早在2007年,中央一号文件就明确提出“加大土地复垦、整理力度。按照田地平整、土壤肥沃、路渠配套的要求,加快建设旱涝保收、高产稳产的高标准农田。”这无疑表明,田地平整对发展现代农业具有非常重要的意义。进行农田土地平整,可以有效改善农田表面状况,提高农田灌溉水的利用率,有利于控制杂草和虫害,提高化肥使用效率,减少环境污染,实现精细地面灌溉。但人工平整农田土地耗资很大、费工多、 As early as in 2007, the document No. 1 of the Central Government explicitly proposed: “We should step up land reclamation and rearrangement and speed up the construction of high-standard farmland with high, stable and high yield according to requirements of farmland leveling, fertile soil and road and drainage facilities.” It is no doubt that the formation of the field is of great importance to the development of modern agriculture. Land leveling of farmland can effectively improve the surface condition of farmland, increase the utilization rate of farmland irrigation water, control weeds and pests, improve fertilizer use efficiency, reduce environmental pollution and achieve fine surface irrigation. However, the land for agricultural land leveling is expensive and requires more labor.
