Embodiment 1

[0030] A kind of mother kind culture medium special for oyster mushroom, every liter of raw material composition is as follows:

[0031] Degreased peony seed meal 20g, agar 20g, water to 1L.

[0032] The preparation method of above-mentioned oyster mushroom female seed culture medium, step is as follows:

[0033] (1) Take the defatted peony seed meal, dry it until the moisture content is no more than 5wt%, and pass through a 40-mesh sieve after crushing to obtain the defatted peony seed meal powder;

[0034] (2) Take 20g of degreased peony seed meal and 20g of agar in proportion, add them to water, boil for 5 minutes, add water to make up to 1L, divide into test tubes or Erlenmeyer flasks, stopper and bandage, at a temperature of 121°C and a steam pressure of 1.05kg / cm 2 Under the condition of sterilizing for 20 minutes, it is ready.

Embodiment 2

Abstract

The invention relates to a mother strain culture medium specially used for oyster mushroom, and a preparation method and applications thereof. The mother strain culture medium specially used for oyster mushroom is prepared from 20 to 100g of degreased peony seed meal, 18 to 20g of agar, and 1000ml of water. According to the preparation method, peony seed meal is taken as a raw material to prepare the mother strain culture medium specially used for oyster mushroom, so that the mother strain culture medium is suitable for growth of oyster mushroom mycelia, obvious advantages in the aspects of mycelia growth speed, growth state, living weight, pretreatment time, and raw material cost are achieved, novel raw material sources are provided for oyster mushroom mother strain production, production technology is simplified, the cost of mother strain culture is reduced, and the time of culture is shortened.

Description

technical field [0001] The invention relates to a special mother seed culture medium for oyster mushrooms, a preparation method and application thereof, and belongs to the technical field of edible fungus cultivation. Background technique [0002] The edible fungus industry is a circular, efficient, and ecological modern agricultural industry, and it is a typical facility agriculture. At present, the annual output of edible fungi in my country accounts for more than 75% of the world's total output. In my country's agricultural economy, its annual output value is second only to grain, oil, vegetables, and fruits, ranking fifth, and has become an important industry in the agricultural economy. In 2015, the total national output of edible fungi was 34.7615 million tons, of which Pleurotus ostreatus was 5.9018 million tons, accounting for 16.98%. It is the third largest mushroom species after shiitake mushrooms and fungus, and it is also one of the most accepted mushroom species...
