Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to a polystyrene soil loosening and root promoting agent, its preparation method and application. Background Technology

[0002] Existing chemical fertilizers, such as urea, while highly fertilizing, can cause root burn in some plants due to their shallow, thick, and fragile root systems. Furthermore, long-term use of chemical fertilizers can lead to soil compaction, hindering crop growth and disrupting the ecological balance of the land. Topdressing can also cause crops to grow too quickly, resulting in low fertilizer utilization and reduced fruit quality.

[0003] Existing technologies include various synergists to improve the utilization rate of chemical fertilizers, which have some positive effects on promoting root growth and thus increasing grain yield. However, existing fertilizer utilization improvement formulations still have shortcomings. Current synergists generally use indolebutyric acid and naphthaleneacetic acid as active ingredients, which are often single-function and simple in composition, failing to fully meet the needs of healthy crop root growth. In particular, they have a limited effect on improving the physiological characteristics of crop growth, and can also cause problems such as soil compaction due to chemical fertilizers.

[0004] Therefore, how to provide a fertilizer synergist that can effectively promote crop growth and inhibit soil compaction is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a polytetracycline soil loosening and root promoting agent, its preparation method and application, to solve the technical problem of soil compaction caused by the application of chemical fertilizers and fertilizer synergists in the prior art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] This invention provides a polyaspartic acid soil loosening and root promoting agent, which is prepared from the following components in parts by weight: 10-20 parts of polyaspartic acid, 5-10 parts of γ-polyglutamic acid, 6-10 parts of organic acid, 8-10 parts of sodium carboxymethyl cellulose, 1.5-2.0 parts of fatty alcohol polyoxyethylene ether, 2-4 parts of indoleacetic acid, 4-6 parts of sodium humate, 0.5-1.0 parts of mineral-derived potassium humate, 2-3 parts of potassium dihydrogen phosphate, 14-18 parts of trace elements, 4-6 parts of attapulgite, and 4-6 parts of bentonite.

[0008] Preferably, the trace elements include ferrous sulfate, zinc sulfate, copper sulfate, manganese sulfate, boric acid, and magnesium sulfate heptahydrate.

[0009] Preferably, the mass ratio of ferrous sulfate, zinc sulfate, copper sulfate, manganese sulfate, boric acid, and magnesium sulfate heptahydrate is 30-40:8-12:4-8:5-9:3-7:20-30.

[0010] Preferably, the organic acid includes succinic acid and fumaric acid.

[0011] Preferably, the mass ratio of succinic acid to fumaric acid is 1-3:4-6.

[0012] This invention also provides a method for preparing the aforementioned polyasphaltene soil loosening and root promoting agent, comprising the following steps:

[0013] (1) Mix and grind the attapulgite and bentonite to obtain material 1;

[0014] (2) Mix material 1, polyaspartic acid, γ-polyglutamic acid, organic acid, sodium carboxymethyl cellulose, fatty alcohol polyoxyethylene ether, indoleacetic acid, sodium humate, mineral potassium humate, potassium dihydrogen phosphate and trace elements to obtain polyaspartic acid soil loosening and root promoting agent.

[0015] Preferably, the ground material 1 is passed through a 200-260 mesh sieve, and the material passing through the sieve is material 1.

[0016] This invention also provides a polytetracycline soil loosening and root promoting agent, and the application of the polytetracycline soil loosening and root promoting agent prepared by the preparation method described above in crop planting.

[0017] Preferably, the polytetracycline soil loosening and root promoting agent is mixed with base fertilizer and applied before crop planting; the application rate of the polytetracycline soil loosening and root promoting agent is 1.5-2.5 kg / mu.

[0018] Preferably, the crop is corn.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Existing synergists only have a simple growth-promoting effect, similar to traditional chemical fertilizers. They only consider the addition of external nutrients, applying the nutrient components directly to the field. However, the absorption of nutrients still depends on the crop itself. If the proportion of certain nutrients added is inappropriate, it may even have an inhibitory effect. The polyenzyme soil loosening and root-promoting agent provided by this invention takes into account the crop's own nutrient synthesis. By adding organic acids, it enhances the crop's own metabolic processes, thereby promoting crop growth.

[0021] 2. The organic acids added in this invention can enhance the plant's ability to synthesize nutrients. They are small-molecule organic acids and are intermediate metabolites of the TCA cycle. By artificially supplementing organic acids from external sources, the entire TCA cycle process can be activated and accelerated, providing efficient energy for crops.

[0022] 3. The polyaspartic acid added in this invention is a fertilizer synergist. It has a chelating effect on metal ions and can enrich nitrogen, phosphorus, potassium, and trace elements for supply to plants, enabling crops to utilize fertilizers more effectively and increasing crop yields. γ-Polyglutamic acid can efficiently improve the dissolution, storage, transport, and absorption of fertilizers, preventing sulfate, phosphate, and oxalate ions from precipitating with metal elements, allowing crops to more effectively absorb phosphorus, magnesium, and trace elements from the soil, and promoting crop root development.

