Abstract: In order to know the soil nutrient status of the major orchards in Shandong Province, 248 representative orchards were selected to collect soil samples from 2018 to 2019, and soil pH, organic matter, large elements, medium elements and trace elements were quantitatively analyzed. The results showed that the pH of orchard soil in Shandong Province varied from 4.08 to 8.89, with an average of 6.29, and the whole orchard soil was acidic. The content of organic matter was extremely poor, 58.34% of the orchard was generally less than 10 g/kg. 47.92% of orchard soil was deficient in nitrogen, and the content of available phosphorus and available potassium in all orchards was abundant. The contents of medium elements calcium, magnesium and trace elements iron, manganese and zinc were in a state of coexistence of abundantce and deficiency. The content of available copper was rich, while the average content of available boron was only 0.48 mg/kg, and 55.89% of the orchard soil was seriously deficient. The main limiting factors of orchard soil in Shandong Province were soil partial acidification, lack of organic matter and insufficient content of available zinc and boron. Therefore, quicklime, biochar and other substances could be applied in production, and organic fertilizer instead of chemical fertilizer, straw returning and humic acid fertilizer application should be emphasized to improve soil pH and organic matter, and the method of foliar spraying iron, manganese, zinc and boron fertilizer could be applied to ensure the demand of fruit trees for trace elements.
