化学肥料与生态健康

Chemical Fertilizer and Ecological Health

自化学肥料出现以来,极大地保证了世界的粮食安全。由于化学肥料可使粮食单产大幅提高,从而节省了大量的农田,使得不适宜农耕的土地大量被用于生态建设。所以,化学肥料在一定程度上保证了生态环境的健康发展。化学肥料的大量使用也会带来一定的负面作用,如水体富营养化等生态健康问题,然而解决这些问题的措施是合理施用化学肥料,而不是拒绝使用化学肥料。现代农业离不开化学肥料,生态健康也离不开化学肥料。

Since the advent of chemical fertilizer,world food security has been greatly guaranteed.Besause chemical fertilizer can greatly increase the yield of grain,which saves a lot of farmland,a lot of land that is not suitable for agricultural cultivation is used for ecological construction.Therefore,to a certain extent,chemical fertilizer ensures the healthy development of the ecological environment.But the heavy use of chemical fertilizers may also bring certain negative effects,such as eutrophication of water bodies and other ecological health problems.However,the measure to solve these problems is to rationally apply chemical fertilizer,rather than refuse to use chemical fertilizer.Modern agriculture cannot do without chemical fertilizer,and ecological health cannot do without chemical fertilizer,too.
