Low temperature in summer and low rainfall in summer, the growth of northern pasture is worse than the same period last year

April 2010 to July, the northern most area of grassland rainfall, high temperatures, which from April to May low temperatures, from June to July, hot and dry, the overall weather conditions unfavorable grass growth. In particular , the precipitation in central and western Tibet from April to June and the central and western Inner Mongolia from June to July was less than 50 %. The high temperature and low rainfall accelerated the soil loss. The continuous drought caused the yellow tip, high retraction and dryness of the forage. . Most of Qinghai, southeastern Tibet, Ningxia, and central and southern Xinjiang have relatively good water and heat matching from April to July , which is conducive to grass growth. In general, in 2010 , the grassland area in the northern part of the grassland has been poorly matched by water and heat, which is not conducive to the growth of pasture; the southeastern part of Tibet, most of Qinghai, and Ningxia have better water and heat matching, which is conducive to the growth of pasture.

As of the end of July , the grassland yield in most of the northern grasslands was flat or slightly lower than the same period last year.

The calculation results of grassland ecological meteorological model show that the grass yield in most grassland areas in northern China is flat or slightly lower than that in the same period of last year. Most of Inner Mongolia, the central and western Tibet and Other pastoral areas are affected by high temperature and low rainfall, and the northern part of Xinjiang is affected by low temperature. the amount of different degrees of decline, mostly pastoral grass production than the same period last year low of 20 to 100 kg / ha, lawn lower part 100 to 400 kg / ha. The amount of land in most of Qinghai, eastern Tibet, most of Gansu, Ningxia, southern Xinjiang, etc. is close to or slightly higher than the same period last year.

It is expected that the increase of unfavorable forage production in northern weather in August should be done for livestock forage allocation and reserve work.

According to the National Climate Center, in August , the temperature in most grassland areas in the north is higher than normal and the precipitation is less. The matching of water and heat is still not conducive to the growth of pasture. The drought in most parts of Inner Mongolia and northwestern Gansu may continue or develop, affecting pasture. Yield formation. In eastern Tibet, most of Qinghai, and northern Xinjiang, there was more precipitation in August , and the normal temperature was higher, which was beneficial to increase the yield of pasture. Suggest:

First, the northern pastoral areas should strengthen the forage preparation and storage work to ensure the normal supply of livestock forage.

Second, the dry pastoral areas such as Inner Mongolia and western Tibet should strengthen the monitoring and prevention of grassland fire prevention to prevent problems before they occur.
