摘要

棕榈油厂废水(POME)的排放可能会造成环境污染，因此棕榈油厂中含有高总固含量的POME废物具有作为有机改良剂、蚯蚓堆肥或处理后的POME污泥(TPS)的潜力。本研究的目的是确定有机改良剂的最佳处理效果和玉米的生长性能，并分析收获后施用有机改良剂对土壤理化性质的影响。试验采用随机完全区组设计(RCBD)， 4个处理，6个重复。治疗方法包括;处理1:对照，处理2:FVC 2 kg，处理3:TPS 2 kg，处理4:FVC 1 kg + TPS 1 kg。结果表明，2 kg FVC (T2)处理显著改善了土壤物理性质和抗剪强度。阳离子交换量(CEC)、养分有效性和玉米生长性能均有提高。在抗剪强度分析中，T4处理的法向应力较高，为319.4 kN/ m2。综上所述，植被覆盖度有机肥和植被覆盖度与TPS混合施用在改善土壤理化性状和提高玉米生长性能方面效果最好，且具有成本效益和环境友好性。

Influence of palm oil mills effluent (POME) sludge vermicomposting on soil physicochemical properties and Zea mays growth performances

Discharging the palm oil mill effluents (POME) might result in environmental pollution, thus the POME wastes that had high total solids, abundant in oil palm mills, potential to be utilized as an organic amendment, vermicompost or treated POME sludge (TPS). The objectives of this study are to determine the best treatment effect of organic amendments and Zea mays growth performances, and to analyse the soil physicochemical properties after application of treatments after harvesting. This experiment was carried out in Randomized Completely Block Design (RCBD) with 4 treatments and 6 replications. The treatments consisted of; treatment 1: Control, treatment 2: 2 kg FVC, treatment 3: 2 kg TPS and treatment 4: 1 kg FVC and 1 kg TPS. Based on the result, 2 kg FVC (T2) treatment showed significant improvement in soil physical properties and soil shear strength. Cation exchange capacity (CEC), nutrients availability and and Zea mays growth performances were also improved in this experiment. For shear strength analysis, T4 treatment showed high normal stress at 319.4 kN/m 2 . In conclusion, FVC organic fertilizer and mixed FVC and TPS indicated the best amendment in improving soil physicochemical and enhanced Zea mays growth performance and it is cost effective and environmentally friendly.
