The growth of grassland vegetation in China was generally good in June.

The grassland Supervision Center of the Ministry of Agriculture used the methods of satellite remote sensing and ground observation, combined with the meteorological monitoring information of the National Meteorological Center, to monitor and analyze the growth of grassland vegetation across the country in June this year. the results show that there is abundant precipitation in most grasslands in June, and the growth condition of vegetation is generally better than that in the same period in recent years and the same period last year.

I. Meteorological conditions

In June, the whole country showed a temperature pattern of hot in the south and cool in the north. Except for a few high latitude areas such as Hulunbuir, Inner Mongolia, which were affected by low temperature and low light, and the vegetation grew slowly, the heat condition was beneficial to the growth of grassland vegetation in China as a whole. The precipitation is abundant in the grassland areas of the whole country, in which the precipitation in the eastern part of Xinjiang, the middle-eastern part of Inner Mongolia and the western part of Northeast China is more than 30% more than that in normal years, and the water condition is beneficial to the growth of grassland forage.

II. Status of vegetation

Through the comparison and analysis of satellite remote sensing images, the growth status of grassland vegetation in June is generally better than that of the same period in recent years and the same period last year. Compared with the same period last year, 29% of the grassland vegetation growth condition is good, 47% of the grassland vegetation growth condition is the same, and 24% of the grassland vegetation growth condition is deviated. Compared with the same period in the past five years, 30% of the grassland vegetation growth status is preferred, 51% of the grassland vegetation growth status is flat, and 19% of the grassland vegetation growth status is deviated. The areas of vegetation growth preference are mainly distributed in the west of Northeast China, the central and eastern part of Inner Mongolia, Xinjiang, the eastern part of Qinghai-Tibet Plateau and the central and western part of Gansu. The areas of vegetation growth deviation are mainly distributed in the middle of Xizang and the southwest of Inner Mongolia.

From the perspective of the main pastoral areas, the grassland vegetation grows well in Xingan'an, Tongliao City, Xilingol League and Wulanchabu City in the central and eastern part of Inner Mongolia, but the Hulunbuir grassland in the east is affected by low temperature and little rain, and the Ordos grassland in the west is affected by drought and little rain. the growth of grassland vegetation is poor. The overall growth of grassland in Xinjiang is good, among which the coverage and height of forage grass in northern Xinjiang are higher than those in the same period last year due to abundant precipitation. The grassland of Qinghai shows a pattern of favorable growth in the south and a slight difference in the north. The eastern and western grasslands of Xizang grassland grow well, while the grasslands in the central part grow poorly under the influence of drought. The overall growth trend of Sichuan grassland is preferred, among which the forage grass in some areas of northwest Sichuan enters the flowering stage ahead of time. The growth of grassland vegetation in Gansu is mainly flat and slightly better, in which the growth of grassland vegetation in the central and eastern part of Hexi Corridor, the Loess Plateau in central Gansu and the central part of Gannan is better than that in the same period last year, while that in other areas is basically the same or slightly worse than that in the previous year.

III. Analysis and suggestions of the late situation

According to the forecast of the National Meteorological Center, for a period of time in the future, the temperature in most grasslands across the country will be slightly higher, the precipitation will be close to the same period of the year, and the meteorological conditions are generally conducive to the growth of forage grasses; however, the precipitation in western Inner Mongolia and the eastern part of Northwest China may be more than 20% less, and drought may occur in some areas. All localities should make rational arrangements for grassland and animal husbandry production and management activities according to the current forage growth situation; western Inner Mongolia and other places should do a good job in coping with grassland drought, strengthen grass-livestock balance management, and monitor and control grassland rodent and pest pests.
