Detailed explanation of the key technical points for courtyard greenhouse cultivation of oyster mushrooms
Using idle space in farm courtyards to build plastic film mushroom greenhouses for cultivating oyster mushrooms has the advantages of low investment, easy control of temperature and humidity, convenient management, and good returns. The main technical points are as follows: 1. Construction of the mushroom greenhouse: build the mushroom greenhouse facing south, against the west wall or east wall. The site should be slightly elevated to prevent water accumulation. Before building the greenhouse, the ground must be thoroughly cleaned to avoid garbage, weeds, and filth on the ground contaminating the environment inside the greenhouse. Use wooden posts or cement posts for support, and a bamboo pole structure is best for the roof, covered with plastic film and then with straw curtains for shade. Requirements

What technical points should be noted for indoor cultivation of oyster mushrooms?
Oyster mushrooms are welcomed by people for their delicious taste, short production cycle and ease of cultivation. Especially in Northeast China, where the climate is cold in winter and spring and fresh vegetables are scarce, growing oyster mushrooms indoors to supply the market is truly a good way to make money. However, a prominent problem in indoor cultivation of oyster mushrooms is that the air temperature is not easy to control and the surface layer of the substrate dries out easily, affecting oyster mushroom production. After repeated trials, the author believes that casing soil cultivation gives good results. 1. Mushroom house selection. Abandoned or temporarily unused houses can be chosen as the mushroom house (they must be repainted with limewater), and heating and ventilation facilities are required.

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

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 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

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

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,

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.

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
