This week's main agricultural activities
Harvesting of autumn corn, autumn soybeans and sweet potatoes in parts of southern China, picking of citrus and banana fruits in parts of southern China; transplanting of rapeseed in parts of eastern and southern parts of southwestern China, sowing of vegetables, potatoes and fresh corn in southern China . Water-fertilizer management and pest control of winter wheat, rapeseed and other autumn-sown crops, open field vegetables, facility agriculture, and sugarcane and fruits in South China have been emerged or transplanted; farmland water conservancy infrastructure construction and local area disaster relief and disaster relief.
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 two obvious cold air affecting China during the week. Among them, due to the influence of cold air in the early period of mid-week, the temperature in most of the northwest, north China, northeast, Huanghuai and other places dropped by 4-8 degrees Celsius, including the north-central part of northern Xinjiang and the north-central part of north-eastern China, and the south-central and eastern parts of northeastern China. In some areas, the temperature range is 10-14 degrees Celsius, and the local area is above 16 degrees Celsius. The above-mentioned areas have 4-6 grades, Xinjiang Shankou and Wind Zones have 8-9 winds, and parts of Gansu West and Inner Mongolia Midwest have sand. Dust weather; small to medium snow (rain) or sleet in northern Xinjiang, central and eastern Inner Mongolia, and most of the northeastern part of the country, including snow in the northern part of Xinjiang, northeastern Inner Mongolia, central and eastern Heilongjiang, central Jilin, etc. Blizzard. In the latter part of the week, it was affected by another strong cold air from west to east. The temperature in most areas was 6-10 degrees Celsius, and the temperature in some parts of the north was 12-16 degrees Celsius. The north part of the Yangtze River will have a northerly wind of 5-6 levels. The wind power in the mountainous and windy areas of Xinjiang can reach 8-9, and there will be sand dust in parts of the southern Xinjiang basin and western Inner Mongolia. There are 4-5 winds in the south of the Yangtze River; small to medium snow in the north of Xinjiang, some areas There is a big blizzard. Therefore, facilities such as greenhouses, livestock and poultry houses should continue to do wind and snow reinforcement, cold protection, heat preservation, etc. After snow, clean the snow on the shed to avoid collapse, damage and freezing damage caused by snow or strong wind. After the snow, the temperature is low. In some areas, it is necessary to prevent the adverse effects of traffic caused by snow and frozen roads. The pastoral area should continue to do the reserve, transportation and grazing of forage materials, wind and snow, dust and cooling work for the transition; Co.,
2. It is predicted that some areas in the eastern part of the southwestern region will still have more rainy weather during the week, generally with light rain, and some areas in Sichuan and Guizhou have moderate rain. Some soil over-wet plots should be done in time to clear the ditch and ploughing, to ensure the robust growth of rapeseed, wheat, vegetables, etc., and continue to do a good job of intercepting surface runoff after rainfall, increasing mountain ponds, reservoirs, water storage cellar, the winter paddy fields;
3. In the past more than a month, there was no obvious precipitation weather in most of the northern winter wheat areas. The temperature was high and windy. The soil moisture in the wheat field showed a downward trend. The growth of wheat seedlings in some areas has been affected to varying degrees. It is predicted that there will be two obvious cold air effects in the week, the wind is large, and there is no obvious precipitation process in most areas, and the meteorological drought is still developing. Therefore, we should continue to strengthen field management according to winter wheat lyrics, seedlings, etc., suppress and plan, maintain warmth, promote wheat rooting and tillering, timely control pests and diseases, and cultivate strong seedlings before winter. According to the temperature change and water source, when the average temperature of the day drops below 5 degrees Celsius (when the night is frozen), winter irrigation (especially the land with serious grievances) is carried out in time, and the insulation is increased to facilitate safe wintering and early spring growth. . Facility agriculture should do wind-proof reinforcement, heat preservation and anti-freeze work to ensure the healthy growth of vegetables and flowers to meet market demand;
4. Last week, rainfall occurred in Jiangnan and western China. It is predicted that some areas in the south of the Yangtze River and southwestern China will still have intermittent light rain, partial moderate rain or showery weather, which is beneficial to the transplanting survival and seedling growth of rapeseed and vegetables. It is necessary to continue to strengthen the management of water and fertilizer such as rapeseed, vegetables, potatoes, green manure and fresh corn that have been sown (transplanted), cultivating and cultivating soil, checking seedlings, replenishing seedlings and controlling pests and diseases, and watering the plots that are still lacking should be timely watered to ensure Seedlings grow robustly. Some areas in southern China should continue to pay close attention to the post-harvest twigs and land preparations, and apply the base fertilizers. After the rain, it is a good time to smash or transplant vegetables, potatoes, fresh corn, etc., in order to make full use of the winter climate and land resources. To increase income and ensure market supply, and use autumn rainfall to harvest autumn corn, autumn soybeans, autumn peanuts, sweet potatoes, and picking ripe citrus, bananas and other fruits and drying late rice to ensure increased production and income; Co.,
5. It is predicted that due to the influence of cold air, the winds in most of the eastern and southern sea areas will increase in the middle and late Zhou Dynasty, generally 6-7, and the gusts will reach 8-9. Ships sailing and operating in the above-mentioned sea areas should be prepared to prevent casualties and property losses;
6. It is predicted that fog may occur in parts of the North China Plain, Jianghan, Jiangnan, and the eastern part of the southwestern part of the country during the week. Roads and rivers and lakes will be protected by water surface transportation;
7. From the climatic law, the autumn and winter seasons decrease with the decrease of precipitation, the air humidity decreases, the wind increases, and the moisture content of the litter and leaves in the forest and grassland decreases, resulting in the fire weather level of forests and grasslands. High. It is predicted that there will be more fine weather in the central and southern parts of North China, Huanghuai and parts of southern China during the week, with less rainfall and greater winds. Therefore, the fire source management in the forest area should be strengthened to prevent forest fires; Co.,
8. It is predicted that there will be two obvious cold air affecting China in the week. The changes in heating and cooling are large and windy, and there are snow and rain in some areas. Farmers and herdsmen's friends should add clothing according to the weather, keep warm and prevent colds and other diseases. Farmers and herdsmen who use coal for heating in the north should pay attention to indoor ventilation and prevent gas poisoning.
This week's weather conditions
This week (November 29 to December 5, 2010), there will be two obvious cold air affecting China. The temperature fluctuations in the northern region are relatively large, and the temperature changes in the southern region are relatively stable. The average weekly temperature in the eastern and northeastern regions of North China The temperature is about 1 degree Celsius, and the temperature in most other parts of China is 1-2 degrees Celsius. There will be snowfall in northern Xinjiang, northeastern Inner Mongolia and northeast China, and some areas in the southwest of the southwest are cloudy and rainy.
