城市污水污泥含有许多有价值的营养物质，可用于种植能源作物。大剂量污水污泥的应用可能会造成环境污染，尤其是营养物污染。多花玫瑰和弗吉尼亚扇瓣是营养需求较高的植物。利用城市污水污泥种植能源作物将能够回收这些有机废物中的营养物质。本研究的目的是评估野蔷薇对城市污水污泥中大量元素的利用。 “Jatar”（Rosa multiflora Thunb. ex Murray）和弗吉尼亚扇瓣（Sida hermaphrodita Rusby）。在为期6年的现场试验中，应用了四个水平的污泥施肥：0、10、20、40、60 Mg DM污泥。哈(-1)。种植能源作物前施用一次污水污泥。由于污泥中钾含量较低，单次追施钾肥100公斤。 ha(-1) 以 40% 钾盐 (KCl) 的形式施用于每个地块。该研究涉及能源工厂对污水污泥中 N、P、K、Ca、Mg 和 Na 的产量、吸收和使用的评估。结果发现，污水污泥剂量的增加显着提高了野蔷薇和弗吉尼亚扇瓣的生物量产量。弗吉尼亚扇瓣的产量比野蔷薇高一倍半。污水污泥剂量的增加显着提高了这些植物对 N、P、K、Ca、Mg 和 Na 的含量和吸收。多花玫瑰和弗吉尼亚扇瓣作物对常量营养素的最高吸收量为 60 毫克干物质。 ha(-1) 施肥剂量。结果表明，弗吉尼亚扇瓣对污水污泥中 N、P、K、Ca、Mg 和 Na 的利用程度高于野蔷薇。分析表明，由于弗吉尼亚扇形花具有更高的产量、生物累积性和大量营养素的吸收，因此可以更有效地“净化”基质中可能对环境构成威胁的过量营养素。
Municipal sewage sludge contains many valuable nutrients which can be used in the cultivation of energy crops. Application of large doses of sewage sludge can be a cause of environmental pollution, especially with nutrients. The multiflora rose and the Virginia fanpetals are plants with high nutritional requirements. The use of municipal sewage sludge in the cultivation of energy crops will allow recycling the nutrients from this organic waste. The aim of the study was to evaluate the use of macroelements from municipal sewage sludge by the multiflora rose var. "Jatar" (Rosa multiflora Thunb. ex Murray) and the Virginia fanpetals (Sida hermaphrodita Rusby). Four levels of sewage sludge fertilization were applied in the 6-year field experiment: 0, 10, 20, 40, 60 Mg DM sludge . ha(-1). Sewage sludge was applied once before planting energy crops. Due to the low potassium content in sewage sludge, a single supplementary fertilization with 100 kg K . ha(-1) in the form of 40% potassium salt (KCl) was applied on each plot. The study involved the evaluation of the yield, uptake and use by energy plants of N, P, K, Ca, Mg, and Na from sewage sludge. It was found that the increasing doses of sewage sludge significantly raised the multiflora rose and the Virginia fanpetals biomass yields. The yield of the Virginia fanpetals was one and a half times higher than that of the multiflora rose. The increasing doses of sewage sludge significantly raised the contents and uptake of N, P, K, Ca, Mg, and Na by these plants. The highest uptake of macronutrients by the multiflora rose and the Virginia fanpetals crops was determined for 60 Mg DM . ha(-1) fertilization dose. The results show that the Virginia fanpetals used N, P, K, Ca, Mg, and Na from the sewage sludge to a greater extent than the multiflora rose. The analyses indicate that due to the greater yields, bioaccumulation and uptake of macronutrients, Virginia fanpetals is more effective in the 'purification' of the substrate from excess nutrients that may pose a threat to the environment.
