油橄榄加工废弃物(OMW)的任意排放会造成严重的资源浪费和环境污染。合理施用OMW不仅可以改善土壤肥力,而且可减轻对环境的威胁,创造更大的经济效益。OMW施用于土壤中,可显著增加土壤有机物及可溶性有机碳的含量,改善土壤pH值及速效P、K等元素的含量,提高除草剂的利用率;可改变土壤微生物群落结构,增加微生物活动及生物量,促进土壤不稳定有机物的氧化成熟。但是由于OMW中含有较高浓度的酚类化合物,在施用时应严格控制其浓度,以降低对土壤生物的毒性。本文综述了施用OMW对土壤生化特性的影响。
Any discharge of Olive Processing Waste (OMW) can cause serious waste of resources and environmental pollution. Rational application of OMW can not only improve soil fertility, but also reduce the threat to the environment and create greater economic benefits. OMW can significantly increase the content of soil organic matter and dissolved organic carbon, improve soil pH, P and K, and improve the utilization rate of herbicides. It can change the structure of soil microbial community and increase the activity of microorganism Biomass promotes the oxidative maturation of soil-labile organic compounds. However, due to the higher concentration of phenolic compounds in OMW, the concentration should be controlled strictly to reduce the toxicity to soil organisms. This article reviews the effects of applying OMW on soil biochemical characteristics.
