Culture substrate for test-tube strain of Lactarius deliciosus and preparation method thereof, and culture method for test-tube strain

Abstract

The invention provides a culture substrate for a test-tube strain of Lactarius deliciosus. The culture substrate is prepared from the following components by weight: 1 to 3 parts of potatoes, 0.2 to 0.5 part of wheat, 0.2 to 0.3 part of glucose, 0.05 to 0.15 part of potassium dihydrogen phosphate, 0.5 to 1.0 part of pinewood ash and 0.1 to 0.3 part of agar. The culture substrate provided by the invention can be used for culturing of the test-tube strain of the Lactarius deliciosus.

Description

technical field [0001] The invention relates to the technical field of edible fungi, in particular to a cygonia test tube culture substrate, a preparation method and a test tube culture method. Background technique [0002] Swan fungus is a kind of edible fungus. It is the best when the pine flowers fall to the ground during the cold dew. It is delicious and fragrant. Mushroom fruiting bodies generally grow in groups, and often grow at the turn of spring and summer and the end of autumn and early winter, forming a mycorrhizal relationship with Pinus massoniana. In the mountains and hills of Songzi, Pinus massoniana forests are widely distributed and the climate is humid, which is suitable for the growth of Cygnus swani. The pine forests in Baojing, Xiangxi, Hunan, Linli, and Songzikou on the south bank of the Yangtze River have the most yield and the best quality. [0003] After the successful separation of Cygnus spores or fruiting bodies, they have not been able to adapt ...
