在农业生产中,过量、不科学地施用化肥,会使大量肥料流入环境中,对土壤、大气、水质造成危害,同时化肥中含有的有害物质还会在植物中形成积累,威胁人类的生存与健康。因此,合理施肥,防止环境污染,在农业生产及人类生活中已处于非常重要的地位。 化肥对环境造成的污染主要是由于过量、单一施用造成的肥源浪费引起的,只有在宏观上采取一定的措施,调控化肥的种类及施用量,科学、合理地施用化肥,才能有效防止污染,保护环境。
In agricultural production, excessive and unscientific application of fertilizers will cause a large amount of fertilizer to flow into the environment, which will endanger the soil, air and water quality. At the same time, harmful substances contained in fertilizers will accumulate in plants and threaten the survival of human beings health. Therefore, rational fertilization and prevention of environmental pollution have played a very important role in agricultural production and human life. The pollution caused by chemical fertilizer to the environment is mainly caused by waste of fertilizer source caused by overdose and single application. Only when certain measures are taken macroscopically, the type and application amount of chemical fertilizer are regulated, the chemical fertilizer can be applied scientifically and rationally to effectively prevent the pollution, protect environment.
