Technical Field

[0001] The utility model relates to a flue-cured tobacco rhizosphere positioning sampling device, belonging to the technical field of tobacco rhizosphere sampling. Background Art

[0002] Tobacco rhizosphere sampling refers to sampling in the rhizosphere of tobacco to obtain relevant information such as soil, root system and microorganisms. This is a commonly used soil research method that can understand the impact of the rhizosphere microenvironment of tobacco on tobacco growth and quality, and provide a basis for scientific planting and management of tobacco.

[0003] The existing tobacco rhizosphere sampling is mostly done by excavating the tobacco rhizosphere during the tobacco growth process and then sampling. This method has the problem that the surrounding soil is easily mixed with the sampled soil after excavation, affecting the sampling effect. At the same time, it is relatively troublesome in operation.

[0004] Therefore, there is a need for a flue-cured tobacco rhizosphere sampling device that can facilitate sampling of the tobacco rhizosphere and improve the quality of sampling. Utility Model Content

[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for explaining the present utility model and not for limiting the protection scope of the present utility model.

[0024] As Figure 1 - Figure 2 shown, a flue-cured tobacco rhizosphere positioning sampling device disclosed by the present utility model includes a sampler body 1 embedded near the rhizosphere of flue-cured tobacco. A sampling cavity 2 is arranged in the sampler body 1. Through holes for the roots and soil of flue-cured tobacco to enter the sampling cavity 2 are distributed on the side wall of the sampler body 1. A pull rope 3 is arranged at the upper end of the sampler body 1. With such a structure, before transplanting tobacco, the sampler body 1 is pre-embedded first. During pre-embedding, the sampler body 1 is pre-embedded at a fixed distance from the tobacco transplanting well cellar. During the growth of tobacco, when it is necessary to sample the rhizosphere sample, the sampler body 1 is pulled out through the pull rope 3, and at the same time, the sampler body 1 and the sampled sample are taken out, so as to realize the sampling of the tobacco rhizosphere.

[0025] Furthermore, a pre-embedding depth mark is arranged on the outer wall of the sampler body 1. With such a structure, the samples at different depths in the sampler body 1 are classified through the pre-embedding depth mark, which is beneficial for classified research.

[0026] Furthermore, the sampler body 1 is a cage body, and a supporting net 4 is arranged at the bottom of the cage body. With such a structure, the cage holes arranged on the cage body serve as through holes for the roots and soil of flue-cured tobacco to enter the sampling cavity 2. This facilitates the entry of the roots and soil in the tobacco rhizosphere into the cage body after pre-embedding. Through the supporting net 4, it is beneficial to avoid the roots and soil in the cage body from falling off when the cage body is pulled out. At the same time, through the supporting net 4, the roots and soil can also enter the cage body from the bottom of the cage body. This structure is only one of the structures of the sampler body 1, and other devices suitable for pre-embedded sampling are within the protection scope of this application, such as a sampling tank with through holes arranged on it. Furthermore, a marking ring 5 indicating the pre-embedding depth mark and a structure strengthening ring 6 are arranged on the cage body. In this way, it is beneficial to grasp the pre-embedding depth through the marking ring 5. At the same time, after sampling, the sample can be divided at the marking ring 5, which is beneficial for classifying and sorting the sample.

[0027] Furthermore, a cage cover 7 is arranged above the cage body. The cage cover 7 is movably connected to the cage body. One end of the pull rope 3 is connected to the cage cover 7. Through the cage cover 7, it is beneficial to open the cage to take out the sample. Specifically, a protrusion that is mutually clamped with the cage body is arranged at the lower end of the cage cover 7. During use, in order to prevent the cage cover 7 from detaching when the pull rope 3 pulls out the cage body, the cage cover 7 and the cage body are tied to each other through a wire or the like.
