Abstract:

The paper aims to provide references for irrigation management and soil moisture prediction in cherry orchards. Based on the measured soil moisture, soil temperature and meteorological data, we analyzed the soil moisture and temperature characteristics, interrelationships and the statistical relationships with meteorological factors. The results showed that: the soil moisture in each layer of cherry orchard had different variation characteristics and had wave-mode supply and consumption under the combined action of precipitation and evapotranspiration; the change of soil temperature during the year was roughly an inverted "V" type; with the increase of soil depth, the stability of soil moisture and temperature increased; the change trend of soil moisture and soil temperature was synchronous, which was basically characterized by the simultaneous phenomenon of moisture and temperature. At different time scales, the main meteorological factors affected soil moisture during the dry and rainy season were different; with the increase of time scale, the response of soil temperature was more significant to air temperature. In conclusion, there is a cumulative effect in the response of soil moisture and temperature to meteorological factors, and the study could provide references for selecting forecast factors for soil moisture.
