【 摘 要 】

In the conditions of arid zones of irrigated agriculture, during thecultivation of horticultural and other crops, high air temperatures (over 25-30оС) and low relative humidity (less than 20-30%) are observed during thevegetation period of plants. In these circumstances, the combined irrigationmethod using drip irrigation and sprinkling allows optimizing the use of waterduring drip irrigation at air temperatures below 25-30оС and improving the microclimate through sprinkling at air temperaturesabove 25-30оС. The study aims to determine theeffect of the combined irrigation method on the microclimate, water regime ofplants, and water productivity compared to the drip irrigation system. The keyresearch method employed is a field experiment conducted on a speciallyallocated plot of land to establish differences between the two methods ofirrigation. The field experiment presupposes an exploratory study andquantifies the effect of the new technology of irrigation of apple trees toobjectively justify the implementation of this scientific development inagricultural production. The combined method of irrigation provides a decreasein air temperature by 1.5-2.1°C and increases air humidity by 10-17% in thesurface air layer, improving the water regime of plants and increasing theapple yield by 10.7-17.9% against drip irrigation, while reducing waterconsumption per production unit by 4.0-10.1%. The method of combined irrigationis thus recommended for use in the arid zone of irrigated agriculture.
