Rapid detection device of plant germs

Abstract

The invention discloses a rapid detection device of plant germs. The rapid detection device comprises a kit, a light guide body arranged in the kit and a plurality of light source pieces arranged on two sides of the kit. Grooves are arranged in the two sides of the light guide body; a plurality of test solution channels are arranged in the light guide body at intervals, the plurality of test solution channels are distributed in parallel, an ultraviolet excitation layer is arranged on a wall of each groove, each light source piece transversely irradiates the ultraviolet excitation layer at thegroove of the light guide body to excite ultraviolet light, and the ultraviolet light penetrates through the light guide body to irradiate a sample solution in the test solution channels; the light guide body is connected with the kit in an inserting manner, and a flexible light-transmitting film is arranged on the surface of the light guide body; a liquid outlet is arranged in the end of the light guide body, a temporary storage cavity is connected to the end of the liquid outlet, and an air bag is connected to the end of the temporary storage cavity; a display part is arranged on one side ofthe light guide body and can display a fluorescent band; and the plant germs are detected according to characteristics of the fluorescent band.

Description

technical field [0001] The invention relates to the field of germ detection and the field of test strip detection, in particular to a rapid detection device for plant germs. Background technique [0002] Tobacco bacterial wilt is a vascular disease caused by Laueria solani. It is difficult to detect with the naked eye at the initial stage. Once wilting symptoms appear, drug control is no longer effective. Strengthening the detection of tobacco roots that are not infected with the disease, and early prevention and control is the key. Research It shows that the incidence of tobacco plants increases with the increase of the number of R. solanacearum bacteria in tobacco roots and foot leaves. This kit is a new type of bacteria detection product based on monoclonal antibody and time-resolved fluorescence technology. It is quick and easy to operate. , and the number of R. solanacearum bacteria in leaves are detected for early detection and precise treatment. [0003] Traditional ...

Problems solved by technology

[0003] Traditional detection devices can only perform ultraviolet light irradiation with fixed characteristics, and it is difficult to realize ultraviolet light excitation with different characteristics. In the process of detecting plant pathogens, the operation is more troublesome. The existing detection methods for R. solanacearum are mainly molecular biological detection. Methods Compared with conventional assays, molecular biology assays such as quantitative PCR assays can accurately obtain the number of R. solanacearum bacteria, but the process is more complicated, the technique is difficult, and the requirements for operators are higher.

The disadvantage of the conventional measurement method is that the detection cycle is long and the misjudgment rate for beginners is high, and it is difficult to meet the requirements of fast and accurate
