This week's main agricultural activities
Most of China's areas are the drying and storage stages of autumn crops. Partial rice in the southwestern part of the southwest, 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, harvested in the south and south of China, and cotton in parts of the northwest, north China, Huanghuai, Jianghuai, Jianghan, Jiangnan and other areas continue to be harvested in the central and southern parts of North China, Huanghuai and Northwest China. Local areas such as cabbage harvesting and apple picking, citrus, banana and other fruit picking in parts of the south; rapeseed sowing or transplanting in parts of the southwestern region, Jiangnan and other places, winter wheat sowing in the eastern part of the southwest. Water-fertilizer management and pest control of winter wheat, rapeseed and other autumn-sown crops, open field vegetables, facility agriculture and double-season late rice, sugar cane and fruits in South China; 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 the precipitation in the eastern and southern parts of the Northeast will be more than normal in the same period of the previous year. There will be snow or rain to snow (sleet) in the early and middle weeks, and there will be large blizzards in the southern and eastern parts of the country. After precipitation, it is accompanied by 4-8 degrees Celsius, local temperature drop of 10-12 degrees Celsius, and northerly wind of 4-5 grade and gust 6th grade. Therefore, the greenhouses should be reinforced and protected from wind, snow and cold in advance. After the snow, the snow in the shed area should be cleaned in time to avoid losses caused by collapse and freezing caused by strong winds and snow. The food that is still piled on the field or in the ground should be covered to avoid the loss of mildew caused by rain (snow). After the rain (snow), the temperature is low, and it is necessary to prevent the road ice (snow) from adversely affecting road traffic;
2. It is predicted that there will still be more rainy (snow) weather in the eastern part of the southwestern region, usually rain (snow) or moderate rain and partial heavy rain. Rainfall should be used to collect (digging) mature rice and sweet potatoes. In areas where soil is too wet in Sichuan and Yunnan, it is necessary to clear the ditch and spread the ditch in time to ensure the smooth transplanting of rapeseed and the timely timing of winter wheat and silk peas. Sowing, and do a good job of intercepting surface runoff after rainfall, increasing the water storage capacity of mountain ponds, reservoirs, leeches, winter paddy fields, etc., and storing water resources for winter production and living in winter and spring;
3. The soil moisture in the wheat field in the northern winter wheat area with less rainfall in the past month or more has decreased. Some areas in Huanghuai and other places have been dry, which is unfavorable for winter wheat tillering and cultivating winter seedlings. It is predicted that the cold air activity in the week is more frequent and windy. Although some precipitation areas in North China and Huanghuai in the middle and late Zhou Dynasty have a precipitation process, the precipitation is small and unevenly distributed, so it should still be based on winter wheat moisture, seedlings, etc. Strengthen the management of the field, timely watering the plots with serious defects, timely suppressing, arranging and protecting the mites, promoting wheat tillering and rooting, and timely controlling pests and diseases, and cultivating strong seedlings before winter.
Continue to pay close attention to the late field management of unclosed Chinese cabbage, radish and other open vegetables in the region, to ensure that the harvest before the frost, to avoid losses caused by low temperature freezing. Facility agriculture should also do wind-proof reinforcement, heat preservation and anti-freeze work to ensure the robust growth of plants;
4. It is predicted that in the middle and lower reaches of the Yangtze River and the southern part of China, except for the many showers on the southern coast, the weather in most areas is fine and the temperature changes relatively smoothly. We should pay close attention to the harvesting of mature late rice, harvesting of one season rice, autumn corn, soybeans, peanuts, sweet potatoes, etc. in South China, picking cotton with cracked bells and citrus, bananas, etc., to ensure income increase.
In the south of China, the paddy field in the late maturity stage should be dry and wet, 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, and ensure the ventilation and light transmission of sugarcane fields. Photosynthesis.
Strengthen water and fertilizer management and pest control of rapeseed, vegetables, green manure, and potatoes that have been sown (transplanted). The missing plots should be watered in time to ensure the normal growth of the seedlings. Continue to pay close attention to the rice and other harvests after harvesting, planting the base fertilizer, grab (made, scattered), transplanting rapeseed and sowing vegetables, green manure, potatoes, etc., in order to make full use of autumn and winter spring climate and land resources to achieve income increase;
5. It is predicted that due to the influence of cold air, there will be windy weather in the eastern and southern sea areas during the week. Generally, the winds are 5-7 and the gusts are 8-9. Ships sailing and operating in the above-mentioned sea areas should be prepared to prevent casualties and property losses;
6. Autumn and winter seasons are the seasons of fog in China. In the week, parts of Jiangnan, Jianghan, Jianghuai, and the southwestern part of the country should still be alert to possible foggy weather. Road transport, rivers, lakes and reservoirs should be well guarded to avoid casualties and property losses.
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 in the week will have fine weather, less rain (snow) and more wind. Therefore, it is necessary to strengthen the fire source management of forest areas (especially the large and small Xing'an Mountains and Nanling Mountains) and grassland to prevent fires in forests and grasslands; Co.,
8. It is predicted that the cold air activities affecting China will be frequent during the week. The northern regions are windy and the temperature changes greatly. The average temperature in the local areas of North China and Northeast China is about 2 degrees Celsius lower than normal. Farmers and herdsmen friends should add clothing according to weather changes, prevent cold and keep warm, prevent colds and other diseases; farmers and herdsmen who use coal for heating should pay attention to indoor ventilation and prevent carbon monoxide poisoning.
This week's weather conditions
This week (November 8-14, 2010), the cold air activities affecting China are frequent, the temperature fluctuations in the northern regions vary greatly, and the temperature changes in the southern regions are relatively stable; the precipitation in most parts of the country is less, but the southwest is in the east. In the rainy weather, there are many showers in the south China coast, and there are more snowfall days in the northeastern region; there are many windy weather in the eastern and southern sea areas.
