Growth Parameters of Intensive Apple Orchard Using Water-saving Technology

摘要

MM106, under drip irrigation in the Chelopechene experimental field of the Institute of soil science, agrotechnologies and plant protection in town of Sofia in 2018. The experiment was designed by the long plot method with four replications. Drip irrigation with mulch and without mulch were considered as the variants of experiment. During the growing season, the apple trees were irrigated with an optimal irrigation rate. At the end of the vegetation the biometric parameters of the experimental trees:height, stem diameter, crown diameter and length of the twigs were measured.The area of cross-section of the stems, the crown volume and the average length of the twig wece estimated. Mulch and non-mulch the variants were compared. In case of drip irrigation with mulching, the apple trees showed stronger growth in the followingparameters: cross-sectional areaof the stems and crown volume. Drip irrigated apple trees without mulching had biggest average height.
