改良剂对地栽月季生长和城市绿地土壤性状的影响OA
Effects of Soil Amendments on Growth of Field Rose and Urban Greenspace Soil Properties
[目的]探究不同改良剂对月季生长的影响及其对城市绿地土壤的改良效果.[方法]以'深圳红'月季品种 2 年龄植株为试验材料,通过施用有机肥与不同的改良剂进行地栽试验,测定 0～56 d各处理月季生长、开花状况以及土壤的理化性质指标,评价不同土壤改良剂的应用效果.[结果]改良剂处理对月季生长和开花有显著影响,其中改良剂 2(由弃土发泡颗粒、生物炭、生化黄腐酸、聚丙烯酸钾以 50∶25∶5∶1 质量比制成)处理月季在56 d时的株高、茎粗、冠幅和叶片SPAD值分别较对照增加了 7.83%、19.88%、13.46%和8.05%,开花数量、花径、单朵花质量和单株花质量分别较对照增加了 28.76%、23.40%、22.22%和 60.74%.有机肥配施 2 种改良剂对种植土有显著改良效果,其中有机肥配施改良剂2 的效果最好,56 d时,改良剂 2 处理下的种植土容重较对照降低了 3.42%,有机质含量比对照提高了 100%,土壤入渗率、碱解氮、有效磷和速效钾含量分别较对照提高了 55.89%、46.67%、60.18%和 37.55%.[结论]无机肥用量 75 g/m2+有机肥用量 375 g/m2+改良剂 2 用量375 g/m2 较适宜作为城市绿地月季种植的土壤改良方法.
[Objective]The present study was done to investigate the effects of different amendments on the growth of roses and their effects on soil improvement of urban greenspaces.[Method]Two-year-old plants of the Rosa chinensis variety'Shenzhen Red'were used as the ex-perimental materials.In situ experiments were conducted with application of organic fertilizer and different soil amendments.The growth and flowering of roses as well as the physicochemical proper-ties of the soil in different treatments were maesured within 0-56 days after treeatment,and the appli-cation effects of different soil amendments were evaluated.[Result]The soil amendment treat-ments had a significant effect on the growth and flowering of roses.Among them,the plant height,stem diameter,crown width,and leaf SPAD value in roses treated with amendment 2(product made of waste soil foam particles:biochar:biochemical fulvic acid:potassium polyacrylate=50:25:5:1)increased by 7.83%,19.88%,13.46%,and 8.05%,respectively,compared to the control at 56 days after treatment.The number of flowers,flower diameter,single flower weight,and flower weight per plant increased by 28.76%,23.40%,22.22%,and 60.74%,respectively,in the treatment with amend-ment 2 compared to the control.The combinations of organic fertilizer and two amendments had a significant improvement effect on the planting soil,among which the treatment of organic fertilizer combined with amendment 2 showed the best.At 56 days,the bulk density of the planting soil treated with amendment 2 decreased by 3.42%compared to the control;the organic matter content was 2.65 times of that in the control;the soil infiltration rate,available N,available P,and available K content increased by 55.89%,46.67%,60.18%,and 37.55%,respectively,compared to the con-trol.[Conclusion]Application of 75 g/m2 inorganic fertilizer+375 g/m2 organic fertilizer+375 g/m2 amendment 2 is suitable for improving the urban greenspace soil properties for rose cultivation.
