摘　　要：为优化园林绿地植物管养技术模式,筛选适用于园林植物的环境友好型肥料,通过盆栽培养试验,研究了不同类型肥料(复合肥、有机肥、缓释肥、AMF真菌菌剂、微生物菌剂、生物有机肥、蚯蚓养殖渗沥液)对园林植物白兰Michelia×alba、粉花蒂牡花Tibouchina urvilleana、矮牵牛Petunia hybrida生长的影响。结果表明,复合肥、复合肥+有机肥、缓释肥可分别明显促进白兰、矮牵牛、粉花蒂牡花的生长。与对照相比,施加蚯蚓养殖渗沥液后,白兰根鲜质量增加了0.66倍,粉花蒂牡花的根、茎和叶的鲜质量分别增加了1.32倍、0.65倍和0.96倍,土壤生物结皮的厚度和覆盖率分别增加了1.63倍和0.44倍。根据蚯蚓养殖渗沥液的综合施用效果,结合其环境友好、资源化利用、呈液态等特点,发现蚯蚓养殖渗沥液在促进园林植物生长方面具有较大的应用潜力。To optimize the management technology model of plant in round necked green spaces and screen environmentally friendly fertilizers suitable for garden plants.The effects of different fertilizers(compound fertilizer,organic fertilizer,slow-release fertilizer,AMF fungal agent,microbial agent,bio-organic fertilizer,infiltration liquid from earthworm culture)on the growth of garden plants Michelia×alba,Tibouchina urvilleana and Petunia hybrida were studied through pot culture experiments.Results showed that compound fertilizer,compound fertilizer+organic fertilizer,and slow-release fertilizer can significantly promote the growth of Michelia×alba,Tibouchina urvilleana and P.hybrida,respectively.Compared to the control,after applying infiltration liquid from earthworm culture,the fresh weight of the roots of the white lily increased by 0.66 times,the fresh weight of the roots,stems,and leaves of the pink flowered peony increased by 1.32 times,0.65 times,and 0.96 times respectively,and the thickness and coverage of the soil biological crust increased by 1.63 times and 0.44 times respectively.Based on the comprehensive application effects of infiltration liquid from earthworm culture,combined with its environmentally friendly,resource-utilization,and liquid-state characteristics,it has been found that infiltration liquid from earthworm culture has significant potential in promoting the growth of landscape plants.
