Embodiment 1

[0029] Bacteria isolation and identification

[0030] Collection of strains: In September 2006, the inventor Li Guojun collected the Cordyceps militaris strains from the wild Cordyceps militaris production area in the southern extension of Hadaling, Changbai Mountains, Jilin Province, and cultivated Cordyceps militaris in the culture medium. The biological characteristics were observed, detected and identified, and it was non-toxic. , high content of cordycepin, identified as the Paecilomyces militaris strain, and domesticated through multiple generations of subculture to become the Cordyceps militaris strain Qinchong No. 1 capable of infecting dried silkworm chrysalis.

[0031] A dried silkworm Cordyceps militaris, which is a complex of dried silkworm chrysalis and grass transformed through artificial cultivation by infecting dry silkworm chrysalis with the Cordyceps militaris strain Qinchong No. 1; the preservation number of the Cordyceps militaris strain Qinchong No. 1 is ...

Abstract

The invention relates to dried silkworm cordyceps militaris. A preparation method of the dried silkworm cordyceps militaris comprises the following steps: infecting a host silkworm chrysalis with a cordyceps militaris fungus No.1, and carrying out artificial culture and conversion so as to form the dried silkworm cordyceps militaris, namely a complex of the dried silkworm chrysalis and the cordyceps militaris. The success rate of the dried silkworm cordyceps militaris in scale production is greater than or equal to 98%, the dried silkworm cordyceps militaris can be stored for 3 to 4 years, i.e., so that the storing period of the dried silkworm cordyceps militaris is longer than that of plumeria rubra acutifolia cordyceps militaris, and the content of nutritional ingredients in the dried silkworm cordyceps militaris is higher than that of the nutritional ingredients in the plumeria rubra acutifolia cordyceps militaris. In addition, the cultured dried silkworm cordyceps militaris is golden yellow in colour and lustre, i.e., the ornamental value is good. The cultured dried silkworm cordyceps militaris has obvious effects for treating high blood pressure, high blood fat, high blood sugar, kidney diseases, digestive system diseases, nervous system diseases and cardiovascular and cerebrovascular diseases. Thus, the dried silkworm cordyceps militaris is superior to cordyceps sinensis and natural cordyceps militaris.

Description

technical field [0001] The invention relates to the technical field of Cordyceps militaris, in particular to a dried Cordyceps militaris and a cultivation method thereof. Background technique [0002] At present, the artificial production of Cordyceps at home and abroad mainly uses live silkworm chrysalis to produce Cordyceps militaris. The specific method is: under aseptic conditions, live silkworm chrysalis are injected with strains one by one. Adopt this method to produce Cordyceps militaris, the success rate is low, generally ≤ 60%, work efficiency is low, each person injects ≤ 110 per hour, and production cost is high, and every kilogram of Cordyceps militaris ≥ 2500 yuan, therefore, it is difficult to implement large-scale production. [0003] Chinese patent CN103210787B discloses a Cordyceps militaris strain (Cordyceps militaris) Qinchong No. 1, Cordyceps militaris with preservation number CGMCC NO.6808, its cultivation method and application. Infect the host poultry...
