Weather characteristics and agricultural impacts of the past week:
In the past week (November 26 to December 2), except for most of Northeast China, most of Inner Mongolia, central and northern North China, northern Shaanxi, and northeast Huanghuai, the average temperature was 1 to 4 lower than that of the same period in normal years, and the average temperature in most of the rest of the country was close to normal or 1 to 4 higher, of which 4 to 6 higher in northern Xinjiang.
The southeastern part of Jilin, the northern part of the Shandong Peninsula, the southwestern part of Chongqing, the central part of Guizhou, the southern part of Guangxi, the northern part of Guangdong and most parts of Hainan received 5 to 25 mm of precipitation, which was close to the same period of the year or more than 3 to 1 timesMost of the rest of the country received less than 5 mm of precipitation or no precipitation.
The sunshine hours in most rural areas of the country are close to the same period of the year or more, among which the sunshine in southeastern Gansu, central Shaanxi, central and southern North China, western Huanghuai, most of Jianghuai, southern and eastern Jiangnan, and eastern southwest China is 5 to 2 times more sunshine.
Under the influence of cold air from the 26th to the 28th and from the 29th to the 30th, the temperature in most parts of the north was lower than that of the same period in normal years, and snowfall occurred in the central part of Inner Mongolia, the eastern part of the Northeast region and the northern part of the Shandong Peninsula, which had a slight adverse impact on the agricultural production of facilitiesThe cold air cooling was conducive to inhibiting the vigorous growth of some winter wheat and the cold resistance exercise of most winter wheat, but it was slightly unfavorable to the transformation and upgrading of some late weak seedlingsThe temperature is high and the precipitation is low in most parts of Xinjiang, and the meteorological conditions are favorable for the growth and wintering of winter wheat, facility agriculture and animal husbandry production in most parts of Xinjiang.
In the middle and lower reaches of the Yangtze River and its southern regions, the weather conditions are generally conducive to the growth of winter wheat and rapeseed crops and the transformation and upgrading of seedlings, as well as to the improvement of the quality and timely harvesting of economic forest fruits.
In South China, the temperature is high and the precipitation is low, and the meteorological conditions are conducive to the ripening and harvesting of late rice and other autumn crops, as well as the growth and development of vegetables and fruits.
The eastern part of southwest China has high temperature and more sunshine, and some areas have 5 to 25 mm of precipitation, which helps to replenish soil moisture and is beneficial to the growth of winter wheat and rapeseed seedlingsHowever, there was no precipitation in southwestern Guizhou and southern Sichuan, and the growth of rapeseed, winter wheat and vegetables was slightly affected.
Impact of future weather on agricultural production:
It is expected that in the next 10 days, except for the northeast of North China, the central and southern parts of Northeast China and the eastern part of Inner Mongolia, the average temperature in most of the rest of China is higher than that of the same period in the normal year, of which most of the northwest and southern regions are 2 to 3 higher, and the meteorological conditions are generally conducive to the production of facility agriculture and animal husbandry, the formation of pre-winter seedlings of winter wheat in the north, and the growth of crops and vegetables in the south.
However, on the 4th to 5th, snowfall will fall in most parts of northern Xinjiang, and the temperature will drop by 5 to 8, which will have an adverse impact on facility agriculture, livestock grazing and feeding, and transfer.
From 5 to 6, under the influence of strong cold air, the temperature in most parts of the north will drop by 4 to 8, Inner Mongolia and some areas in the northeast can reach more than 10, accompanied by 4 to 6 northerly winds, 8 to 10 There will also be a cold air affecting most of the central and eastern parts of China, and the windy cooling weather will increase the cost of cold protection and management of facility agriculture, and some fruits and vegetables in areas with high cooling intensity are prone to frost damage.
The soil moisture in most of the northern winter wheat areas is good, and the gradual decrease in temperature is conducive to the cold resistance exercise of winter wheat, and with the decrease of temperature, winter wheat will enter the wintering period from north to south.
In the next 10 days, the temperature in the south will be high, and there will be light to moderate rain in the eastern part of the southwest region, the south of the Yangtze River and the northern part of South ChinaThere is no precipitation in southern Sichuan and southwestern Guizhou, and some farmland is slightly lacking in moisture, which is slightly unfavorable to the growth of autumn-sown crops and vegetables.
Recommendations for agricultural production:
According to the wheat seedling condition and soil moisture in the winter wheat area, seize the pre-winter management window to ensure the formation of strong seedlingsLate weak seedling plots, appropriate topdressing of fast-acting fertilizer, promote the transformation and upgrading of seedlings, strive to strengthen seedlings over winter, and reduce the risk of winter frost damage;For plots with deviation moisture, overwintering water is watered before the soil freezes.
Facility agriculture and animal husbandry in the north have strengthened animal husbandry and facility agriculture insulation, wind and snow prevention, paid close attention to weather changes, overhauled and strengthened sheds in a timely manner before the arrival of windy and snowy weather, pressed the shed film, and improved the disaster resistance of the facilities.
In the southern region, the field management of rapeseed, vegetables and other crops should be strengthened, and vegetables and fruits that meet the harvest standards should be harvested in a timely manner, and storage and transportation should be done wellAt the same time, we should do a good job in the construction of water conservancy in farmland and the storage and conservation of water in reservoirs.
