Description

Technical Field

[0001] The invention relates to the technical field of sampling, and in particular to a sampling device and a sampling method for pepper with bacterial wilt. Background Art

[0002] Pepper bacterial wilt is a disease of pepper caused by Pseudomonas solanacearum. The disease mainly occurs in wounds at the roots of crops. After the pathogen invades the crop, it enters the vascular bundle and blocks the transport system by proliferation, preventing water from entering the stems and leaves, causing wilt. When peppers are diseased, it is necessary to take samples of the pepper plants suspected of being diseased, so that agricultural workers can easily detect whether the pepper plants have bacterial wilt at an early stage.

[0003] The existing sampling of pepper plants is mostly done by agricultural workers using a cutting knife to manually cut the pepper plants. Although this sampling method can sample pepper plants, during the operation, the hands of the farmers are very likely to be cut by the cutting knife, and the safety performance is poor. For this reason, we propose a sampling device and sampling method for pepper with bacterial wilt. Summary of the invention

The cutting knife located in the placing block 1 is fixed on the pressing block 1, and the cutting knife located in the placing block 2 is fixed on the pressing block 2. The cleaned roots of the pepper plants are placed between the placing block 1 and the placing block 2, and the parts to be sampled are placed between the two cutting knives. The pressing block 1 and the pressing block 2 are pressed to drive the pressing block 1, the pressing block 2 and the cutting knife to move vertically. When the displaced cutting knife contacts the roots of the pepper plants, the roots of the pepper plants to be sampled are cut by the cutting knife. When the roots of the pepper plants are cut off by the cutting knife, the cut pepper roots are retained inside the placing block 1 and the placing block 2.

[0006] As a further improvement of the above scheme, the pressing block 1 is embedded with a driving sleeve at one end close to the pressing block 2, and a screw is passed through the internal thread of the driving sleeve.
