Abstract The environmental impact of crop wastes and the high cost of peat moss (PM) force scientists to find alternative growing media. In a pot experiment, peanut shell (PS) and corn wastes (CWs) were evaluated as growing media in comparison with PM in three different mixing ratios with washed sand. The mixing ratio were M1 = 1:1 raw material to sand, M2 = 1:2 raw material to sand, and M3 = 1:3 raw material to sand. The tested plant was lettuce (Lactuca sativa L.). The obtained results showed that PS medium contained available nitrogen (N) and phosphorus (P) higher by 121% and 38% above the PM medium. Availability of potassium (K) in CW medium was higher by 167% than PM. The EC, pH, OC, and C/N ratio of PM were higher by 227%, 4%, 128%, and 99% above the CW and by 1,473%, 9%, 74%, and193% above the PS, respectively. The highest significant values of growth parameters were recorded in PM medium. The highest total cost and lowest net profit were recorded with the use of PMM1, whereas the lowest cost and the highest net profit were obtained with PSM2. Physiochemical characteristics of peanut shell suggested that it can be economical alternative growing media for PM.

利用一些有机废物作为莴苣 (Lactuca sativa L.) 植物的生长培养基

摘要 作物废弃物对环境的影响和泥炭藓 (PM) 的高成本迫使科学家寻找替代的生长介质。在盆栽试验中，花生壳 (PS) 和玉米废料 (CW) 作为生长介质与 PM 相比，以三种不同的混合比例与洗过的沙子进行评估。混合比为M1 = 1:1 生料与沙子，M2 = 1:2 生料与沙子，M3 = 1:3 生料与沙子。受试植物是生菜（Lactuca sativa L.）。获得的结果表明，PS 培养基含有比 PM 培养基高 121% 和 38% 的有效氮 (N) 和磷 (P)。CW 培养基中钾 (K) 的利用率比 PM 高 167%。PM 的 EC、pH、OC 和 C/N 比分别比 CW 高 227%、4%、128% 和 99%，比 PS 分别高 1,473%、9%、74% 和 193% . 生长参数的最高显着值记录在 PM 培养基中。使用 PMM1 记录了最高总成本和最低净利润，而使用 PSM2 获得了最低成本和最高净利润。花生壳的理化特性表明它是一种经济的 PM 替代生长介质。
