How to prevent and treat winter diarrhea in pigs? Pig farmers need to master these methods
Winter diarrhea is epidemic diarrhea of pigs in winter. The peak incidence period is from mid-December to mid-January of the following year; the onset is acute, the spread is rapid, and the epidemic range is wide; the incidence rate is high and the mortality rate is low, seriously affecting the growth and development of pigs. Symptoms The incubation period of this disease is generally 12 hours to 18 hours. After adult pigs are infected, watery diarrhea appears. The feces are initially grayish white, gradually becoming yellowish green, with a foul odor. Abdominal distension, vomiting, and body temperature initially rises to 40°C to 41°C. Once diarrhea occurs, the body temperature drops, and the pig is thirsty and drinks eagerly. Piglets within 10 days of age suddenly vomit, followed by watery diarrhea, with curds in the stool, and if not treated in time, they become emaciated and die. The author used integrated traditional Chinese and Western medicine to treat more than 100 cases, with an effective rate of over 96%.

Key technical points for winter management of tea plants to help tea gardens overwinter safely
1. Carry out the garden-closing work by spraying the whole tea plant with 0.4-0.5 degrees Baumé lime-sulfur mixture. 2. Apply 150 kg of decomposed cake fertilizer in holes or furrows, or 100 kg of special compound fertilizer for tea, and finish applying the base fertilizer by November. 3. In conjunction with fertilization, clear weeds inside and around the garden to reduce overwintering habitats for pests. 4. For expanding tea gardens, select good varieties, deeply plow furrows in the tea garden, apply base fertilizer deeply, adopt double-row single-plant planting, low-hole cultivation, and low-position pruning, and strive to complete planting in this winter and next spring.

Field management of wheat-intercropped cotton must be followed up in time
1. Growth and development characteristics of wheat-intercropped cotton. For wheat-intercropped cotton, the cotton seedlings are weak after wheat harvest, grow and develop slowly, bud and flower late, are prone to excessive vegetative growth in the mid-season, and tend to mature late in the late season; moreover, this year the cotton seedling stage was affected by rainfall and low temperatures, and seedling diseases were relatively severe. Field management after wheat harvest must be based on the word "early" and vigorously grasp the word "quick" to promote rapid growth and development of the cotton seedlings so as to make up for insufficient growth during the seedling stage. 2. Quickly destroy the wheat stubble and loosen the soil

High-yield Wild-simulated Cultivation Technique for Oyster Mushrooms in Winter and Spring
Oyster mushrooms produced using wild-simulated cultivation techniques not only taste as delicious as wild ones, but also truly achieve ecological, high-quality, high yields. Even in the cold winter and low-temperature early spring seasons, they can be grown in a relatively enclosed shade shed, making full use of ground heat to produce thick, tender, high-quality oyster mushrooms. This method increases yield by more than 60% compared with conventional cultivation methods, and by more than 40% compared with cultivation methods such as mushroom walls, with a biological conversion rate reaching more than 220%. The specific techniques for high-yield, high-quality wild-simulated cultivation of oyster mushrooms in winter and spring are as follows: 1. Mycelium culture: Use high-pressure or atmospheric-pressure sterilization

How to prevent deformity in winter oyster mushrooms? These measures must be mastered
1. Blue mushroom: During the growth of the fruiting body, a blue halo forms at the edge of the cap, and even the entire fruiting body turns blue-black, without fading until harvest. Preventive measures: For warming measures, methods such as sunlight, heating, and electric heating are preferable. If burning wood or coal is used for warming, closed heat-transfer and smoke-exhaust pipes should be installed, and it is not advisable to build a stove directly in the mushroom house. 2. Big-foot mushroom: After the primordium forms, the differentiation and development speed of the cap is inconsistent, showing only the stipe growing, thick at the bottom and thin at the top, with no mushroom umbrella growing, and the cap

Detailed Guide to Intercropping Oyster Mushrooms in Rice Fields
During the growth and development of rice, intercropping oyster mushrooms using the spaces between rice rows and the special conditions under the shade of rice clumps can provide suitable temperature and humidity conditions for the growth of oyster mushrooms (large temperature difference between day and night, good shading, sufficient scattered light, etc.), enabling high yields of oyster mushrooms, filling the market off-season when few mushrooms are available in summer, enriching summer vegetable varieties, and increasing rice farmers' income. I. Crop rotation arrangement and field plot design: Rice varieties should be selected with strong lodging resistance, tall plants, thick stalks, and resistance to rice planthoppers. Sowing in late May, transplanting in late June, with a density where

How to cope with severe weather in winter and spring greenhouse oyster mushroom production?
In winter and spring, severe weather such as snowfall, cold waves, strong winds, prolonged overcast fog, and sustained low temperatures often arrives uninvited. In mild cases it causes reduced oyster mushroom yields and lower quality; in severe cases it causes total crop failure. Therefore, prevention of and response to severe weather should be strengthened. Main preventive measures: wipe the greenhouse film to improve light transmittance; inspect the greenhouse facilities to ensure the greenhouse's insulation performance; prepare insulating and warming items such as straw mats and old greenhouse film. Response management measures: Cold wave and strong wind cooling weather: Before a cold wave and strong winds arrive, seal the vents tightly, cover the greenhouse film securely, and add a layer of intact old plastic film over the straw mats.

Key Technical Points for Imitation-Wild High-Quality Cultivation of Oyster Mushrooms in Winter and Early Spring
Oyster mushrooms produced using imitation-wild cultivation techniques not only taste as fresh and delicious as wild ones, but also truly achieve ecological, high-quality, and high-yield production. Even in the cold winter and low-temperature early spring seasons, high-quality oyster mushrooms that are thick, fleshy, fresh, and tender can be produced in a relatively enclosed shade shed by making full use of ground temperature. This method increases yield by more than 60% compared with conventional cultivation methods, and by more than 40% compared with cultivation methods such as mushroom walls, with a biological conversion rate of more than 220%. 1. Mycelium culture. Use high-pressure or atmospheric-pressure sterilization, inoculate conventionally, and culture until physiologically mature mycelium is obtained.

Energy-saving and heat-preserving methods for winter cultivation of oyster mushrooms
In winter, when temperatures are low, cultivating oyster mushrooms often results in slow mycelial growth or no growth at all, and even if mushrooms do form, they may be deformed. Heating with coal stoves is costly and can easily cause poisoning symptoms in the mushrooms. The following measures make full use of biological heat to keep the mushroom bags at a relatively high temperature for mycelial growth, which can save cultivation costs. If oyster mushrooms are bagged and inoculated in autumn, by the time the weather turns cold, half the bag will have well-developed mycelium. Keeping such bags warm during cultivation allows the mycelium to quickly fill the entire bag. For those not bagged and cultivated in advance, heating can be applied all at once.

How to prevent deformities in oyster mushroom cultivation in winter?
After the primordia of thick-stemmed mushrooms appear, the differentiation and development speed of the cap is abnormal, manifesting as a small cap, a long stem, and a thick, hard stem, with relatively low commercial value. The main cause is the use of closed insulation and cold protection measures, which leads to insufficient oxygen supply and loss of balance in nutrient transport within the mushroom body. Preventive measures: during continuous low-temperature weather, when the mushroom greenhouse adopts closed insulation and cold protection, attention should be paid to short periods of ventilation at noon, but avoid strong winds blowing directly on the substrate surface, to prevent young mushrooms from dying. Blue mushroom: when the mushroom body grows, a blue halo appears on the edge of the cap,
