一直以来,我国都十分重视农业的发展,从而促使了大量的农业研究出现,在这些研究中土壤肥力研究经久不衰,这是因为土壤肥力高低直接影响到粮食的产量。基于此,对不同施肥水平以及玉米种植对土壤碳氮含量的影响进行了分析,为提高我国粮食产量做出了应有贡献。 All along, our country attaches great importance to the development of agriculture, which has led to the emergence of a large number of agricultural research. In these studies, soil fertility research is enduring because the soil fertility directly affects the grain output. Based on this, the effects of different fertilization levels and corn planting on soil carbon and nitrogen contents were analyzed, which made due contributions to raising grain output in our country.
