| 中文摘要: |
| 京郊地区是全国草莓种植的优势发展区域之一，目前京郊地区为了追求草莓高产，过量施肥问题十分严重，尤其底肥过量施用严重，导致肥料利用率低。因此，本研究根据草莓生长规律，通过调整底肥配方及用量，确定适合京郊草莓生产的适宜底肥配方及用量，以期实现草莓前期肥料的高效利用。研究结果表明，与FP（农户传统）产量相比，OPT1、OPT2处理草莓产量分别显著提高了18%、24%，而OPT3处理草莓产量显著降低了20.7%；OPT1处理与OPT2产量间差异不显著。在品质方面，与FP相比，除OPT3处理外，OPT1，OPT2处理草莓的VC含量显著高于FP处理，各处理间糖度差异不显著。在肥料效率方面，OPT1，OPT2处理NPK偏生生产力明显高于FP处理，而OPT3处理NPK偏生生产力明显低于FP处理，其中OPT1肥料偏生产力最大。在经济效益方面，与FP处理相比，OPT1，OPT2经济效益分别显著提高，OPT3经济效益显著降低。因此，综合草莓植株长势、产量、品质、肥料生产力、经济效益等，京郊地区草莓推荐底肥配方为18-9-18，推荐用量为225-450kg/hm2。 |

| The area is one of the advantages of regional development of the strawberry planting area in the suburbs of Beijing, in order to pursue the high yield of strawberry, excessive fertilization is a serious problem, especially the excessive application of fertilizer is serious, resulting in low utilization rate of fertilizer, Therefore, In this study, according to the law of the growth of strawberry, by adjusting the formula and the amount of fertilizer, suitable for strawberry production in suitable fertilizer formulation and dosage, in order to achieve efficient use of the fertilizer strawberry. The results showed that with FP (the traditional farmers) yield compared to OPT1, OPT2 treatment significantly increased the yield of strawberry were 18%, 24%, and OPT3 yield of strawberry was decreased by 20.7%; the differences of yield between OPT1 and OPT2 was not significant. In quality, compared with FP, the VC content of OPT1 and OPT2 treated was significantly higher than that of FP treatment, and there was no significant difference in sugar content among treatments. In the fertilizer efficiency, OPT1, OPT2 NPK as productivity was higher than FP, and OPT3 NPK as productivity was significantly lower than that of FP treatment, the maximum OPT1 fertilizer partial factor productivity. In economic benefit, compared with FP, OPT1, OPT2 economic benefits were significantly improved, OPT3 economic benefits were significantly reduced. Consequently, comprehensive strawberry plant growth, yield, quality, productivity and economic benefit of fertilizer, fertilizer recommendation in suburban area of strawberry recipe for 18-9-18, recommended dosage is 225-450kg/hm2. |
