The management technology of astragalus in cement pond culture
The Dianchi Lake can be made of masonry. The wall of the pool, the bottom of the pool, and the corners of the pool should be cement mortar or three-segment soil. Where there are many limes, the pool is also built with three-soil. At present, there are three kinds of common dip pools.
1 Self-replacement water conservation pond: It is characterized by a 80 cm deep pool at the bottom is higher than the drain, the pool is rectangular, with an area of ​​3X4 or 3X5.
2 Inhabiting and feeding bait pool: It is characterized in that it is separate from feeding bait.
3 Simple Pool: In some areas, the base of the Dianchi Lake is slightly deeper, and the bottom of the pool may not be paved with bricks or stones, which can reduce the cost of pool construction.
No matter what the pond has to open an intake, a drainage culvert and an overflow. It is advisable to connect a water tank to the water inlet so that water can fall from the water tank into the pool. In this way, water can be aerated and aerated on the one hand. On the other hand, it can prevent the eels from escaping along the water outlet. Open a drainage culvert on the other side of the inlet, and open an overflow on the surface of the pool. All the outlets should be installed with fish-blocking facilities. One third of the water in the pond can also be cultured with aquatic plants such as water lilies, water juniper and arborvitae, and pumpkins are planted next to the pool. The pool is covered with shade to create a good ecological condition for the growth of the bonito. Before stocking, Dianchi is sterilized with quicklime clearing pond. Generally, 50-60 kilograms of quick lime are used after draining the water per acre of the pond area. After about half a month of disinfection, the seedlings can be stocked. Home-breeding Astragalus can also use sporadic water surfaces, such as small ponds behind houses, to convert them into a carp pond. The area can be large or small, but there must be a source of water so that artificial water or water can be changed during drought. Pool depth of 0.7-1 m is appropriate. New fish ponds, the best choice for sheltering sunny, near residential, clean water sources, an area of ​​about 2-10 square meters, the best 4-5 square meters. No matter what kind of fish pond, you must not leak water.
2, feeding and management technology 1 good water source water quality: Astragalus growth requirements of water quality fertilizer, clean, deep oxygen foot, Astragalus is hi of shallow water and thermophilic animals, so in early spring, the water level should be controlled at about 6 cm to facilitate the water temperature rise. There are many mucus on the surface of the skullcap. If the stocking density is high and the water is not changed in time, the mucus will accumulate. These mucilages consume a large amount of dissolved oxygen when they are decomposed, and generate heat, which causes the water temperature to rise significantly and cause the death of the jaundice. Therefore, we must do a good job in changing the water to keep the water fresh, increase the appetite of the jaundice, and strengthen the conversion of the bait. Changing water is an effective way to remove dirt from ponds, increase dissolved oxygen, and keep water fresh. Feeding should not be too much, and more will rot and stink, so that the quality of water is degraded. Normally, one or two days after feeding, new water should be replaced. During the growing season, the depth of water is kept between 10 and 15 centimeters, and the water depth is adjusted depending on the weather.
2 Pay attention to the change of water temperature: Before and after Ching Ming, when the water temperature is generally stable above 10°C, you can begin to do preparation work. The first is to clean the environment around the culture ponds and then disinfect the drugs. The method is to make a 50 g/L saturated lime solution with quicklime, filter out the clear liquid, and add 10 g/L caustic soda to stir to make a strong alkaline disinfectant, and then use the liquid to spray disinfection around the culture pond. Finally, the overwintering cover on the surface of the Dianchi Lake was removed and the disinfectant was immediately sprayed on the mud surface and the inner wall of the pool. After completing the above work, check the wintering conditions of Huangpi and whether the facilities in Dianchi Lake are in good condition. At the same time, the mud inside the pond must also be trimmed and planted with aquatic plants such as mushrooms, oysters, and taro. The temperature in spring is low, and sometimes the phenomenon of “cold winter†appears. Therefore, we must do a good job of insulation work. Initially, we can temporarily cover the overwintering plastic film, cover the sun for a few hours at noon and noon, cover the film in the afternoon, and conditionally use electric lights or other heating facilities. In addition to planting aquatic plants in the summer, you can also plant some melon beans in the pool and shady shade. In winter, it must be cold and drained, covered with a layer of straw, and keep the pool temperature and soil moist. Prevent the carp from freezing to death, but do not walk or stack heavy objects in the pool so as not to compact the underground tunnel and cause the ventilation holes to block, resulting in the death of suffocation.
