In the past week, the temperature across the country has been significantly high, and significant precipitation has generally occurred in the main winter wheat producing areas, which is conducive to winter wheat overwintering. At present, the 0° isotherm is close to the line of the Yangtze River and the Huai River, and the north generally enters winter. Residents in all parts of the country should take precautions against the cold and keep warm, and strengthen the prevention of respiratory diseases.
2. Sub-regionsAgrometeorological analysis
Northeast and eastern Inner MongoliaAgricultural areaMinimum temperatures generally drop below -32°C in the eastern region;The temperature is low, and the rest of the regions are stable and high, among them, the precipitation in the north and south of Jilin and Heilongjiang is less, and the temperature is high, which is conducive to the sales of corn, rice and soybeans, and the market is increasing, which makes the grain in these areas appear downward pressure. At present, the three staple grains** are still seriously low, which has a serious negative impact on the economic development of the agricultural areas in Northeast China. At present, the phenomenon of young people begging together in some tunzi in Northeast China shows that a large number of labor and employment shifts to rural areas last year brought about social instability in rural areas, and it needs to be paid close attention to.
Ecological and agricultural areas of Xinjiang and the Qinghai-Tibet Plateau: The temperature in northern Xinjiang is low, and there is a lot of precipitation, which has an obvious negative impact on logisticsThere is no precipitation in southern Xinjiang and the temperature is on the high side, which is conducive to the purchase and sale of grain and crops, and Xinjiang should do a good job in providing logistical support for commodities to go out of Xinjiang to ensure that agricultural products can be transformed into residents' income and local consumption growth in Xinjiang. Tibetan Plateau regionThere is more precipitation and higher temperatures in the southern region.
Northwest and North China agricultural areasPrecipitation occurred in most areas, and the soil moisture was good, which was conducive to the overwintering of winter wheat, but the temperature was still high, and the current temperature dropped to -8 °C, and the winter wheat entered the wintering weather.
Huanghuai, Jianghuai andHanshui Basin: Precipitation occurs in most areas, although the minimum stability drops below 0 °C, but the current temperature is high, pay attention to prevent the occurrence of the phenomenon of vigorous growth before winter, and there is a large range of soil moisture deficiency in the Jianghuai region.
The ecological damage is serious, the ecological construction is accelerated in winter, and the resumption of navigation, navigation, widening and extension of the Changhong Canal in the southern part of the Huaihe River Basin and the water transport channel Changhong Canal are of great significance to promote the integrated development of the Yangtze River Delta economy and the Central Plains Economic Zone, which is the key and effective measure to promote the balanced development of China's regional economy, and it is hoped that it will be implemented as soon as possible and achieve economic recovery as soon as possible.
Jiangnan and South China Agricultural Areas:Temperatures continue to be high in the region, with some precipitation in the south, but significantly less. In winter, we should make full use of the current lack of rain to do a good job in the construction of water conservancy projects, strengthen the construction of ecological wetlands, and improve the living environment of human beings.
Southwest Agricultural ZoneThere are large arid areas in this region, and there is a large range of meteorological drought in the central and eastern regions of the Yunnan-Guizhou Plateau.
Fourth, the week ahead**(
In the coming week, the cumulative precipitation in northwest Xinjiang, the eastern part of Northeast China, Jianghuai, Jiangnan, South China and the eastern part of Southwest China will be 03～1.5mm。After the 19th, the precipitation will weaken significantly in most parts of the country. Affected by the strong cold wave and the subsequent cold air, except for the Qinghai-Tibet Plateau and Yunnan, the average temperature in most parts of China is lower than that of the same period in normal years2 4, and the average temperature in North China, Northeast China, Huanghuai, Jianghuai, Jianghan and Jiangnan is more than 6. Precipitation and low temperatures have accelerated the transition into the overwintering period, which is conducive to agricultural production in the coming year.
The scope of meteorological drought in southwest China has expanded, the degree has weakened, and the meteorological drought in the rest of the region has been basically eliminated, and the precipitation is conducive to the development of crops in the field in winter, but more precipitation has an obvious negative impact on the circulation of agricultural products, making agricultural products produce more.
Drought in soil monitoring occurred only in the southwest region, while the rest of the region had good soil moisture, which was conducive to agricultural production and overwintering of crops in the field. In autumn, winter and spring, the Huang-Huai-Hai Agricultural Zone should actively produce farmland and water conservancy construction, especially the Huaihe River Basin, which should be accelerated to promote the development of the Central Plains Economic Zone together with the main stream of the Huaihe River and the Changhong Canal of the Shaying River.
There was more precipitation in the northwest and southwest of North China, the southwest of Southwest China, and the eastern and southern parts of the Tibetan Plateau.
The precipitation in the central and eastern parts of the Loess Plateau in the Huang-Huai-Hai region of the eastern region is more than 10 mm, of which the precipitation along the Huai River is more than 50 mm. As the core area of winter wheat, precipitation water is responsible for the overwintering development of winter wheat.
The general temperature in the north of the Qinling Mountains and the Huaihe River dropped to below 0 °C, the average daily temperature in the Huanghuai and Weishui rivers dropped to below -4 °C, the northern region generally entered the winter, the winter wheat generally entered the wintering period, and the temperature in Inner Mongolia, Heilongjiang and northern Xinjiang dropped to below -20 °C.
Compared with the same period in history, the temperature in the northern part of Northeast China and the northern part of Xinjiang is lower, and the temperature in most other areas is significantly higher. In particular, the temperature in some areas south of the Yangtze River is 4-6°C higher, especially in the central and eastern parts of the Yunnan-Guizhou Plateau, which is above 6°C.
In the face of rising global temperature, accelerating the construction of cross-basin water diversion projects and effectively regulating the extreme high levels in summer will play a key role in stabilizing the regional ecology, ensuring the living space of the Chinese nation, and enhancing the potential of the economic and social development of the Chinese nation. More importantly, through the construction of cross-basin ecological projects, the level of agricultural output can be greatly improved, and the carbon sink and oxygen and water vapor release of agricultural production will be accelerated, which is the most critical measure to effectively regulate the regional ecological environment.
At present, the carbon sink of industrial production and its reduction of carbon emissions are simply not the same as the carbon sink of agricultural production, and the real carbon sink activities of human beings can only be greatly improved by promoting agricultural productionOnly by improving agricultural production capacity and increasing the output of agricultural and forestry products through the construction of ecological engineering can we achieve the goal of human carbon emissions.
This week, the minimum temperature in the northern part of Northeast China and northern Xinjiang dropped to an extremely low temperature of below -32°C, and the minimum temperature in North China and the northern part of Northwest China was below -20°C. The temperature of the Tibetan Plateau is significantly higher than that of the same period in history.
The maximum temperature in most parts of the country is above 8 °C, of which the maximum temperature in Lingnan is still above 28 °C, and the temperature gap between the north and south reaches more than 30 °C.
