Common Disease Prevention and Treatment Methods and Key Technical Points for Fish and Crabs
I. Grass carp hemorrhagic disease. Symptoms: bleeding in the fins, mouth cavity, eye sockets, muscles, and intestines, partially or entirely bright red. Prevention and treatment: 1. Broadcast dibromohydantoin or chlorine dioxide over the entire pond, using 200 grams of dibromohydantoin or chlorine dioxide per 1 mu of water surface at a depth of 1 m. Apply once more after 2-3 days. 2. Mix into bait and feed Yu'erkang, mixing 1 kg of Yu'erkang per 50 kg of feed, and feed continuously for three days. 3. Mix into bait and feed Suke, mixing 50 grams of Suke per 50 kg of feed, feeding once a day for three days as one treatment course. If combined with external application of dibromohydantoin,

Key Technical Points for Feeding and Management of Foie Gras Geese During the Pre-feeding Period
Geese of around 12 weeks of age should be selected for foie gras production. At this time, the number of liver cells in geese is relatively high, and the activity of fat-synthesizing enzymes in the liver is relatively strong, which is beneficial for rapid liver weight gain. Before 2 weeks of age, goslings are mainly raised with roughage and grazing to reduce feeding costs. The pre-feeding period is the transition from grazing to housed feeding, and from roughage to concentrate feeding. The quality of feeding during the pre-feeding period directly affects the production results of foie gras. The key to feeding during the pre-feeding period is to let the geese have a gradual adaptation process, so that they adapt to a high-nutrition diet and adapt to a large amount of concentrate feed.

Prevention and Control Methods and Technical Key Points for Goose Influenza
This disease is a widespread acute, respiratory and septicemic infectious disease, occurring mainly in winter and spring. Goslings weighing around 500 g are most susceptible (adult geese are less commonly affected), and in severe cases the morbidity and mortality rates reach 80-90%. Sudden climate changes, excessive temperature differences in the goose house, long-distance transport and poor feeding management can all lead to the occurrence of this disease. The disease is transmitted mainly through the respiratory tract, and contaminated feed and drinking water can also spread it. 1. Symptoms The main feature of sick geese is difficulty breathing, with large amounts of serous discharge flowing from the nostrils

Prevention and Treatment Methods and Key Technical Points for Winter Dysentery in Cattle
1. Prevention. The transmission route of this disease is infection through the digestive tract; therefore, cattle kept indoors in winter should have their feeding management and environmental disinfection strengthened, diseased animals should be isolated and treated promptly, the equipment and secretions of diseased animals should be thoroughly disinfected, manure must be strictly prevented from contaminating feed and drinking water, and manure management and harmless treatment should be strengthened. 2. Treatment. This disease is mainly treated with symptomatic therapy. An equal-amount mixture of turpentine oil and creolin can be administered orally, 25-50 milliliters each time, 2 times per day. For severe cases, fluid replacement should be given promptly, such as glucose saline

Introduction to Prevention and Control Methods and Technical Key Points for Chicken Mites
Chicken mites are a common external parasite of chickens. Prevention and control: (1) Thoroughly disinfect the chicken coop. (2) Soak the affected chicken's feet in warm soapy water to soften the scabs, then remove the scabs, apply 20% sulfur ointment or 10% dimecron ointment or 2% carbolic acid ointment, and apply again after an interval of several days. Using 0.1% trichlorfon solution, first soak the affected chicken's feet in the solution for 4-5 minutes, scrape off the scabs, then scrub the affected area with a small brush.

Detailed Explanation of Key Technical Points for Applying Soybean Rhizobia
The use of rhizobia in soybean production is a mature and widely used technology that can substantially enhance the soybean plant's own nitrogen-fixing capacity during the growing period, supplying sufficient nitrogen for soybean production needs. Soybean rhizobia come in two formulations: liquid and solid. Solid rhizobia are applied by seed dressing or soil application. Liquid rhizobia are used by seed soaking. Soybean rhizobia inoculant can also be added during seed coating, but care must be taken that the coating agent and the rhizobia inoculant are compatible with each other, and that the activity of the rhizobia is not inhibited by the efficacy of the seed coating agent. One

Technical points for cultivating Gastrodia elata with rice husk culture medium
Rice husk is a good "soil" ingredient for culturing Armillaria mellea and cultivating Gastrodia elata in plain areas. The "soil" it forms, namely the filler, is loose, well aerated, has good water permeability and is rich in nutrients, which is beneficial to the growth of Armillaria mellea. The rhizomorphs on the fungus branches and fungus wood cultured with it are thick and vigorous, and the Gastrodia elata cultivated with them grows well. The method is: (1) Rice husk fungus substrate culture: use 1 part rice husk and 1 part yellow sand (volume ratio 1:1) or 3 parts rice husk and 2 parts yellow sand, add water and mix thoroughly, humidity 40%

Cultivation Methods and Technical Key Points for Gastrodia elata in Wide-Mouth Bottles
Requirements for the bed frame: The bed frame is basically the same in form as the bed frames used for indoor cultivation of Gastrodia elata, except that each tier of the bed frame is spaced 30 cm apart, with 10-12 tiers, and no surrounding boards are needed. The bottom layer can be made of wooden boards or sorghum stalk mats. The wide-mouth bottle is 18 cm tall, 8 cm in diameter, with an inner mouth diameter of 4 cm. Cultivation method: Fill the culture material for cultivating secondary solid spawn into the wide-mouth bottle, filling it to a little more than 1/3 of the bottle's volume, sterilize under high pressure, and after cooling, inoculate with secondary Armillaria mellea spawn, place in a 19-22°C greenhouse and culture for 30 days, and it becomes the Armillaria mellea

Key Technical Points for Pre-Planting Preparation of Sexual Propagation of Gastrodia elata in Chongqing
Sexual propagation of Gastrodia elata uses hybrid seedling seeds of Gastrodia elata, propagated under the combined action of germination fungi and Armillaria mellea. The growth period of sexually propagated Gastrodia elata is one and a half years, that is, planted in June to July of the current year and harvested at the end of the second year. Its characteristics are small investment, high success rate, and stable yield. It is currently a relatively advanced high-yield cultivation technique for Gastrodia elata in China. 1. Selection of planting site. The growth of Gastrodia elata hardly requires sunlight, so it can be planted in basements, air-raid shelters, mountain streams and other places with certain ventilation conditions, as well as along courtyard edges, field edges, roadside edges, slope edges, forest edges

Key Technical Points for Protected Cultivation of Leafy Goji (Vegetable Goji)
Every 100 grams of tender stems and leaves of goji contains 5.8 grams of protein, 1.0 grams of fat, 6.0 grams of sugar, 3.96 milligrams of carotene, 0.23 grams of thiamine, 1.1 milligrams of nicotinic acid, and 3.0 milligrams of vitamin C. Regular consumption has health benefits such as improving eyesight, nourishing yin and moistening the lungs, enhancing immune function, and anti-aging. Consumers in southern China are accustomed to using goji tender stems and leaves in soups or stir-fries, and there is considerable demand in some cities; Guangzhou alone has an annual output of about 70,000 tons. Introducing vegetable goji for protected cultivation in the north can both enrich the variety of vegetables
