The organic reconstruction of soil generally means that human beings adopt engineering methods to give full play to their subjective initiative under the premise of respecting the laws of nature, so that the process of soil formation is accelerated, slowed down or reversed, and the organic process is driven by inorganic means or promoted by organic development. In actual operation, the soil can be reconstructed by using physical, chemical and biological reconstruction methods through technical means such as replacement, compounding, addition and reduction. The soil construction can increase the area of arable land, relieve the shortage of land in our country, and at the same time improve soil quality, ensure regional food security, build a new ecosystem, and ensure regional sustainable development.
