Description

A kind of novel corn short mosaic disease viral disease inoculating tool

Technical field

This utility model is related to agri-scientific research field of tool, and in particular to a kind of novel corn short mosaic disease viral disease is inoculated with work Tool.

Background technology

Maize dwarf mosaic is the main Disease of a class in Maize Production, has in each Semen Maydiss producing region in the world and sends out It is raw, for a long time, the yield and quality of Semen Maydiss is drastically influence always, the Semen Maydiss in the area that especially replays to Wheat Maize have can not The harm of appraisal.The sick pathogen is maize dwarf mosaic virus, mainly carries out perishability propagation by vector aphid A kind of systemic disease, is usually expressed as burst, animal migration and intermittent three big characteristics.In China, reported from nineteen sixty-eight first Since road Henan Xinxiang occurs maize dwarf mosaic harm, the disease is sent out in the equal large area of China's Huang-Huai-Hai and northwestern Raw, the corn yield loss that the general disease is caused has become mainly asking for restriction China's Maize Production about in 20%-80% One of topic.

Inoculation method is one of key link of plant viruses research work.The maize dwarf mosaic mirror of national Specification Determine the virus inoculation method in technology, using frictional inoculation method.It is that fresh and tender sick leaf is taken from disease plant, shreds and be placed in aseptic grinding In alms bowl, while adding the phosphate buffer of 0.1mol/l, PH7.0 of 10 times of sick leaf amount, grind under cryogenic, prepare inoculation Suspension.600 appropriate mesh corundum are sprayed being vaccinated on plant leaf before inoculation, then dip a small amount of inoculation with swab stick and suspend Liquid, on blade face, slightly friction causes microtrauma, that is, complete inoculation.But, the frictional inoculation method more wastes time and energy.Therefore, grind It is needed for the work of Vector transmission virus research to study carefully simple and effective artificial inoculation technique.

Utility model content

To solve the above problems, this utility model provides a kind of novel corn short mosaic disease viral disease inoculating tool, improves The work efficiency of Vector transmission virosiss research.

For achieving the above object, the technical scheme that this utility model is taken is：

A kind of novel corn short mosaic disease viral disease inoculating tool, including bamboo pole body, described bamboo pole body one end has swathed 2-3mm thick cotton cloth, is wound with 3-4 layer rustless steel strand layers outside the cotton cloth, the rustless steel strand is irregular flat Flat rustless steel strand, such as stainless steel grinding dust Washing ball；The cotton cloth is using water suction cotton cloth.

Preferably, a width of 2cm of the cotton cloth.

Preferably, the bamboo pole body is cylindric bamboo pole, a length of 20cm, a diameter of 0.6cm.

Preferably, the bamboo pole body is flat column bamboo pole, a length of 20cm, the square column bamboo pole section length of side are 0.5cm.

Preferably, the bamboo pole body lower end side is installed with one handle, opposite side is bolted installation There is metal hose, be easy to capture, and when not in use, can be by the setting of metal hose, it is to avoid whole device is slipped to outstanding In supernatant liquid.

This utility model has the advantages that：

Inoculation suspension is dipped using the inoculator, is slightly rubbed under 1-2 at same direction in maize leaf inoculation position, Blade face cut microtrauma is caused, that is, completes virus inoculation.Using new tool inoculation speed is fast, susceptible effect is good, can carry significantly The work efficiency of high Vector transmission virosiss research.

Specific embodiment

In order that the purpose of this utility model and advantage become more apparent, with reference to embodiments this utility model is entered Row is further described.It should be appreciated that specific embodiment described herein is only to explain this utility model, and without In restriction this utility model.

As shown in Figure 1-Figure 3, this utility model embodiment provides a kind of novel corn short mosaic disease viral disease inoculating tool, Including bamboo pole body 1, described 1 one end of bamboo pole body swathes the thick cotton cloths 2 of 2-3mm, is wound with 3-4 outside the cotton cloth 2 Layer rustless steel strand layer, the rustless steel strand are irregular flat rustless steel strand, such as stainless steel grinding dust Washing ball；The cotton Gauze 2 is using water suction cotton cloth.

A width of 2cm of the cotton cloth 2.

The bamboo pole body 1 be cylindric bamboo pole, a length of 20cm, a diameter of 0.6cm.

The bamboo pole body 1 is flat column bamboo pole, and a length of 20cm, the square column bamboo pole section length of side are 0.5cm.

1 lower end side of the bamboo pole body is installed with one handle 4, and opposite side is bolted that to be provided with metal soft Pipe 5, is easy to capture, and when not in use, can be by the setting of metal hose, it is to avoid whole device is slipped in suspension.

When being originally embodied as making, the cotton cloth of width about 2cm is swathed in one end of tool bamboo pole, it is thick to swathe 2-3mm, then general Steel wire bar winds around cotton yarn and wraps up on head, winds 3-4 layers and is fixed, then solid by binding agent in the other end of bamboo pole Determine handle, be bolted metal hose, that is, make this novel inoculator.Inoculation suspension is dipped using the inoculator, Maize leaf inoculation position is slightly rubbed under 1-2 at same direction, is caused blade face cut microtrauma, that is, is completed virus inoculation.Which is former While reason is to scratch maize leaf epidermal tissue using irregular flat finer wire bar, the cotton yarn of the ill venom liquid of compressive zone, Cell entry leaf tissue, breeding conduction virus is made to cause a disease to plant entirety.

Embodiment

Dry Farm Agricultural Research Centre, Shanxi Academy of Agriculture scientific research personnel is in 2015-2016 in Taiyuan, Linfen two places Field artificial vaccination mirror selects the Maize Mutation Breeding germplasm materials of anti-short mosaic disease, carries out 2 years 4 times inoculations 2 using the inoculator The effect of more than ten thousand strains shows that this inoculation method is easy to operate, and speed is fast, effect is good, compared with conventional vaccination method can time-consuming 1/2 with On, the sickness rate of disease plant is inoculated with up to more than 90%.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be carried out, these improve and Retouching also should be regarded as protection domain of the present utility model.
