Detailed Explanation of Key Points for Intercropping Cultivation Techniques of Gastrodia elata
1. Intercropping time. Intercropping Gastrodia elata in tree peony root bark fields should be carried out from late autumn after the tree peony leaves fall to early spring of the following year. This is both the dormant period of the tree peony and the harvest period and optimal planting period of Gastrodia elata. 2. Intercropping method. For tree peony root bark plots used for intercropping Gastrodia elata, choose plots where tree peonies have been planted for more than 1 year. First, prepare Armillaria fungus wood and Gastrodia elata seeds, and also prepare enough leaves for use as filler and mulch, then plant according to the conventional planting method for Gastrodia elata. When planting, first spread a layer of leaves between the rows of the tree peony root bark field, with a thickness of 5 cm to 10 cm

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%.

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

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

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

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

Intercropping Cultivation Techniques for Licorice in Land Returned from Farmland to Forest
Intercropping licorice in land returned from farmland to forest can both conserve soil and water and increase economic returns, achieving the goal of using the land to support the forest and the forest to support the land, and realizing a "win-win" for both the economy and ecology. Since 2002, Regiment 137 has conducted cultivation trials of intercropping licorice in land returned from farmland. After several years of experimentation and exploration, breakthrough progress has been made. 1. Land selection: Select sandy loam plots of land returned from farmland to forest with relatively low salinity and alkalinity, relatively few field weeds, and good drainage for intercropping licorice. The main tree species planted in the sowing area is wolfberry seedlings; the planting pattern is furrow planting

How to do intertillage and weeding for licorice? Practical methods and technical key points
Licorice is suitable for growing on idle beach and vacant land where crops cannot be planted, and such land tends to have many weeds as long as there is water, and the success or failure of planting and the level of yield are all related to weeding. When there are many weeds, the utilization rate of water and fertilizer by licorice is low, and the yield naturally decreases. For licorice fields planted in large fields, weeding should be carried out by combining manual weeding and chemical herbicide weeding. That is, in the year of planting, manual weeding is mainly used; starting from the second year, for plots with many weeds, select appropriate herbicides in June to July for chemical weeding, hoe and till once before the rainy season, and till once again after autumn.

Under full-light cultivation of Schisandra chinensis, Welsh onion or Schisandra chinensis seedlings can be intercropped
To make full use of the land between the rows of cultivated Schisandra chinensis, before the Schisandra chinensis plants reach fruit-bearing at 4 years of age, intercropping Welsh onion or Schisandra chinensis seedlings can yield certain economic benefits to offset the costs of cultivating Schisandra chinensis. I. Planning 1. When Schisandra chinensis is cultivated with a row spacing of 1.5 m and a plant spacing of 0.5 m, the available inter-row land area per mu (667 sq m) of Schisandra chinensis orchard is as follows: for each mu (667 sq m) of land, estimated by a long side of 33 m and a short side of 20 m (660 sq m), with a row spacing of 1.5 m, 22 rows can be laid out, each 20 m long; at the early stage of cultivation, the horizontal spread of the Schisandra chinensis root system is not large, so the width of the Schisandra chinensis seedling belt can be kept at 80 cm (40 cm on each side), the usable inter-row width is 70 cm, leaving a ditch width of 10 cm on each side, and one ridge 50 cm wide can be formed, on which 2 rows of Welsh onion are planted, with a row spacing of 10-15 cm and a plant spacing of 10 cm. Based on this calculation, each inter-row space can plant 10 sq m of Welsh onion, and each mu of Schisandra chinensis orchard can plant 22 rows of Welsh onion, requiring 9,680 Welsh onion sets; each Welsh onion set is 1.5-2 cm in diameter, about 80 per jin, so about 120 jin of Welsh onion sets are needed, and the plantable Welsh onion area is 220 sq m.

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.
