摘　　要：为指导花生施肥,建立广东花生施肥指标体系,2008—2012年广东省多个市县开展的花生＂3414＂田间肥效试验。对田间肥效试验结果进行统计分析,建立了广东省花生种植土壤有效磷丰缺指标的数学模型：y=9.3071lnx＋57.724（r=0.718＊＊）;土壤有效磷含量与推荐施磷量的数学模型：y=-1.047x＋95.606（r=-0.739＊＊）。根据数学模型确定土壤有效磷丰缺范围分为〈10 mg/kg、10-20 mg/kg、20-35 mg/kg、35-55 mg/kg、〉55 mg/kg 5个等级,对应的每公顷推荐施磷（P2O5）量为82.5 kg、75.0-82.5 kg、60.0-75.0kg、37.5-60 kg和37.5 kg。This paper studied the effects of different fertilizer models on simulation for the 3414 fertilizer experiments, which were conducted from 2008 to 2012 in 30 cities in Guangdong Province. By analyzing the data, the index system of soil available phosphorus abundance of Guangdong peanut were established. The results indicated that, the regression equation index for soil available phosphorus content was y=9.30711nx＋ 57.724 （the correlation coefficients was 0.718）; the regression equation of the recommended phosphorus content is y=-1.047x＋ 95.606 （the correlation coefficients was -0.739）, According to the mathematical model, the sufficiency and deficiency range of the soil effective phosphorus were divided into 5 levels： 〈10 mg/ kg, 10-20 mg/kg, 20-35 mg/kg, 35-55 mg/kg, and 〉55 mg/kg, and the proposed index of supplying phosphorus were 82.5 kg/hm^2, 75.0-82.5 kg/hm^2, 60,0- 75,0 kg/hm^2, 37.5-60.0 kg/hm^2 and 37.5 kghm^2, respectively.
