From February 15 to 19, according to the Tibet Autonomous Region Meteorological Bureau, the drought survey was conducted on winter wheat and some grassland in Lhasa and Shannan. Although the precipitation along the Yarlung Zangbo River in the whole winter was less, there was no effective precipitation in many places. However, the infrastructure of the water conservancy facilities in this area is relatively complete and the irrigation conditions are good. The winter irrigation measures are effective, so that the soil in the main irrigation areas of the main agricultural areas is suitable for wintering. The growth of crops has not been widely affected by the climate drought. The impact of the current drought on spring sowing is mainly due to the fact that this year's drought has reduced the amount of soil water stored in the rain-casting area. If the precipitation continues to be less in the middle and late March to the beginning of April, it will be detrimental to the spring sowing of the rain-casting area. influences. When the male grass field is still in the wintering period, the meteorological conditions with high temperature and low precipitation have no significant impact on the temporary fashion of pasture.
It is estimated that in mid-March, the temperature in most parts of Tibet is high, and the precipitation is mainly distributed in Naqu, Qamdo, Nyingchi and other areas. Lhasa, Shannan, Shigatse and other major agricultural areas along the Yajiang River valley still have no obvious rain or snow, and the recent meteorological drought may continue. Or increase.
From the 10th to the 14th, there are small to medium snow (rain) in the areas of Changdu, Nyingchi and the eastern part of the Nagqu area, and heavy snow (rain) in the local area. The whole area has 4 to 6 degrees of temperature cooling from west to east. At the end of the year, there was light rain or sleet in the Nyingchi area; the Nagqu area and the Changdu area were cloudy with cloudy days, and some places had snow showers.
In March, the precipitation in the Linzhi area, the southern marginal area, and the local area along the Yangtze River was more than normal, and other areas were normal. The monthly average temperature is slightly lower in the southern margin, and the other regions are slightly higher. How windy weather along the Yangtze River.
In April, the line along the Yangtze River was slightly normal, and other areas were normal. The average temperature is high in the whole district.
Production life advice
1. Due to the recent windy weather, it is easy to cause sand and dusty weather. It is necessary to strengthen the greenhouse and outdoor hanging facilities, and the forest area needs to be protected against forest fires.
2. There is less precipitation in the main agricultural areas along the Yajiang River valley. It is necessary to strengthen the field management of green crops and prepare for drought relief. The temperature continues to be high, creating favorable conditions for the safe wintering of pests and diseases. The possibility of pests and diseases in spring and summer will be To increase, we must conscientiously do the spring irrigation of compost before sowing and the soil repression after sowing; take measures such as seed selection, drug soaking, soil disinfection, seed coating, etc., and strengthen the field management with prevention and control as the focus.
3. The northern part of Tibet has entered the peak of the lambing season. The temperature changes greatly and the cold air is more frequent. Please pay attention to the cold and warmth of the young animals. In the windy and windy weather, the animals should be rushed to the shelter in time to prevent the livestock groups from being Blow off.
