Description

Technical Field

[0001] This invention belongs to the field of fertilizer experimentation, specifically a field experiment method for fertilizer testing. Background Technology

[0002] To explore the effects of fertilizers on crop nutrient absorption, yield increase, quality improvement, fertilizer utilization rate, and soil fertility under field conditions, and to better guide fertilization, fertilizer field trials play a crucial role in agricultural research. However, existing experimental methods often result in large discrepancies between replicates and poor data accuracy. For example, nitrogen fertilizer utilization rate remains controversial in academia. Reports on nitrogen fertilizer utilization rates in grain crops range from around 30% to over 50%, a significant difference. High-quality journals typically require data from multiple locations and over several years for publication, indirectly demonstrating the unreliability of field trial data. Despite these numerous problems and the long duration of field trials, no scientifically sound method has yet been proposed, indicating that finding a more scientific approach to field trials is not an easy task.

[0003] Chinese Patent Publication No. CN 114600660 B discloses a field trial method for fertilizer testing. The method involves rotary tilling and pulverizing the soil at appropriate moisture levels, dividing the soil into experimental plots, and establishing micro-zones within each plot. The topsoil from these micro-zones is removed, and the micro-zones are separated by PVC boards or plastic film. The removed soil is immediately pulverized, mixed, and then quantitatively and evenly distributed back into the micro-zones. Field trials are conducted according to standard fertilizer testing procedures. Finally, the crops and soil within the micro-zones are used as the research subjects to obtain the necessary data. This method ensures that soil fertility is uniform and consistent across all micro-zones, containing the same amount of nutrients, thus representing the fertility level of the tested soil. This significantly improves the accuracy and precision of data obtained from field trials and enhances the efficiency of soil and fertilizer scientific research.

[0004] This method provides a reliable and convenient new field trial approach, resulting in high accuracy and precision in obtaining experimental data, thereby improving the quality of field trials and saving unnecessary manpower, material resources, and financial resources in scientific research. However, this method involves multiple operations, such as rotary tillage, soil sampling, crushing, and mixing, requiring considerable manual labor. Human intervention may introduce errors, affecting the accuracy of the experiment. Furthermore, while isolating the experimental micro-plots with PVC boards or plastic films can reduce the influence of the external environment, it may not completely eliminate it. For example, factors such as precipitation, temperature, and sunlight may affect the experimental results. Therefore, this proposal suggests a field trial method for fertilizer experiments, conducting experiments on fertilizers in field soils to explore the effects of fertilizers on soil fertility under different precipitation and soil permeability conditions, providing reference information for soil improvement and sustainable agricultural development. Summary of the Invention

[0005] To address the issue of how precipitation factors can affect experimental results, this invention provides a field test method for fertilizer experiments to explore the impact of fertilizers on soil fertility under different precipitation and soil permeability conditions, providing reference information for soil improvement and sustainable agricultural development.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a field trial method for fertilizer testing, comprising the following steps:

[0007] Step 1, Preparation and seepage prevention: Dig pits in the field soil and take measures to prevent seepage.

[0008] Step 2, setting up isolation zones and bedding layers: A support frame is installed over the pit, and partitions are installed to prepare the first and second isolation zones. First and second bedding layers are laid at the bottom of the first and second isolation zones, with different permeability. Baffles are fixed within the first and second isolation zones to prepare the third and fourth isolation zones respectively. Equal amounts of soil are evenly spread within the third and fourth isolation zones.

[0009] Step 3, installation of water pipes and solenoid valves: Fix the water pipes on the bracket, connect the auxiliary pipes to the water pipes on one side of the third and fourth isolation zones, and connect the solenoid valves to the auxiliary pipes; connect the connecting pipes to the water pipes, fix the end of the connecting pipes away from the water pipes to the bottom of the pit, and connect the water pump and water purification equipment to the connecting pipes;

[0010] Step 4: Conduct experiments with different watering amounts: Water the first and second isolation zones according to the preset watering time. The watering amount for the third isolation zone in the first isolation zone is different, and the watering amount for the fourth isolation zone in the second isolation zone is different.

[0011] Step 5, Soil fertility testing and recording: Test the soil fertility in the field according to the preset testing time and record the results.

[0012] The principle and beneficial effects of the above scheme are as follows: 1. Taking measures to prevent seepage can prevent water leakage or loss, and at the same time ensure the accuracy and reliability of the test results to a certain extent.

[0013] 2. By setting up supports and installing partitions, the experimental area was divided into a first isolation zone and a second isolation zone to achieve fertilizer experiments under different conditions. Layers with different permeability were laid at the bottom of the first and second isolation zones to simulate different soil permeability. By fixing baffles, the first and second isolation zones were further divided into a third and a fourth isolation zone, preparing for experiments with different watering amounts. An equal amount of soil was evenly spread in each isolation zone to provide a consistent soil environment for subsequent fertilizer application.

