Detailed Explanation of Key Points in Gastrodia elata Harvesting and Primary Processing
If Gastrodia elata is sold fresh, it is enough to keep it from being bumped, dropped, or mechanically damaged after harvest, then gently brush off the mud and sand on the tubers with a soft brush and pack them into soft-lined wooden boxes or plastic crates. If processing dried Gastrodia elata, the method is more complicated: generally, it is first cooked by boiling in water or steaming in a steamer basket, and then dried by oven or sun. In actual production, the method of steaming in a steamer basket and drying in a kang oven is generally used, and the operational process is: grading - washing - steaming - kang drying. 1. Grading: grade by 50-gram differences according to the weight of Gastrodia elata, that is, place and process separately those below 50 grams, 50-99 grams, 100-150 grams, 151-200 grams, and 201 grams and above, while removing diseased tubers, rotten tubers, and other unqualified products.

Detailed Explanation of Gastrodia Harvest Season and Processing Methods
Sexual reproduction: sow in June and July, harvest in November of the following year. Asexual reproduction: winter sowing, harvest in November of the following year; spring sowing, harvest in November of the same year or spring of the following year. After digging and harvesting, the large ones are used for medicinal purposes, and the small ones are kept as seed tubers. For medicinal gastrodia, wash off the soil, divide into 2 to 3 grades, put into water (add a little alum), boil the large ones for 10 to 15 min and the small ones for 5 to 10 min, judging by whether they are cooked through; when viewed from a dark place toward a bright place, if there is no black core and they are translucent, they are fully cooked. Then fumigate with sulfur for 20 to

What are the processing steps for Gastrodia elata? A clear explanation of every step at once
If Gastrodia elata is piled up for a long time after harvest, it will rot, so Gastrodia elata should be processed promptly after harvest. Its processing steps are as follows: 1. Grading. According to the size of Gastrodia elata, it can be divided into 3 grades. Those above 150 grams are first-grade products, 75-150 grams are second-grade products, and those below 75 grams and those damaged during digging are third-grade products. 2. Washing off soil. Wash the above 3 grades of Gastrodia elata separately with clean water. The washed Gastrodia elata must be processed the same day. If soaked in water overnight, the processed Gastrodia elata will be black, which will affect its medicinal use

How to do simple processing of Gastrodia elata? Detailed method and steps
In the processing of Gastrodia elata, the residual stems must first be removed, taking care to keep the arrow buds, wash off the mud and sand, rub off the rhizomorphs and scales, wash clean with clear water, and then steam in a steamer. The heat must be strong and the steamer lid must be tight, so as to quickly kill the cells of the tuber, inhibit enzyme activity in the tuber, and prevent the leakage of sap. Steam large tubers for 30 minutes and small tubers for 15 minutes, until thoroughly cooked (no white core). If any are excessively swollen with gas, pierce them with a raw needle to release the gas, then place them on a heated kang or in a drying room, or sun-dry them. Generally, 4-5 kg of fresh Gastrodia elata is needed to process 1 kg of finished product. 1. Fire

A Detailed Guide to Artificial Cultivation Techniques and Processing Methods for Gastrodia elata
Gastrodia elata is a parasitic herb. Its underground tuber is an important medicinal material, in great demand on both domestic and international markets. In recent years, the price of Gastrodia elata has remained firm, holding steady at 260-300 yuan per kilogram. In the past, Gastrodia elata was produced by vegetative propagation; because there was little planting stock of Gastrodia elata and it degenerated easily, both yield and quality could not meet demand, and it was in very short supply. Since last autumn, the market has turned brisk and prices have risen. The market transaction price for domestically grown first-grade Gastrodia elata is 280 yuan per kilogram, close to the historical high. The reasons are the social [market conditions], a sharp surge in demand, a decline in output, and an improvement in the export situation.

