Four key points to grasp in winter management of Pinellia ternata
1. Check the seed tubers: Normally, the tubers of Pinellia ternata begin to take root and sprout about half a month after planting. Sometimes, due to low temperatures, tuber rot may occur, so the growth of the seed tubers should be checked in a timely manner. For spots where sprouts have still not emerged, the soil can be gently scraped open by hand or with a bamboo strip, wooden stick, etc. Any seed tubers that have not rooted or whose rootlets are yellow-black are inferior and should be dug out and replanted in a timely manner. 2. Prevent waterlogging and drought: If continuous overcast and rainy weather occurs in winter, the soil is prone to waterlogging and oxygen deficiency, which is not only unfavorable for the tubers of Pinellia ternata to take root underground, but also causes disease and rot. Therefore,

Detailed Explanation of Key Management Techniques for Angelica sinensis During the Overwintering Period
For directly sown Angelica sinensis (Chinese angelica), in combination with topdressing before winter, cover the seedlings with manure-enriched soil or add a layer of fine soil about 1 cm thick over the seedlings to protect them from frost damage; for seedling-raised and transplanted Angelica sinensis, seedling storage work must be done well in winter; for seed-bearing Angelica sinensis, in order to improve seed yield and quality, before harvest, robust and uniform seedlings grown on high mountains or mid-mountain slopes must be selected for seed production. Afterwards, cut off the aboveground parts of the seed-bearing plants, remove all weeds, let them overwinter naturally, and keep watch frequently to prevent livestock from entering and trampling them, which would cause gaps in the seedlings. In early spring of the following year, if weeds are seen growing, they can be pulled out by hand; at this time, the root system covers the soil surface, so hoeing for weed control and fertilization must not be used, to avoid cutting the root system and hindering plant growth.

Key Techniques for Overwintering Management of Panax notoginseng Seedling Fields
Panax notoginseng is a perennial herbaceous plant. Once winter arrives, its above-ground parts all die back. At this time, the above-ground parts should be cut off 3 cm above the ground, and all dead branches, fallen leaves, diseased plants and weeds in the field should be cleared away and burned outside the field. The soil should be thoroughly sprayed and disinfected with 0.2-0.3 degrees Baume lime-sulfur mixture, and then a layer of decomposed farmyard manure should be applied at about 1500 kg per mu to keep warm and prevent freezing. If exposed roots are found, soil should be banked up when the winter fertilizer is applied, and finally a layer of grass should be spread on top to ensure the buds overwinter safely.

When should honeysuckle be newly planted? Autumn and winter are the right time
Honeysuckle can be planted in two seasons, spring, winter or late autumn, that is, between November and late March of the following year, but late autumn or early winter planting is best. To newly plant honeysuckle, the first step is to choose good land. Honeysuckle is not strict about soil and moisture conditions, and can resist drought, waterlogging and poor soil, but as a highly efficient medicinal plant, and with flower high yield as the management goal, it must be managed intensively. Research shows that honeysuckle likes sunlight and cannot tolerate shade, so sunny sandy loam with relatively deep soil layers, fertile and loose soil, good aeration and drainage, and a slope of 15

How to store Gastrodia elata seeds for safe overwintering
The seeds can be stored in a pit dug inside a cellar. First dig a pit in the cellar; the size of the pit depends on the amount of seeds, and the pit depth is 45-50 cm. The vegetative propagation stems should be removed from the seeds, and they should be air-dried for 1-2 days before being put into the cellar. Sand with a moisture content of 20% should be chosen as the filling material. Sand that is too wet or too dry is harmful to the seeds. After the pit is dug, place a layer (3 cm thick) of sand with grains ranging in size from millet to sorghum at the bottom, lay out one layer of seeds, and arrange 4-5 layers of seeds in total, with the topmost layer covered by 5-6 cm of sand. Each layer of seeds must be laid out singly, with no contact between

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

Overwintering management of Panax notoginseng, Coptis chinensis, Morinda officinalis, and Ligusticum chuanxiong
Panax notoginseng: In winter, when the leaves turn yellow and wither, cut off the above-ground stems and leaves about 3 cm above the ground, collect the dead stems and leaves, remove weeds and diseased plant residues from inside and outside the garden, and burn them all outside the garden to clean the field. Then spray the bed surface with 1:1:200 Bordeaux mixture or 0.2-0.3 degrees Baume lime-sulfur mixture to fully disinfect the soil. If exposed roots are found, add appropriate soil covering. In addition, after cleaning the garden in November, apply 2000 kg of decomposed mixed fertilizer per mu at the plant roots to protect the buds through the winter safely. Before the seedlings emerge

Key Technical Points and Methods for Gastrodia elata Management in Winter and Spring
After November, as temperatures gradually drop, the new Gastrodia elata tubers stop growing, their size becomes fixed, and they enter dormancy directly, so low-temperature freezing damage should be prevented. In particular, the arrow tubers (Jianma) are easily damaged by freezing during overwintering. It is best to use arrow tubers for medicinal purposes when harvesting Gastrodia elata in winter, and to sow or store the small tubers (Mima) and white tubers (Baima) in time for spring planting. If they are not harvested in winter, cold-protection measures must be taken before freezing, such as covering with tree leaves to keep warm and prevent freezing, and removing them the following spring to facilitate growth. The temperature should be maintained at 1-5°C, and the humidity should be maintained at 30%.

What effect does low winter temperature have on Gastrodia elata
The tubers of Gastrodia elata are buried underground and overwinter in a dormant state; the stable low temperature they can tolerate is 0-5°C. However, if winter temperatures fluctuate frequently, with large swings in temperature difference, sudden warmth followed by sudden cold, Gastrodia elata is prone to cold damage. Therefore, special attention should be paid to cold protection and heat preservation for overwintering Gastrodia elata, especially for box-cultivated Gastrodia elata, which should be covered even more carefully to preserve warmth and prevent cold damage. But Gastrodia elata has a certain low-temperature cycle and requires an appropriate stable low temperature in winter, otherwise its sprouting will be adversely affected.
