| 摘 要： | 以4年生‘红富士’(中间砧为‘SH3’)为试材,利用AZ-D茎流系统监测生长期茎流数据、HOBO气象站同步监测气象因子数据,研究了其茎流变化规律及其与环境因子的关系.结果表明:生长期苹果茎流呈现出明显的日际、旬变化特征,2008、2009年旬茎流量最大值分别为50.84 kg和86.09 kg,整个生长周期中新梢二次生...

| Abstract: | 4 year ’Red Fuji’ apple trees was used to study the sap flow by AZ-D observation system,and meteorological factors data were monitored by HOBO weather station meteorology system simultaneously.The variations of sap flow and influence factors were analyzed.The results are as follows: The sap flow demonstrated daily and ten-day variations in growing season.The highest sap flows are 50.84 kg and 86.09 kg in a period of ten days in 2008 and 2009 respectively.A large part of the sap flow appeared in the second growing season of shoots and the proportion amounted to 25.41% and 34.11% respectively.There are significant positive correlations between sap flow rates with air temperature,ground temperature,the total radiation and photosynthetic active radiation. |
