在蔬菜作物一定的生育阶段,大量的灌溉废水积聚在小块地块上,导致田间淹水,使土壤通气性不良,作物根系缺氧,以致造成减产。例如:苗期的番茄,根系缺氧一天就会造成减产。所以,在田间排水不良和蒸腾蒸发量不高的情况下,相对蔬菜作物而言过多的污水灌溉就会成为一个问题。污水经处理后,悬浮物浓度在13—62毫克/升,而且颗粒细小、多呈有机物。这些
During certain growth stages of vegetable crops, large amounts of irrigation wastewater accumulate on small plots, leading to flooding in the fields, poor soil aeration, and lack of oxygen in the crop roots, resulting in reduced production. For example: seedling tomato, root anoxia will result in reduced production. Therefore, in the field of poor drainage and transpiration evaporation is not high, compared to vegetable crops, excessive sewage irrigation will become a problem. After treatment of sewage, suspended solids concentration of 13-62 mg / l, and small particles, mostly organic matter. These ones
