Abstract: The paper aims to stabilize and improve apple yield. The authors analyzed 500 agricultural soil zones in Baishui, Weinan, Shaanxi in 2013, and made a comparative study on pH value, total nitrogen, organic matter, alkali- hydrolyzable nitrogen, rapidly available potassium, available phosphorus, available iron, available manganese, available copper and available zinc. On the basis of the statistical data from Microsoft Excel 2010, the paper drew a conclusion that: the soil zones of Baishui where apple trees were planted had neutral to alkali pH, abundant total nitrogen and organic matter, rich rapidly available potassium, normal available phosphorus and zinc, profuse available copper, and a little available iron, alkali- hydrolyzable nitrogen and available manganese.
