Description

A test tube for preservation of plant pathogenic fungi

technical field

The utility model relates to a tool for preserving plant pathogenic fungi, in particular to a test tube for preserving plant pathogenic fungi.

Background technique

Fungal diseases are the most serious types of plant diseases. Most of the pathogenic fungi are cultivable microorganisms that can grow and reproduce on certain nutrient substrates. The preservation of plant pathogenic fungi is crucial to the study of fungal diseases, and it is the premise and basis for carrying out research on plant fungal disease etiology, epidemiology, and control technology. The preservation of phytopathogenic fungi in conventional laboratories generally adopts the glass test tube slope preservation method, that is, injecting the culture medium into the glass test tube to form a slope, plugging the test tube mouth with a cotton plug, and using it after sterilization. Generally, the glass test tube used to make the slope is about 20 ml, and the volume is relatively large. This method needs to consume more culture medium and take up more space when storing; after the slope is used, the cleaning process of the glass test tube is also cumbersome; use a cotton plug to seal It is not conducive to the long-term preservation of the slope, and it is easy to be polluted.

Utility model content

The purpose of the utility model is to provide a test tube for preserving phytopathogenic fungi, which can make the preservation cost of phytopathogenic fungi lower, easy to use, easy to store and difficult to pollute.

The utility model is implemented by the following technical scheme: a test tube for preserving plant pathogenic fungi, which includes a test tube main body and a tube cover. The test tube main body is cylindrical, the bottom of the test tube main body is sealed and conical, and the top is a circular orifice; the upper outer wall of the test tube main body is provided with an outer spiral ring; the middle outer wall of the test tube main body Labels are provided; the tube cover is arranged at the top opening of the test tube body, the tube cover is cylindrical, one end is sealed, and the other end is a circular hole; the inner wall of the tube cover is provided with a tube cover inside A spiral ring; the sealing end of the tube cover is provided with a disc-shaped rubber pad.

The utility model has the advantages: the spiral combination design of the test tube body and the tube cover, and the built-in rubber pad of the tube cover make the fungus preservation not easy to be polluted; the test tube is small in size, easy to operate, and saves the cleaning process of the conventional glass test tube; saves cultivation base, reducing the preservation cost of fungi.

Detailed ways

The utility model will be further described in conjunction with the accompanying drawings and specific examples, but not as a limitation to the utility model.

A test tube for preserving plant pathogenic fungi, which includes a test tube body 1 and a tube cover 2, the test tube body 1 is cylindrical, the bottom is sealed, and it is conical, and the height of the cone does not exceed 1/4 of the height of the test tube body. Under the premise of affecting the production effect of the inclined surface, the conical design saves the amount of culture medium; the top of the test tube main body 1 is a circular hole; the upper outer wall of the test tube main body 1 is provided with an outer spiral ring 3; There is a label 4 for recording information such as fungal species; the tube cover 2 is arranged on the top opening of the test tube main body 1, the tube cover 2 is cylindrical, one end is sealed, and the other end is a circular orifice; the inner wall of the tube cover 2 is set There is an inner helical ring 5 of the tube cover, which can be combined with the outer helical ring 3 in rotation; the sealing end of the tube cover 2 is provided with a disc-shaped rubber pad 6, which can make the test tube form a closed space and improve the preservation effect of fungi.

Instructions for use: Take 1.2mL of prepared culture medium and pour it into the main body of the test tube 1, and screw on the cap 2 gently, but do not tighten it tightly. Put the test tube into a sterilizer for high-temperature and high-humidity sterilization, take it out, put it on an inclined plane and tighten the cap 2 tightly. Open the tube cover 2 under sterile or ultra-clean conditions, transfer the phytopathogenic fungi to the test tube body 1, tighten the tube cover 2, mark the fungal species, date and other information on the label 4, put the test tube in the incubator After cultivating for 3-5 days, the preservation of the plant pathogenic fungus can be completed by placing it in a low-temperature environment.