[0014] 3. Secure the water pipes to the bracket and connect them to one side of the third and second isolation zones. Connect auxiliary pipes and solenoid valves to control the watering volume in different isolation zones.

[0015] 4. Water the first and second isolation zones according to the preset schedule. The amount of water given to the first isolation zone, the third isolation zone, and the fourth isolation zone within the second isolation zone will differ. This will help to observe the impact of different watering amounts on soil fertility.

[0016] 5. At predetermined time points, test soil fertility in the field. This may include measuring parameters such as soil nutrient content, pH value, and microbial activity. Record the test results to analyze the effects of fertilizer trials under different conditions.

[0017] 6. Connecting the water pipe to the bottom of the pit via a connecting pipe allows for the purification and reuse of water seeping down from the support, minimizing water usage in the test area and thus conserving water resources during the test.

[0018] 7. This study investigates the impact of fertilizers on soil fertility by simulating different soil permeability conditions and irrigation amounts. By controlling water supply, the absorption and effects of fertilizers in different soil environments are observed, revealing the mechanism of fertilizer action under varying soil conditions. The use of isolation zones and subgrades with different permeability levels allows for control of experimental conditions, reducing external interference and ensuring more reliable results. Measuring soil fertility parameters provides a quantitative assessment of fertilizer effects on the soil, offering scientific data support. This method simulates different soil permeability and irrigation amounts, more closely resembling actual field environments and better guiding agricultural production practices. This contributes to understanding the effects of fertilizers under different soil conditions, providing a scientific basis for optimizing fertilizer application strategies, increasing crop yields, and protecting the environment. Furthermore, exploring the impact of fertilizers on soil fertility provides important reference information for soil improvement and sustainable agricultural development.

[0019] Furthermore, in step one, the area selected for digging the pit is a flat area; an impermeable membrane is laid at the bottom and around the pit to prevent seepage.

[0020] Beneficial effects: Geomembranes effectively prevent water seepage, helping to control the moisture content of the test area, ensuring uniform and consistent soil moisture distribution during the experiment, and facilitating accurate comparisons of effects under different test conditions. They also prevent water from seeping from the test area into the surrounding soil, thus maintaining a stable moisture state within the test area. Furthermore, geomembranes prevent external water from entering the test area, reducing interference from factors such as rainfall and contributing to the stability of the test environment. Simultaneously, they reduce the risk of pollution to the surrounding environment, protecting the ecological environment.

[0021] Furthermore, in step three, a shower head is connected to the auxiliary pipe.

[0022] Beneficial effects: A showerhead can evenly spray water onto the test area, ensuring uniform moisture distribution throughout. This helps maintain consistency and comparability in the experiment, as well as accurately assess the effects under different conditions. The spraying effect of a showerhead is similar to natural rainfall, making the test conditions closer to the actual growing environment and helping to more accurately simulate plant growth under real natural conditions.

[0023] Furthermore, in step four, the same crop can be planted in the soil before watering, and watering can be carried out according to the growth stage of the crop.

[0024] Beneficial effects: Planting the same crop within the experimental area and irrigating it according to its growth stage allows for a more realistic simulation of the actual farmland environment. This yields more accurate and comparable experimental results, helping to understand the impact of different irrigation amounts on crop growth. Different crops may differ in growth rate, physiological characteristics, etc., but selecting the same crop for the experiment can eliminate these differences and better assess the impact of irrigation amount on crops.

[0025] Furthermore, in step five, the preset testing time is once every two days.

[0026] Beneficial effects: Testing every two days allows for thorough observation of the dynamic changes in plant growth and soil fertility. Frequent testing captures short-term trends and effects, providing more accurate data. By testing every two days, if poor plant growth or soil fertility issues are detected, adjustments and corrections can be made promptly to ensure the accuracy and effectiveness of the experiment.

[0027] Furthermore, in step five, soil fertility testing includes testing nutrient content, soil pH, organic matter content, trace element content, electrical conductivity, soil moisture content, and microbial activity.

[0028] Beneficial Effects: By detecting multiple indicators such as nutrient content, soil pH, organic matter content, trace element content, electrical conductivity, soil moisture content, and microbial activity, soil fertility can be comprehensively assessed. These indicators comprehensively reflect key factors such as soil nutrient supply, soil pH characteristics, soil organic matter and trace element content, salinity, soil moisture, and microbial activity. The detection of these indicators can reveal potential problems in the soil, such as nutrient deficiency or excess, abnormal pH, insufficient organic matter, trace element deficiency, and salinization, and provide data to support corresponding adjustments and remedial measures to improve soil fertility.

[0029] Furthermore, the water purification equipment includes a water filter box, with an inlet and an outlet at each end. Several first plates and second plates are fixedly connected inside the water filter box, and the first plates and second plates are fixedly connected to both sides of the water filter box, with the first plates and second plates arranged alternately. Several filter layers are fixedly connected between the first plates and second plates.

