From yesterday (No. 29), there were obvious winds and cool weather in central and eastern China, and most of them experienced cooling at 6-10 °C. Among them, the central and western parts of Inner Mongolia, the northeastern part of Northwest China, the central and western parts of North China, the central and western parts of Huanghuai, and most of the Jianghuai The temperature drop in some areas such as the northeastern part of the Yangtze River can reach 12~14°C; the north and east coastal areas of the Yellow River have 6~7 northerly winds, and the Huanghuai, Jianghuai and Jiangnan northern areas have 4~6 northerly winds; The local areas of North China, Huanghuai and other places have sand or dusty weather. The cooling effect caused by this cold air process is obvious. Compared with the previous period, the minimum temperature in some areas will reach the lowest value in winter, and the wind is large, the body temperature is low, and some areas will be more severely frozen. Today (30th) night, temperatures in central and northwestern Inner Mongolia, western North China, Huanghuai and other places will fall to the lowest since winter, and the lowest temperature in central Inner Mongolia will reach minus 30 °C to minus 25 °C, compared with the extreme minimum temperature in the previous period. It is also lower by 3 to 4 °C; the minimum temperature in the central and northern Shaanxi and the north-central Shanxi will reach minus 24 ° C to minus 20 ° C, which is 2 to 3 ° C lower than the extreme minimum temperature in the previous period; the minimum temperature in most parts of Huanghuai will reach minus 7 °C ~ minus 11 ° C; the lowest temperature in the western part of Huanghuai is slightly lower than the previous period. From the night of December 31 to the early morning of January 1, 2011, the temperature in the Jianghuai and the northeastern part of the Yangtze River will drop to the lowest value since the beginning of winter. The lowest temperature of 0 °C will be south to the south of the south of the Yangtze River to the northern part of South China. The temperature is generally between minus 7 ° C and minus 5 ° C; the lowest temperature in the northeastern part of the Yangtze River is minus 6 ° C to minus 2 ° C, which is 1 to 2 ° C lower than the previous minimum temperature; the lowest temperature in the central and western parts of the south and south of South China is minus 2 ° C ~ 2 ° C. Winds and winds are likely to cause damage to greenhouses, livestock and poultry houses, etc., and will also affect livestock grazing, pasture transitions, winter lamb production, resulting in livestock feed shortages and high mortality rates. In addition, winter wheat tillers and rapeseed transplanting and The growth of open vegetables, potatoes, tobacco, fruit trees, economic forests, etc. is also unfavorable, which may cause some of the weaker winter wheat, rapeseed and southern cash crops to suffer from freezing damage. However, the snowfall weather in the Shandong Peninsula is favorable for the formation of stable snow cover for winter wheat. All localities should actively adopt measures to prevent cold and freeze, and reduce the impact of cooling on agricultural production. (1) The winter wheat area in the north should do a good job in drought and cold prevention, and cultivate strong seedlings to survive the winter. The wheat fields that have not formed stable snow cover in the north should be repressed, fertilized and covered to ensure the winter and wheat are safely wintered. At the same time, combined with the suppression and application of organic fertilizer to protect the temperature, prevent the freezing and drought disasters from damaging the growth of winter wheat. . In the snow-covered areas, after the snow melts, use the warm and sunny weather to make timely plans, break the knots, make up for the cracks, and increase the temperature and protect the trees, so as to create conditions for the winter wheat to safely winter. (2) The southern region should strengthen field management and promote the steady growth of crops. In areas with conditions in the south, measures such as applying ash, covering straw or film should be adopted to increase soil temperature and prevent freezing disasters; in areas with excessive precipitation, it is necessary to grasp the clearing of the ditch, reduce the soil moisture of the farmland, and avoid the occurrence of wet waterlogging. At the same time, it is necessary to strengthen the management of vegetables and fruit trees. (3) Do a good job in wind and cold protection of facility agriculture and animal husbandry. Greenhouse greenhouses should be reinforced with scaffolding, and thickened coverings and artificial heating in the sheds should be used to keep warm and warm to ensure the normal growth of crops in the greenhouse; fruit trees can be painted with white, trunked or soiled, covered, smoked, etc. Cold-proof and anti-freezing; in the case of snow-falling areas, it is necessary to timely remove snow from greenhouse roofs to prevent damage to the greenhouses; in addition, it is necessary to prepare livestock feeds and do a good job of strengthening and keeping warm.
