摘    要:在施用定量铬渣钙镁磷肥的基础上,添加序列浓度的六价铬,盆(或微区)栽小麦、水稻、小白菜,根据这些作物的生长反应和收获物中的六价铬含量,并参照有关的卫生标准,建议施用铬渣制钙镁磷肥中六价铬的控制指标是,对旱作物,六价铬最大添加量为20ppm;对水稻,六价铬最大添加量为100ppm。

关 键 词:土壤污染  六价铬  施用指标  残余物

Abstract:A research was conducted to establish the standard of the amount ofhexavlaent chromium in calcium magnesium phosphate made of chromic residue as it wasapplicated to acid soil. Rice, wheat and Chinese cabbage were used as indicator plants.The results of soil culture and plot experiment showed that the maximum amount of addedhexavlaent chromicum was 20ppm for land crops and 100ppm for rice. Removal ofchromium in parts of three crops: root>stem>seed. Remainder of chromium in food partsof three crops: Chinese cabbage>wheat>rice. About 94-96% of chromium remained insoil.
Keywords:heavy metal pollution  application guidelines  chromic residue  remainder
