摘要： 为指导花生施肥，建立花生施肥指标体系，2008—2013年在广东省多个市县开展花生“3414”田间肥效试验研究花生施肥效应。对田间肥效试验结果进行统计分析后建立广东省花生土壤碱解氮丰缺指标数学模型：y=29.906lnx-54.015(r=0.766**，n=60)；土壤碱解氮含量与推荐施氮量数学模型：y=-85.184lnx 494.04 (r=0.725**，n=46)。根据建立的数学模型，确定土壤碱解氮丰缺范围分为：<60 mg/kg、60~80 mg/kg、80~110 mg/kg、110~150 mg/kg、>150 mg/kg 5个等级，对应的每公顷推荐施氮量为142.5 kg、120.0~142.5 kg、90.0~120.0 kg、67.5~90.0 kg和67.5 kg。

Abstract: 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 nitrogen abundance of Guangdong peanut were established. The results indicated that, the regression equation index for soil available nitrogen content was y=29.906lnx-54.015 (the correlation coefficients was 0.766); the regression equation of the recommended nitrogen content was y=-85.184lnx 494.04 (the correlation coefficients was 0.725). According to the mathematical model, the sufficiency and deficiency range of the soil effective nitrogen were divided into 5 levels: ＜60 mg/kg, 60-80 mg/kg, 80-110 mg/kg,110-150 mg/kg and ＞150 mg/kg, and the proposed index of supplying nitrogen per hectare were 142.5 kg,120.0-142.5 kg, 90.0-120.0 kg, 67.5-90.0 kg and 67.5 kg, respectively.
