The silver needle, also known as the white needle, one of the treasures of White Tea. because of its white, such as silver, the shape of the needle and so named. Silver Needle Tea's aroma is fresh, soup color light yellow, taste fresh and cool, is the best in white tea, known as " beauty " , " king of tea " in tea. Its fresh leaf raw material is all tea bud, pick standard is one bud one leaf, grow about 3 centimeters. The silver needle is suitable for the general population to drink, the taste is warm and cold, has the effect of antipyretic heat treatment and detoxification, and is often used as medicine.

1. Can eliminate a variety of pathogens and pests. After the lime is dissolved in water, it turns into a strong alkaline solution, which can kill the trash fish, insects, grasshoppers, clear mud moss, water net algae and some soft aquatic plants that remain in the pond, as well as kill parasites and pathogens. Etc., so the sterilization effect is particularly good.
2. Improve the water environment. Quicklime can neutralize the organic ions decomposed by the organic matter and reduce the carbon dioxide content, so that the water body presents a more suitable slightly alkaline environment for fish. In most cases, when the fish is sick, the body of water is often acidic. Therefore, the regular application of quicklime in the breeding process regulates the water quality to maintain the alkaline environment of the water, and it can also reduce the occurrence of fish diseases.
3. It is good for fish growth. The calcium ions in the quick lime are beneficial to the growth of fish bones, and can also replace the nitrogen, phosphorus and potassium elements in the sludge. It is an indispensable nutrient for growth and reproduction of plankton. A specific method of disinfecting the quicklime: After finishing the pond, disinfect it on sunny days before and after the fish is released for two weeks. In the pool, 5 to 10 cm deep water is retained, and several small pits are dug around the bottom of the pool. Lime is used for 60 to 75 kg per mu, and the whole pool is scattered all over. The amount can be increased or decreased according to the amount of sediment in the pond. After application, agitating the water body is more effective, and no peripheral dead corner is left during disinfection.
The individual size, density, and collocation of individual fish stocks for rational stocking programs have a direct relationship with their own management levels, feeding methods, time of exit, and the required fishery specifications. The main points to be grasped are: the same batch of fish is required to be as tidy as possible (except for the round of catching), but also has a suitable density, and the variety should be reasonable. There is a difference in feeding habits between the main fish and the matched fish, so as to make full use of water space and feed resources. In particular, to raise eating fish, the pond must be matched with flowers and white catfish to regulate water quality. You can also consider putting a small amount of fierce fish to eat the wild fish in the pond, but you need to record the number and finally catch it out of the pond.
Strict quality of the varieties has two meanings: First, the requirements are thoroughbred. The national thoroughbred evaluation committee recommends breeding of fish. Its economic traits are good, the growth is fast, and the quality is good. Second, the fish fry is required to be robust, disease-free, and non-destructive. Strong swimming ability.
Precautions for stocking fish species
1. Seedling transportation in spring is also the season in which fry is released, and off-site transportation of fry is an important part of freshwater aquaculture production. Transportation should be safe and efficient, and the survival rate of transportation should be guaranteed and improved. When transporting seedlings, care should be taken to develop a thorough transport plan before transportation and prepare for loading, unloading, disinfecting tools and drugs. The transportation density shall be determined according to the type, specification, water temperature, water quality, transportation time, transportation method and oxygen supply equipment of the fish. Should choose the lower temperature of the sunny transport of fish species, should be stopped before the start of the fish feed.
2. Before stocking, prepare the fish before the pond should be checked before the clear pond after the efficacy has passed, the early spring water temperature is low, the toxicity disappears slowly, should be taken in advance to put experimental fish test.
3. Pay attention to the difference in temperature when ponds are under consideration. The temperature difference between the water in the fry container and the pond water should not be too large, so as to avoid stress reactions, especially small-scale fry, it is easy to cause death.
4. Disinfection practice has proved that the timely disinfection of purchased fish fry can effectively prevent the occurrence of fish disease. In early spring, the temperature is low, and fry is inevitably traumatized during its operation and loading and unloading. Disinfection must pay attention to 3 points: 1 drug should be used with the current use; 2 drug dose should be accurate, to avoid insufficient dose or overdose; 3 dipping time should be appropriate, found that fish species have patience, should immediately add water or Put it in the pond.
Strengthen management
1. feed. After the spring season, the weather is erratic, and the temperature is high and low. Pay attention to timely adjustment of the feed amount.
2. Water transfer. As the weather gets warmer and the temperature rises, it is necessary to add more water and raise the water level.
3. Increase oxygen. People tend to think that the pond will be deprived of oxygen in July and August and the pond aerator will be later. In most cases, the fishermen and fishermen will only be erected when there is obvious signs of lack of oxygen in the pond in May and June. This poses risks, especially high-yield ponds. (Zhang Xirui)
Spring stocking precautions
Spring blossoms, everything recovers. Under the current circumstances, doing a good job in aquaculture and making a good start in fishery production are the first major considerations for aquaculture each year. In terms of general breeding techniques, the following key points should be carefully grasped: The thorough disinfection of ponds after the disinfection of ponds is well-opened is an indispensable part of the breeding process and should be given high priority. Liquor disinfection is often used in production. The main advantages are:
