| 摘 要： | 为加快临薯2号紫薯新品种的种植推广，达到高产、高效的目的，采用“3414”肥料试验，研究不同施肥处理对临薯2号产量的影响，并运用“测土配方施肥数据管理系统”中的“3414数据分析”系统工具分析得出最佳施肥量及最高产量。结果表明：不同用量的氮、磷、钾肥对产量影响明显，其中氮、钾肥影响较大，磷肥次之。通过数据分析得到施肥模型：每667 m2最佳施肥量为N 14.15 kg、P2O5 6 kg、K2O 24.13 kg，可得到最佳紫薯产量2 470.91 kg。

| Abstract: | Abstract: In order to accelerate the planting and promotion of new cutivar of purple sweet potato
''Linshu No.2'' and achieve purpose of high yield and high efficiency, the ''3414'' fertilizer experiment
was adopted to study the effects of different fertilization treatments on yield of purple sweet potato
''Linshu No.2'', and the system tool of ''3414 data analysis'' in the ''Soil testing formula fertilization data
management system'' was used to analyze the optimal amount of fertilizer and maximum yield. The
results showed that different amounts of N, P2O5 and K2O had obvious effects on yield, among which N
and K2O had the greatest effect, followed by P2O5. According to the data analysis, the optimal fertilizer
application mode was N of 14.15 kg per 667 m2
, P2O5 of 6 kg per 667 m2
, K2O of 24.13 kg per 667 m2
,
and the optimal yield of purple sweet potato was 2 470.91 kg per 667 m2
