花生测土配方施肥指标体系研究

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

摘要: 根据“3414”完全实施方案设计花生田间施肥试验，结果表明：莆田市的花生土壤碱解氮、有效磷和速效钾的丰缺指标临界值分别为54~115 mg/kg、6~22 mg/kg和18~103 mg/kg，区间外的分别为丰富和缺乏；中等肥力水平田块每667 m²推荐施肥量为N 5.07~8.73 kg、P₂O₅ 3.40~4.53 kg、K₂O 2.47~11.8 kg。

Abstract: 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.
