The new type of water retaining plate is flexible, It can be used in semi closed tunnels when there is less rainwater on the road surface, allowing special vehicles such as buses to pass first. Once the rainstorm becomes a disaster, the tunnel can be completely closed quickly to avoid greater damage.
Culture technique of semi-slip tongue licking
First, the selection of farms The choice of semi-slip tongue larvae is very important. It is best to choose rich water sources, no pollution, good water quality, suitable water temperature, and better use of underground well waters with suitable hydrological conditions. Indoor sheds and workers have higher insurance coefficient for farming and aquaculture, and they can also use shrimp ponds and ponds for outdoor breeding, allowing the semi-slip tongue larvae to feed on natural bait directly, and their growth rate is relatively fast. Experiments have shown that 5 species of semi-slip tongue larvae are stocked in shrimp ponds. The average monthly time can grow to 450 grams, which shows that its rapid growth, outdoor breeding, water level requirements 1.5-2 meters, if the stocking density can be artificial feeding. Shrimp ponds are designed around the bottom of the tank to dig around 0.5-1m of roundabout gullies to facilitate the wintering and crossing of the tongue. Second, the establishment of pool conditions semi-slip tongue and tongue industrialization of the pool shape of the structure has no special requirements, the general breeding buds, turtles, turtle pools can be fully suitable for the development of semi-slip tongue. Third, the bait-sliding tongues are slow to swim, and they are often distributed in the night. They are evenly distributed in the pool. Most fish stick to the bottom of the pool and gather at the inlet. This puts forward high requirements for the feeding of semi-slip tongues and baits. , It is not only required that the bait is not easily lost in water, but must also be sinking. The food formulation is: >100g (10 per cent of cocoon, 10% of oyster, 20% of sand fish, 10% of cod, 50% of powder, Vc2.5‰, Ve1‰, cod liver oil 5‰, Hetve 3‰, yeast Powder 2.5 ‰), farmers can use this recipe to use small food processing machines to process their own food, low cost, farmers can get more profits, of course, when processing food bait size specifications change smaller than Tai Ling, must be palatable Can be fed. Fourth, water quality management Note the determination of water temperature, by adjusting the amount of water to maintain the quality of feeding water, the amount of water changes per day according to the stocking density of fish, pond water quality conditions, the general high temperature period of 6-8 cycles / day, usually 4 Cycle / day, according to feeding conditions increase the amount of water is conducive to maintaining water quality. Fifth, stocking density pool semi-slip tongue licking stocking density according to water quality conditions, (dissolved oxygen, etc.) generally factory culture 5-20kg/m2, shrimp pond 0.5-1 kg/m2. Sixth, the growth rate of semi-smooth tongue gills grow faster, the annual growth rate of up to 500 grams, and two-day-old fish growth rate of 200-400%, and the gum is very close. VII. Disease Prevention At present, the disease has not been a threat to the development of semi-slip tongue licking. In day-to-day management, close observation of the fish's feeding conditions, swimming, body color, with or without abnormal behavior, timely detection and prevention of disease precursors. Adjust the amount of water in a timely manner, regular thinning seedlings to reduce the stocking density, regular regular medicinal baths and feeding baits, under the conditions, it is recommended to pour the pool once a month, common diseases are: ascites, abdominal disease, rotten Fin tails can be cured with conventional drugs. Eighth, light requirements Semi-smooth tongue like low light conditions, at night can not open the lamp can still smell the food.
The new flood control and water retaining plate is made of composite materials and weighs only 3.8kg. It is easy to use and fast to install. The water baffle uses the "L" shape principle. The erected structure is used to block rainwater, and the ground structure can convert the accumulated water into pressure, so that the water baffle will not fall.
Water absorbing sandbags can be dried and reused. Water active flood sandbags can be stored indoors in a dry place after the flood recedes. Water activiated Flood control bags that have not been soaked can be reused after being naturally dried. 12
When using absorbent sandbags, the bags should be moved to the desired location for flood prevention and interception. After the flood recedes, flood control bags that have not been soaked can be stored indoors in a dry place, while flood control bags that have been soaked can be reused in a dry place after natural drying.
In addition, the water absorbing sandbag is made of environmentally friendly materials and can be treated as general waste without causing pollution to the environment.
