| 摘 要： | 采用经典称重法,结合HOBO自动气象站的实地观测,分析了北京地区栓皮栎盆栽幼苗的水分需求规律和水分供求关系以及气候因素对其水分需求的影响。结果表明:在遮雨棚内,不同水分梯度下栓皮栎容器苗整个生长季的需水变化呈现先上升后下降的趋势,需水量从5月逐渐上升,到7、8月份达到最高峰,9月份开始下降直至10月试验结束。2008年整个生长季各水分梯度最高需水量在7月底8月初,此时各水分梯度苗木需水总量分别为:4936.56mL.株-1.月-1(90%)、3017.21mL.株-1.月-1(70%)、2267.17mL.株-1.月-1(60%)、2010.72mL.株-1.月-1(50%)、1507.61mL.株-1.月-1(40%)。苗木耗水与空气温度、湿度、降雨量和风速有着很好的复相关性,程度大小依次为:大气温度空气湿度降雨量平均风速。

| Abstract: | The water consumption law and the water supply-demand relationship of Quercus variabilis potted seedlings under different soil moisture gradients (40 percent,50 percent,60 percent,70 percent and 90 percent) were analysed using the classical weighing method according to the data from the HOBO automatic weather station. The effects of climate factors on the water consumption of 2-year-old Q. variabilis potted seedlings were also studied. Results indicate that the water consumption of the seedlings under diffe... |
