According to the China Weather Network, Beijing has not seen the rain for three or four consecutive months. The winter wheat is seriously deficient in water, and the drinking water of people and animals is difficult. When there are many rains and snows in the southern provinces, precipitation in nine provinces including Shandong, Henan and Hebei The situation continues to be less and the drought is developing rapidly. Meteorologists said that the lack of water vapor conditions in the above areas is the main cause. It is expected that there will be no obvious precipitation in the North China and Huanghuai areas in the next ten days, and the drought will continue.
Drought: direct drought in some parts of Shandong, Shandong Province: Shandong Province: Most droughts in the province exceeded 50 years. “From last year to now, there is no drop of rain in 4 months. The reservoir has also bottomed out. Now I want to pour water and water. No. I lived in my 70s. This drought has been experienced three times, but this time it is the most dry.†Liu Xingde, a villager from Baita Village, Qufu, Shandong, was interviewed by local media and was exposed to the cloud. The 70-year-old man experienced three times. Drought, but this time the most drought. Every day I go to my own wheat field to see that it is a compulsory course. The wheat seedlings are withering day by day. Liu Laohan can only be anxious: "If you can get off the snow before the year, these seedlings will be saved, if there is no rain, no water. Pouring, it is hard to say."
Such a situation can be seen everywhere in Qilu. According to the Shandong Provincial Water Resources Department, except for the northern part of the peninsula, most of the province's drought has been more than 50 years. There are 59.73 million mu of farmland affected by drought, of which 31.83 million mu has been watered. There are still 27.81 million mu of winter wheat. Drought, accounting for 51% of the province's wheat planting area, including 3.73 million mu of heavy drought. Linyi, Heze, Zaozhuang, Jining and Weifang have reached a serious drought level.
Henan: Since the drought area was 15.86 million mu from the wheat planting, the province of Henan Province has been suffering from drought and rain. Since November last year, the precipitation in the whole province has been 86% less than that in the same period of the previous year, which is the lowest in the same period since 1961. For Henan, where the output of wheat accounts for a quarter of the country's “granary of Chinaâ€, this situation is clearly unfavorable.
At present, the drought-affected area of ​​Henan Province is 15.86 million mu, and the heavy drought is 1.67 million mu. In order to ensure food security, Henan Province has invested a total of 210 million yuan in drought relief funds, dispatched 330,000 laborers, and accumulated a total of 17.25 million mu of drought-resistant wheat. Henan Province also issued the first normative regulations on drought resistance, which stipulated that the drought-resistance work should be implemented by the executive head.
Hebei: 3.37 million people have difficulty drinking water. At present, the drought-affected area in Hebei Province has reached 16.15 million mu, of which the winter wheat area is 5.15 million mu. Not only is the crop lacking water, but the difficulty in drinking water for people and animals is also very prominent. According to the survey, there are currently 3.77 million people and 129,500 heads (only) of large livestock in the province due to drought.
According to the Hebei Flood Control and Drought Relief Headquarters, the drought-resistance problem in Hebei is highlighted by the lack of water storage and the drought-resistant water resources. The distribution of water storage in large and medium-sized reservoirs in the province is very uneven. It is concentrated only in a few large reservoirs such as Gangnan, Huangbizhuang and Xiyangyang. Most of the irrigation districts have insufficient water supply or even water supply. In addition, the water table in the province has continued to decline, and nearly 100,000 eye wells in the province have insufficient water or water. To this end, the Water Resources Department of Hebei Province combined with the basic construction of winter farmland water conservancy, increased investment, and strengthened the construction of emergency water source projects.
Experts dispel doubts: less precipitation due to insufficient water vapor conditions. According to the National Climate Center on January 12th, at present, Hebei, Beijing, Tianjin, Henan, Shanxi, Shandong, Anhui, Jiangsu, Hubei and other places have meteorological droughts of varying degrees. Among them, Shandong, Henan and other provinces have experienced moderate to severe drought, and some areas in central Henan and Shandong Bureau have reached the drought level. The drought resistance situation in winter is more severe.
Why did North China, Huanghuai and other places continue to be dry and drier when the rain hits the south? Is this weather abnormal?
Li Xiaoquan, chief weather expert of China Weather Network, explained that the recent precipitation in the south is due to the fact that the southwest warm and humid airflow from the Bay of Bengal has delivered abundant water vapor, while the two relatively rainy regions in the north and the water vapor source in Xinjiang are the Sea of ​​Japan. And Central Asia.
“The North China Plain, the middle and lower reaches of the Yellow River and the Huaihe River Basin cannot be seen on both sides. These areas are controlled by the northwest airflow during cold air intrusion, relatively dry, and the water vapor conditions are very poor, while the southwestern warm and humid airflow forces in the south are not enough to go deeper. The northern region. Such atmospheric circulation has been maintained for a long time, resulting in drought and less rain in North China and Huanghuai areas," Li Xiaoquan said.
Experts said that the North China and Huanghuai regions are monsoon climate zones, with less precipitation in winter, which is a normal climate phenomenon. However, this year is less than average on average, and there is no precipitation for a long time. This situation is relatively rare.
Future development: North China Huanghuai and other places still have no obvious precipitation. The Central Meteorological Observatory predicts that due to the influence of cold air, the southern region will usher in two more obvious precipitation processes in the next ten days.
However, in the north due to the lack of warm and humid airflow, the cold air is still the main wind in the north. It is expected that in the next ten days, most of the northern part of the country will be dry and cold, and the temperature will be low. There will be no obvious precipitation process in the meteorological arid areas of North China and Huanghuai, and the drought will continue.
Agro-gas experts suggest that the meteorological arid area should strengthen the management of winter wheat fields. Winter wheat area should timely check the grievances and seedlings, and classify and manage according to specific conditions. For the wheat fields that have been poured over the winter water, timely cut the loose soil, remove the knots, and ventilate and protect the ground to raise the ground temperature; the areas with irrigation conditions should be finely watered or sprinkled with small water in the afternoon; no irrigation conditions or cold weather is not suitable In areas irrigated, measures such as suppression, fertilization and cover may be used to protect against drought; for wheat fields with sufficient bottom, normal growth or high growth, watering should be postponed, moderate tillage or suppression should be carried out to inhibit excessive growth of aboveground parts and ensure winter wheat formation. Strong seedlings and safe wintering.
At the same time, we must do a good job in water storage and drought prevention and construction of farmland water conservancy infrastructure. In North China, Huanghuai and northern Jianghuai, it is necessary to take measures to protect the winter and spring drought. All localities should also do a good job in the construction of farmland water conservancy infrastructure, repair, improve and support water conservancy facilities to enhance agricultural disaster prevention and resilience.
