coat the compound fertilizer granules to form a coating, thereby obtaining the fertilizer beneficial to the growth of soil microorganisms.
Specifically, the fatty alcohol-polyoxyethylene ether sodium sulfate, hyaluronic acid and water are prepared into a gelatinous coating solution, water-soluble fertilizer particles are coated, and a coating is formed on the surface after drying. The fertilizer is different from the conventional coated fertilizer, but the coating selected by the invention is soluble, the fatty alcohol-polyoxyethylene ether sodium sulfate and the hyaluronic acid are changed into gel again when contacting with water in soil, and the fertilizer particles in the coating slowly release nutrient components into the soil through the gel, so that the utilization rate of the fertilizer is improved.

Performance testing
The experiment of planting Chinese cabbage in pot is used to verify the influence of fertilizer on crop and microbe. The total number of experimental groups is 7, the fertilizers in examples 1-3 and the fertilizers in comparative examples 1-4 are applied to each group every day in the planting process, and the using amount of the fertilizers in each group is the same. A blank control group was set, i.e. no fertilizer was used during the planting process. Each dish contained 1.5kg of soil (dry weight) from the same source. The sizes and the quantities of the Chinese cabbage seeds sowed in each group of pot plants are all consistent, and the Chinese cabbage seeds are 20. During the planting process, the water content of each pot of the pakchoi is kept at 60 percent by watering. After 68 days, all the pakchoi are ripe (note: 68 days is the time for the last pakchoi to be ripe), harvesting each pakchoi, cleaning, drying and weighing; plant height, stem thickness and leaf width were determined and the data are shown in Table 1. Fresh soil in each plate is collected respectively, the microbial quantity in the soil is measured after screening, the microbial quantity in the soil is measured by adopting a flat plate counting method, the bacteria adopts a beef extract peptone culture medium, the fungi adopts a martin culture medium, the actinomycetes adopts a Gao's I culture medium, and the data are shown in table 2.
TABLE 1 Effect of the fertilizers of examples 1 to 3 and comparative examples 1 to 4 on Brassica rapa
TABLE 2 Effect of fertilizers of examples 1 to 3 and comparative examples 1 to 4 on microorganisms in soil
The effect of fertilizer on the number of soil microorganisms is obviously different by different lower case letters on the same column (P < 0.01)
According to the data in the table 1, the fertilizers of the examples 1 to 3 and the fertilizers of the comparative examples 1 to 4 can improve the yield of the pakchoi, and the fertilizers of the examples 1 to 3 simultaneously comprise a constant fertilizer component, an organic fermentation product and a microbial fertilizer component, so that the plant height, the stem thickness, the leaf width and the yield are better than those of the comparative examples 1 to 4. Among them, example 1 is the most preferable example.
As can be seen from the data in Table 2, the number of microorganisms (bacteria, actinomycetes and fungi) in examples 1 to 3 was higher than that in comparative examples 1 to 4 and the blank control. The microbial quantity arrangement order is as follows: example 1 > example 2 > example 3 > comparative example 1 > comparative example 2 > comparative example 3 > comparative example 4, and the importance of the components affecting the growth of the microorganism can be seen from the above sequence.
Comparative example 4 has no microbial fertilizer and directly reduces the amount of added microbes, so the microbial count of comparative example 4 is the least divided by the blank control.
In the comparative example 3, hyaluronic acid, fatty alcohol-polyoxyethylene ether sodium sulfate and water are not added, namely a layer of coating is not coated outside compound fertilizer particles, the compound fertilizer is directly contacted with soil and the root system of the pakchoi, and because no buffering of gel coating exists, the nutrient components are lost through air evaporation, underground permeation and surface water loss when the crops cannot be absorbed in time; therefore, the yield of crops is low, the soil is poor in looseness and air permeability, moisture and oxygen are difficult to absorb by crops and soil microorganisms, and the propagation speed of the microorganisms is hindered when the microorganisms are in an anoxic and dry state.
In comparative example 2, no organic fermentation product is added, the organic fermentation product provides organic matters for soil, and the lack of the organic matters can cause the loss of carbohydrates (including simple sugars and polysaccharides such as starch, cellulose and hemicellulose), nitrogen-containing compounds (mainly protein) and lignin, thereby influencing the growth and development of crops and the activity of soil microorganisms.
In comparative example 1, no seaweed extract was added, and the seaweed extract contained a large amount of non-nitrogenous organic substances, more than 40 mineral elements such as potassium, calcium, magnesium, zinc, iodine, etc., and abundant vitamins, and particularly contained algal polysaccharides, alginic acid, highly unsaturated fatty acids and various natural plant growth regulators peculiar to seaweeds, and had very high biological activity. Lack of nutrients in seaweed extracts can also have an impact on crop and microbial growth.
In conclusion, the fertilizer which is prepared by the proper component proportion and the preparation method and is beneficial to the growth of soil microorganisms can effectively promote the growth of microorganisms, can comprehensively supplement macro-elements and trace elements required by the whole growth of crops, improve the nutrient absorption and utilization capacity of the crops and stimulate the growth of the crops.
