[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Soil-borne diseases of tobacco in my country refer to a general term for diseases caused by pathogens that survive in or on the soil surface, infecting tobacco plants both in the soil and above ground. These diseases are prevalent in all major tobacco-producing areas of my country, and in some areas, they can even cause devastating damage, seriously threatening the sustainable and healthy development of tobacco production. There are many types of pathogens causing tobacco soil-borne diseases, the most common being *Ralstonia solanacearum*, *Phytophthora parasitica*, and *Fusarium oxysporum*. These pathogens can survive in the soil for a long time and spread and infect through diseased soil, diseased plant debris, and contaminated fertilizer. They often enter through wounds on the roots of tobacco plants, leading to disease. Taking tobacco bacterial wilt as an example, it is a bacterial soil-borne disease caused by *Ralstonia solanacearum*. In the early stages of the disease, as the abundance of pathogens increases, the original rhizosphere soil microbial community structure is disrupted, and the diversity of microorganisms in the tobacco rhizosphere soil decreases. Simultaneously, in the early stages of bacterial wilt, beneficial bacteria such as *Bacillus* and *Oligotrophomonas* are significantly enriched in rhizosphere soil samples. However, as the disease progresses, the diversity of rhizosphere soil microorganisms gradually approaches a dynamic equilibrium. Tobacco bacterial wilt is widespread in major tobacco-producing provinces of my country, even causing outbreaks in some years, resulting in significant losses to tobacco production. Controlling soil-borne diseases of tobacco has always been a global challenge, currently relying mainly on chemical control. However, this method easily leads to environmental pollution and the development of drug resistance in pathogens. Biological control, which does not pollute the natural environment and makes it less likely for pathogens to develop resistance, has gradually become a research hotspot. Recent studies have shown that the occurrence and development of diseases are closely related to the interactions between soil microorganisms and the imbalance of the microbial community. Therefore, regulating the rhizosphere soil microecological environment to suppress soil-borne diseases is becoming a research focus.

[0022] Tobacco soil-borne disease sampling refers to the process of obtaining soil and tobacco plant root samples from fields or experimental environments affected by tobacco soil-borne diseases. These samples are primarily used for subsequent disease detection, diagnosis, and research. The collected samples can be used for several purposes: first, for the detection and identification of pathogens, by extracting DNA or RNA from the samples and using techniques such as PCR to detect the presence of pathogens; second, for analyzing the structure and dynamic changes of soil microbial communities, understanding the interactions of soil microorganisms during disease occurrence; third, for providing a basis for early warning and control of diseases, by monitoring the quantity and types of pathogens in the soil and plants to take measures in advance to reduce the occurrence and spread of diseases; and fourth, for studying the epidemic patterns and pathogenesis of diseases, providing theoretical support for developing more effective control strategies. When collecting samples, soil samples from the root system of disease-infected tobacco plants are typically selected, and each sample is individually packaged and labeled. Collection methods include the five-point sampling method to ensure the representativeness and accuracy of the samples. Collected samples must be properly preserved and transported for subsequent laboratory analysis.

[0023] A tobacco soil-borne disease sampling device is a specialized instrument for collecting soil and related samples affected by tobacco soil-borne diseases. Its primary purpose is to provide accurate samples for disease detection, diagnosis, and research. This device typically includes several key components, such as a fixing rod, a collection block, a cutting block, a sealing cap, and a motor. These components allow the sampling device to penetrate deep into the soil, accurately obtaining soil samples at specific depths and locations. It also enables preliminary sample processing, such as sieving and packaging. Its main uses include: first, collecting soil samples affected by diseases for subsequent pathogen detection and identification; samples obtained through this device more accurately reflect the presence of pathogens in the soil. Second, facilitating observation of the connection between tobacco roots and soil and the relationship with diseases; some sampling devices are specially designed to allow for observation of soil profiles, providing a more intuitive understanding of the distribution and spread of diseases in the soil. Third, improving sampling efficiency and sample quality; compared to traditional sampling methods, specialized sampling devices can obtain samples more quickly and accurately, reducing human interference. In addition, the sampling device has several practical functions. For example, a motor-driven pusher can remove adhering substances from the inner wall of the sampling block, facilitating subsequent use and sample processing. These functions not only improve the convenience of sampling but also ensure the integrity and representativeness of the samples, providing a reliable basis for subsequent laboratory analysis. The main benefits of the tobacco soil-borne disease sample collection device are improved sampling efficiency and ease of subsequent use and sample processing. Secondly, it ensures the integrity and representativeness of the samples. The sampling device can penetrate deep into the soil, accurately obtaining soil samples at specific depths and locations, thus providing a reliable basis for subsequent laboratory analysis. Furthermore, it can reduce human interference with the samples, improving the accuracy and reliability of sampling.

A discharge rack 15 is installed at the lower end of the vibrating screen 8 on one side of the vibrating motor 17. The discharge rack 15 is connected to the vibrating screen 8.
