| 摘 要： | 为加速矮生沿阶草的繁殖和推广，通过N、P、K 3因素不同配比施肥，研究不同NPK的配合施用对矮生沿阶草生长的影响。综合叶片生长速率、出叶速率、叶绿素含量、单位时间内新根发生数量、根系活力等测定结果认为，NPK适当配比才能促进其正常生长，处理N2P2K1、N2P2K2能较好地调节矮生沿阶草地上、地下生物量分配，促进植株快速生长。适宜矮生沿阶草生长的专用肥配方为N、P2O5、K2O按照7:3:（8~8.5）配比。 |

| Abstract: | In order to accelerateOphiopogon japonicus 's growth and propagating rate,growth situation of Ophiopogon japonicus treated with 27 nutrient solutions containing different concentration of N,P,K was studied in pot trial. From the indexes of leaf elongation rate,leaf expanding rate,chlorophyll content,renascent root number and root activity,it was showed thatOphiopogon japonicus could grow normally only with suitable NPK mixture ratio,the treatments of N2P2K1 and N2P2K2 could regulate belowground and overgrou... |
| Keywords: | Ophiopogon japonicus combined application of nitrogen phosphorus potassium growth rate |
