含锌钢铁渣肥对番茄产量和品质的影响

利用盆栽试验研究了含锌钢铁渣肥对番茄产量和营养成分的影响。结果表明，施用氮磷钾化肥添加含锌钢铁渣肥能够促进番茄的生长发育，可使番茄产量比单施氮磷钾化肥增产2．78％。17．03％，可溶性糖含量提高4．74％-7．11％，Vc含量降低，对蛋白质含量影响不大。

Uses of Blast Furnace Slag as Complex Fertilizer

Significant quantities of slag are generated as waste material or by-product every day from steel industries. They usually contain considerable quantities of valuable metals and materials. Transforming these solid wastes from one form to another to be reused either by the same production unit or by different industrial installation is very much essential not only for conserving metals and mineral resources but also for protecting the environment. The sustainable development concept requires a more efficient management of waste materials and preservation of environment. The paper presents the basic characteristics of slag, analyses and it＇s modification by incorporating some essential plant nutrients and the possibility of its application as fertilizer was studied.