[0023] 4. Sodium carboxymethyl cellulose readily disperses in water to form a transparent colloidal solution, which helps retain moisture and facilitates the function of other components. In particular, it helps γ-polyglutamic acid form a thin film on the surface of plant root hairs, thus protecting the roots of crops.

[0024] 5. Attapulgite and bentonite are ground into ultrafine particles, which can slow down water seepage in the upper part of the soil. On the other hand, as an ultrafine powder, it can make full use of its large specific surface area after being wetted by water and has good physical adhesion. It can block the seepage channels of the lower compacted soil to reduce water seepage, and can also effectively increase soil porosity, improve soil compaction, and play a role in soil improvement.

[0025] 6. Among the components added in this invention, indoleacetic acid, as a cell activator, can rapidly penetrate into the plant after contact, promoting protoplasmic streaming and enhancing cell vitality. Fatty alcohol polyoxyethylene ether can enhance soil aeration and water / fertilizer permeability, thereby loosening the soil. Humic acid and potassium dihydrogen phosphate have a significant effect on reducing nitrogen fertilizer loss; therefore, this invention uses the root-promoting agent mixed with base fertilizer to improve fertilizer utilization efficiency for crops while promoting root development and loosening the soil. Due to its strong complexing ability, mineral-derived potassium humate, when used in conjunction with trace elements, can effectively promote the absorption and utilization of trace elements by plant roots.

[0026] 7. The polyenzyme soil loosening and root promoting agent provided by this invention can effectively promote crop growth, eliminate soil compaction, enhance soil permeability, restore porous aggregate structure, reduce soil bulk density, loosen the soil in the root layer of crops, promote the increase and penetration of plant roots, and increase crop yield, with significant effects.

[0061] Experimental Example 1

[0062] Comparative experiment: A planting area was selected and corn of the variety Xianyu 335 was planted. The experimental land was divided into 27 plots. Each experimental group was randomly planted in three plots. Except for the application of soil loosening and root-promoting agent, the other growth management methods were exactly the same.

[0063] The product obtained by the method in Example 3 was used as the experimental group.

[0064] Based on the growth-promoting effect of organic acids, this experiment studied the influence of organic acid variables on plant growth, and set up control groups 1 to 3 as follows.

[0065] Control group 1: The other methods were the same as in Example 3, except that no organic acid was added;

[0066] Control group 2: The other methods were the same as in Example 3, except that succinic acid was not added;

[0067] Control group 3: The other methods are the same as in Example 3, except that succinic acid is replaced with an equal amount of malic acid;

[0068] This experiment also investigated whether attapulgite and bentonite, as agents for improving soil compaction, would affect the effectiveness of soil loosening and root-promoting agents. The following control group (4-5) was set up.

[0069] Control group 4: The other methods were the same as in Example 3, except that no attapulgite or bentonite was added;

[0070] Control group 5: Other methods were the same as in Example 3, except that attapulgite and bentonite were added directly as components without grinding;

[0072] Control group 6: The other methods were the same as in Example 3, except that γ-polyglutamic acid was not added;

[0073] Control group 7: The other methods were the same as in Example 3, except that no trace elements were added;

[0074] It is also compared with existing products: Hai Zhi Yuan Bao Gen (Zhengzhou Hai Zhi Yuan Biotechnology Co., Ltd.).

[0075] The application method for the experimental group and control groups 1 to 7 was as follows: before corn planting, the obtained product was mixed with base fertilizer and applied, followed by immediate watering after corn planting; the application rate of the product was 2 kg / mu. The application method for the existing technology group was as per the instruction manual.

[0076] During the grain-filling stage of corn, soil samples were taken at a depth of 5–10 cm, and the soil bulk density was determined using a five-point sampling method. After corn harvest, the yield and shelling rate of corn in each experimental group were measured, and the results are shown in Tables 1 and 2.

[0082] As shown in Tables 1 and 2, the polyenzyme-based soil loosening and root-promoting agent of this invention can significantly promote crop growth and increase crop yield, with a significantly better effect than existing products. Existing products have limited functionality; although corn yield and seed production are not significantly different from those of this invention, the soil bulk density of the existing product group differs significantly from that of the experimental group. This demonstrates that the product obtained by this invention has the dual effects of promoting growth and loosening soil.

[0083] The data from the control group show that the effects of attapulgite and bentonite become apparent after field planting, significantly impacting maize growth and reducing soil bulk density. The types of trace elements and organic acids also significantly affect maize yield and soil bulk density data.
