| 摘 要： | 采用"3414"肥料效应试验设计方案进行田间试验,对紫云英氮、磷、钾肥效应以及肥料的交互作用进行了分析,并筛选出适宜的氮、磷、钾肥用量。结果表明:施用氮肥紫云英增产效果最好,鲜草增产量最高达21.1 t/hm2,增产率为158.6%;施用磷肥增产量为10.8 t/hm2,增产率为81.1%;而施用钾肥增产效果不显著。在本试验条件下,中磷、中钾水平最适宜氮肥肥效的发挥,中氮、中钾水平最适宜磷肥肥效的发挥,中氮、中磷水平最适宜钾肥肥效的发挥。通过肥料效应模型拟合,得到本试验条件下种植紫云英的肥料适宜用量为N 60.2 kg/hm2、P2O549.4 kg/hm2和K2O 64.2 kg/hm2。 |

| Abstract: | The effects of nitrogen,phosphorus and potassium fertilizers and their interaction on Astragalus sinicus were studied through 3414 fertilizer experiment design.The results showed that the fresh increment was 21.1 t/hm^2 with applying nitrogen fertilizer,which increased by 158.6%.The fresh increment was 10.8 t/hm^2 with applying phosphorus fertilizer treatment,which increased by 81.1%.The yield-increasing effect was not significant with applying potassium fertilizer.Through the fertilization effect model,the suitable N,P2O5 and K2O amounts were 60.2 kg/hm^2,49.4 kg/hm^2 and 64.2 kg/hm^2,respectively. |
