Abstract：Intelligent water and fertilizer integration has the characteristics of high water and fertilizer utilization efficiency and a significant reduction in labor costs.Two methods were used to comprehensively evaluate and analyze the water use and fertilization:intelligent drip irrigation and fertilization,and conventional furrow irrigation and fertilization.This study aims to provide a reference for the popularization and application of intelligent water and fertilizer integration.The results showed that,through the study of soil moisture migration in an apple orchard,using a 2 L/h dripper with continuous drip irrigation for 8 hours can form a wet zone with a width of 50-120 cm in the depth range of 0-40 cm.According to the different growth stages of apple trees,the demand for nutrient elements varires,and the optical ratio of different nutrient elements was determined.The amount of nutrient elements applied to the single fruit-bearing tree is N-P2O5-K2O=90.5g-61.5g-1 12.5g,while for young trees,it is N-P2O5-K2O=56g-37.3g-56g.The amount of fertilizer applied per plant at each growth and development stage of the apple tree is multiplied by the number of plants in each irrigation area to obtain the total amount of fertilizer applied in each area.Based on the characteristics of the fertilizer,it is applied once every 10 days,and the intelligent drip irrigation fertilization system for the apple orchard is formulated.Compared with conventional irrigation(furrow irrigation),the intelligent drip irrigation water and fertilizer integration system achieves a water-saving rate of 84.73％,a labor-saving rate of 95.7％,and a cost-saving efficiency of 320 yuan per 667 m2.
