Harvesting and Processing Methods of Panax notoginseng and Key Technical Points
Harvesting can be done after more than three years of cultivation. Harvesting is divided into two periods: Panax notoginseng harvested in July-August is called "spring notoginseng," and the notoginseng harvested after the flower stalks are removed has the best quality and also high yield; Panax notoginseng harvested from December after the Beginning of Winter to January of the following year is called "winter notoginseng," which has poorer quality and also low yield. After digging out, remove the aboveground stems and wash off the soil. After cutting off the rhizome (sheep intestine head), branch roots, and removing the fibrous roots, it is called "touzi." Repeatedly sun-dry and rub the touzi to make it firm until completely dry, which is "maohuo." Then

How to sow Panax notoginseng? Detailed explanation of sowing methods and technical key points
Sowing rate of Panax notoginseng per mu: with a row spacing of 7 cm x 7 cm, about 75,000 to 90,000 seeds; with 10 cm x 7 cm, about 50,000 to 60,000 seeds; with 10 cm x 10 cm, about 33,000 to 40,000 seeds; the land utilization area is 50% to 60%. The sowing period is from early to late November, and no later than January of the following year. Before sowing, first make a hole-punching template from wood, that is, on a wooden board 1.3 to 1.5 m long and about 30 cm wide, fix several round

Introduction to the methods of germination and sowing of Gastrodia mushroom spawn
1. Types of germination fungi The germination fungi of Gastrodia seeds reported so far all belong to 4 species of fungi in the Tricholomataceae family, Mycena genus. Their names are: first, Mycena osmarioides; second, Mycena orchidicola; third, Mycena dendrobii; fourth, Mycena anoectochila. In 1999, we isolated and cultured another type of fungus for Gastrodia seed germination, which is Trametes lactinea of the Polyporaceae family. This fungus is superior to the above four fungi in production and application during the higher temperature season. 2. Production technology of germination fungi Isolation and culture of the mother spawn of germination fungi: in Gastrodia cultivation sites

Symptom Identification and Control Methods for Licorice Gray Leaf Spot
It damages the leaves, forming nearly round brown lesions with gray centers. Control methods: (1) Clear the garden in winter and dispose of plant debris. (2) During the disease period, spray 1:1:120 Bordeaux mixture or 70% thiophanate-methyl wettable powder at 1500-2000 times dilution.

Pinellia ternata pest and disease control methods and key technical points
(1) Root rot: This disease is prone to occur in hot seasons when water accumulates in the field. After onset, the underground tubers rot, and the aboveground parts then collapse and die. Control methods mainly focus on drainage, removing diseased plants and treating the diseased holes with 5% lime water or pouring it on the roots; alternatively, soak seeds in 0.5%-2% lime water for 12-30 hours at sowing time. (2) Viral disease: Manifested as leaf curling and mosaic, mostly occurring in spring and summer. After onset, diseased plants should be pulled up and burned, and the area disinfected with lime. (3) Red hawk moth: With

Identification and Control Methods for White Grub Infestation in Codonopsis pilosula
Belonging to the order Coleoptera, family Scarabaeidae. It is the larva of the scarab beetle, mainly active in the soil, damaging the roots of Codonopsis pilosula. White grubs generally have one generation per year, with larvae or adults overwintering in the soil. After temperatures rise in the following spring, white grubs gradually move upward in the soil; when the soil temperature reaches above 15°C, they move into the topsoil layer above 10cm to feed. When summer temperatures rise and the soil dries out, they descend to deeper soil layers and stop feeding or moving. In autumn they return to the topsoil layer to be active, and after October they successively burrow down below 30cm to overwinter.

Control Methods for Red Spider Mite Infestation on Codonopsis pilosula
Belongs to the class Arachnida, order Acarina, family Tetranychidae. Adults and nymphs gather in groups on the undersides of leaves to suck sap, and spin silk webbing, damaging leaves and tender shoots, causing leaves to turn yellow and eventually drop off; after flowers and fruits are damaged, they become shrunken and withered, spreading rapidly with severe damage, being most serious during dry autumn weather. Control methods: clear the garden in winter, pick up all dead branches and fallen leaves, and burn them in a centralized manner; after clearing the garden, spray 1-2°Bé (1-2 Baume degrees) lime sulfur mixture; in spring spray 0.2-0.3°Bé (0.2-0.3 Baume degrees) lime sulfur

What are the pest and disease control methods for Codonopsis pilosula?
Codonopsis pilosula is a commonly used traditional Chinese medicine. It is widely cultivated in northern China, and its roots are used medicinally. It has functions such as tonifying qi and nourishing blood, harmonizing the spleen and stomach, and promoting fluid production and clearing the lungs. It is mainly used to treat various qi deficiency conditions such as shortness of breath and weakness, thirst due to fluid damage, weakness of the spleen and stomach, loss of appetite, loose and watery stools, cough and asthma due to lung deficiency, weakness after febrile disease, and prolapse of the anus due to qi deficiency. It has a very wide range of uses. The pest and disease control methods are introduced as follows: 1. Root rot often begins to occur during the high-temperature and high-humidity period from May to June in summer. It mainly occurs in Codonopsis pilosula plants that have been growing for more than 2 years. In the early stage of the disease, the lateral roots near the ground

Detailed Explanation of Methods and Techniques for Angelica Pest and Disease Control
Root rot: Soak seedlings in 1:1:150 Bordeaux mixture, disinfect and insecticide-treat the soil: burn and fumigate the soil more in seedling beds. Brown spot: Pay attention to field sanitation, promptly remove diseased leaves, and in the middle and late stages spray 1:1:150 Bordeaux mixture once every 7 days. Pests: Mainly green peach aphid, commonly known as "oil worm." It multiplies in large numbers during May, densely gathering on the undersides of leaves of new shoots and tender leaves of angelica to suck sap, causing heart leaves and tender leaves to thicken, curl into a fist-like shape, and the plant to become stunted. Control methods: Clear weeds around the field to reduce opportunities for aphid migration; when aphids occur
