Abstract

The invention belongs to the field of biotechnology equipment, and in particular relates to a petri dish for cultivating plasmopara viticola. The petri dish comprises a petri dish cover (1), a petri dish box (3) and a support sieve (2), wherein the petri dish cover (1) is provided with a cover edge (1.1), a cover ring (1.2) and a hemispherical mist flushing point (1.3); the support sieve (2) is provided with a sealing ring (2.1), sieve pores (2.2) and support pillars (2.3); the petri dish box (3) is provided with a mist inlet tube and a water outlet tube, and a mist outlet (3.3) of the mist inlet tube is formed upwards in an inclined way; the water outlet tube is internally provided with through degreasing cotton (4.3). A plate is made from a transparent plastic material, so that the growth situation of the plasmopara viticola in the petri dish can be conveniently observed. The petri dish reduces the probability that leaves are infected by bacteria; the petri dish is internally connected with a humidifier, so that the mist is even during culturing, and the cultured plasmopara viticola is higher in activity.

Description

technical field [0001] The invention belongs to the field of biotechnology equipment, in particular to a petri dish for cultivating peronospora on grapes. Background technique [0002] The petri dish is a kind of vessel commonly used in various fields such as biology, and has universal practicability. [0003] Grape downy mildew is a relatively common disease of grapes. It breaks out seriously in summer and autumn every year. In recent years, there have been many studies on downy mildew. However, there is no practical medium for downy mildew to cultivate downy mildew. The current The method is to use a petri dish to cultivate on isolated grape leaves; wherein, during the culturing process, the agar medium or filter paper that has been sucked with water is mainly used for moisturizing, and a sealing film is used to seal the gap of the petri dish. [0004] However, in the method of using a petri dish to inoculate the grape leaves with downy mildew, more water droplets should ...
