Populus tremula grey speck disease germ spore production culture medium as well as preparation method and application method thereof

Abstract

The invention discloses a populus tremula grey speck disease germ spore production culture medium as well as a preparation method and an application method thereof, relating to a plant pathogen fungus spore production culture medium as well as an preparation method and an application method thereof, and aiming at solving the problem that an existing fungus culture medium cannot well meet the requirement for the spore production through the growth and development of populus tremula grey speck disease germs. The spore production culture medium is prepared from potato, peptone, monopotassium phosphate, magnesium sulfate, agar and the balance of distilled water. The preparation method of the spore production culture medium comprises the following steps of peeling potatoes, boiling the peeled potatoes for 20 minutes to 30 minutes, filtering to obtain the filter liquid, dissolving the peptone, the monopotassium phosphate, the magnesium sulfate and the agar into the filter liquid, and fixing the volume to 1L by utilizing the distilled water so as to complete the preparation of the populus tremula grey speck disease germ spore production culture medium. The culture conditions of the culture medium are as follows: the temperature is 19 to 30 DEG C, and the culture period is 7 to 30 days. The populus tremula grey speck disease germ spore production culture medium as well as the preparation method and the application method disclosed by the invention are applied to the field of microorganism culture.

Description

technical field [0001] The present invention relates to a plant pathogenic fungus sporulation medium and its preparation method and use method, mainly related to the sporulation medium of poplar gray spot fungus (Sporocadus populinus Orsenigo, Rodondi&B.Sutton=Coryneum populinum Bres.) and its preparation method and how to use it. Background technique [0002] Poplar (Populus spp.) has the characteristics of fast growth, early maturity, strong adaptability, easy renewal, good material and wide application, so it is planted in large areas in the north. Poplar is the main species of timber forest, shelter forest and urban greening in northern my country. [0003] Poplar gray spot (S.populinus) is a great threat to poplar seedling cultivation and afforestation. It is the most common and serious disease in the seedling stage of poplar. It mainly occurs on the leaves, tips and stems of annual seedlings and saplings. The causative bacterium of poplar gray spot disease (S.populin...
