1 Putian fielding and lotus planting should be conducted in Putian where adequate water supply, irrigation and irrigation facilities, good water quality, and strong water retention are required. When Putian is selected, a fish pit with a depth of 1 to 1.2 m and an area of ​​50 to 70 m2 should be dug at one end of the field, and a fish with a width of 1 to 1.5 m and a depth of 80 cm should be excavated at the end of the fish pit leading to Sakata. Gully; field ridges should be raised to a height of 1 to 1.2 m after the ramming; the import and export of water is set to prevent fish escape. Before 10 to 15 days before planting, 1500-2000kg of composting and 30-50kg of compound fertilizer shall be applied per acre (250-300kg of which will be spread into fishing pits and fishing ditch to cultivate food organisms), and plowing, After mashing 1 or 2 times, it is ready to discharge water. The medium- and late-maturing varieties should be used for raising leathery beard. When the temperature rises to 15°C in the spring, they can be planted. Seedlings require fresh, disease-free, non-invasive, with more than 2 nodes, and 0.5kg or more of single branch weight. The planting density of earthworms is 20.5m. Planting holes should be arranged in a staggered manner. The top buds are opposite each other. The buds on the edges of the domes are all inwards. The buds of the domes are inserted obliquely downwards (8 to 12cm deep), and the rear section is slightly upwards warped.
2 Scientific stocking and feeding of fish species 10 days before phytoseiculture and before fish stocking, 60 to 70 kg of lime slurry per acre is used to disinfect and disinfect. Overwintering fish stocking should be carried out when the water temperature is stable at 18 to 20°C, and the fish species with 8-10cm length per acre is between 800-1000 fish species; when stocking fish species with a small size of 3-5cm or more in the year of stocking, stocking is done per acre. 1500 to 2000 tails. The stocking specifications of the same species should be consistent so as not to kill each other. Before stocking, the fish should be sterilized in a 2.5% saline solution and a 1mg/L bleaching powder mixture for 5 to 10 minutes. After being stocked for 1 month, the leather beard can be stocked with large-sized oysters and breams in small quantities. In addition to using plankton, benthic organisms, lotus root pests, and other bait organisms in paddy fields, Saitama cultivated leather beards also require artificial feeding. In the earlier period, animal feeds were mainly used to feed animals, such as fish and shrimp meat, snail meat, and chopped animals and viscera. At the same time, they were fed with bean cake, bran, rice bran, and duckweed in appropriate amounts; when animal feeds were insufficient in the middle and later stages, The ratio of feeding plant foods may be increased, or animal feeds such as fish meal, blood meal, cocoon and other animal feeds may be mixed with plant feeds and fed into a batch. Feeding of bait should be timed, positioned, qualitative, quantitative, and fed 2 to 3 times a day by "slow-fast-slow" and "less-more-less" methods. From June to September, it is a period of rapid growth of leather beard. It is necessary to intensify feeding according to the growth condition. The amount of daily feeding is 6% to 1.0% of the fish body weight. In addition, it is also possible to use the fluorescent lamp to attract bait at night.
3 Field water management and leather beard carp disease prevention and fish growth, flourishing stage, the surface water level should be deepened to more than 30cm, usually every 5 to 7 days to add new water once, control the transparency of field water about 30cm, when the beginning of scarring The water level can be lowered appropriately. When feeding animal foods such as chicken intestines, change the water frequently. In order to prevent diseases of lotus root and leather beard, 20 mg/L of quicklime is splashed every 10 to 15 days during feeding, and 1 mg/L of bleach is spilled once a month. The drug can also be mixed in the bait to make the bait, the first day of each kilogram of fish with sulfadiazine 0.1 ~ 0.2g, halved in the first 2 to 6 days; per kilogram of fish with antibiotics 5 ~ 10mL, Feed for 5 days.
(4) Fishing, breeding and harvesting of leather beard Anchovies is a tropical fish. If the water temperature is lower than 7-8°C, it will be frozen or frozen. Therefore, it must be harvested and sold in time. When fishing, you can catch large and stay small. At the time of final arrest, the dewatering field can slowly dry out, allowing the fish to swim into the fish pit and then ditch the water and concentrate fishing. After harvesting, the leather beard carp is first raised in a clear water pond for 3 to 4 days and sold again to facilitate the removal of mud and smell. When many stop leaves appear in the field, lotus roots can be harvested.
Lotus roots, leather and beardhead (Clalqsa Leather), per acre (667 square meters below the same) lotus root production 2000 ~ 2500kg, leather beard carcass 500 ~ 600kg (a body weight 0.5 ~ 1kg); such as feeding and management, leather beard production can be Up to 800kg. The total output value per acre of lotus roots and beard owls is 9,000 to 12,000 yuan, and the net profit is 5000 to 6,000 yuan.
