Cultivation method of cordyceps militaris

Abstract

The invention relates to a cultivation method of cordyceps militaris. A culture medium comprises the following nutrition ingredients in percentage by weight: 87% of long-shaped rice, 4.3% of silkworm chrysalis meal, 4.6% of glucose, 3.2% of peptone, 0.25% of monopotassium phosphate, 0.25% of magnesium sulfate, 0.25% of ammonium citrate and 0.15% of VB1. The cultivation method comprises the steps that the nutrition ingredients and water are mixed, wherein the water content is controlled at 60%, and the pH value is controlled to be between 6.0-6.5; the culture medium is loaded into boxes, and is subjected to sterilization and inoculation, and dark culture is carried out for 10 days for generating hypha at the temperature of 20-21 DEG C and the relative humidity between 55%-60%; the single-layer cordyceps militaris fungus boxes full of hypha are arrayed on a cultivation frame, transparent moisturizing materials cover the fungus boxes, ventilation and moisture increment are carried out by using an air regenerating device and humidifying equipment, the fungus boxes are exposed to light for color change, after 3 days the temperature difference is increased for promoting anlage formation, and harvesting is carried out when the cordyceps militaris grows to about 5cm long. Compared with the existing cordyceps militaris, the cordyceps militaris cultivated according to the method disclosed by the invention has the advantages that a part of technical indexes surpass the technical indexes of the existing cordyceps militaris, and the edible and medicinal values are high.

Description

technical field [0001] The invention relates to the field of edible fungi, in particular to a method for cultivating Cordyceps militaris. Background technique [0002] Natural Cordyceps is mainly produced on the Qinghai-Tibet Plateau at an altitude of 3,000 m or more. Limited by the growing area, natural resources are scarce and expensive. The unit price of Cordyceps sinensis is about 88-385 yuan per gram. While the price is expensive, the market inventory is not large. The number of naturally growing Cordyceps sinensis is relatively limited, and artificial cultivation is very difficult, and it is difficult to form sub-seats. At present, the edible and medicinal value of Cordyceps militaris in the market has been scientifically proven, and its effect is not worse than that of Cordyceps sinensis, and sometimes it is even better than that of Cordyceps sinensis. Therefore, Cordyceps militaris can become a substitute of Cordyceps sinensis, and its price is not less than that of ...
