Plant quarantine tissue slice device

Abstract

The invention provides a plant quarantine tissue slice device comprising a cutter and a second connecting pipe; a pumping groove is a chamber groove structure, front and rear plate-like structure support vertical plates are arranged on the bottom surface of the pumping groove, a sampling box and a culture liquid storage tank are further installed from the left to the right on the bottom side of the pumping groove, a rectangular structure notch is arranged on the rear wall, near the left side, of the inner cavity of the pumping groove; a first connecting pipe is connected to between the cultureliquid storage tank and a second connecting pipe, and the other end of the second connecting pipe is connected to a funnel; the plant quarantine tissue slice device is used to sample a stem of a plant, the plant quarantine tissue slice device is relatively closed, and can simultaneously realize the synchronous and relatively-closed dripping of a culture liquid. Compared with the existing plant quarantine tissue slice sampling device, the plant quarantine tissue slice device has higher operability, and greatly reduces the probability of contact with the outside air during sampling, and the sampling process is relatively more closed, so that when subsequent sampled samples are observed by a microscope, the effect is better.

Description

technical field [0001] The invention belongs to the technical field of slicing device structure, and in particular relates to a tissue slicing device for plant quarantine. Background technique [0002] Phytosanitary measures to prevent the spread of harmful organisms in the circulation of plants and their products by means of legislation. An aspect of plant protection characterized by the macroscopic prevention of the introduction, establishment and spread of all pests, especially those not found in the region. Because it is legally mandatory, "prevention by regulations" and "prevention by administrative measures" are often used as synonyms in international literature. [0003] Similar to Chinese Patent No.: CN201420599164.6, a phytosanitary sample bottle is provided, which is described as including a bottle body and a bottle cap, the bottle body includes a bottleneck, and the bottle neck of the bottle body is connected by a screw thread and the bottle cap, and the bottle b...

AI Technical Summary

Problems solved by technology

The sampling devices similar to the above-mentioned structures either have a single structure, poor functionality, or are large in size. During the sampling process, the section of the sectioned plant stem is easy to have a greater chance of contact with external air, causing the sectioned sample to be exposed under a subsequent microscope. When observing, there are many other material tissues in the tissue structure, which affects the viewing effect. Therefore, this structure adopts a relatively small slicing device that can realize the relatively closed slicing and culture solution processing process.
