Comment on Growth Vigor of Natural Forage Grass in Urumqi in 2006

根据2006年和历年牧业气候条件、土壤相对湿度、牧草的生长发育及产量状况对照分析，2006年春季，乌鲁木齐南山中山带山地牧业区气象条件、牧草长势普遍较好；夏季前期（5—7月上旬）降水基本正常、气温偏高、雨热配合较好，对天然牧草的生长发育十分有利，后期降水偏少、温度偏高，土壤失墒较为严重，部分地区出现了轻-中度旱情；秋季（8、9月），降水偏少、气温偏高，黄枯期较历年平均日期提前了8—13天。乌鲁木齐南山中山带山地草甸牧业区牧草产量高于去年及历年平均值，属平偏丰，气候年景较有利于畜牧业生产。

According to 2006 and all previous years animal husbandry climatic conditions, soil Relative humidity,forage grass growth and output condition were analyzed. In spring 2006 in the southem,rnountains in Urumqi area under animal husbandry area meteorology condition , the forage grass growing trend is generally better; In earlier stage of summer （in May to beginning of July） the precipitation basic cally is normal.Tbe air temperature is high.The rain and heat show better coordination , it is extremely advantageous to the natural forage grass growth. In the later period, the precipitiation is slightly little, the air temperature is a little high, the soil moisture content is serious; the moderate drought situation occurs in the partial areas;In autumn （in August, in September}, the majority of local precipitation is little , the air temperature is high.
