Problems solved by technology

At present, there is no report on the artificial rotation of raising bat moth larvae in China. There are only reports on the study of extravagant feeding and food intake of bat moth larvae (Zhang Deli et al., Research on extravagant feeding and food intake of bat moth larvae, Southwest Agricultural Journal, 2014 Volume 27, Issue 6, 2732-2734.), does not mention rotation feeding

[0039] Reference Example 2. Screening of Salvia Miltiorrhiza

[0040] Screening process: More than 100 kinds of Chinese herbal medicines or ingredients were tested, and the following 8 kinds of ingredients that can meet large-scale production were selected from the feeding effect, shelf life, and larval growth parameters. The comparative feeding effects of Danshen Polygonum villosa, small rhubarb, Polygonum rotundum, Gastrodia chinensis, Jerusalem artichoke, caddis, and carrots are shown in the table below.

Embodiment 1

[0042] Embodiment 1 The selection of feed by bat moth larvae in different age stages

[0043] Place a filter paper for moisturizing in a transparent plastic Petri dish with a diameter of 12cm, and cut the rhizomes of optional ingredients into 1cm 3Cube-shaped size, and placed on the filter paper in a circle evenly along the periphery of the petri dish. There are 2 pieces of each plant rhizome in each device. For example, in this scheme, the larvae choose to feed on 8 kinds of plant rhizomes. The order is ABCDEFGHABCDEFGH. At the beginning of the experiment, the 1, 2, 3, 4, 5, 6, and 7 instar larvae of the tested bat moth after 24 hours of starvation treatment were placed in the center of 7 pieces of wet filter paper, and the lids of the petri dishes were respectively covered, and then placed Measure selectivity under the conditions of temperature 12°C, humidity 80%, light intensity 15W, L:D=14h:10h (ratio of light time and dark treatment time in one day), place 30 larvae in e...

Abstract

The invention provides a method for breeding cordyceps sinensis host larvae in turns. The method mainly comprises the following steps that 1, the two-year-old larvae are bred through the mixture of serpentgrass, bistorta macrophylla and rheum pumilum; 2, the 3-year-old, 4-year-old and 5-year-old larvae are bred through the mixture of salvia miltiorrhiza, stachys sieboldii and rheum pumilum; 3, the larvae getting into the final age are bred through the mixture of carrots, jerusalem artichoke, rheum pumilum and salvia miltiorrhiza. By means of cyclic breeding, the host larvae can absorb balanced nutrition at the whole growth stage, the nutrition lack disease of the larvae is solved, it can be ensured that subsequent cordyceps sinensis has high quality, and the growth period of the larvae is shortened.

Description

technical field [0001] The invention relates to a method for feeding the host larvae of Cordyceps sinensis in rotation. Background technique [0002] Because Cordyceps sinensis grows in the Qinghai-Tibet Plateau at an altitude of 3000-5000 meters, the natural parasitic rate is low and the living environment conditions are extremely harsh, so its own resources are very limited. In recent years, due to the large market demand and the continuous rise in prices, a large number of blind and unreasonable excavations have been caused. , leading to a decrease in wild resources and a decrease in yield year by year, the artificial propagation system of the mature host larvae of Cordyceps sinensis is a technical problem urgently needed to be solved by those skilled in the art. [0003] Now the fresh food materials of artificially raising bat moth larvae are generally single, such as only using carrots, Polygonum victoriae, etc. to raise bat moth larvae alone, and also using carrots, ma...
