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

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.

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%.

There's an art to winter pond fish harvesting, and mastering the method is key
Winter is a favorable time for harvesting and marketing pond fish, but winter harvesting is also a potential trigger for fish diseases the following year. Therefore, extra care must be taken during winter harvesting to avoid injuring the fish as much as possible, so as to reduce the occurrence of fish diseases and improve the economic returns of the pond. 1. Clear debris from the pond before harvesting. Wooden stakes set up in the pond for theft prevention, uncleared large rocks, and aquatic plants on the water surface such as water hyacinth and alligator weed can all interfere with normal seining. To carry out winter harvesting smoothly and safely, these must be cleared before harvesting

Comprehensive Utilization Methods of Fish Fingerling Ponds During the Winter Fallow Period
Raising market-size fish: Using winter-fallow fingerling ponds to raise one season of market-size fish can both increase production and help ease the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are combined into ponds, so as to make full use of the growing period. Stocking rate is calculated at a maximum water depth of 2 m, generally 125-150 kg per mu. The stocking ratio is generally about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp.

Detailed Explanation of Key Techniques for Lily Intercropping and Relay Cropping
In the Taihu Lake region of southern China, lily production often uses intercropping and relay cropping to increase income per unit area. Practicing intercropping and relay cropping has some effects on lily growth, and bulb yield decreases somewhat, but the total income per unit area is higher than the returns from monocropped lilies. If the timing and management of intercropping and relay cropping are arranged properly, it is beneficial to lily growth and can also achieve high yields at the same time. Yixing lilies are propagated from daughter bulbs, require a large amount of seed, multiply only 2.5-3.5 times in one year, and the ground space is idle for a considerable period. Local experience in arranging intercropping and relay cropping

Key Technical Points and Methods for Gastrodia elata Management in Winter and Spring
After November, as temperatures gradually drop, the new Gastrodia elata tubers stop growing, their size becomes fixed, and they enter dormancy directly, so low-temperature freezing damage should be prevented. In particular, the arrow tubers (Jianma) are easily damaged by freezing during overwintering. It is best to use arrow tubers for medicinal purposes when harvesting Gastrodia elata in winter, and to sow or store the small tubers (Mima) and white tubers (Baima) in time for spring planting. If they are not harvested in winter, cold-protection measures must be taken before freezing, such as covering with tree leaves to keep warm and prevent freezing, and removing them the following spring to facilitate growth. The temperature should be maintained at 1-5°C, and the humidity should be maintained at 30%.

How to prevent common pig diseases in winter? These methods you need to know
Before winter arrives, do a good job of immunizing the breeding herd: such as foot-and-mouth disease, epidemic diarrhea, transmissible gastroenteritis, swine fever, pseudorabies, blue ear disease and other preventive vaccinations, and do a good job of deworming. Sow immunization: before farrowing, the injections of transmissible gastroenteritis and epidemic diarrhea bivalent vaccine, pseudorabies and other vaccines should be done according to plan, so that sows are at a relatively high immune level. Piglet immunization: there is considerable controversy over blue ear disease immunization; it is recommended to use blue ear disease attenuated vaccine at 15 days of age. Drug prevention

Discussion on the Application of Interferon in the Treatment of Canine Infectious Hepatitis
Canine infectious hepatitis is an acute septicemic infectious disease caused by adenovirus. It is characterized by central necrosis of hepatic lobules, intranuclear inclusion bodies in hepatic parenchymal cells and cortical cells, and prolonged bleeding time. Canine infectious hepatitis is seriously harmful to dogs and causes significant economic losses to the dog breeding industry. The virus has considerable resistance; under low-temperature conditions, it can survive in soil for a long time, remaining pathogenic after 10-14 d, and can also survive for a relatively long time in kennels. Sick dogs and recovered virus-carrying dogs are the source of infection for this disease, and their blood, secretions and excreta

Detailed Explanation of Four Key Points for Winter Cultivation and Management of Oyster Mushrooms
1) Light should be strong rather than weak. Light is not only an important way to raise the shed temperature in winter, but also an important means to increase yield and improve mushroom quality. Light intensity and duration should be determined according to the insulation performance of the mushroom shed and weather conditions. If the insulation performance of the mushroom shed is good and the nighttime temperature can be maintained above 5°C, then the straw mats on the shed roof can be uncovered early and covered late, extending the daytime light duration as much as possible; otherwise, the daytime light duration in the mushroom shed should be correspondingly shortened. As for weather conditions, when the temperature is below 5°C, on sunny and cloudy days, under the condition of ensuring a shed temperature of 5°C