[0030] Beneficial effects: Multiple filtration layers within the filter tank effectively remove suspended solids, sediment, particulate matter, bacteria, viruses, and other impurities from the water. This provides clean, clear water, ensuring the safety of drinking water. The first and second plates within the filter tank are staggered, forming a multi-layered filtration structure. This design increases the path of water flow through the filtration layers, allowing for more thorough contact and filtration of the water as it passes through the filter media, thus improving the removal of impurities.

[0031] Furthermore, the filter layers sequentially include a coarse filter layer, a sand filter layer, an activated carbon layer, a ceramic filter layer, and a fine filter layer.

[0032] Beneficial Effects: The coarse filter layer, typically composed of coarse sand, quartz sand, and other materials, effectively removes large particles, suspended solids, and silt from the water. It prevents these larger particles from clogging subsequent filter media, protecting the normal operation of the entire filtration system. The sand filter layer further removes fine particles, colloidal substances, and organic matter from the water. Through the gaps between different particles within the sand layer and surface adsorption, water comes into contact with and is filtered by the sand particles during the filtration process, improving the water purification effect. The filter layers sequentially include a coarse filter layer, a sand filter layer, an activated carbon layer, a ceramic filter layer, and a fine filter layer. Each filter layer plays a specific filtration role, working together to achieve multiple purifications of the water. This design structure gives the water purification equipment advantages such as high-efficiency filtration, removal of multiple contaminants, protection of subsequent filter media, and provision of safe and reliable drinking water.

[0037] Example 1

[0038] The basic implementation examples are as follows: Figure 1 and attached Figure 2 As shown:

[0039] A field trial method for fertilizer testing includes the following steps:

[0040] Step 1, preparation and seepage prevention: Select a flat location, dig a pit in the soil in the field, and lay a seepage-proof membrane at the bottom and around the pit for seepage prevention.

[0041] Step two, setting up isolation zones and bedding layers: A support 2 is installed over the pit, and a partition 3 is mounted and fixedly connected to the support 2 to prepare a first isolation zone 4 and a second isolation zone 5. A first bedding layer and a second bedding layer are laid at the bottom of the first isolation zone 4 and the second isolation zone 5, respectively. The first bedding layer and the second bedding layer have different permeabilities. Therefore, the first isolation zone 4 and the second isolation zone 5 serve as a control group.

[0042] The third isolation zone 8 and the fourth isolation zone 9 are prepared by fixing baffles in the first isolation zone 4 and the second isolation zone 5, respectively; equal amounts of soil are evenly spread in the third isolation zone 8 and the fourth isolation zone 9. The area between the third isolation zones 8 and the area between the fourth isolation zones 9 serve as the control group.

[0043] Step 3, installation of water pipe 1 and solenoid valve: Water pipe 1 is fixed on bracket 2. Auxiliary pipe 11 is connected to water pipe 1 on one side of the third isolation zone 8 and the fourth isolation zone 9. Solenoid valve is connected to auxiliary pipe 11. Connecting pipe 13 is connected to water pipe 1. The end of connecting pipe 13 away from water pipe 1 is fixed to the bottom of the pit. Water pump 14 and water purification equipment 15 are connected to connecting pipe 13. Shower head 16 is connected to auxiliary pipe 11.

[0044] Step four, conduct experiments with different watering amounts: Water the first isolation zone 4 and the second isolation zone 5 every two days. Before watering, the same crop, such as wheat, can be planted in the soil, and watering should be carried out according to the crop's growth stage. The watering amount for the third isolation zone 8 in the first isolation zone 4 is different, and the watering amount for the fourth isolation zone 9 in the second isolation zone 5 is different.

[0045] Step 5, Soil fertility testing and recording: Conduct field soil fertility testing according to the preset testing time and record the results. Soil fertility testing includes testing nutrient content, soil pH, organic matter content, trace element content, electrical conductivity, soil moisture content, and microbial activity.

[0046] Example 2

[0047] The difference between this embodiment and the above embodiment is that: the water purification device 15 includes a water filter tank, with an inlet and an outlet at both ends of the water filter tank. Several first plates and second plates are fixedly connected inside the water filter tank, respectively, and are staggered on both sides of the water filter tank. Several filter layers are fixedly connected between the first plates and the second plates. The filter layers sequentially include a coarse filter layer, a sand filter layer, an activated carbon layer, a ceramic filter layer, and a fine filter layer.

[0048] The specific implementation process is as follows: One end of the connecting pipe 13 is connected to the water pipe 1, and the other end of the connecting pipe 13 is fixed to the bottom of the pit. Water that has permeated through the first and second bedding layers falls into the pit. The water pump 14 draws the water from the pit into the filter tank for filtration and then delivers it to the water pipe 1. The water enters the filter tank from the inlet and passes through the tortuous path formed by the first and second plates, where it is filtered by the filter layers.
