摘　　要：为提高宁夏六盘山区黄芩生产质量,以两年生黄芩为研究对象,采用“3414”完全试验方案,即氮、磷、钾3个因素,4个水平,14个处理的大田试验,探讨氮磷钾不同施肥量对黄芩产量的影响,采用频率分析法计算黄芩施肥的推荐施肥量。结果表明:氮、磷、钾单因素对黄芩产量的影响顺序为钾肥>氮肥>磷肥。经频率分析,黄芩施肥优化施肥量产量为7141.66 kg·hm^(-2),氮肥(N)推荐施肥量为96.90~141.99 kg·hm^(-2),磷肥(P2O5)推荐施肥量为72.73~101.72 kg·hm^(-2),钾肥(K2O)推荐施肥量为104.48~151.07 kg·hm^(-2),施肥配比为1∶0.72~0.75∶1.06~1.08。该推荐施肥量比较符合生产实际,肥料配比较为合理,符合黄芩对养分的需求规律。In order to improve the production quality of Scutellaria baicalensis Georgi in Liupan Mountain Area of Ningxia,taking two-year-old Scutellaria baicalensis Georgi as the research object,the"3414"complete test scheme,namely the field test of three factors,four levels and 14 treatments of nitrogen,phosphorus and potassium,was used to explore the effects of different fertilization rates of nitrogen,phosphorus and potassium on the yield of Scutellaria baicalensis Georgi,and the frequency analysis method was used to calculate the recommended fertilization rate of fertilization.The results showed that the order of the effects of nitrogen,phosphorus and potassium on the yield of Scutellaria baicalensis Georgi was potassium fertilizer>nitrogen fertilizer>phosphorus fertilizer.Through frequency analysis,the yield of Scutellaria baicalensis Georgi under optimized fertilization was 7141.66 kg·hm^(-2),the recommended fertilization of nitrogen fertilizer was 96.90-141.99 kg·hm^(-2),the recommended fertilization of phosphorus fertilizer was 72.73-101.72 kg·hm^(-2),the recommended fertilization of potassium fertilizer was 104.48-151.07 kg·hm^(-2),and the fertilization ratio was 1∶0.72-0.75∶1.06-1.08.The recommended amount of fertilizer is more in line with the actual production,and the fertilizer allocation is more reasonable,which is in line with the nutrient demand law of Scutellaria baicalensis.
