There is a large seasonal difference in the sales of Huanghua in the whole year. Many farmers like to feed the yellow peony for sale before and after the Spring Festival. However, as the weather gradually turns cold, jaundice generally stops feeding at temperatures below 10°C, and is unresponsive. As the temperature decreases, it enters hibernation. Therefore, in order to allow the yellow peony to survive safely and smoothly, it is necessary to master the cultivating techniques of jaundice, otherwise there will be a large number of jaundice deaths.
1. Feeding and management of yellow oysters before raising
(1) Intensified domestication is an intensive management of the jaundice before it is stopped. At this time, it is necessary to invest more in animal feeds that are best eaten by the locusts, have good palatability, and have high protein content, such as fly maggots and cockroaches.
(2) Prevention and treatment of diseases such as enteritis, parasites, and hydromycosis should be conducted before the yellow pheasant raises winter.
1 Saprolegniasis: It is a fungal disease that easily occurs when the water temperature is below 20°C. The prevention and control of watery mildew use "Yubao Shuiyuling" 5mg/L water Quanchiposa, continuous use 2 to 3 days, and then once again use "Scorpion Silver Iodine" 2ml/m3 water Quanchiposa.
2 Prevention of enteritis with "Saobao virus clearing" 3 g / kg material, "Yibao rotten skin bleeding" 5 g / kg of material, "King-dimensional" 10 g / kg of material, and add the appropriate amount of adhesive and lure After the food agent was mixed, it was fed with astragalus and fed continuously for 3 to 5 days.
3 Parasites of Astragalus are classified into endoparasites and ectoparasites. The prevention and treatment of ectoparasites (grasshoppers) was carried out in a water bath of 1.2 to 1.5 ml/m3 in the “Saibao Water Insect Clearanceâ€. Attention was paid to killing and killing. For the extermination of internal parasites, 2 to 3 g/kg of material is added to the internal parasite. Add appropriate amount of binder and attractant to mix and feed. Use 3 to 5 consecutive days.
In the process of disease prevention, the medicine should be evenly and more frequently fed, so that all the jaundice can be prevented and treated to ensure the safe wintering of the jaundice.
2, support conditions
Winter maintenance is generally performed in concrete pools and earthen ponds. The raising ponds should be constructed in places with high ground, convenient drainage and irrigation, adequate water sources, good water quality and no pollution, and can be carried out indoors or outdoors. Family small-scale maintenance, should be selected near the house for easy management. The shape of the pool is generally square or rectangular. The area of ​​the pond is 10 to 15 square meters, and the depth of the pool is 1 to 1.2 meters.
(1) Land: Dig 40 to 50 centimeters from the ground, dig out the earth and build an embankment around it. The rafts should be 50 to 70 centimeters in height, 60 to 80 centimeters wide, and should be built into the drains to prevent escape.
(2) Cement pond: Dig 30 to 40 cm from the ground and build a soil pool. Then, the walls of the pool and the bottom of the pool are lined with bricks and cement. The inner wall should be smooth. The wall of the pool must be more than 20 cm above the ground. The top of the wall should be made of bricks. The inlet and outlet must be covered with a fine mesh cloth. The drain is usually plugged with a wooden stopper and pulled out when the water is drained. The bottom of the pool is covered with a layer of organic soil, which can be excavated from more fertile paddy fields. Generally, it is better to use taupe soil. It should be moderately soft and hard, and slightly sticky. It can be used to poke hole test in the mud with a wooden stick. Holes do not collapse, then put some stones, tiles, tree roots, etc. in the pool to create artificial caves for burrowing in the yellow crickets, and also easy to capture.
3, support methods
To support the yellow cockroach, whether it is purchased in the city, captured in the wild, or cultivated on its own, it must be selected without injury, disease, and strong in health. The general specifications are individuals with more than 8 to 10 tails per kilogram. Those trapped with hooks should not be raised. The fish body was disinfected prior to entering the pond, and the average breeding density was 10-25 kg per square meter. If it is the first time raising or lack of experience, the density of larvae should be appropriately reduced. On the contrary, it can be increased appropriately. When there is a large number of feedings, “multiple placement methods can be applied every other dayâ€, that is, the larger individuals are placed first, and the large individuals are all put into the soil, and then put into general individuals, and put smaller individuals afterwards. When releasing, try to make the whole pool of Astragalus evenly distributed.
4, maintenance management
In the early stage of feeding, the astragalus still feed, and at this time, it is necessary to manage feeding, water quality, and disease prevention. When the temperature of the water drops below 10°C, the eel will enter hibernation.
Huang Hao eat fresh animal feed. The most popular food oysters, fly maggots, and river fleas are best fed with these fresh foods. Feeding is usually done after 2 to 3 days of feeding. The first feeding amount is 1% to 2% of the total weight of quail. On the next day, if the feed is basically consumed, the feeding amount can increase to 2% to 4% of the total weight. If there is more surplus, then Appropriately reduce the amount of feeding. Feeding amount is often adjusted according to changes in water temperature. The water temperature can be high, and the water temperature should be low or low. In the long-term hunger, Huang Huan has habits of self-neutral eating, so feeding must be sufficient. In the rearing stage, fresh feed must be provided to feed the feed, and residual baits should be removed in a timely manner to add fresh water to prevent infectious diseases and prevent water damage. The feeding principle is to feed more on sunny days, less on cloudy days, and less on rainy days. Feeding should be adhered to until the astragalus completely refuses to eat so that it can effectively prevent the jaundice from falling out during feeding.
After the water temperature dropped below 10°C, the yellow locust stopped feeding and began to hibernate 20 to 40 cm below the mud. At this time, winter protection work must be done. The main method is to drain the pool water and keep the soil moist and clean. In the rainy days, we must do a good job of drainage work, so that there is no water in the pool. During hibernation, do not walk around or accumulate heavy objects in Dianchi, so as to avoid compaction of underground tunnels, resulting in blockage of ventilation and affecting the respiration of Astragalus. Generally speaking, it is not easy to use the deep water for winter because it is easy to manage and easy to catch.
5. Raise the eel
The arrest of the elk is generally around the Spring Festival. Before catching, remove debris and mud from the pool. If the pond mud is hard, it can be soaked and softened by water injection before capturing. When catching, you can first clear the mud from a pool corner outside the pool and then use both hands to turn the mud to capture. It is not advisable to dig with sharp iron and avoid damaging the carcass. At the end, all the remaining soil is cleared out for use as a fertilizer, and the soil will be replaced when it is reared or raised in the coming year. The captured yellow cockroach must be rinsed with water and then kept in a container such as a water tank. The water should be changed 2 or 3 times a day until the food in the body of the cockroach is discharged. At the beginning of the holding period and after 24 hours, 300,000 units of penicillin were administered. At the same time, every 3 to 4 hours, a hand or a small net was inserted into the bottom of the container to stir upwards to prevent the weak jaundice from dying at the bottom for a long time.
Dried fruit products as the name implies, dried fruit products are pre-treated fruits after selection, washing and dehydration to the water content of 15 ~ 25% products. The volume of dried fruit is about 11 ~ 31% of that of Fresh Fruit, and the weight is about 10 ~ 25% of that of fresh fruit, so it can significantly save the cost of packaging, storage and transportation, and it is easy to eat and carry. Common dried fruits are raisins, red dates, dried mango, dried kiwi, dried strawberry and so on.
