Abstract

Abstract: The effects of compound fertilizer on citrus orchards soil fertilizer and fruit quality were examined. Five different experimental treatments were used as increasing organic fertilizer and reducing chemical fertilizer. The results showed that the soil organic matter content increased with the increasing organic fertilizer usage, treatment Ⅳ（Organic fertilizer,N,P₂O₅ and K₂O were 12.50,0.10,0.10 and 0.10 kg/plant, respectively）significant increased 13.1% than control treatment; The contents of total nitrogen in soil showed increasing trend, which were 0.91 g/kg. The contents of alkali-hydrolyzable nitrogen, available phosphorus and available potassium in soil showed increasing trend, which were 90.98,18.10 and 258.73 mg/kg, respectively. The content of soluble solids and titrable acid in citrus fruit increased with increasing organic fertilizer and decreasing chemical fertilizer.

Key words: citrus, compound fertilizer, soil nutrient, fruit quality
