摘要
为探索赤泥对蔬菜生产的影响,开展了高肥料投入条件下,原状赤泥及焙烧赤泥掺混土壤对油菜生长影响的盆栽试验。结果表明:在较高肥料投入条件下添加2,4 g/kg赤泥不仅未造成油菜减产,而且赤泥的施用使油菜地上部的全氮含量提高16.5%,Vc含量提升4.5%~20.9%,虽然存在油菜地上部全磷含量降低的趋势,但降低程度未对油菜生长产生明显影响。
In order to find out the influences of addition of red mud,a waste tailing from the alumina production,on the growth and quality of cole,pot experiments of cole planting under the conditions of high fertilization were carried out. The results indicated that by adding red mud with the weight proportion of 2 g / kg or 4 g / kg,the yield of cole was not decreased while the total nitrogen in cole above ground was increased by 16. 5% and the vitamin C in cole above ground was increased by 4. 5% to 20. 9%. The total phosphorus in cole above ground was decreased slightly by the addition of red mud in the experiment condition which had no essential effect on cole growth.
