Abstract: In order to study the effect of magnetized water irrigation on the cultivation of three fruit trees, apple, grape, and plum, the scientific research base of academy of Forestry in Yili River Valley, a field experiment was carried out in the experimental demonstration base of Chabuchaer County, Yili Academy of Forestry from April to October 2023. The magnetized water irrigation and conventional water source were set as the control (CK). The desalination rate of rhizosphere soil, chlorophyll content of fruit trees, fruit quality, and soil nutrients were measured and analyzed. The results showed that compared with ordinary irrigation, the salt content of rhizosphere soil of apple, grape, and plum decreased by 18.2%, 16.1%, and 25.0%, respectively, and the soil available nitrogen, available potassium, available phosphorus, and organic matter increased by 0.9%-2.3%, 0.7%-3.1%, 6.3%-8.9%, and 4.8%-18.0%, respectively. The soluble solids and hardness of apple fruit increased by 1.4%-24.8% and 4.0%-15.0%, respectively. The soluble solids, chlorophyll, and leaf nitrogen of grape fruit increased by 4%-12.6%, 15.1%-67.5%, and 22.2%-60.4%, respectively. The soluble solids, fruit longitudinal diameter, and fruit transverse diameter of plum fruit were increased by 15.1%, 6.4% and 4.9%, respectively.
