Since the beginning of spring, the temperature in most parts of the north is high; the precipitation is close to normal or slightly less, and the precipitation is timely, and the hydrothermal conditions are generally conducive to the germination and greening of the pasture. At present, pastures in most parts of the north are growing better, and the returning period is significantly earlier than the same period last year.

According to the forecast of the Central Meteorological Observatory, the temperature in most parts of the country will be close to normal or slightly higher in the next 10 days; the rainfall in northern Xinjiang, eastern Inner Mongolia, southern North China, and northeast China will be 5-20 mm, and the northeastern part of the Northeast will reach 25-40. In millimeters, the rainfall in the south of Jiangnan, South China and Southwest China is 30-60 mm. The high temperature is conducive to the growth of pasture, but the rainy and windy weather is easy to develop drought. It is suggested that the grassland area should delay the grazing time according to the growth of pasture and promote the normal growth of pasture. In addition, the grassland area will also strengthen the pest control and fire prevention work.

First, since the spring, the temperature in most parts of the north is high, and the forage grass returns to normal early and grows better.

Since March 2011, the temperature in most grassland areas of the country has been slightly higher. The temperature in the central part of Xinjiang, the western and southern Inner Mongolia, the central and northern parts of Ningxia, and the western Sichuan Plateau is slightly lower. The caloric conditions are beneficial to the growth of pasture. Most of the northern parts of the country have experienced near-normal or less than 5-10 mm of precipitation since March. The precipitation in the northeastern and southern parts of Inner Mongolia, central and northern North China, northern Xinjiang, Qinghai and Tibet, and the western Sichuan Plateau are slightly shorter than normal. More than one; the precipitation in most parts of the South is less. The western part of Inner Mongolia and Hulunbeier City, the northeastern part of Northwest China, North China, Huanghuai, and the late March, the drought situation showed a development trend, but the precipitation in the first half of April and the end of May last year eased the drought in time, plus the northern part of February The precipitation in the area is generally normal, and the forage is more adequate before returning to green. This year, the hydrothermal conditions in the northern pastures were generally better, which was conducive to the growth of pastures. The grassland in most areas was significantly earlier than last year. Most of the grassland in Inner Mongolia was 3-20 days earlier than last year.

The results of quantitative evaluation of grassland ecological meteorological model show that most of Xinjiang and Inner Mongolia, most of Northeast China, most of Qinghai, and central and western Tibet have better light and warm water conditions, which is conducive to the growth of pasture, and southwestern Xinjiang, western Inner Mongolia and Hulunbuir. In the west, central Gansu, central and northern Shanxi, northwestern Shaanxi, eastern Tibet, southwestern and southern parts of the southwestern region, and most of the south, the light and temperature waters are poorly matched, which is unfavorable for grasses to return to green and grow.

The results of satellite remote sensing monitoring also showed that the pastures in Xinjiang, Inner Mongolia, Northeast China and most of the Qinghai-Tibet Plateau have returned to green in April this year. Compared with the same period of last year, most of the northern regions have a relatively early returning trend and a preference for growth.

Second, in the next 10 days, most of the northern grassland areas will have less temperature and high rainfall, and the drought may develop, paying attention to reducing the impact.

At present, the pastures in the northeastern part of Inner Mongolia and the western part of the Qinghai-Tibet Plateau have not yet returned to green, and the rest of the grasslands in the majority of the grasslands have returned to green. According to the forecast of the Central Meteorological Observatory, in the next 10 days (May 13-22), most of the temperature in the northwestern region is higher than normal. The average temperature in the eastern part of Inner Mongolia and the northeastern region is 1 °C lower than normal. The rest of the country The temperature in the area is close to normal. Rainfall in northern Xinjiang, eastern Inner Mongolia, southern North China, and northeastern China is generally 5-20 mm, and some areas in the northeastern part of Northeast China are 25-40 mm. In the south of the Yangtze River, South China, and Southwest China, rainfall is 30-60 mm, and some areas are 100. -180 mm; rainfall in most of the above areas is close to normal or more than 2-4%. On the 16th to the 19th, there will be cold air affecting the northern region from west to east. Wind and sand weather will appear in some areas of eastern and southern Xinjiang, Hexi in Gansu, central and western Inner Mongolia, Ningxia, and northwest Shaanxi.

In the next 10 days, the northern pasture will return to the end, but the windy weather will easily cause the grassland to lose its rapidity. The drought in some parts of Inner Mongolia, northern North China, central Gansu and western Qinghai Plateau may develop. Suggestion: According to the situation of grassland returning to the past, the northern grassland area should appropriately delay the grazing time and promote the normal growth of the pasture after returning to green. At the same time, all localities should pay attention to the prevention of fire and do a good job in the prevention and control of pests.
