At present, most of the shed vegetables have already been planted and the seeds have been flowered early. Here, we remind farmers to guard against cold spring weather. In response to the cold in spring, farmers should generally adopt the following countermeasures:
To strengthen the insulation. For vegetables that were planted at the beginning of February and early March, do not remove the agricultural film in the shed prematurely. Vegetables grown at this stage generally have to be installed with sheds and small greenhouses and other layers of agricultural film to keep warm. As the weather turns warm, some vegetable farmers looked at the temperature in the recent period of time is relatively stable. To facilitate the operation, it is necessary to withdraw early. After removing the agricultural film, it is recommended that the vegetable cultivators first remove the small shed inside, leaving the second or even three layers of agricultural film ready for the second half of the year to cover it again. It is also necessary to pay close attention to the weather forecast and wait until the temperature becomes stable before removing it completely. . For the vegetable seedlings that have just been planted, it is advisable to set a small shed of 1 to 2 layers in the arch shed to prevent the spring and cold, and to add grass and grass to the outside of the arch shed to protect the wind from the cold.
Can also be implemented before the cold watering insulation, because the heat capacity of water is large, before the cold watering, can effectively prevent freezing damage. At the same time, the shed can be temporarily covered with wheat straw, straw, etc., but also can be appropriately increased temperature.
To control fertilizer and water, reduce the amount of nitrogen fertilizer, reduce the humidity within the chamber, enhance light and prevent prosperous growth. Use the high temperature during sunny days, strengthen ventilation, cultivate robust plants, implement low-temperature hardening seedlings, and spray cold and antifreeze agents to kill ice crystals and improve cold resistance. For plants or seedlings with prosperous growth, 750-1000 times the amount of auxin can be sprayed to control the growth rate and improve the cold resistance.
If the vegetables that are in flowering state are endangered by the cold, it is necessary to promptly spray 6,000 times more foliar and nuclear acid (Green Wind 95) to mitigate the hazards; if the seedlings just planted are subjected to freezing damage, it is best to apply proper shading. After the time, the foliar spray was applied to love more and nuclear acid to solve the frost damage.
Vaccine For Prevention Of Rabies
Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals
