Castor silkworm cordyceps militaris artificial cultivation method

Abstract

The invention discloses a castor silkworm cordyceps militaris artificial cultivation method. The method comprises the steps of castor silkworm feeding, host silkworm feeding and selecting, cordyceps militaris mother strain selection, host silkworm inoculation and spawn running and the like. Accordingly, by means of liquid strain, larvae of castor silkworms serve as a combination of a host and cordyceps militaris, the active ingredient content of the cultivated cordyceps militaris is high, and particularly the SOD content is higher than cordyceps sinensis. The advantages of research and development of the castor silkworms and the cordyceps militaris in Guangxi are fully utilized, and the method make a contribution to high-quality and cheap health-care products provided for people and healthlevel improvement.

Description

technical field

[0001] The invention relates to the technical field of artificial cultivation of Cordyceps, in particular to the artificial cultivation of Cordyceps by using castor silkworm larvae. Background technique

[0002] Castor silkworm, also known as cassava silkworm in Guangxi. In 1951, my country once again introduced castor silkworm for trial cultivation and promoted it. From 1964 to 1966, it was widely promoted nationwide, and a large scale of castor silkworm industry was formed, and the industry reached its heyday. However, in the field of research and development of castor silkworm comprehensive utilization, it is learned from literature review that before the end of the 1980s, silkworm cocoons were mainly harvested inside and outside the region, and silkworm chrysalis was used as a source of edible protein to improve the living conditions of rural people. At the same time, silkworm excrement is used as fertilizer for processing and reuse. Since the end of the...

Examples

Embodiment 1

[0022] The artificial cultivation of castor silkworm Cordyceps requires a feed field, a silkworm room and a laboratory for inoculating and cultivating Cordyceps, as well as necessary silkworm tools and experimental equipment. The location of infrastructure establishment should comprehensively consider climatic conditions, environmental pollution, convenient transportation and so on. Then do a good job in the planting of castor and cassava feed, as well as field management.

[0023] In early October 2017, castor leaves were used to raise silkworms, and the feeding management was implemented in accordance with the technical regulations for raising castor silkworms. According to the yield of castor leaves and the number of larvae required for artificial cultivation of castor silkworm Cordyceps, 6~ 8 grams. Harvest ants at the right time, raise small silkworms carefully, disinfect large silkworms to prevent diseases, eat good leaves, and make silkworms strong.

Embodiment 2

[0039] In late November 2017, cassava leaves were used to raise silkworms, and the feeding management was implemented in accordance with the technical regulations for raising castor silkworms. It was planned to use 6-8 grams of silkworm eggs. Harvest ants at the right time, raise small silkworms carefully, disinfect large silkworms to prevent diseases, eat good leaves, and make silkworms strong.

[0040] Do a good job in the cultivation of Cordyceps liquid strains, and the cultivation time of the strains is synchronized with the feeding time of silkworms from the fourth instar. Cordyceps liquid culture is divided into three steps:

[0041] The first step: prepare liquid culture medium, the formula is: potato (peeled) 15%, potassium dihydrogen phosphate 0.05%, glucose 2.0%, magnesium sulfate 0.1%, peptone 2.0%, sodium chloride 0.1%, ph value Natural; the total amount of preparation is calculated according to the success of normal culture, and 200 silkworms can be connected to ...
