Microsprinkling effect on the microclimate in vine nursery
Emil Tsvetanov, Kouman Koumanov, Alexander Matev and Neli Prodanova-Marinova
Abstract: Subject of investigation was the evaporative-cooling effect of microsprinkler irrigation on improving vine production in the nursery. According to the obtained results, microsprinkling reduced the temperature of the aboveground air by 2.1-4.8°C and increased the air relative humidity by 4.4–15.8% on the average. The microsprinkling impact on the grafted cuttings was manifested by average decrease of 1.8°C and 4.2°C in the wax and the leaf temperature respectively. Microsprinkling did not affect the soil-surface temperature, which was dependent on soil moisture – a much more conservative parameter.
