Problems solved by technology

[0003] At present, the source of medicinal materials of Guangdilong is mainly from artificially caught wild resources, resulting in an extreme shortage of wild Dilong
At the same time, wild resources also have problems of mixed varieties, uneven sizes, and unclear sources, which makes the quality of earthworm medicinal materials unable to be guaranteed.
The main technical defect is that, because the worm has not been artificially domesticated, it is wild, has strict requirements on the living environment, is easy to escape, and is difficult to cultivate artificially.

Embodiment 1

[0030] Embodiment one: the preparation of the nutrient matrix of C. chinensis

[0031] 1. Temperature control during fermentation

[0032]Use EM strains to treat plant extract residues (mix EM bacteria and plant extract residues at a mass ratio of 1:10000, pile them into a strip pile with a width and height of about 1m, and control the humidity at 60% to 80 % for fermentation), the plant extract residue used in the present embodiment is the mixture of Ginkgo biloba, Radix Astragali, Codonopsis pilosula, Polygonatum ulmoides, Eucommia ulmoides, chrysanthemum and Prunella vulgaris after the active ingredients are extracted by water, and the temperature on the first day of fermentation can be When it reaches 50°C, it quickly enters the high temperature period and promotes the fermentation reaction. On the 18th day, the temperature of the material can reach 68°C, and the high temperature period lasts for 5 to 7 days, and then the temperature is slowly lowered to make the material...

Embodiment 2

[0040] Embodiment two: the nutrient substrate prepared in embodiment one is mixed with sludge as culture substrate

[0041] Domestic sludge refers to the sludge produced after the sewage treatment plant treats urban domestic sewage. In this example, the sludge produced by the sewage treatment plant in Yangling Agricultural High-tech Industry Demonstration Zone, Shaanxi Province was used.

[0042] The influence of culture medium is shown in Table 1. The quality and quantity of each group showed different degrees of growth under different proportions. Among them, the growth, development and reproduction were the best when the mass ratio of fermentation extraction residue to domestic sludge was 7:3, the penetration time was the fastest, the feed intake was the largest, the adaptability was the strongest, and the daily weight gain and daily weight ratio were the best. The multiplication factor was the largest; the ratio of 6:4 as substrate was the second; the ratio of 8:2 was th...

Embodiment 3

[0045] Embodiment three: the influence of humidity on the worm

[0046] The substrate used in this example is the substrate with the optimal ratio in Example 2, that is, the substrate with a mass ratio of fermentation extraction residue to domestic sludge of 7:3.

[0047] Substrate humidity has a great influence on the growth, development and reproduction of C. Table 2 shows the effect of different substrate humidity on the culture of worms. When the humidity is 45%, the breeding effect is the best, there is no death or escape, and the feed intake is large, the adaptability is strong, the growth and reproduction are in good condition, the range of activities is normal, and the daily weight gain and daily multiplication multiples reach the maximum. When the humidity is 40%, the effect is second. When the humidity is lower than 30% and higher than 55%, the worm escapes and dies, the adaptability becomes poor, and the daily multiplication factor decreases.

Abstract

The invention discloses a nutrient substrate for pheretima aspergillum as well as a preparation method and a culture method of the pheretima aspergillum. The nutrient substrate for the pheretima aspergillum comprises a fermented product obtained by fermentation of plant extract residues, the C / N of the fermented product is 20:(1-30):1, the organic matter content is 30%-40%, the electrical conductivity is 1754-1906S*cm<-1>, and the humidity is 30%-55%. According to the invention, a single or mixed waste residues obtained after active ingredients are extracted in a plant extraction factory are used as raw materials, and beneficial microorganisms are utilized for aerobic micro-fermentation treatment, so that the culture substrate with a suitable C / N value, enriched organic matter and suitableelectrical conductivity is obtained; and the pheretima aspergillum is cultured indoors, the culture environments are strictly controlled, the culture process is standardized, and therefore the pheretima aspergillum has robust and strong growth, high reproductive capacity, and good vitality.

Description

technical field [0001] The invention relates to a method for cultivating the hairworm ginseng, in particular to a nutrient substrate for the hairworm ginseng, a preparation method and a breeding method for the hairworm ginseng. Background technique [0002] Pheretima aspergillum (E.Perrier) is an annelid of the genus Pheretima aspergillum. Its dry body is commonly called "Pheretima aspergillum", also known as Dilong. It is a precious Chinese medicinal material. It has the effects of clearing away heat and calming convulsions, dredging collaterals, relieving asthma and diuresis. It is used for the treatment of high fever, coma, convulsions, arthralgia, numbness, hemiplegia, cough due to lung heat, edema and oliguria. Modern pharmacological studies have shown that its kinase can effectively reduce blood viscosity, inhibit platelet aggregation, and has a good therapeutic effect on cardiovascular disease, arteriosclerosis, hypertension and hyperviscosity, as well as stroke and ...
