Detailed Explanation of Angelica sinensis Harvesting and Processing Techniques (Part 3)
For autumn direct-seeded plants, harvest in the second year; for transplanted plants, harvest in late October of the same year, when the plants turn yellow and withered. Dig up the whole plant, shake off the mud and sand, and air-dry for 2-3 days until the roots become soft. Then remove the stems, leaves and fibrous roots, sort them by root size, tie them into small bundles, hang them head-down on the curing rack, and smoke and roast them slowly with smoke and fire. During smoking, pay attention to indoor ventilation and turn them frequently. After drying, rub off the fine hairs and fibrous roots, and they are ready as a commercial product. Generally, 667 sq m can produce about 150 kg of dried product. High-yield fields can reach 400 kg.

Key Harvesting and Processing Techniques for Angelica sinensis (Danggui) (Part One)
(1) Harvesting For direct-sown plants, dig in mid-to-late October of the second year; for seedlings raised in a nursery and then transplanted, dig in mid-to-late October of the same year, when the plants have withered and turned yellow. Digging too early results in roots that are not plump and solid, with low yield and poor quality; digging too late means the soil has already frozen, making digging difficult and prone to breaking the roots. Before harvesting, first cut off the above-ground stems and leaves and sun-dry them for 3-5 days, so that the roots become fuller and more solid; then carefully dig out the entire root. (2) Processing After harvesting, angelica sinensis must not be piled up. First clean off the soil, choose a high, dry, well-ventilated spot, spread the roots out to dry until the roots become soft, or sort them

Origin Processing Methods and Technical Key Points for Angelica sinensis
The processing of Angelica sinensis directly affects the quality and medicinal efficacy. Because fresh Angelica sinensis contains more than 60% water and the medicinal component volatile oil, if processing is not timely or not done well, it will become moldy and deteriorate. Processing methods and procedures for Angelica sinensis: 1. Sorting and bundling. The recovered Angelica sinensis should be sorted promptly, and roots that are rotten, especially water-rotted, should be picked out to prevent the spread and infection of water rot. The selected Angelica sinensis is spread under the eaves in a dry, ventilated place to air-dry for about 7 days so that the moisture evaporates and the roots become soft, then they are bundled with willow twigs or tree bark. Each bundle of fresh

What are the processing methods for Angelica sinensis? Read this article to find out
After harvesting, shake off the soil, pick out the rotten roots, remove the remaining leaf stalks, and after the moisture has slightly evaporated, tie them into flat bundles weighing 0.5~1 kg and place them in a smoking shed. Inside the smoking shed, build a 130 cm high rack, lay bamboo strips on top, and place the angelica bundles on it alternately flat and upright, with a thickness of 30~50 cm. Use soybean stalks, wet poplar, willow wood, etc. as fuel; after lighting, spray water so that it only produces smoke and no open flame, smoke them to color, until the surface of the angelica turns reddish red, then switch to coal fire or firewood (grass) fire and smoke for about 10 days, then turn over

A Detailed Explanation of the Processing Methods and Key Technical Points for Angelica sinensis
The pharmacological effects of Angelica sinensis (dong quai) are very broad, and it is an extremely commonly used traditional Chinese medicine. Therefore, it is often made into different decoction pieces for use. The common decoction pieces mainly include "whole dong quai," "dong quai body," "dong quai tail," "stir-fried dong quai," "dong quai charcoal," "oil-stir-fried dong quai," "wine-stir-fried dong quai," and so on. They are described separately below. (1) Whole dong quai: take the raw Angelica sinensis medicinal material, remove impurities, wash clean, pile and moisten until thoroughly penetrated, cut into thin slices, and dry in the shade or at low temperature. (2) Dong quai body: wash the dong quai body clean with water, moisten until

Detailed Explanation of the Harvesting and Processing Methods and Uses of Lingzhi (Reishi Mushroom)
Harvesting and Processing: Lingzhi generally requires 50-60 days from inoculation to harvest. When the edge of the cap stops growing and brownish-red basidiospores appear on the hymenium beneath the cap, it indicates that the fruiting body has matured, and it can then be harvested. Cut it off from the middle of the stipe with a small knife, taking care not to crack the cut surface, then spread it out to air-dry or dry it at low temperature. If collecting spore powder, place clean plastic sheeting or smooth, clean paper under the fruiting bodies on the cultivation rack, collect with a bristle brush, and after the spore powder has been sun-dried and dried, store it in plastic bags for medicinal use. Uses:

Detailed Explanation of Key Technical Points for Ganoderma Harvesting and Processing
1. Harvesting and drying. Under normal conditions, it takes about 20 days from the appearance of the primordium to the maturation of the cap. When the cap is fully expanded, releasing a large number of spores, the white edge has disappeared, the thickening is not obvious, and the cap color is crimson red (red Ganoderma), with uniform color, it can be harvested. After harvesting, promptly cut off the culture medium adhering to the base of the stipe from the fruiting body, dry it in sunlight, or place it in a drying room for drying, with the temperature controlled at 55-65°C, until the moisture content of Ganoderma is about 12%. The moisture content of fresh Ganoderma is usually 63%, and the drying ratio is generally 40%-

Processing Methods and Storage Tips for Scorpions
In the process of artificial scorpion farming, timely harvesting, processing, storage and selling are important steps for making full use of space, saving feed, speeding up capital turnover and increasing added value; this work should be carried out 7 days before pregnant scorpions give birth, by keeping strong pregnant scorpions and high-quality breeding scorpions, and harvesting and processing the remaining mated male scorpions, female scorpions that have given birth for more than 3 years, and some scorpions with missing limbs, disease or weakness as commercial scorpions. 1 Processing methods 1.1 Processing of "salted whole scorpions" Before processing, first put the scorpions into cold

What are the patterns of silkworms spinning silk and forming cocoons? A full explanation of the process
The life of a silkworm goes through 4 stages: egg, larva, pupa and adult. The larval stage of the silkworm is what people call the silkworm baby stage. What is usually called sericulture refers to the rearing of the larvae. From hatching to cocoon spinning, the larva must go through 4 molts. People therefore divide the course of the larva into 5 instars. During the period before molting, the silkworm does not eat or move, which is called sleeping. From the first to the fourth instar, the silkworm must sleep 4 times; in the later stage of the fifth instar, it no longer sleeps, but spins silk and forms a cocoon, and pupates inside the cocoon, thereby completing the larval stage of the silkworm. Newly hatched silkworms are called ant silkworms, and newly molted
