This week's main agricultural activities
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 southern part 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 picked, and parts of the central and southern parts of North China, Huanghuai and Northwest China. Apple picking, picking of citrus, banana and other fruits in parts of the south; sowing or transplanting of rapeseed in parts of the southwestern part of the southwest and Jiangnan, and sowing of winter wheat in the eastern part of the southwestern region. Water-fertilizer management and pest control of winter wheat, rapeseed and other autumn-sown crops, open field vegetables, facility agriculture and southern double-season late rice, sugar cane and fruits; farmland water conservancy basic construction and local area disaster relief, disaster relief or post-disaster recovery and reconstruction work and many more.
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 there will be more rainy (snow) days in the eastern part of the Qinghai-Tibet Plateau from the eastern part of the Qinghai-Tibet Plateau to the eastern part of the southwestern part of the country, and some areas such as central and eastern Tibet, southeastern Qinghai, northern Sichuan Plateau and central Gansu will have moderate to heavy snow or rain. There is moderate rain in some areas such as Sichuan and Yunnan. In the alpine pastoral area, it is necessary to strengthen the cold and warmth of livestock and the transportation and reserve of forage materials to prevent the death of young animals, weak animals and sick animals. In areas such as Sichuan, Chongqing, Yunnan, Guizhou and other provinces where the soil is too wet, it is necessary to clear the ditch and spread the ditch in time to ensure the smooth transplanting of rapeseed and timely sowing of winter wheat, silkworm peas, etc., and to do the surface runoff after rainfall. To impede storage, increase the storage capacity of mountain ponds, reservoirs, leeches, winter paddy fields, etc., and reserve water resources for water production in winter and spring, agricultural production and living;
2. It is predicted that there will be more winds in the eastern and northeastern regions of the North China during the week, and the temperature fluctuations will change greatly. The early and late weeks will be affected by the obvious cold air, and the temperature will drop by 4-8 degrees Celsius. It is about 10 degrees Celsius and is accompanied by a northerly wind of 4-6 grades. Rain and snow will appear in some areas on weekends. Facility agriculture should do a good job of wind-proof reinforcement, heat preservation and anti-freeze work. The pastoral area should do a good job in preventing cold and wind prevention of livestock, and pay close attention to the weather before freezing and sealing, and do a good job in the construction of farmland water conservancy projects such as grain drying, storage and autumn land preparation. Friends of farmers and herdsmen to the weather changes, time to add clothing, cold and warm, prevent colds and other diseases, central and northern coal-fired heating and herdsmen to pay attention to indoor ventilation, prevention of gas poisoning;
3. It is predicted that the weather in the central and southern parts of North China, Huanghuai, the eastern part of the northwestern region, the Jianghuai, Jianghan, Jiangnan, and southern China will be sunny to cloudy, and the temperature will change more smoothly.
According to the situation of seedlings and lyrics, winter wheat should strengthen the management of water and fertilizer in the field, timely suppress, plan and protect the roots, promote roots and tillers, timely control pests and diseases, and ensure the strong seedlings before winter, laying the foundation for the harvest of summer grain next year.
The harvesting of mature late rice and the finishing work of one season of rice harvesting should be carried out, and the cotton that has been cracked and the unriped apples, citrus, bananas, etc. should be picked.
Strengthen water and fertilizer management and pest control of Chinese cabbage and other open vegetables and greenhouse vegetables in the late growth stage.
In the late-season paddy field in South China, it is necessary to ensure dryness and dampness, to preserve roots and leaves, to promote grain filling and fullness, and to increase 1000-grain weight; to strengthen water and fertilizer management in sugarcane field, peel off dead leaves in time, ensure ventilation and light transmission in sugarcane fields, and improve photosynthesis effect.
Jiangnan, South China and other places should pay close attention to the post-harvesting of the late rice, the land preparation, the foot fertilizer, grab (made, scattered), sowing rapeseed (live) or transplanting rape (transplanting varieties), vegetables, green manure, potatoes, etc. Make full use of autumn and winter spring climate and land resources to ensure increased income;
4. According to the forecast, due to the influence of the cold air in the south, there will be 7-8 grades and 9 winds of northeast winds in the Taiwan Strait, Taiwan's east and south seas, and the South China Sea. Ships sailing and operating in the above-mentioned sea areas should be prepared to prevent casualties and property losses;
5. It is predicted that the cold weather will affect the northern part of Xinjiang in the middle of the week. The temperature will drop by 6-8 degrees Celsius, with 5-7 grades and 8 grades in the Yamaguchi area. Facility agriculture, animal husbandry, transportation, etc. should be well prepared for wind, snow, and cooling;
6. The autumn season is the season of fog in China. During the week, some areas such as Jiangnan, Jianghan, Jianghuai, and the southwestern part of the country should still be wary of foggy weather with visibility within 1000 meters. Road transport, rivers and lakes, and waterfront boats should be guarded against accidents and casualties. Property loss;
7. From the climatic law, after the fall, with the decrease of precipitation, the air humidity will decrease, the wind will increase, and the water content of the ground, such as dead branches and fallen leaves in forests and pastures will decrease, causing forest and grassland fire risks. The weather level is high. It is predicted that most of the eastern part of China will have fine weather, less rain (snow) and more winds in some areas. Therefore, the fire source management in forest areas and pastures should be strengthened to prevent fires in forests and grasslands.
This week's weather conditions
This week (November 1-7, 2010), there are two cold air impacts on China, the route is eastward and northerly, the northeastern part of China and the northeast are windy, and the temperature fluctuations are large; most of the eastern part of the country is sunny and sunny. The regional forest fire risk meteorological grade is high; there are many rainy (snow) weather in the eastern part of the Qinghai-Tibet Plateau to the eastern part of the southwestern region, and some areas such as Jiangnan will have foggy weather.
