【摘要】 本文依据2005年~2006年毛乌素沙地乌审旗气象观测资料,对人工草地SPAC中的大气水势日、季变化规律及其影响因子进行了分析研究。试验结果表明:人工牧草生长期间大气水势均值为-139.573Mpa,日、季变化明显,呈单峰型;大气水势变化与大气温度、相对湿度、太阳辐射、风速之间具有十分显著的相关性。更多还原

【Abstract】 The changing low of atmosphere water potential and its influential factors in artificial grass SPAC system was researched in this article according to the meteorologic data during 2005 to 2006 in Maowusu desert.The result of experiment indicate that the average of atmosphere water potential during grass,growing period is-139.57MPa,changed obviously,the curve is unimodal;between the change of atmosphere water potential and temperature、relative humidity、solar radiation、wind speed have very notable correlativity.更多还原
