Preparation method of nostoc commune culture medium

Abstract

The invention discloses a preparation method of a nostoc commune culture medium. The preparation method comprises the following steps of: by taking green plant corncobs convenient to obtain, wide in source and capable of storing drained water and nutrients as raw materials according to the biological characteristics of nostoc commune, burdening, soaking a nutrient solution and drying to prepare the nostoc commune culture medium which is optimized, rich in nutrient substances required for adsorption growth of nostoc commune, ventilatory, water-permeable, low in production cost and pollution-free. The culture medium is rod-shaped. When the culture medium is applied, a single layer of culture medium is distributed and arranged on a culture bed; during seeding, nostoc commune frond can be directly spread on the culture medium, thus a new safe and effective material which is convenient to update and change after harvesting is provided for implementing artificial soiless high-yield cultivation inside and outside a nostoc commune room. As the nostoc commune culture medium is rough and uneven in surface, the nostoc commune culture medium has a very good preventive effect on cultivation destructive disease waterlogging nostoc commune rotting often caused by common insect pests such as slugs and snails in nostoc commune and poor water drainage in an underlying surface.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preparing a fungus culture medium. Background technique [0002] Ground fungus, also known as ground mushroom, Nostoc, lichen, and ground vegetable, is a sheet-shaped algae of the genus Nostoc. It appeared in the ancient times and is the simplest and most primitive plant group left on the earth today. It has multiplied in the unique wilderness environment for thousands of years. According to analysis, ground fungus is rich in protein, multivitamins and trace elements. Its protein content is higher than that of eggs and white fungus, and its vitamin C content is 19 times that of laver. At the same time, the content of trace elements calcium, iron, phosphorus and zinc are all higher than General edible fungus 5-15 times. In addition to nutritional ingredients, ground fungus has been recorded in many classical medical and agricultural works in our country. natural wild v...
