[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a sampling and fertilizing component on the inner side of a fixed fertilizing cylinder. The feed motor cooperates with the sampling cylinder to drive the spiral sampling cylinder to go deep into the soil to sample the soil. After the sampling is completed, the collected soil is automatically turned over and poured into the soil feeding cylinder. The sampled soil falls into the soil testing trough through the soil feeding cylinder and the soil screening cylinder in turn.

[0019] 2. The present invention installs a soil screening cylinder on the inner side of the fertilization frame. Two groups of screening mesh plates in the soil screening cylinder screen out impurities in the sampled soil. The screened soil falls to the bottom inner side of the soil screening cylinder and is mixed evenly to prepare a test sample. Impurities in the sampled sample are removed to reduce the influence of impurities on the test results, so as to ensure the quality of the soil sample and the accuracy of the test, so that the highly intelligent soil testing and fertilization instrument can more accurately determine the content of various nutrients and physical and chemical indicators in the soil, and provide accurate data support for scientific fertilization.

Accurately controlling the supply of fertilizers can reduce unnecessary fertilizer inputs, thereby reducing agricultural production costs, reducing fertilizer loss and residues, and reducing adverse effects on the environment. The fertilizer supply plan can be flexibly adjusted according to the needs of different soil types, crop types and growth stages.

[0021] 4. The present invention provides a soil scraping component on the inner side of a fixed fertilizing cylinder.

Scraping the soil can prevent the fertilizer from being lost due to rain erosion or wind erosion, and reduce nutrient loss. After the soil is scraped, the structure of the soil surface is improved, which is conducive to soil ventilation and water retention, helps to maintain the activity of microorganisms in the soil, promotes the decomposition of organic matter and the circulation of nutrients, and provides a better growth environment for crops.

After the fertilizer falls into the sampling soil pit, the secondary sampling soil falls to cover and bury the fertilizer. A part of the sampled soil can also be used for nutrient detection, and the other part is retained in the spiral sampling tube 32 for burying fertilizer. After fertilization, the scraping cylinder 23 works to push the external ring 24 to pass through the arc opening 19 and move to the inside of the fixed fertilization tube 2. The two sets of soil scrapers 25 are docked after work, and the protrusions 27 are inserted into the docking grooves 28. The soil scrapers 25 scrape the soil to ensure uniform distribution of fertilizers, avoid fertilizer accumulation or excessive concentration, and are conducive to uniform distribution of fertilizers in the soil layer so that the soil absorbs nutrients evenly, avoid fertilizer concentration or loss, and thus improve the utilization rate of fertilizers. Scraping the soil can prevent fertilizer from being lost due to rain erosion or wind erosion, and reduce nutrient loss. After the soil is scraped and leveled, the structure of the soil surface is improved, which is beneficial to soil ventilation and water retention, helps maintain the activity of microorganisms in the soil, promotes the decomposition of organic matter and the circulation of nutrients. The uniform distribution of fertilizer means that plant roots can better absorb nutrients, thereby promoting the healthy growth of plants. Burying the fertilizer in the soil and then scraping it can reduce the environmental pollution caused by the fertilizer exposed on the soil surface. Exposed fertilizer is easily carried away by wind or rain, and enters the water or air to pollute the environment. The fixed roller frame 13 provides an installation position for the leveling roller 14. After the soil is leveled, the leveling roller 14 further levels and compacts the excavated soil.

[0033] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 , a fertilization device with soil sampling function for agricultural use; It includes a soil scraper 25, an annular flow channel 29 and a drip port 30. A soil scraping assembly is arranged on the inner side of the fixed fertilizer cylinder 2. A drip port 30 is provided at the bottom of the soil scraper 25, and the drip port 30 is communicated with the annular flow channel 29. A water inlet pipe 26 is installed on the top of the soil scraper 25, and the water inlet pipe 26 is communicated with the annular flow channel 29. A water supply device 12 is installed on the top of the fertilizer rack 1, and the output end of the water supply device 12 is connected to the water inlet pipe 26 through a pipeline. After the soil scraper 25 scrapes the soil flat, the water supply device 12 works to supply water to the soil scraper 25 through the pipeline. The water enters the soil scraper 25 through the water inlet pipe 26, moves along the annular flow channel 29, and is discharged from the drip port 30 to water the soil, which is conducive to the uniform distribution and flow of water in the soil, helps to ensure that crops get enough water, and prevents problems such as root rot caused by water accumulation. Watering after fertilization can penetrate the fertilizer into the deep soil layer, so that the root system can better absorb nutrients, improve the nutrient utilization rate of plants, and water can help the microorganisms in the fertilizer to absorb nutrients. The elements are quickly transported to the plant body to meet the crop's needs for these fertilizer elements. If water is not applied in time after fertilizer application, the sun will cause the nutrients in the fertilizer to evaporate and be lost. Reasonable watering can control the release rate of fertilizer and reduce loss, thereby increasing the fertilization effect. Deep application of chemical fertilizers plus watering can make the fertilizer stay in the soil longer, the fertilizer effect time is also longer, the fertilizer effect is more lasting, the nutrients can be more evenly distributed in the soil, crops absorb more fully, help the soil moist and soft, which is beneficial to the growth and development of the root system.

[0034] The method for using the fertilizing device comprises the following steps: Step S1, first the feed motor 31 operates and cooperates with the sampling cylinder 22 to drive the spiral sampling cylinder 32 to go deep into the soil to sample the soil. After the sampling is completed, the horizontal slide 40 moves to the bottom of the spiral sampling cylinder 32, and the soil is fed into the automatic turning box 41, and the spiral sampling cylinder 32 collects the soil again; Step S2, the two groups of screening mesh plates 43 in the soil screening cylinder 6 screen out impurities in the sampled soil, and the screened soil falls to the inner side of the bottom of the soil screening cylinder 6, and the mixing motor 48 drives the soil mixing frame 49 to rotate to mix the soil evenly to prepare a test sample; Step S3, the fertilizer supply box 8 adds various fertilizers according to the fertilizer application amount, the mixing motor 59 drives the mixing rack 60 to mix the added fertilizers, and the mixed fertilizers fall from the fertilizer pipe 62 into the sampling soil pit, the secondary collected soil falls and covers the fertilizer, and the soil leveling component leveles the soil.

The spiral sampling cylinder 32 collects the soil again, and the sampling transfer cylinder 5 contracts to drive the horizontal slide frame 35 to move up. The automatic turning box 41 works to pour the sampled soil into the soil feeding cylinder 7.
