南宁市郊土壤及作物重金属污染状况研究

A Preliminay Report on the Application of Foliage Fertilizer that Saved the Rice Polluted by Sulphur Dioxide

本文研究了南宁市郊土壤和作物中铅、镉两种重金属元素的污染状况。结果表明冶炼厂周围农田土壤及稻谷受铅镉重金属污染比较严重，特别是铅污染重于镉污染，同时污染没有减弱趋势。古教塘一带农田土壤及稻谷的铅污染较轻，而镉污染较重。

Sulphur dioxide, the industrial waste gas, polluted the rice and caused the serious decrease of the rice output. In the rice boot stage, to spray the foliage fertilizer to the rice that injured by sulphur dioxide would decrease the damage of the rice effectively.
