As the temperature continues to drop, recently, the city's agriculture and fishery departments issued a cold prevention reminder and sent technicians to the fields and aquaculture areas to guide the work.

At present, the Municipal Agricultural Bureau has issued a circular to the agricultural departments of various counties (cities) and districts, demanding that according to the disaster prevention and reduction plan, scientific dispatch of manpower and material resources to achieve the "three places" of personnel, materials, and technology, and strive to reduce the losses caused by disasters to a minimum. Agricultural experts have gone to various counties (cities) to carry out supervision and guidance on the current agricultural anti-cold and anti-freezing work.

Li Wu, head of the planting Department of the Municipal Bureau of Agriculture, reminded: before the cold (freezing) damage comes, all kinds of growers should take measures such as irrigation to keep warm, cover grass to protect seedlings, smoke to increase temperature, and bagging to protect fruit, so as to reduce the harm. Measures such as plastic film mulching and straw mulching can be taken to prevent the damage of winter potato, and spring potato can be sown after warming up. Early-maturing loquat and other fruit trees are easy to be frozen, in addition to clearing the garden, cultivating soil, brushing the trunk and other work, but also take timely smoking, fruit bagging and other measures to prevent the effects of low temperature. Vegetable production can adopt measures such as mulching with plastic film or rice straw, increasing application of hot phosphorus and potassium fertilizer, spraying cold protection agent, etc.; protected vegetables should pay attention to strengthening the shed, paying attention to moderate ventilation during the day, good heat preservation at night, and electric heating where possible.

In the aspect of preventing cold and freezing in animal husbandry, attention should be paid to the maintenance of livestock and poultry houses and power supply systems to ensure power supply and maintain the temperature of the houses; pig and cattle barns should be thickened to keep dry and warm; feed (grass) and drinking water should be provided; and energy feeds such as corn should be appropriately increased. At the same time, we should pay close attention to the prevention of epidemic diseases and ensure the safety of animal husbandry production.

The vast number of farmers should do a good job in the reinforcement of facility sheds and livestock and poultry houses in advance, and in areas where snow occurs, they should promptly clear the snow cover of facilities sheds and livestock and poultry houses; after the weather warms up, they should pay attention to the prevention and control of diseases and insect pests.

The fishery department of our city will organize experts to go to various counties (cities) to guide farmers to do a good job of heat preservation of aquaculture water and prevention of infectious diseases. Experts remind: artificial pond breeds that are vulnerable to freezing damage should be kept warm by setting up sheds as far as possible. Natural ponds should appropriately raise the water level and increase the water storage capacity of ponds to avoid large area frostbite and frostbite to death of farmed organisms. In terms of cage culture, the cage can be sunk as far as possible to maintain a water depth of less than 2 meters, and breeds and parents that can not improve anti-freezing conditions should be transferred to land culture in time. Parents of large-scale farmed varieties should do a good job in seed conservation and cultivation to ensure that there are sufficient parents and seedlings in aquaculture production in the coming year. The aquaculture products that are about to meet the commodity specifications will be caught in time, sold and put on the market. At the same time, it is necessary to prevent the occurrence of water mildew, melon disease and bacterial diseases, and do a good job in water quality improvement, regulation and disinfection.
