Most of China's central and northern regions are the drying and storage stages of autumn crops. In the eastern part of the southwestern region, the eastern part of the Yangtze River and the eastern part of the Yangtze River, and the eastern part of the south of the Yangtze River, the rice is harvested and aired. The cotton in the northwest, north China, Huanghuai, Jianghuai, Jianghan and Jiangnan areas continue to be harvested. Some parts of the central and southern parts of North China, Huanghuai and Northwest China Apple picking, sweet potato harvesting in parts of central and southern China, Huanghuai, Jianghuai, etc., citrus, banana and other fruit picking in some parts of the south; rapeseed in parts of the southwestern part of the southeast, Jiangnan, Jianghuai, Jianghan, southeastern part of the northwest Sowing or transplanting, sowing winter wheat in the southwestern region, Jianghan, Jianghuai and other places. Water and fertilizer management and pest control of cotton, open field vegetables, facility agriculture and southern double-season late rice, sugar cane, sweet potato, autumn sowing crops and fruits; disaster prevention, disaster relief or post-disaster recovery and reconstruction work in some or part of the region.
This week's focus is on
According to the characteristics of the previous weather and climate change and the current agricultural conditions and future weather changes, we should pay attention to:
1. It is predicted that the strong cold air that hit China in the last week will continue to move eastward and southward in the early part of this week. The temperature in the southeastern part of Northeast China, the southern part of North China, the Huanghuai, Jianghuai, Jianghan, Jiangnan, South China, and southeastern southwestern regions It will fall by 6-8 degrees Celsius, in which parts of Huanghuai East, eastern Jianghuai, eastern Jiangnan, southern Jianghan, eastern Guizhou, and western Hunan have cooled by 10 degrees Celsius. After the cold air strikes, the North China Plain and Huanghuai District The minimum temperature will drop to 0-5 degrees Celsius, the lowest temperature in the Jianghuai, Hanshui River Basin, the central and northern parts of the Jiangnan area, and the Yunnan-Guizhou Plateau will be 6-8 degrees Celsius, south-central Shaanxi, Beijing-Tianjin, central and southern Hebei, south-central Shanxi, Shandong, Henan. Early frost will occur in parts of northern Anhui, northern Jiangsu, etc.; most of the above areas have 4-6 northerly winds and gusts 7; central and eastern Gansu, northern and eastern Qinghai, northwestern Sichuan, northeastern Inner Mongolia In the eastern and northern parts of the Northeast, there will be small to moderate rain (snow) or sleet, partial heavy snow, southwestern Shaanxi, western Hubei and most of southern Jiangnan, and eastern China. Therefore, greenhouse facilities, pastoral grazing, transportation, etc. should be well protected against wind or snow, and the pre-frost flowers of cotton should be plucked. Some areas in the southeastern part of the country, central and southern North China, Huanghuai, and the northwestern part of the country have matured yet. Chinese cabbage, sweet potatoes, apples, etc. should be harvested in time (digging, mining) before the frost or frost, to avoid low temperature, frost and snow damage.
The northern winter wheat producing area should strengthen the management of water and fertilizer in the field according to the conditions of the seedlings and lyrics, timely suppress and plan the sputum, protect the stagnation and freeze, and timely control the pests and diseases to ensure the strong seedlings before winter.
Jianghuai, Jianghan, Jiangnan, and the southwestern part of the country should pay close attention to land reclamation and land preparation, and apply sufficient base fertilizer. According to different lyrics, grab (making, dispersing) hoe sowing winter wheat, rapeseed (live) or transplanting rape (transplanting varieties), etc. To cultivate strong seedlings.
In the south of the Yangtze River and South China, it is necessary to do the lodging prevention work of late rice or sugar cane.
Gansu, Qinghai, Ningxia and other provinces and regions should take advantage of the rain (snow) (including last week's precipitation) to increase the chances of timely flooding, honing, etc. in the spring of next year to protect the sputum and storage, for the next spring Sowing lays the foundation.
The majority of farmers and friends should add clothing according to the weather changes, prevent cold and keep warm, prevent colds and other diseases;
2. It is predicted that due to the influence of the strong cold air in the south of the Zhou Dynasty, the winds of the rivers and lakes in Huanghuai, Jianghuai, Jianghan and Jiangnan will reach 5-7 grade northerly winds and gusts up to 8 grades; In the Yellow Sea, the East China Sea, the Taiwan Strait, and the east side of Taiwan, there are 8-9 northeast winds and gusts 10-11. There are 7-9 northeast winds in the northern part of the South China Sea and 6-8 northeast winds in the Beibu Gulf. Therefore, ships sailing and operating in rivers, lakes and seas should be prepared to prevent casualties and property losses;
3. It is predicted that there will be moderate rain and partial heavy rain in some areas in the eastern part of the southwestern region during the rainy weather. The interception of surface runoff after the rain should be done, and the water storage capacity of the mountain ponds, reservoirs, and leeches should be increased, and water resources should be production and living of agricultural production and living in autumn and winter and next spring;
4. The autumn season is the season of fog in China. During the week, some areas in the southern part of North China, Huanghuai, Jianghuai, Jianghan, Jiangnan and other places may still have fog weather with visibility within 1000 meters. Road transportation, rivers and lakes, water surface boating, etc. should be prevented to prevent casualties. And property damage;
5. At present, the autumn crops in the central and northern regions have entered the drying and storage stage. The double-season late rice, sweet potato and early autumn sowing crops (corn, soybean, sweet potato, etc.) in the southern region are in the final stage of growth, and the winter wheat in the northern winter wheat region is in the seedling stage. In the growth stage, sowing, emergence or transplanting of rapeseed and green manure in the southern region, production of vegetables and fruits, fruits and flowers in open fields, and accumulation, coloring or harvesting of fruit in some areas. Therefore, while continuing to prevent all possible meteorological disasters, we should strengthen scientific field management and monitoring and control of pests and diseases based on weather changes and crop growth processes, timely harvesting, and returning to the warehouse to ensure full In the year of agriculture, there is a good harvest and balanced production of vegetables to meet market demand, and to cultivate strong seedlings such as winter wheat and rapeseed in autumn, laying a foundation for the harvest of grain and oil in the summer of next year
6. Divided from the climatic law. After the fall, with the decrease of precipitation, the air humidity decreases, the number of windy days increases, and the moisture content of the litter and leaves in forests and pastures decreases, causing forest and grassland fire risks. The weather level is high. Therefore, it is necessary to strengthen safety and fire prevention work to prevent fires in forests and grasslands.
This week's weather conditions
This week (October 25-31, 2010), the strong cold air that hit China last week will continue to move southward in the early part of this week. Most of the central and southern parts will have a cooling of 6-8 degrees Celsius and 4- 6 The northerly winds, the winds in the eastern and southern seas will reach 7-9, the gusts 10-11 northeast winds, the first frost will appear in the southern part of North China, Huanghuai, and the southeastern part of the northwest. More rainy weather in the eastern part of the Southwest.
