Ingredients: 30g of Cordyceps sinensis, 250g of tortoise and 90g of Glehnia littoralis.
Seasoning: salt 3g, monosodium glutamate 2g.
Steps:
1. Put the soft-shelled turtle in a small pot and heat water (about 40 degrees) to make it defecate.
2. Slaughter the head and feet of the soft-shelled turtle, remove the shell and viscera, and wash them with clear water for 2 to 3 times.
3. Soak Cordyceps sinensis and Adenophora adenophora in warm water for 20 minutes, then wash them with clear water, put them in a stew with soft-shelled turtle, add a proper amount of boiling water, and stew them with slow fire until the nail fish is cooked.
Cordyceps sinensis is a complex of cordyceps sinensis and hepialidae larvae.
Cordyceps sinensis is a perennial herb with a height of 40 to 50 mm; Rhizomes are transverse, fleshy, and fibrous fibrous fibrous roots are produced at nodes. The stem is erect, quadrangular, with four grooves, and sparsely pilose bristles on the edges and nodes. The stems and leaves are oblong and ovoid, 4.5-8 cm long and 2.5-3 cm wide, with obtuse top, shallow heart-shaped or round base, neat and thick thin round serrations at the edge, green top, fluffy bristles scattered at the bottom, light color at the bottom, densely covered by other main veins, about 4 pairs of lateral veins, inconspicuous top, prominent bottom and long petiole1-4. Bracts become smaller, and the last pair of bracts are the same shape as stems and leaves, smaller, needle-like and ovoid, blunt at the top, round at the base, short or subsessile at the stalk, small at the upper part, rhombic-lanceolate, usually shorter than calyx, undulate at the edge and sessile. Cymes axillary, 4-6-flowered, far away, forming spikes, 5- 18 cm long; Bracts are few, linear subulate, tiny, less than 0.5 mm long, caducous; Pedicel is about 65438 0 mm long and puberulent. Calyx is obconical, small, with teeth 5.5mm long, densely puberulent on the outside and glandular puberulent on the inside, with obvious veins 10, and secondary veins more or less obvious at the base of calyx. Calyx tube is 4 mm long, with 5 teeth, regular triangle, equal size, 65438 0.5 mm long, glandular puberulent at the edge and scabbed at the top. Corolla purple blue or reddish, about 1. 1 cm long, crown tube about 7 mm long, cylindrical, equal thickness. The outside of the top is puberulent, and the rest is glabrous. Near the inside of the base 1/3, there is a horizontal puberulent ring, with a 2-lipped crown, a straight upper lip, an oval shape and a length of 4 mm. 4 mm wide, puberulent outside, puberulent inside the middle, 3-lobed, with the largest middle lobe, rectangular, 65438 0.5 mm wide, and the lateral lobes oval, about 65438 0.5 mm wide. Stamens 4, the front pair slightly longer, all rising below the upper lip, filaments filiform, puberulent below the middle, anthers ovoid, 2-loculed, locules slightly bifurcated, and the back pole bifurcated. Style filiform, slightly beyond stamens, apex equal to 2-lobed. Disk cup-shaped. Ovary dark brown, glabrous. The flowering period is from April to May.
The artificial domestication and cultivation of Cordyceps sinensis is mainly to prepare strains and insects.
(1) strains: Cordyceps cultivation should first have excellent pure strains. First, it should be early-maturing and high-yielding, with the main purpose of shortening the production cycle and reducing costs. Second, it should be contagious, requiring the strain to have strong vitality and a survival rate of over 95%, which can quickly infect insects and get sick and die as soon as possible; Third, it has a wide range of application, especially for miscellaneous bacterial infections such as environmental temperature changes.
(2) Insects: moth larvae are mainly used as parasites of Cordyceps sinensis. Larvae must be alive, large and obese, and the number depends on their own breeding. Generally, it needs 1 kg larva, 1 parent species, and 50kg fine sand per square meter.
(3) Environment: Cordyceps sinensis can be cultivated artificially regardless of altitude, and the key depends on temperature. Cordyceps sinensis is a medium-low temperature fungus. The temperature of mycelium growth and reproduction is 5-32℃, the optimum temperature is 12- 18℃, and the optimum temperature for sclerotia and daughter formation is 10-25℃.
(4) Cultivation season: Natural temperature can be used to cultivate two seasons a year, namely, March-May in spring and 9- 165438+ 10 in autumn. If the indoor temperature is controlled, it can be cultivated all year round and the growing period can be shortened.
