However, the field planting mode is macroscopically embodied as small plots, single areas and long-term intensification, and is specifically embodied as a mode of agricultural management of large-scale fertilization guided by farmers according to long-term experience in the past, and the fertilizer throwing structure is unreasonable, so that a great amount of resources are wasted and the agricultural production cost is increased.