Detailed Explanation of Gastrodia elata Cultivation Techniques and Processing Methods
Gastrodia elata is a herbaceous plant, with its underground tubers used as medicine. It mainly treats high blood pressure, dizziness, headache, facial paralysis, limb numbness, infantile convulsions, hemiplegia and other conditions. It is also used for pilots' brain health care and Alzheimer's disease, etc., and is an ideal medicine for brain and nerve health. 1. Propagation of Gastrodia elata 1.1 Sexual propagation When a few Gastrodia elata plants send up aboveground stems and bloom, the sandy soil should be kept moist, the flowering stems fixed with bamboo poles, and direct sunlight shaded. After the flower buds take shape, the flowers open from bottom to top, one to several per day. If pollinating insects are lacking, @#@255@#@ can be kept nearby or artificial pollination can be carried out: use tweezers to open the corolla, remove the anther cap, take out the pollen mass, and place it on the stigma. Pollination should be done between 10 a.m. and 4 p.m. If pollination is successful, the ovary swells, the corolla withers, and the ovary suture becomes obvious. Once it splits, a large number of seeds will be released. When one fruit splits, cut off 3-5 adjacent fruits and place them in a container to take the seeds after they split naturally. The seeds scattered in the container should be sown immediately and must not be left standing. Lift up the cultured fungal material of the prepared fungal bed, spread broadleaf tree leaves about 1 cm thick underneath, scatter the seeds among the leaf layer, sowing the seeds of 10-20 fruits per square meter, then restore the fungal material to its original state, scatter a layer of leaves, cover with fill, and let it grow strong Gastrodia elata, becoming a high-yielding hybrid seed tuber. When planting Gastrodia elata, make several more fungal beds, do not put in seed tubers, and prepare them for use in sexual propagation of Gastrodia elata.

Detailed Explanation of Fine Processing Methods and Technical Points for Gastrodia elata
Gastrodia elata must be processed as soon as it is dug up and harvested, because if stored for too long, it easily loses its sap, reducing the drying ratio. Spring-harvested Gastrodia elata especially cannot be stored. Spring temperatures are high, and if it is not processed in time, it will also become moldy and rot. During processing, first wash the dug-up Gastrodia elata clean of soil with clean water, then wipe off the moisture with a cloth, and then put it in a pot to stir-fry together with fine sand. According to the size of the pot (No. 1 or No. 2 pot), put fine sand in each pot for stir-frying. According to the size of the pot (No. 1 or No. 2 pot), put 4-7.5 kg of fine sand in each pot and 1.5-2.5 kg of Gastrodia elata. It should be processed according to

How is honeysuckle processed? A detailed explanation of processing methods
The processing of honeysuckle includes rough processing and fine processing (deep processing), etc. Here we focus on rough processing. (1) Sulfur fumigation: After removing branches, leaves and impurities from the harvested honeysuckle, it can be fumigated. For a small amount of flowers, small wooden cabinets, water vats, rice steaming baskets, etc. can be used for fumigation; for a large amount of flowers (over 200 jin), a sulfur fumigation pool can be built for fumigation. Two to three layers can be set up inside the pool, with each layer 40 cm apart, and bamboo mats laid on them. Then spread the honeysuckle on the bamboo mats (be careful not to press the honeysuckle tightly), and each layer should have two ventilation holes. Each layer should be covered with burlap

Detailed Introduction to Honeysuckle Processing Techniques
There are 2 processing methods: air-drying and oven-drying. (1) Sun-drying. Before 1970, producers in Shandong generally chose a wind-sheltered, sunny flat surface or stone slab with long sunlight exposure, spread a thin layer of flowers in the morning, and dried and collected them the same day. This method saves labor and time, but windy days and rainy or overcast weather affect quality. Since 1970, the basket-drying method has been used more often. A basket frame about 1.7 m long, about 0.7 m wide and 5-7 cm high is made from wooden rods, with a base of sorghum stalks or a mat (sorghum stalks are not peeled; the mat should be turned over to absorb water better). Each basket dries 2
