Today during the day (11th), affected by cold air, the southeastern part of the country, the eastern part of North China, the eastern part of Huanghuai, some parts of southern China have 4 to 6 °C cooling, and the local area can reach 8 to 10 °C. From 12 to 13 days, affected by another weak cold air, the northwestern region, north China, Huanghuai, Jianghuai, Jiangnan, South China and other places cooled down by 3 to 6 °C, accompanied by 4 to 5 winds. The northern dryland area had a little rain and snow yesterday. Today, it began to face the cooling weather. For the current temperature, the farmers must wait for the daily average temperature to stabilize at 3 °C and then carry out irrigation work to prevent night ground freezing. .
As China is a country with water stress, coupled with the drought in the north of the previous period, the reservoir water or groundwater in some dry areas has been seriously short, and it is difficult for people and livestock to eat water. Therefore, friends of wheat farmers must pay attention to the festival when they return to Qingshui in spring. Water irrigation. After watering, it can be used to improve moisture utilization. It is necessary to pay attention to first planting wheat fields that are severely affected by drought and freezing, and promote water-saving irrigation technology, which is 30 to 40 cubic meters per mu. After watering, the surface moisture should be timely, the board should be broken, the soil should be loosened, and the soil should be warmed. In addition, 10 kg of urea should be applied per mu, and the amount of diammonium phosphate should be increased to promote the secondary root spray. Increase spring tillering and increase tillering rate.
It is estimated that in parts of Shanxi, Hebei, Shandong and other places, there will be 1-3 mm of snowfall on the 12th to 13th; there will be sporadic snow in parts of Beijing, Tianjin and Henan. The wheat farmers in the dry areas need to continue to pay attention to the weather forecast and continue to do a good job in drought-resistant and strong seedlings.
Irrigation in arid wheat areas should strictly control the daily average temperature of 3 °C to prevent frost damage.
