Spring farming should pay attention to the problem In the spring of March, the weather is getting warmer and it is a good season for farming. However, as the temperature gradually rises, various germs will multiply. After wintering of livestock and poultry, the body's resistance to disease has weakened. If the disinfection is not complete during the breeding process, mismanagement can easily lead to diseases and reduce the breeding efficiency. Then, what problems should be paid attention to after breeding in spring? 1. Repair the house and do a good job of disinfection Keeping the house warm, dry, and ventilated, doing a good job in housing hygiene, often disinfecting the house, and eliminating the living environment of the germs are an important part of doing a good job of spring culture. In the early spring, the weather in March is volatile and the temperature difference between day and night is relatively large. Therefore, it is particularly important to maintain a warm environment, dry and clean environment, and smooth air, and create a small environment conducive to the growth and development of livestock and poultry. Thoroughly clean the pens before disinfection, and then use 20% to 30% of lime milk or 20% of ash or 2% to 3% of fire alkali solution to spray and brush the floor, walls and surrounding areas of the enclosure. After washing with 3% to 5% of the water of the Soviet Union, and then rinse with water. 2. Strengthen epidemic prevention and pay attention to nutrition In the spring, we must guard against the occurrence of various infectious diseases. Strictly follow the immunization procedures to do a good job of immunization of livestock and poultry. Once an epidemic is found, it must immediately report it to the local epidemic prevention department and take measures such as isolation, blockade and disinfection, and handle the dead and dead carcass as required. If there is an outbreak in the surrounding areas, in addition to doing a good job in the disinfection of sheds, foreign personnel and vehicles should be strictly prohibited from entering the breeding grounds, and their vehicles and personnel must be completely disinfected after returning from the epidemic areas. At the same time, the level of nutrition also has a major impact on the health of livestock and poultry. High-level nutrient supply can meet the nutritional needs of livestock and poultry, ensure that livestock and poultry have a good body condition, and can effectively improve the ability of the carcass to resist disease. Therefore, in the production of livestock and poultry should be based on different stages of growth, scientific formula, feeding different nutritional standards of feed. 3. Fine management, scientific feeding The current feeding methods are mainly small-scale and free-range breeding. Animal animal epidemic prevention barriers are backward, and commercialization and marketization are low. Conditional farmers must adhere to self-cultivation and self-cultivation, and develop a modest scale. If it is really necessary to import livestock and poultry from foreign fields, they must be quarantined strictly and quarantined for a certain period of time in accordance with regulations before they can be reared in groups. Usually provide sufficient clean drinking water, keep the pens dry, maintain a reasonable feeding density, and reduce the emergency factors. Ensure adequate nutrition and enhance livestock disease resistance. 4. Do a good job of prevention and treatment of common diseases There are many animal diseases that can easily occur in the spring. The most common are diarrheal diseases, mycoplasma pneumonia, and flu. Once the above-mentioned common diseases occur, they must be correctly identified before they can be treated symptomatically. Do not ignore the epidemic prevention of common epidemic diseases (such as chicken Newcastle disease, swine fever, etc.) at ordinary times. Newcastle disease is still one of the most common diseases that endanger the chicken industry, and it is also a secondary or concomitant disease of certain diseases. First of all, do a good job in epidemic prevention and prevention work: For influenza, timely injections of inactivated vaccines for influenza are mainly used; swine industry should consider swine fever as a priority for prevention. Spring pond management points In the spring of March, Jiangnan grass grows, and the gang fights indiscriminately. After a period of pond clearing, the culture pond began a new production. Farmers should pay attention to the following points in the management of spring culture ponds: First, according to local conditions, control density. For seawater ponds, where fish, shrimp, crabs and shellfish are mainly mixed, local conditions should be adopted to control the stocking density. The first is that prawn stocking should be 10,000 mu per mu, while ponds with white tailed prawn rearing should control the density according to seawater salinity, and the salinity should be 6%. ~15%. It controls 40,000 or less per acre, depending on the situation of seedlings to control the increase or decrease of feeding, salinity 15%. The control