Study on index system of soil testing and formulated fertilization for peanut

According to the "3414" full implementation design, a field fertilization experiment on peanut was carried out. The results showed that:the critical value of abundance index of alkaline hydrolysis nitrogen, available phosphorus and available potassium in the peanut soil of Putian City ranged 54-115 mg/kg, 6-22 mg/kg and 18-103 mg/kg respectively, and out of the range were rich or lack, and the recommended fertilization of N, P₂O₅ and K₂O on medium fertility field were 5.07-8.73 kg/667 m² (76.05-130.95 kg/hm²), 3.40-4.53 kg/667 m² (51.00-67.95kg/hm²) and 2.47-11.8 kg/667 m² (37.05-177.00 kg/hm²), respectively.
