玉米是重要的粮食作物,也是世界上分布最广的作物之一,在国民经济发展中占有重要地位。近年来,随着国内外市场对玉米的需求迅速增长,我国玉米种植面积和产量呈稳步增长态势,但生产成本也在不断增加,特别是化肥投入增长较快。由于盲目大量施肥及方法不当,造成的资源浪费,环境污染,食品安全等诸多问题日益严重。因此,搞好玉米施肥,对农业生产的可持续发展意义重大。 Corn is an important food crop and one of the most widely distributed crops in the world, occupying an important position in the development of the national economy. In recent years, with the rapid growth of domestic and international market demand for corn, China’s corn acreage and output showed a steady growth trend, but the production costs are also increasing, especially in fertilizer investment increased rapidly. As a result of blind mass fertilization and improper methods, resulting in waste of resources, environmental pollution, food safety and many other issues are increasingly serious. Therefore, improving maize fertilization is of great significance to the sustainable development of agricultural production.
