Key Technical Points for Pollution-Free Tea Plant Cultivation and Management
I. Cultivation and Management of Tea Gardens in the Young Stage 1. Deep plowing to improve soil. Water is an important component of the tea plant organism. Deep plowing to improve the soil can store water and retain moisture, ensuring good root growth and development of tea plants. During deep plowing, do not mix up the topsoil and subsoil; place them separately in the inner side and outer trench. When backfilling, put the topsoil at the bottom of the trench and spread the subsoil on top. The depth of deep plowing must be more than 50 cm. 2. Transplanting. The transplanting time should be determined according to local conditions and varieties, generally from late February to mid-March in early spring, or from mid-October to early November in late autumn and early winter. It is advisable to choose cloudy days

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

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

Detailed Explanation of the Key Technical Points for Introducing and Cultivating Gynura segetum
Gynura segetum (Lour.) Merr. is a plant in the Asteraceae family, also known as Japanese gynura, white panax notoginseng, blood-dispersing herb, blood-dispersing elixir, blood-breaking elixir, blood peony, etc., and its traditional Chinese medicine name is tu san qi. Its tuberous roots or the whole plant are used medicinally, with effects such as promoting blood circulation, reducing swelling, detoxifying, dispersing blood stasis, and stopping bleeding. It is mainly used for traumatic injuries, carbuncles, sores, and ulcers, venomous snake bites, external bleeding, hematemesis, hematuria, hemafecia, functional uterine bleeding, and other conditions. It is mainly produced in Yunnan, Guizhou, Guangdong, Guangxi, and other places, and is rarely cultivated in the north.

Key Technical Points for Log Cultivation of Reishi Mushroom (Ganoderma lucidum) in Greenhouses
Technical Introduction: Reishi mushroom (Ganoderma lucidum) grows on broadleaf tree stumps or decaying conifer wood, forming fruiting bodies in summer and autumn. Reishi mushroom is both a saprophytic fungus and a facultative parasitic fungus. The optimum temperature for the growth of Reishi mushroom mycelium is 25°C. The optimum temperature for primordium differentiation and fruiting body development is 25-28°C. During the mycelium growth stage and fruiting body development stage of Reishi mushroom, the suitable moisture content of the substrate is 55-60%; the relative humidity of the air needs to reach 90-95%. Reishi mushroom is an aerobic fungus; when the carbon dioxide concentration in the air exceeds 0.1%, the fruiting bodies of Reishi mushroom will become deformed,

How are grafted Schisandra chinensis seedlings cultivated? A detailed explanation of the key technical points
Schisandra chinensis is a wild fruit tree distributed in Northeast China. Its fruit can be used both as medicine and for brewing wine and making juice to produce beverages. It is a multifunctional, multi-purpose wild economic plant with high development and utilization value and very broad application prospects. Since the 1990s, in response to the continuous decline of wild Schisandra chinensis resources and growing market demand, our institute has carried out research on domesticated high-yield techniques and new variety selection and breeding, summarized a complete set of domesticated high-yield cultivation techniques mainly including artificial orchard establishment, shaping and pruning, soil management, and pest and disease control, and bred a new

Methods and Technical Key Points for Preventing and Controlling Pests and Diseases of Gastrodia elata
I. Diseases are mainly infections by miscellaneous fungi such as green mold, blue mold, and Mucor. When they occur severely, they can inhibit the growth of Armillaria mellea and can also infect Gastrodia elata tubers, causing rot. Prevention and control methods: (1) Choose well-drained plots for planting; (2) Select high-quality fungal wood; (3) Control temperature and maintain moisture during cultivation; (4) Fill the gaps between fungal wood with humus soil or rice grains. II. Pests mainly include white grubs, mole crickets, golden leaf beetles, termites, rats, and damage by livestock and poultry. Prevention and control methods: (1) Light trapping to kill; (2) Use 90% trichlorfon at 1000 times or 50% phoxim at 1000 times

Detailed Explanation of Key Technical Points for Pest and Disease Control in Gastrodia elata
In recent years, we have trial-planted Gastrodia elata several times at the college and achieved a bountiful harvest, but pest and disease damage has also been common, seriously affecting the yield and quality of Gastrodia elata. The causes of their occurrence and prevention methods are described below: I. Diseases. There are mainly two categories of diseases that have a major impact on Gastrodia elata yield: one category is diseases caused by infection with harmful microorganisms, called pathogenic diseases; the other category is physiological tuber rot. 1. Soft rot of tubers. (1) Symptoms: Tubers affected by soft rot show yellowed and withered skin, with the central tissue decayed.

Methods and Technical Key Points for the Prevention and Control of Pests and Diseases in Schisandra chinensis
(1) Leaf blight starts at the leaf tip or margin in the early stage of the disease, infects the entire leaf surface, causing it to turn yellow, wither and drop; in severe cases, the fruit clusters drop. Prevention and control methods: strengthen field management and ensure good ventilation and light penetration. In the early stage of the disease, spray with 1:1:100 Bordeaux mixture, once every 7 days, for several consecutive applications. (2) Leaf roller larvae cause damage, resulting in rolled leaves, affecting fruit growth and even causing fruit drop. Prevention and control methods: use 50% phoxim 1500-fold solution or 50% phosphamidon 1500-fold solution or 40% dimethoate 1000-fold solution or 80% trichlorfon

Key technical measures for oyster mushroom production in midsummer
Oyster mushrooms are usually produced in spring, autumn and winter, but now there have also been breakthroughs in the technology for producing oyster mushrooms in midsummer. The main measures are briefly described as follows: The oyster mushroom spawn used in midsummer must be able to resist high temperatures, resist contaminating microorganisms and resist pests, and must colonize quickly and mature early. Among them, Chunqiu Tekang can resist high temperatures of 35°C; 96 Tekang and oyster mushroom 601 can resist high temperatures of 32°C; Shengming No. 1 can resist high temperatures of 33°C; Huazhong Yaping can resist high temperatures of 35°C. The mushroom-growing site must have convenient drainage and irrigation, fertile soil, a shade shed, and a clean environment. You may choose 97 kg of cottonseed hulls, 1
