1, to strengthen the breeding work before winter. When the water temperature exceeds 16°C before winter, feed more feeds with high protein and fat content, such as animal liver, fish and snail meat, etc., in order to promote pupa to grow fat, build up body and store certain energy, ensure that During the winter, the consumption of substances in the body goes well for the winter.
2, wintering. The youngsters refer to the young cubs that hatched in the same year. They have small individuals, poor adaptability and cold tolerance. Therefore, it is best to move the baby into the room or build a simple greenhouse for the winter. After draining the pool water, add sediment 30 cm to 40 cm thick, fill the water 10 cm deep, and place 150 -200 grasshoppers per square meter. When the temperature drops to 12°C, the young fishes will enter the sediment. During hibernation, fill the pool again. During anti-freezing during wintering, it is best to keep the room temperature above 0°C to prevent pool water from freezing and freezing. However, the temperature of the water should be avoided too high. If it is not in the warm water for winter, when the water temperature exceeds 12°C, the earthworm will stop hibernating and wake up activities, which will consume physical strength and reduce the survival rate of overwintering.
3, the winter of young cubs. Juveniles are young juveniles that have been kept for one year. Their ability to adapt to the environment has increased, and they are generally allowed to overwinter naturally in the pool. In order to increase the survival rate of overwintering, scientific wintering methods must also be adopted. The wintering pool should choose a place with plenty of sunshine, a quiet environment and sheltered from the wind. There is less silt in the pool and an area of ​​100-300 square meters is appropriate. Before winter, choose sunny days to expose the wintering pond for 3-5 days, then disinfect it with quick lime pond, and pile up appropriate amount of organic fertilizer at the pool. Use 25-40 kg per 100 square meters and fill 50-60 centimeters of water. When the water temperature dropped to 15 °C -18 °C when the pups into the wintering pool, about 100 per square meter. After the larvae enter the pool, they must strengthen management. When the water temperature is above 16°C, feed the palatability feeds with higher protein content to protect the body, while paying attention to adding new water to keep the water fresh.
4. Strengthen wintering management. The management of juveniles and juveniles during wintering is mainly to control water temperature and maintain good water quality to prevent oxygen deprivation. Therefore, change the water or add new water in due course. Generally, the larvae pool changes the water once every 15-20 days, each time changing the water 1/4 to 1/3; the larvae pool changes the water 20-30 days, each time 20-30 cm. During the winter, it is necessary to adhere to the patrol pool and observe the activities and water quality of the juvenile and young cubs, find problems in time, and prevent accidental death.
Solo garlic, also known as single clove garlic, monobulb garlic, single bulb garlic, or pearl garlic,is a variety of Allium ampeloprasum. The size of the single clove differs from approximately 25 to 50 mm in diameter. It has the flavour of the garlic clove but is somewhat milder and slightly perfumed. It originates in Yunnan province in Southern China. The appearance is somewhat akin to that of a pickling onion, with white skin and often purple stripes. Solo garlic offers the advantage, compared to traditional garlic, of being very quick and easy to peel.The harvest time is February to March every year. It has a strong fragrant taste compared with multi(whole) clove regular garlic. It also has a high nutrition content. Its price is higher than regular multi-clove garlic but those people who buy it simply love it.
