What are the spring control methods for sheep greedy-mouth disease?
In spring, sheep are prone to greedy-mouth disease. The reason is that after the long winter, the sheep lack nutrients in their bodies and are in poor condition; when they suddenly have young, tender, succulent green grass, it tastes especially sweet and delicious. But in early spring, the forage grass has just sprouted and turned green, and the amount of grass is very small, so they cannot fill their stomachs. The sheep would rather go hungry than eat dry grass and yellow grass anymore. Therefore, greedy-mouth disease occurs. This disease can cause sheep to lose weight and become thin and weak due to long-term hunger, affecting growth and health. Prevention methods: First, avoid green grass early in spring, try to avoid grazing on young tender green grassland, and wait until the green grass grows to about 10 cm

Detailed Explanation of Key Technical Points for Increasing Spring Tea Yield and Improving Quality
Delaying light pruning: Conventional light pruning of the tea canopy is carried out from December in winter to February of the following year. Practice has shown that doing so has three drawbacks: first, the branches are prone to frost damage after pruning; second, the overwintering buds are cut off, delaying the sprouting time of spring buds; third, the nutrients already accumulated in the branches on the tea canopy surface are cut away, affecting the sprouting vigor of spring buds and the growth of thick strong branches, ultimately affecting spring tea yield and quality. Therefore, the pruning time should be after the frost period, preferably so that the first spring tea can be picked 30 to 40 days after pruning. Advancing topdressing: Conventional topdressing is mostly carried out in early to mid-March, when spring buds

Be Alert to Porcine Epidemic Diarrhea: Pig Farmers Should Take Precautions Early Around Spring Festival
Epidemic diarrhea occurs mainly around the Spring Festival (from December to March of the following year), and mostly breaks out after cold, damp weather or a sudden cold wave, showing endemic prevalence. Clinical symptoms: piglets first vomit and then develop diarrhea, with thin feces that are yellow or green and mixed with milk curds, arched backs, tucked tails, sensitivity to cold and shivering, and in the later stage sunken eyeballs and severe dehydration, with body temperature normal or slightly elevated; the course of disease is 5-7 days, and the younger the age, the higher the mortality rate, with a mortality rate of 30%-40% in piglets within 7 days of age; adult pigs refuse feed, show projectile diarrhea and pass watery thin feces,

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.

Key Technical Points for Pest Control and Fertilization of Wheat in Winter and Early Spring
When temperatures are relatively low in winter and early spring, pest control and fertilization in wheat fields should pay attention to the following two points: For pest control, to control wheat aphids, red spiders and other pests, spraying omethoate is more effective than dimethoate. This is because the insecticidal efficacy of dimethoate against pests decreases significantly as the temperature drops, while the efficacy of omethoate is less affected by temperature and can exert normal insecticidal action at temperatures below 15°C. Similar to omethoate is fenvalerate; the toxic efficacy of fenvalerate at 15°C is instead stronger than at 25°C. Fertilization: For topdressing, applying ammonium bicarbonate is better than urea. Ammonium bicarbonate

How to raise goslings in early spring? Detailed explanation of key feeding points
Select good goslings. Healthy goslings are lively in behavior, have big and bright eyes, respond quickly, can stand firmly after their down dries, and have strong calls. When held up by the neck with your hand, their feet quickly retract. Weak goslings with large abdomens or crooked heads should be culled. Suitable temperature: 25°C-28°C for 1-5 days of age, 23°C-26°C for 6-10 days of age, 20°C-24°C for 11-20 days of age, and 17°C-20°C after 21 days of age. Careful feeding: feed at fixed times and in fixed amounts, and it is best to feed small amounts frequently, adding more as needed, until they are 80% full. Goslings

Spring management of garlic after overgrowth must start early
For garlic sown in autumn 2006, temperatures from planting through early December remained higher than in previous years, which accelerated the growth of the garlic sprouts. Before winter, the garlic grew to 7-10 leaves (the optimal seedling age for overwintering is 5-7 leaves), showing overgrowth, and had already begun "mother bulb rot," with pest problems occurring. As a result of overly rapid growth, the garlic suffered from poor nutrient accumulation, reduced stress resistance, slow greening after the New Year, severe disease, and reduced high-yield potential. In spring, garlic must complete a series of growth processes including greening, vigorous seedling growth, garlic scape elongation, and bulb enlargement. On the basis of applying sufficient base fertilizer, garlic in spring

Detailed Explanation of Key Garlic Spring Management Techniques
I. Management during the regreening stage: After Awakening of Insects, garlic begins to regreen, so it should be watered and fertilized promptly. Along with watering, apply 20 kg of diammonium phosphate per mu or 25 kg of ternary compound fertilizer. Then carry out shallow hoeing to loosen the soil, raise the temperature, and preserve moisture. Around Qingming Festival, when yellow tips appear on the leaves, carry out the second topdressing promptly and increase the frequency of watering, generally watering once every 10-15 days, to promote plant growth. II. Management during the garlic scape growth stage: In early May, garlic scapes begin to differentiate. After the Beginning of Summer, garlic scapes enter a period of vigorous growth, and during this period fertilizer and water management should be increased.

How to choose sweet potato varieties? Provincial Crop Institute experts recommend varieties for spring, summer and autumn planting
Sweet potatoes can be planted in spring, summer and autumn. Spring planting is generally done in March to April, summer planting is generally done in May, and autumn planting is done within one week after the Start of Autumn. Below are several sweet potato varieties suitable for planting in our province. Jinye: a new stem-tip vegetable sweet potato variety. This variety has tender stem tips, low crude fiber content, and good palatability after cooking, making it suitable for use as a vegetable. With open-field cultivation, the stem tips can be picked about 10 times over the whole growing period, with 250 kg of stem tips picked per 667 sq m each time, and a picking interval of 15 days. Per 667 sq m, it can yield

Key Technical Points for Spring Feeding and Management of Working Cattle
Spring is the busy season for working cattle, yet forage is scarce as the old supply runs out before the new comes in, and the cattle's physique has declined after a long production period. If feeding and management are not strengthened and nutrition not increased, it can easily affect spring plowing and delay farm work. Therefore, doing a good job of spring feeding and management for working cattle is crucial. To do a good job of spring feeding and management for working cattle, the following points must be noted. 1. Effectively carry out feeding and management before work. If a working cow is not well maintained in spring during the production period, it cannot be remedied by supplementary feeding during the working period.
