China News Service, March 3, According to the website of the Ministry of Agriculture and Rural Affairs, on March 2, the Ministry of Agriculture and Rural Affairs issued a notice requesting all agricultural and rural departments to do a good job in the prevention of "spring cold", implement active disaster prevention and scientific disaster prevention measures, and work hard. Reduce the impact of disasters and ensure the safety of agricultural production.
Since February, the temperature in the northern winter wheat area has been 4.5℃ higher, and the growth of crops is faster than normal. At present, winter wheat in the north has fully turned green. It is expected to enter the jointing and booting stage in mid-March, rape and fruit trees will gradually enter the flowering stage, and large-scale vegetable seedling transplant , The cold resistance rapidly declines.
The Meteorological Department predicts that there will be three cold air activities in March. Jointing wheat, flowering rapeseed, fruit tree flower buds and vegetable seedlings will have a significant increase in the chances of freezing damage caused by "cold spring".
The specific prevention work includes four aspects: strengthening organization and leadership, strengthening monitoring and early warning, scientific and effective response, and precise guidance services.
Strengthening organization and leadership: agricultural and rural departments at all levels must focus on ensuring the stable development of food and agriculture, based on disaster resistance and harvest, consciously taking prevention of "spring cold" as an important task for current agricultural production, extensive mobilization, and active scientific response. Implement detailed defensive measures, ensure that responsibilities, materials, and technologies are in place, and strive to have a good harvest of summer grains, and lay a good foundation for ensuring the stable development of food and agriculture throughout the year.
Strengthen monitoring and early warning: strengthen communication and consultation with the meteorological department, pay close attention to weather changes, schedule cooling conditions in a timely manner, scientifically judge the impact of cold air, release early warning information in time, initiate emergency response in time, and implement defensive measures early.
During the period of the cold wave, emergency duty should be strengthened, and the disaster daily report system should be activated to reflect the disaster situation and the progress of the cold and frost protection work in a timely manner.
Scientific and effective response: The northern winter wheat area should organize farmers to topdress and water according to local conditions, hoe to suppress, spray chemical control agents, promote the transformation and upgrade of seedling conditions, and improve the ability to resist freezing.
Before the cold wave, the land with insufficient moisture should be irrigated in time to adjust the ground temperature to prevent freezing damage. After the cold wave, nitrogen fertilizer, foliar fertilizer and growth regulators should be applied in time to reduce the impact of freezing damage.
In the southern region, it is necessary to strengthen the management of rice seedling fields to prevent low temperature and rain and lack of sunshine leading to rotten seedlings; strengthen rape field management, and spray boron fertilizers, phosphorus and potassium fertilizers at appropriate times to improve stress resistance.
The waterlogging field shall be cleared in time, drained and waterlogged.
Early implementation of anti-freezing measures for open-field vegetables and fruit trees, reinforcement of greenhouses, and timely topdressing of contaminated soil after the cold wave, to promote the recovery of crops.
In terms of precise guidance services: formulate and improve the technical plan for preventing "spring cold" field management as early as possible, and make full use of media such as radio, television, newspapers, mobile phones, and the Internet to publicize measures to prevent freezing damage. Organize cadres and technicians to go deep into the fields, strengthen classification guidance, and help farmers implement key measures to prevent frost and cold according to location, time and seedling. Practically achieve services to households and measures to fields. Strengthen the adjustment and transportation of production materials such as seeds (seedlings) for disaster relief, fertilizers, pesticides, etc., to ensure the demand for disaster relief materials.
