Abstract: As a newly-developing fruit tree, blueberry has high nutrition and medicinal value, and is highly favored by consumers. However, its growth and development have strict requirement on soil environment, which seriously affects the sustainable development of blueberry industry. In order to accelerate the high yield and good quality cultivation of blueberry, soil improvement tests were carried out by applying blueberry special fertilizer, phosphoric acid and plant ash based on the determination of blueberry cultivation soil properties. The results showed that the content of N and K of the improved soil increased to 200.5 to 1145.5 mg/kg and 10.45 to 63.5 mg/kg respectively than before, but the content of P (120.2~626.3 mg/kg) had little difference, and the organic matter content had no significant difference. The t test showed that the pH values were significantly different and pH 4.15 to 4.8 was the most suitable range for blueberry cultivation. In a word, the improved soil was suitable for regional planting of blueberry, and this study could provide certain reference for its large-scale promotion.
