Abstract

Abstract:

【Objective】The law of transpiration of fruit trees is embodied in the characteristics of sap flow. The objective of this paper was to study the transpiration and water consumption laws of Malus pumila Mill (‘Hanfu’) in Northeast China, so as to provide a theoretical basis for the development of suitable irrigation system.【Method】In this experiment, the sap flow rates from young fruit stage to the deciduous stage of Hanfu apple trees were continuously monitored by the thermal dissipation probes (TDP) from May to October in 2017, and the meteorological data were continuously recorded by automatic weather station in this orchard. The characteristics of sap flow in Hanfu apple trees and their relationship with environmental factors were analyzed, and then a regression model between sap flow rate and environmental factors was established.【Result】The results showed that the rates of sap flow in Hanfu apple trees were higher in the daytime than that at night. The sap flow rates of Hanfu apple trees at night were stable, the change of sap flow rate was gentle and closed to zero between 0 o’clock and the sunrise, and the high sap flow rate level was still maintained in the period from the sunset to 0 o’clock of the next day. During the growth periods of fruit trees, the start-up and fall time of sap flow was concentrated, and the time of reaching the peak value was dispersive. The proportion of nocturnal sap flow was October > September > May > June > August > July. The proportion of nocturnal sap flow in October was 33.69%, but only 4.57% in July. The correlation degree between environmental factors and sap flow of Hanfu fruit trees was as follows: solar radiation > atmospheric temperature > wind speed > water vapor pressure difference > relative humidity > 30cm soil layer temperature. The multivariate regression equation of sap flow rate and environmental factors of Hanfu fruit tree was: V=6.441+0.012Rn+1.874T–0.577Ts,_5cm+1.915Ws–9.766VPD–0.362RH, and the correlation coefficient of R ² was 0.842. The correlation coefficient between daily sap flow and 10cm soil moisture content was 0.521, which was not significantly correlated with the other layers soil moisture content. 【Conclusion】 The results showed that in the cold area of Northeast China, the transpiration of Hanfu apple trees was large from June to September, and the transpiration was affected by solar radiation, wind speed and other environmental factors. It should be noticed that in the fruit expansion period, especially in July and August, the irrigation should be carried out timely. Irrigation time should avoid the strongest solar radiation time, and be arranged before sunrise or after sunset to reduce water loss caused by evaporation.
