摘要
我国农用地重金属污染问题日益突出,每年因重金属污染而导致粮食减产达100多万吨,被重金属污染的粮食超过1200万吨,造成的经济损失巨大。针对农用地的土壤污染修复问题,根据"中度污染农田表层土壤有效态重金属控制技术"、"中度重金属污染农田粮食作物安全生产技术"以及"中-重度重金属污染农田非粮作物生产技术"的研究指导思路,提出采用小试→中试→示范的研究方案。
The problem of heavy metal pollution in agricultural land in China has become increasingly prominent.Due to heavy metal pollution,the grain production has been reduced by more than 1 million tons,and the grain contaminated by heavy metals has exceeded 12 million tons,causing huge economic losses.For the problem of soil pollution restoration of agricultural land,according to the＂Control technology of available heavy metals in surface soil of moderately polluted farmland＂,＂Safe production technology of food crops in moderately heavy metal contaminated farmland＂and＂Production technology of non-grain crops in medium-heavy heavy metal contaminated farmland＂,we propose a research program using a small test,a pilot test,and a demonstration.
