Inoculator for common cassava mosaic viruses

Abstract

The invention discloses an inoculator for common cassava mosaic viruses, belongs to the field of plant pathogen inoculation tools, and aims to overcome the defect that manual inoculation wastes time and labor in the prior art. The inoculator comprises a shell attached to cassava branches and a cutter sliding on the surface of the shell. The surface of the shell is provided with through holes whichare arranged in lines. The cutter is provided with a sliding sleeve attached to the shell. The cross section of the sliding sleeve is a split cylinder; a cutting blade is arranged at the head end ofthe sliding sleeve; a pressing plate is fixedly connected to a cutter handle of the cutting blade, a telescopic piece serving as a pressing plate fulcrum is connected to the bottom of the pressing plate, and the telescopic piece is in a compressed state when not passing through the through hole. The pressing plate and one end of the cutting blade descend when the telescopic piece is straightened,the movement stroke of the pressing plate is located outside the sliding sleeve, and a rotating shaft passes through the pressing plate close to the cutting blade. According to the inoculator, the cutting function of the inoculation link is achieved, manual cutting is avoided, the generated torque is provided by the telescopic piece, and the strength of an operator is saved.

Description

technical field [0001] The invention belongs to the field of inoculation equipment for plant pathogens, in particular to an inoculator for cassava common mosaic virus. Background technique [0002] Cassava common mosaic virus (CsCMV) is a member of the genus Potexvirus. Its genome is a linear virus composed of a positive-strand RNA with a genome size of 6.4kb. Cassava common mosaic virus infection can cause typical mosaic disease on most cassava (Manihot esculenta) varieties, manifested as leaf mosaic, rough shape, narrow base, etc., similar to African cassava mosaic symptoms, but the latter is It is caused by another African cassava mosaic virus (ACMV) infection. Cassava common mosaic virus infection can cause 30% loss of cassava root yield. Under natural conditions, CsCMV can be transmitted by sap and friction. [0003] In view of the pathogenic characteristics and specificity of cassava common mosaic virus, the following methods are usually used for inoculation in expe...

Problems solved by technology

[0004] In view of the above reasons, for the controllability of cassava mosaic virus inoculation, the method of friction inoculation is generally used, but the inoculation devices currently on the market are usually for woody plants. Plants, while cassava belongs to upright shrub crops, the branches are small and weak, and the degree of lignification of the branches is not high. Using a grafting device such as the prior art with the notification number of CN109068593A usually damages its pith, resulting in dead seedlings The rate is very high, so the laboratory generally adopts manual friction inoculation when inoculating the virus
