[目的]橡胶厂废水、污泥富含氮、磷、钾、钙、镁等营养元素,探索其在蔬菜生产中的应用。[方法]在空心菜(Ipomoea aquatica For-sk.)上进行田间试验。[结果]橡胶厂废水、腐熟污泥均具有一定肥效,施用腐熟污泥、灌溉橡胶厂废水能增加土壤有机质含量,提高土壤肥力,种植的空心菜生长势较好,植株较高,叶色浓绿,叶绿素含量较高,空心菜产量增加了60.9%～132.2%。[结论]该研究可为橡胶厂废水、腐熟污泥在蔬菜生产中的推广应用提供科学依据。
[Objective] The rubber plant wastewater and sludge are rich in nitrogen, phosphorus, potassium, calcium, magnesium and other nutrients and explore their application in vegetable production. [Method] Field experiments were conducted on Ipomoea aquatica For-sk. [Result] The rubber plant waste water and decomposed sludge all had a certain fertilizer efficiency. The application of decomposed sludge and irrigated rubber plant wastewater could increase the content of soil organic matter and increase the soil fertility. The growth of the plantation of spinach was better with higher plants and dark green leaves , Higher chlorophyll content, yield of spinach increased 60.9% ~ 132.2%. [Conclusion] This study could provide a scientific basis for the popularization and application of rubber plant wastewater and decomposed sludge in vegetable production.