3 strengthen patrol observation: often pay attention to observe the changes in water quality, water temperature, depth of the pool, all the heavy rain to prevent heavy rain, to prevent flooding washed pool or squid turn the pool.
4 Anti-virus and anti-hazard: To prevent toxic substances from entering the rearing pond, no geese or ducks should be allowed in the pond so as to avoid swallowing the baby and reduce income.
5 properly maintain the depth of the water layer: generally 10-15 cm depth is appropriate, deepen the water level in the hot season, but not more than 20 cm. Because Astragalus is more sensitive to the temperature difference, once the temperature difference of the water exchange exceeds 3°C, the Astragalus may suffer from flu and gradually die. Therefore, when changing water, it should be replaced with warm water as much as possible. The general measure is to build a new reservoir, and then change the water after exposure. The number of water changes should be based on the stocking density of Astragalus, feeding conditions, temperature and other flexible control, the time is generally sunny at noon as well. Do not change the water when the temperature is low. When the temperature rises to 15°C, the water can be changed once a week. Each change of water accounts for 1/4 of the total water volume. When the temperature rises to around 20°C, the water can be changed every 5 days, and the water can be changed every time. / 30 Always infuse new water, change the water interval, and change it once in seven days in spring and autumn, and in three days in summer. The number of water changes must also be determined by the source of water, the amount of jaundice, and the quality of the water. After entering the winter, the water should be drained and the pool soil should be kept moist. And cover a layer of 6-8 inches of straw or other weeds on the pool soil so as to avoid freezing of the pool water, because the pool is not water, especially to prevent cats, dogs, and rats from entering the pool and eating squid.
6 Feeding of bait: Aunt Huang has a devastating phenomenon. Therefore, it is advisable to feed by size and size. The hatchlings that have just hatched for 4-5 days are mainly fed with leeches, rotifers, fresh fish paste and algae, with the best leeches. Afterwards, we can feed stew, snail, cocoon and so on step by step. Feeding baits, the amount of food depending on the situation to eat and control flexibility, to ensure that eating well without leaving residual baits to poison the water quality. When the body length reaches 6-8 centimeters, it will be bred. Chengyu mainly feeds quail, cockroach, small frog, fly maggot, shrimp, cocoon, snail meat, etc. It can also feed some mixed fish paste or other animal viscera. Especially in the best, every 5-6 grams of fresh oysters can grow 1 gram of oyster meat. It is also possible to feed part of plant foods such as wheat bran, rice, fruits, and vegetable cuttings. In the future, it is necessary to explore the “mixed bait†feed. Feeding baits should be timed, positioned, quantified, and quantified so as not to inflict diseases on the cubs due to overeating. The eel was out of bed at night and started feeding at 4-5 o'clock in the afternoon or in the evening. Afterwards, it was fed in advance on a daily basis. About 10 days of skillful bait could be fed at 9 am or 2 o'clock every day. The bait can be fed every other day to increase its food intake. The daily feed amount is 6-7% of the total amount of carp, fine material should be less, and coarse material should be more. Two feedings are made in the morning and evening, and feeding is concentrated on bait stations. The bait station can be made of wooden frames, bamboo poles, aluminum meshes, or nylon mesh fabrics, etc., and fixed in the pool. Water temperature has a great influence on the food intake and feeding activity of Astragalus membranaceus. 15-28°C is the optimal growth temperature and the feeding activity is enhanced. At this time, it is necessary to feed and feed well; below 15°C, feeding is slow, affecting the feeding; below 10°C, Stop eating and go into the cave to hibernate as the water temperature drops.
