农田重金属镉对农田的种植具有非常大的危害,随着时间的推移,化工行业的不断兴起,对农田水稻安全种植产生了很大危害。现有的一些判别技术并没有办法达到理想效果,必须将土壤镉积累农田水稻安全种植区判别技术充分利用,专项专治,才能让农田水稻种植区获得良性发展。 Heavy metal cadmium in farmland is very harmful to the cultivation of farmland. With the passage of time, the continuous rise of chemical industry has brought great harm to the safe planting of rice in farmland. Some of the existing discriminating techniques can not achieve the desired results. We must make full use of the discriminant technology for the safe planting of paddy soils in cadmium accumulation in soil so that we can get a healthy development of the paddy planting areas.
