| 摘 要： | 以硅钙钾肥(陕西华县荣昌钾肥厂提供)为试材，研究了该矿质肥料在生地上的应用效果。结果表明，有设置的7个处理中，以施肥1500kg/hm2增产最高，鲜、干重产量分别比对照高22.44%和40.57;施肥量750kg/hm2的产出投入率最高，其鲜药产出投入率为6.53，干药为18.81;经回归分析，得出硅钙钾肥的最佳施用量，鲜重为2086.95kg/hm2,干重为2062.2kg/hm2,最高产量分别为24.79t/hm2和6.53t/hm2。

| Abstract: | Experiment on effects of Si, Ca, K fertilizer applications on dried Radix rehmanniae was done. The result showed that among seven treatments, output of dried Radix rehmanniae was highest as the amount of Si, Ca, K fertilizer application was 1500kg per hectare and the fresh output and dry one increased by more 22.44% and 40.57% than one of CK; and that the profit was the best as the amount of Si, Ca, K fertilizer application was 750 kg per hectare and input/output was in turn 6.53 and 18.81 as fresh and dry. The suitable amount of Si, Ca, K fertilizer application thongh regression was 2086.95kg(per hectare) with 24.79 ton fresh output and 2062.2kg with 6.53 ton dry output. |
