The market price of Huangqi before and after the Spring Festival every year is more than twice as high as from April to September, and the goods are sold well. Therefore, a large-scale collection of wild jaundice in the cage for a short period of time in the autumn, and sales before and after the Spring Festival, can obtain substantial profits.
The project has a small investment in fixed assets, simple operation, quick cash flow, and it is a good way for farmers to quickly increase income and get rich.
This practice is described as follows:
1, choose a good water setting cage
The best choice is to set the water tanks for the cages to be the ponds, followed by the lakes, ditches and reservoirs with relatively stable water levels. However, no matter what kind of water bodies, the water sources should be sufficient, the water quality should be good without pollution, and the light should be good. The cages are sewn with polyethylene mesh sheets, each having an area of ​​10 to 20 square meters and a depth of 1 to 1.2 meters. Net cages in the water are fixed with wooden stakes or float with oil drums. Before stocking up, the yellow locust breeds a large amount of water peanuts or oil grass in cages, and fills it with cages for habitats.
2, fully grasp the quality of the box into the box
Restocking time is generally completed before September of each year when there are a large number of yellow tadpoles and the purchase price is low. The purpose of holdings is to maintain weight, obtain seasonal differences, and not consider growth gains. Therefore, adopting varieties do not need to be deliberately pursued. However, as with the conventional breeding of seedlings, they must strictly control the quality and require the purchase of cages to catch disease-free individuals in order to ensure the survival rate. It should be noted that the high temperature in the fall may easily lead to feverish fever of the jaundice and cause a large number of deaths. At the time of catching up, the yellow locust in the households of the resettlers should change their water more than 2 times a day and place them in a cool place. Winter holdings should be purchased in the catcher's home temporarily holding no more than 2 days of the Astragalus, the harvest time should be relatively low temperatures in the morning, the transport time should be as short as possible, transport barrels of water and astragalus weight half. The recovered oysters were restocked in a timely manner.
3, correct stocking
For the "collective goods" received by the Astragalus, they should be placed in different cages according to the size of at least three grades. Disinfect with 5 to 10 minutes with 3%~5% saline before entering the box. Stocking density is generally 2.5 to 5 kg per square meter cage, and the specifications of large stocking weight, small size stocking weight.
4, holding management
1 Feeding: After 3 days into the box, the yellow eel began to feed fresh meat minced by a meat grinder. It was fed once a day in the evening and the bait was put on the plants. Each box had 3 to 4 feeding sites, and the quantity was eaten every time. Light is degree. In the middle and lower reaches of the Yangtze River, basically no food is available after the end of October (water temperature below 15°C).
2 Antifreeze: As the temperature gradually decreases, it is necessary to deepen the depth of the pool water and maintain the lush grass nets.
3 Anti-interference: When the temperature is low in winter, the activity of jaundice is very poor. It is necessary to resolutely put an end to turning the plants and agitating the pool water. Otherwise, the jaundice will fall into the bottom of the tank and unable to swim back to the aquatic grass to inhabit.
5, grasp the timing of timely sales
In the winter, we should keep abreast of the prices of major markets in the country and stocks in the main support areas in order to predict changes in the market price changes and seize the opportunity to sell at the right time to obtain the best possible return.
