井式节水灌溉下干旱区灰枣树干液流动态及其对气象因子的响应
Stem sap flow dynamic of jujube and its response to meteorological factors in the arid area under pit irrigation
摘要
Abstract
Stem sap meter (TDP) and HOBO microclimate were used to continuously monitor the stem sap flow rate and meteorological factors of jujube in full fruit period under the condition of pit irrigation in the arid area.The results showed that the total amount of sap flow in the whole growth period of jujube was 3 935 kg,and the accumulation of sap flow in summer was 2 387 kg,which accounted for 61％ of the whole growth period.The transpiration water consumption in summer was the most serious(severe).The main meteorological factors affecting the stem sap flow of each month were different,and the proportion of solar radiation accounted for more months.Higher solar radiation and value of water vapor pressure deficit don't indicate higher flow rate,the flow rate depends on the time,meteorological and jujube's physiological state.关键词
