Shrimp pond reef-building ginseng has the characteristics of high investment and high returns. It is an effective measure to rationally use shrimp ponds and improve the utilization of shrimp ponds. The following is a brief description of the technology for reef-building and cultivation of shrimp ponds:
I. Clean up the water at the bottom of the pool and remove the sludge and moss from the bottom of the pool. In the case where the bottom of the pool is shallow, excavators can be used to dig the bottom of the pool so that the depth of the shrimp pond can be maintained at 1.5 to 2 meters after filling the pond. Then use the asbestos tiles or woven bags filled with cement and fine sand to lay the edges of the pool without leaving any gaps to prevent the sea cucumbers from entering or escaping.
Second, reef-building can use tiles, stones, fruit baskets or hollow bricks to build reefs. 1. The tiles used for tile reef-building are red rectangular tiles used for building houses. Each group consists of 3 pieces. The three long edges of the tiles are joined together in order to form a triangular prism. The string is tied tightly with a string. A number of reef piles are piled on the bottom of the pool with prisms, and the prisms are placed in the north-south direction. The distance between the reefs is 3m to 5m, and about 2,500 tiles are used per acre. The reef is composed of two upper and lower pyramids, each of which is divided into two rows, north and south. Each lower row contains 5 to 9 prisms, and the upper row contains 4 to 8 prisms (interleaved stacks, with less upper layers than lower layers). One), the upper edge is covered with a tile. 2. Stone Reefs Each reef uses stones of 0.8 cubic meters to 1.0 cubic meters. When stacked, leave as many holes as possible between the stones. Reef stack spacing 4 meters to 5 meters. 3. Fruit Basket Reefs Each reef stack consists of 3 fruit baskets, 2 below and 1 above, tied with string. With the mouth of the basket facing north, the stones are pressed into the basket to prevent the basket from moving. 4. The method of making a hollow brick is similar to that of a tile ridge.
3. After the completion of the water-repelling reef-building, the shrimp ponds will be filled with water and the basic bait will be cultivated for 10 days to 15 days.
4. It is advisable to let the seedlings be released in April and May of each year and in September and October. The number of seedlings per acre is 8,000 to 20,000. Generally, sea cucumber seedlings of different specifications are stocked at the same time or seedlings are added at any time as necessary to maintain the continuity of harvested sea cucumbers.
5. Management should always pay attention to the changes in water quality, and enter and drain water twice a day to keep the water fresh. In the early stage of laying, generally no feeding is required. The sea cucumber mainly feeds benthic diatoms. When the food intake of sea cucumber increases, some algal foods can be fed properly. In order to prevent the sea cucumber from escaping, a net fence may be set within 1.5 meters from the edge of the pool. The bottom of the net is buried about 10 centimeters at the bottom of the pool, and the upper edge of the net is about 30 centimeters above the water surface.
6. Benefit Analysis of Shrimp Pond Reef Raising and Raising 1. Cost: RMB 28,500, including: 700 sea cucumber pool rental fees; 200 sea cucumber pool cleaning fees; 1,000 reef-building fees; 25,600 yuan for seedling fees Head, unit price 3.2 yuan / head, size 40 head / kg); other 1000 yuan (including management, bait cost). 2. The income survival rate of seedlings is generally 80%, the specification of finished products is 10 heads/kg, and the unit price is 70 yuan/kg, then the income per mu is 44800 yuan. 3. Profit 44,800 yuan -28,500 yuan = 1630 yuan. In contrast, the full stocking of large-size seedlings is still relatively low. Under normal circumstances, seedlings of both size and size are stocked at the same time, because the amount of seedlings is large (up to 20,000 heads/mu), and the cost of seedlings is low (the average price is 1 yuan/head to 1.5 yuan/head) and the income will be greater. Generally, the profit per mu can reach more than 30,000 yuan.
