Three key steps for storing Gastrodia elata properly
Recently, I have received letters from many farmer friends asking how to store Gastrodia elata seed tubers. During the production of Gastrodia elata, seed rot often occurs, causing losses. In my opinion, three key steps should be taken when storing Gastrodia elata. First, the harvest step. Gastrodia elata is dug in spring and winter. When digging Gastrodia elata in winter, select fresh, pest-free, undamaged small tubers, air-dry them for 1-2 days to remove part of the moisture, and then store them together for use as seed the following year. Second, the temperature step. Place the partially air-dried Gastrodia elata seed tubers in layers in a brick pond, a large earthen basin or a wooden box

What are the three key points for storing Gastrodia elata seeds in winter?
1. Harvesting. From late October to the end of November, while harvesting commercial Gastrodia elata, also harvest the tuberous root seeds. Select fresh, pest- and disease-free, undamaged small white Gastrodia tubers, air-dry them for 1-2 days to remove some moisture, then gather and store them for use as seeds the following year. 2. Temperature. Place the Gastrodia tubers, after some moisture has been air-dried off, in layers inside a wooden box, brick pit, or large earthen basin. Cover each layer with moist sandy soil. First spread a base layer of yellow sand, then place a layer of Gastrodia seeds on top, and repeat this for 4-5 layers. The storage temperature should be kept at 2-5°C. Do not let the temperature

Three key points to master for high-yield Gastrodia elata cultivation
I. Armillaria must be "three new" 1. New technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify the strains, which is by far the most advanced method of obtaining strains. Among traditional Armillaria strains, the best results come from those obtained by tissue isolation or spore isolation; most units or individuals use purchased mother cultures for subculturing and expansion, so the cultivation results are poor. 2. New strains: pure isolated strains within three generations are required. The pure isolated strains referred to in this article mean

Three key points for high-yield cultivation of Gastrodia elata
In recent years, as the area devoted to Gastrodia elata production has shrunk sharply while market demand keeps rising, the price of Gastrodia elata has shown a continuously upward trend. Recently many growers have called to inquire about cultivation techniques for Gastrodia elata. A reporter interviewed Gastrodia elata expert Professor Cao Debin of the Shandong Academy of Agricultural Sciences on this topic. The key points of high-yield cultivation techniques for Gastrodia elata are introduced here, in the hope of being helpful to the many Gastrodia elata growers. 1. Armillaria must be "three new" 1. New technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify the strains, and this is by far the most advanced method of obtaining strains.

Key Points of Three-Dimensional Cultivation Technology for Gastrodia elata and Soybean
Gastrodia elata is a traditional Chinese medicinal herb with effects such as benefiting qi, calming convulsions, nourishing the liver and stopping dizziness, dispelling wind-dampness, and strengthening bones and muscles. In recent years, on the basis of artificial box cultivation, we have made full use of the growth characteristics of Gastrodia elata and successfully adopted underground planting of Gastrodia elata with above-ground planting of the short-stalked crop soybean. According to investigation and measurement by the Agricultural Station of Shuidian Town, in three-dimensional cultivation of soybean and Gastrodia elata, the yield of commercial dried Gastrodia elata is 200-300 kg per mu, creating an output value of 8000-10000 yuan (calculated at 36-40 yuan/kg); the yield of soybean is 150-175 kg per mu, creating an output value of 360-

How to Increase Gastrodia elata Yield? The Three-Switch Measures Are Key
Gastrodia elata is a fine medicinal herb and has been selling well in the market in recent years. The farmers of Chalu Village, Baoshan Town, Fengcheng City, Liaoning Province, regard developing Gastrodia elata production as an important path to wealth; more than 40 households in the village grow Gastrodia elata and earn considerable income every year. Li Jingrong, a retired cadre of the village, has grown Gastrodia elata for 14 consecutive years and accumulated rich experience. He found that the yield of artificially cultivated Gastrodia elata tends to decline year by year. There are mainly 3 reasons: first, because self-bred and self-propagated tuber seeds are used year after year, the degeneration is severe; second, because self-bred and self-propagated fungal strains are used year after year,

Key Points on Harvesting and Processing Techniques for Licorice (Part Three)
For licorice propagated from seed, harvest in the 4th year; for licorice propagated from rhizomes, harvest in the 3rd year. Harvesting can be done either before Grain in Ear (Mangzhong) or after White Dew (Bailu), but harvesting after White Dew is preferable. After digging them up, cut off the branches and twigs while fresh, sun-dry until half dry, tie into small bundles separately according to thickness, and sun-dry until completely dry. Quality specifications for dry goods: cylindrical in shape, thick at the top and thin at the bottom with no reed head, surface purplish-red or grayish-brown, rough skin, loose and light in texture, cross-section yellow-white, starchy, sweet in taste, free from impurities, insect damage, and mildew. Grade One: length over 60 cm, diameter over 1

Detailed Explanation of the Biological Characteristics of Angelica sinensis (Part Three)
(1) Bolting and flowering. Angelica sinensis is a monocarpic plant. Under normal cultivation conditions, it enters the bolting and flowering stage in the third year. About half a month after the plant turns green again, the growing point begins to shift from the vegetative growth state to the reproductive growth state, forming a reproductive growing point, and some protrusions gradually appear at its apex, namely the inflorescence primordia. As the inflorescence primordia elongate and grow, the tip of each primordium begins to widen and produces several small protrusions, namely the umbellule primordia. After the umbellule primordia elongate, they form the rudiment of a compound umbel. At the same time, the basal stem swells and lengthens, forming internodes and constituting

Detailed Explanation of Key Techniques for Cultivating Lingzhi with Three Harvests a Year
Lingzhi is a medicinal fungus. With the development of modern medicine, its medicinal value is continuously being discovered, and thus artificial cultivation has attracted widespread attention. Its high-yield cultivation techniques are neither as complex as some people think nor as simple as some people think. As long as appropriate technical measures are taken, achieving high yields is still hopeful. From years of practice, to achieve three harvests a year, the following points generally need to be mastered: 1. Reasonably arrange the production season. Lingzhi is a high-temperature, constant-temperature fruiting fungus. During its growth and development process, it needs

What is the annual yield per mu of Pinellia ternata with three plantings and three harvests?
If Pinellia ternata is propagated from tubers, hotbeds or electrically heated hotbeds should be used to sprout them. In early March, that is, between Yushui (Rain Water) and Jingzhe (Awakening of Insects), when the 5 cm soil temperature is stable at 8-10°C, it can be sown, and in the same year or the following year in mid-June, between Mangzhong (Grain in Ear) and Xiazhi (Summer Solstice), it can be dug up without affecting summer-sown autumn crops. Pinellia ternata generally yields 600-800 kg/mu of fresh tubers, with a drying ratio of 25%-30%, which can be converted to 180-240 kg/mu of dried product.
