滴灌条件下核桃树茎流变化规律研究
Stem Sap Flow Rate Change Rule of Walnut under Drip Irrigation
摘要
Abstract
Through field experiment,using thermal diffusion probe method to study the drip conditions for stem sap flow rate change rule and the relationship between and meteorological factor,the result shows that the stem sap flow rate in the sunny weather under the condition of daily variation in the single-peak curve changes,first increases,then decreases,cloudy conditions for stem sap flow rate for peak performance curves changing trend;Walnut trees s stem sap flow rate and solar radiation,atmospheric temperature and wind speed are positively related,and atmospheric relative humidity is inversely related,path analysis results show that the walnut trees stem sap flow rate is the greatest impact atmospheric temperature,followed by wind speed,air relative humidity,solar radiation,establishes the walnut trees stem sap flow rate regression equation between meteorological factors.关键词