density of the above ponds is more suitable for 20,000 or so; second, the crab salinity is 6%. ~15%. Acre stocking 800 to 1000, special breeding doubled, salinity at 15%. Above appropriate reduction; Third, the overall area of ​​shellfish culture should account for less than 30% of the whole pond water, salinity of 18%. Above, acre stocked 200,000 to 400,000 grains with a salinity of 10%. ~18%. Acre stocked 100,000 to 150,000 tablets, with a salinity of 10%. The best of the following is not stocked. Second, the amount of force, choose a good variety. At present, the high demand for high-grade aquatic products is increasing, such as famous fish products such as groupers, lobsters, and silkworms. However, these species are expensive and the cost of breeding is high. Second, farmers are not familiar with these breeds. It is well understood that technological risks are large, and third, the market conditions of new varieties have changed greatly. Market risks such as large yellow croaker, gums, turbot, and white prawn are high. Therefore, farmers need to use their own economic and technical strengths and capabilities to choose the best varieties. It is recommended that the nearest source be based on traditional products, such as small white shrimp, blue crab, crab, mud loquat, quail, etc. Proper new species development will do more with less. Third, daily management, careful and careful. In the spring, basically, seedlings are mainly planted. If the seedlings are released, it seems to be doing nothing, but it is not. First, after the seedlings are released, the survival rate of the seedlings should be checked, and the seedlings should be dealt with earlier in time. The second is to observe the growth conditions of bait feeding, spring is the season of recovery of all things, but also the growth of algae shellfish, on the one hand based on actual needs to prepare adequate high-quality bait, such as blue crabs after the formation of weakness in high quality food such as blue , snails, small junk fish and so on to supplement the nutrition; the other hand, while feeding and increasing fertilizer, pay attention to water quality changes, such as application of compound fertilizer to improve fertility culture algae rich shellfish bait, but this method is easy to make the pond nitrogen and phosphorus exceeded Should not be used more often, it is recommended to use fish and other aquatic drugs with algae. The third is to conduct culture records, standardize the operation, fill in the culture log, one can do accounts, two can be controlled analysis, three can enrich the daily production of aquaculture production. Drought Prevention and Control Techniques in Arid Regions At present, it is necessary to do a good job of prevention and control of vegetables, orchards, sugarcane pests and diseases, as well as rodent pests, spring seed sow disinfection. (i) Scientific irrigation and control of field water balance. When irrigation (leaching) water is used for drought protection and seedling protection, it is necessary to prevent long-term accumulation of water in the ditch or car, control the balance of moisture, and reduce the favorable conditions for the occurrence of germs. Drip irrigation may be used in places where conditions permit. (b) Strengthen field management. The orchards and ratoon cane are used in conjunction with fertilization to deepen the land and eliminate overwintering pests such as cockroaches, beetles, golden needles, ground tigers, black caterpillars, and roundworms. Citrus garden complexes with flowers before cutting, cutting off dead branches, eggs, such as ulcers, anthrax branches, damaging branches of Tianni and so on. Severe vegetable and mulberry fields where pests and diseases have occurred must also promptly remove pests and leaves to reduce the number of insects in the field. (C) promote the application of new technologies for physical prevention and control. Application of frequency-type insecticidal lamp to trap and kill locusts, long-horned beetles, and sugarcane turtles, application of colored worm boards to control locusts, thrips, and sex attractants to trap and kill vegetable pests such as diamondback moth, Spodoptera litura, and fruit-bearing fruit flies. "Technology controls rodents. (d) Spring irrigation. The conditional areas are held in the 5th to 7th days before overwintering maggot emergence, flooding inundates the rice roots for 3 days, and the winter cultivating green fertilization fields are irrigated for 2 to 3 times. Effectively reduce the nuclear base number of rice sheath blight. (e) Chemical control. Combining with the actual situation in the local area, according to the pest information and prevention advice of the local agricultural plant protection (agrotechnical) sector or the prevention and control under the guidance of the plant protection technicians, select appropriate counterparts, timely spray pesticides for high-efficiency pesticides, pay attention to scientific and safe use of drugs, and prohibit the use of countries. Highly toxic pesticides that are explicitly prohibited. JIANGMEN EASY TECHNOLOGY CO.,LTD , https://www.easylife-tech.com
