1应用热扩散法测定香蕉树蒸腾速率显示文摘香蕉树植株高大,一般采用间接方法确定耗水量,但所得结果受土壤、大气和农艺措施等因素的影响较大.本文于2005年11月15日—12月5日在温室内采用热扩散法(即Granier法)测定香蕉树的茎液流,并与用数字天平(称重法)测定的香蕉树蒸腾速率进行对比试验.结果表明,Granier法测定的日茎液流量与称重法测定的日蒸腾量相差4%.Granier法测定的茎液流速率一般滞后于称重法确定的蒸腾速率1h左右.当日蒸腾量小于0.05L.m-2(活性叶面积)时,Granier方法不能测定茎液流量.Granier传感器一般在安装2~3d后即可正常工作,同时在多株植株上安装Granier传感器取其平均流速值计算蒸腾量可以明显减小测量误差.刘海军 SHABTAI Cohen JOSEF Tanny 黄冠华 2007应用生态学报2007,18,1:18
2Quantitative estimation of climate change effects on potential evapotranspiration in Beijing during 1951-2010显示文摘Climate change is likely to affect hydrological cycle through precipitation,evapotranspiration,soil moisture etc.In the present study,an attempt has been made to study the climate change and the sensitivity of estimated evapotranspiration to each climatic variable for a semi-arid region of Beijing in North China using data set from 1951 to 2010.Penman-Monteith method was used to calculate reference crop evapotranspiration(ETo).Changes of ETo to each climatic variable was estimated using a sensitivity analysis method proposed in this study.Results show that in the past 60 years,mean temperature and vapor pressure deficit(VPD) were significantly increasing,relative humidity and sunshine hours were significantly decreasing,and wind speed greatly oscillated without a significant trend.Total precipitation was significantly decreasing in corn season(from June to September),but it was increasing in wheat season(from October to next May).The change rates of temperature,relative humidity,VPD,wind speed,annual total precipitation,sunshine hours and solar radiation were 0.42℃,1.47%,0.04 kPa,0.05 m·s–1,25.0 mm,74.0 hours and 90.7 MJ·m–2per decade,respectively.In the past 60 years,yearly ETo was increasing with a rate of 19.5 mm per decade,and total ETos in wheat and corn seasons were increasing with rates of 13.1 and 5.3 mm per decade,respectively.Sensitivity analysis showed that mean air temperature was the first key factor for ETo change in the past 60 years,causing an annual total ETo increase of 7.4%,followed by relative humidity(5.5%) and sunshine hours(–3.1%);the less sensitivity factors were wind speed(0.7%),minimum temperature(–0.3%) and maximum temperature(–0.2%).A greater reduction of total ETo(12.3%) in the past 60 years was found in wheat season,mainly because of mean temperature(8.6%) and relative humidity(5.4%),as compared to a reduction of 6.0% in ETo during corn season due to sunshine hours(–6.9%),relative humidity(4.7%) and temperature(4.5%).Increasing precipitation in the wheat season will improve crop growth,while decreasing precipitation and increasing ETo in the corn season induces a great pressure for local government and farmers to use water more efficiently by widely adopting water-saving technologies in the future.LIU Haijun LI Yan JOSEF Tanny ZHANG Ruihao HUANG Guanhua 2014Journal of Geographical Sciences2014,24,1:10
3温室内香蕉树蒸腾量预报的试验研究显示文摘在温室内研究了香蕉树蒸腾量和小气候的关系,用5种方法计算了温室内的参考作物腾发量,用20 cm蒸发皿测定温室内的水面蒸发力,并和测定的香蕉树蒸腾量进行对比.试验结果显示香蕉树蒸腾量和蒸发皿水面蒸发量的回归系数(R2)最高,为0.94,而和5种公式计算的参考作物腾发量的回归系数为0.47~0.60,以蒸发皿水面蒸发量计算温室内的作物蒸腾量要优于以参考作物腾发量计算作物蒸腾量的方法.温室内香蕉树的蒸腾量和20 cm蒸发皿蒸发量线性相关,可以此计算温室内作物的蒸腾量.刘海军 黄冠华 Josef Tanny Shabtai Cohen 2007农业工程学报2007,23,3:8
4用涡度相关法测定网室内香蕉树蒸散量显示文摘为了研究涡度相关法在网室内的适用性,于2005年6月在一个长、宽、高分别为352m、228m和6m的香蕉树种植网室内进行试验,测定的参数主要有网室内的潜热和感热、网室内的净辐射,土壤热通量和表层土壤热量。研究发现涡度相关法测定的能量和和小气候仪器测定的能量一致,说明涡度相关法可用来准确测定网室内作物的蒸散量。在试验期间(6月7日-20日),涡度相关法测定的网室内香蕉树的蒸散量在4.83~6.50mm/d之间,考虑到当地每年4~10月之间气象要素变化较小,则该文测定的蒸散量可用来指导当地网室内香蕉树的灌溉。刘海军 黄冠华 Josef Tanny Shabtain Cohen 2008农业工程学报2008,24,9:5
5网室内小气候要素的变化规律显示文摘在以色列的大型香蕉种植网室内(352m×228m),观测研究网室内小气候的变化过程、垂直分布规律以及与网室外小气候要素的关系。结果显示,网室的光透射率随着使用时间的增加而减小;网室内外小气候要素间呈线性相关关系,与网室外相比,网室内的相对湿度高、饱和水汽压差小、风速显著降低,但是温度差异较小;网室内外小气候要素(相对湿度、温度和饱和水汽压差)的差异随着风速的增加而减小;网室内冠层附近水汽密度高于近地面处的水汽密度,且出现逆温分布。刘海军 黄冠华 Josef Tanny Shabtai Cohen 2009中国农业气象2009,30,1:5
6网室栽培香蕉耗水特征及合理灌溉水量确定显示文摘主要研究网室和不同灌溉水量下香蕉的耗水特征,确定香蕉的作物系数。处理包括大田充分灌溉处理(100%),网室充分灌溉处理(100%)和亏水处理(5S%),香蕉的耗水量(ET)用热消散茎液流法测定。试验结果显示,在3种处理间香蕉叶面积差异不显著(P〉0.05),网室内香蕉的耗水量比大田降低了44%~55%;网室内2种灌溉水量条件下香蕉蒸散量差异不显著(P〉0.05),说明55%处理灌溉水量已经能够满足香蕉的生长,这个结果也和网室内蒸散量降低值一致。建议当地进行网室内香蕉栽培时,灌溉水量选取大田的一半即可。刘海军 黄冠华 J Tanny S Cohen 2008灌溉排水学报2008,27,5:4
