Description
Technical Field
The invention relates to the technical field of soil improvement, in particular to a composition for improving farmland soil nutrients and a preparation method thereof.
Background
The soil improvement is to adopt corresponding measures to improve the soil property and improve the soil fertility aiming at the bad texture and structure of the soil, and the soil improvement repairing agent is an important application of the soil improvement. With unreasonable application of chemical fertilizers, particularly phosphate fertilizers, and insufficient application of organic fertilizers, on one hand, the problems of soil salinity increase, acidification, salinization, hardening and the like are caused; on the other hand, calcium, magnesium, iron, zinc, etc. in the soil are fixed by phosphorus and lose activity. The condition of soil moisture and nutrient is the key to directly influence the growth of plants.
The existing soil conditioner basically depends on external organisms and organic components as nutrient substances for crop growth, improves crop growth and development, increases yield, ignores the release and utilization of nutrient elements of soil, and cannot activate the nutrition of the soil to realize real weight reduction and synergism.
In conclusion, how to provide a conditioner for activating the release of nutrient elements in soil is a problem that needs to be solved by those skilled in the art.
Disclosure of Invention
In view of the above, the invention provides a composition for improving farmland soil nutrients and a preparation method thereof. The composition can effectively improve the content of absorbable nitrogen and phosphorus in the soil and can improve the yield of crops planted in the soil.
In order to achieve the purpose, the invention adopts the following technical scheme:
the composition for improving the nutrient content of farmland soil comprises the following components in parts by weight: 48-55 parts of wormcast, 37-53 parts of grapefruit slag, 33-45 parts of shell powder, 25-40 parts of gamma-polyglutamic acid, 28-50 parts of biomass charcoal, 18-36 parts of urease inhibitor and 6-15 parts of microbial agent.
The beneficial effects are as follows:
the grapefruit slag and the microbial agent are compounded for use, the grapefruit slag contains rich fiber matrixes, has strong water absorption capacity, can absorb water to provide a high-humidity environment and a carbon source, and provides a nitrogen source for azotobacter; the microorganisms can rapidly grow and propagate under the system, so that the degradation of organic matters is accelerated to be converted into various nutrient substances, more nutrients such as N, P, K and the like are released, the soil fertility is increased, the growth of the microorganisms can be promoted while the soil environment is improved, a virtuous circle is formed, and the soil improvement is promoted; the life activities of the compound microbial flora in the soil can loosen the soil, obviously improve the soil hardening and increase the air permeability of the soil; on the other hand, the growth metabolic process can provide various organic nutrients such as natural organic acid, amino acid, vitamin, auxin and the like, promote the growth of plants and improve the disease resistance of the plants.
The wormcast is a black, uniform and fine-grained substance with natural earthy taste, and has good porosity, air permeability, water drainage and high water holding capacity. The fine particles also help to increase the contact of the soil with the air as much as possible, since they do not harden and harden the soil when mixed with the soil. The wormcast has a large surface area, so that a plurality of beneficial microorganisms can live, and the wormcast has the capacity of absorbing and maintaining nutrient substances. The wormcast is rich in bacteria, actinomycetes and fungi, and the microorganisms not only mineralize complex substances into effective substances which are easy to be absorbed by plants, but also synthesize a series of substances with biological activity, such as sugar, amino acid, vitamins and the like.
The shell powder is a powder processed by crushing shells of oyster, freshwater mussel, clam, snail and the like after meat removal. Belongs to mineral supplement. The shell powder is powder prepared by crushing and grinding shells, and 95 percent of the components of the shell powder are calcium carbonate, chitin and a small amount of amino acid and polysaccharide substances.
The gamma-polyglutamic acid is anionic polyamino acid generated by microbial fermentation in nature, a large number of free side chain hydroxyl groups with extremely high activity are arranged on a molecular chain, hydrogen bonds can be formed in molecules or among the molecules, the water solubility is good, the water retention is strong, certain complexing capacity is realized, and the gamma-polyglutamic acid has a good application prospect in the aspect of fertilizer synergism by being matched with modification of phosphate rock powder.
The porous structure of the biomass charcoal can adsorb nutrient substances to increase the storage capacity of soil nutrient and water, and the soil structure improvement and soil nitrogen fixation are realized.
The urease inhibitor can inhibit the activity of soil urease within a period of time, so that the hydrolysis of nitrogen fertilizer is slowed down, and the volatilization and nitrification of ammonium nitrogen are reduced.
Preferably, the composition for improving the farmland soil nutrient comprises the following components in parts by weight: 48-52 parts of wormcast, 40-53 parts of grapefruit slag, 38-45 parts of shell powder, 25-32 parts of gamma-polyglutamic acid, 32-46 parts of biomass charcoal, 22-31 parts of urease inhibitor and 8-12 parts of microbial agent.
Preferably, the composition for improving the farmland soil nutrient comprises the following components in parts by weight: 50 parts of wormcast, 46 parts of grapefruit residues, 42 parts of shell powder, 27 parts of gamma-polyglutamic acid, 40 parts of biomass charcoal, 25 parts of urease inhibitor and 8 parts of microbial agent.
Preferably, the biomass charcoal is produced by carbonizing coconut shells at 500-800 ℃ under an anoxic condition.
Preferably, the grapefruit slag is a byproduct of juicing grapefruit peel or grapefruit pulp.
Preferably, the urease inhibitor is any one of phenyl phosphorodiamidate, thiophosphoric triamide, phosphoric triamide or ammonium thiosulfate.
Preferably, the microbial agent is a mixture of bacillus subtilis, bacillus megaterium, bacillus mucilaginosus and azotobacter vinelandii.
Preferably, the mass ratio of the bacillus subtilis to the bacillus megaterium to the azotobacter vinelandii is 1:1:1: 1.
A preparation method of a composition for improving farmland soil nutrients is characterized by comprising the following steps:
(3) drying and crushing wormcast and grapefruit slag, weighing according to the mass, and uniformly mixing for later use;
(4) weighing shell powder, gamma-polyglutamic acid, biomass charcoal and a urease inhibitor according to the mass, and uniformly mixing for later use;
(3) and (3) uniformly mixing the substances obtained in the step (1) and the step (2) with a microbial agent to obtain the composition.
According to the technical scheme, compared with the prior art, the invention has the following beneficial effects: (1) the components are synergistic, so that the content of absorbable nitrogen and phosphorus in the soil is increased; (2) organic matters in the soil are increased, germs in the soil are inhibited, and the self-repairing capability of the soil is improved; (3) the formula is simple, the soil activating agent does not contain heavy metals, antibiotics and the like, the release of nutrient elements of the soil is activated, potential risks do not exist, and the soil activating agent is safe to the ecological environment.

The control group was not treated. Then, the peanuts are sowed, and the soil nutrient content and the peanut growth condition are measured after 2 months.
(2) Measurement items: nitrate nitrogen, available phosphorus, quick-acting potassium, organic matters and peanut yield.
(3) The determination method comprises the following steps: and (3) measuring the content of the soil nutrients by adopting a TPY-8A soil nutrient tacheometer.
(4) As a result: the results are shown in Table 1.
TABLE 1 soil nutrient content and peanut growth
| Measurement items | Experimental group | Control group |
| Nitrate nitrogen (mg/kg) | 25.38 | 3.95 |
| Available phosphorus (mg/kg) | 13.22 | 26.54 |
| Quick-acting potassium (mg/kg) | 98.65 | 180.32 |
| Organic matter (g/kg) | 0.56 | 0.35 |
