橡胶厂废水·污泥在蔬菜生产中的应用研究

Study on Application of Rubber Processing Wastewater and Sludge in Vegetable(Ipomoea aquatica Forsk.) Production

[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] Rubber processing wastewater and sludge are rich in N, P, K, Ca, Mg and the other nutrients, the purpose was to explore their application in vegetable production. [ Method ] Field experiment was carried out on the swamp cabbage （Ipomoea aquatica For- sk. ）. [Result] The results showed that rubber processing wastewater and sludge had some fertilizer efficiency, applying digestion sludge and irrigating with rubber wastewater increased the content of soil organic matter and raised soil fertility, the swamp cabbage had characteristics of better growth, higher plant and chlorophyll content, and its yield increased by 60.9% - 132.2%. [ Conclusion ] The study provides a scientif- ic basis for applying of rubber processing wastewater and sludge in vegetable production.
