| 为了解新型外源有益微生物对连作菊花生长和土壤调控的促进效应,以切花菊主要生产品种‘优香’为材料,使用Super ER·MI菌剂做不同处理,研究其对连作菊花植株生长、养分利用以及土壤养分累积量的影响。结果表明:Super ER·MI菌剂能提高切花菊的植株鲜重与干重,对于株高、茎粗和叶片数影响不显著,能促进连作条件下切花菊植株氮磷钾的吸收,有效提升连作条件下切花菊品质,使切花菊的花序直径增大,提高优级花比例。Super ER·MI菌剂能促使植物吸收浅层土壤中的氮元素,减少浅层土壤中的氮素累积,改善土壤的理化环境,并能提高20~40 cm土壤中养分含量,但仅能提高40~60 cm土壤中的钾含量,对于氮和磷影响不显著。其中只使用菌剂处理而不添加基质的处理相对较好,切花菊地上部的干鲜重增加最显著,花序直径增粗最多,一级花的比重增加显著,氮磷钾元素的吸收量显著得到提升。 |

| Abstract: |
| In order to explore the effects of exogenous beneficial microorganisms inoculation on chrysanthemum growth and soil conditions under continuous cropping.We inoculated chrysanthemum ‘Yuka’ with Super ER·MI microorganism, and investigated the changes of the growth and nutrient absorption of plant and the soil nutrient.The results showed that inoculation with Super ER·MI microbial agent could promote the growth of chrysanthemum ‘Yuka’, but has no significant effect on plant height, stem diameter and number of leaves.Super ER·MI microbial agent enhance the absorption of nutrients chrysanthemum ‘Yuka’ effectively, improve the ornamental quality of cut chrysanthemum, make inflorescence diameter increases, and increase the proportion of superior grade flowers.Super ER·MI microorganism could reduce nitrogen accumulation in the shallow soil and improve soil environment by promoting ‘Yuka’ to absorb nitrogen in 0-20 cm soil layer.In addition, Super ER·MI microorganism could improve the nutrient content in 20-40 cm soil layer, but has no effect on nitrogen and phosphorus content except potassium in 40-60 cm soil layer.Inoculating the Super ER·MI microorganism without additional substrate is better method:, Aboveground fresh/dry weight of chrysanthemum and proportion of first-grade flowers increased significantly;the diameter of inflorescence enlarged;And the uptake of N, P, K were improved distinctively. |
