Authenticating frame and rice seedling stage rhizoctonia solani authenticating device comprising authenticating frame

Abstract

The invention belongs to the technical field of culturing frames, and particularly provides an authenticating frame and a rice seedling stage rhizoctonia solani authenticating device comprising the authenticating frame. The authenticating frame comprises a square frame body with supporting feet and partition plates; a connecting rod is arranged on each of the two sides of the frame body; a supporting rod is arranged on the side surface, adjacent to each connecting rod, on the frame body; each supporting rod is provided with through holes and supporting inserting blocks which are matched with the through holes; the middle parts of the two sides of each partition plate are hinged to the frame body through the connecting rods; one end of each partition plate is erected on the corresponding supporting inserting block; protruded partition strips are arranged on each partition plate at intervals and are parallel to the connecting rods; a film rod extending out of the frame body is also arranged above each supporting foot on the frame body; each film rod is provided with a first film rod and a second film which are respectively parallel to adjacent side surfaces of the frame body. The partition plates of the authenticating frame are adjustable so as to facilitate the observation of crop growth situations inside the authenticating frame; the arrangement of the structures, such as the film rods, is convenient for covering the authenticating frame with a thin film and facilitates the adjustment of the temperature and the humidity in the authenticating frame.

Description

technical field [0001] The invention belongs to the technical field of cultivation racks, and specifically provides an identification rack and a rice sheath blight identification device comprising the same. Background technique [0002] Sheath blight is a fungal disease caused by Rhizoctonia solani. It is one of the most common major diseases of rice. Generally, the early rice is heavier than the late rice, which often causes the grains to be not full, the empty shell rate increases, and the serious ones can cause the plants to fall and die. Therefore, the identification of sheath blight in rice seedlings is of great significance for the selection and breeding of new rice varieties. At present, the identification of rice sheath blight at the seedling stage in the laboratory is generally to put the potted rice at the seedling stage on a wooden frame, and then cover the wooden frame with a film, and place a humidifier inside the film to adjust the humidity of the rice at the ...

AI Technical Summary

Problems solved by technology

Because the structure of the wooden frame is relatively simple, and each experiment is generally set up at the same time, multiple rows of potted rice are usually placed on each layer of each wooden frame, and the partitions are horizontal, so it is not easy to observe the placement. Whether the rice on the inside of the wooden frame is sick or not, it is more troublesome to stick your head in to observe

On the other hand, the unbalanced temperature and humidity in the film will also affect the experimental results
