Using "Three-dimensional Space Resources" for Fenlong Technology to Improve Grain Ecology and Expand Human Living Spaces

Fenlong Technology has been applied to increase yield by 20%-50%, improve quality by 5%, and retain water by 100% in 40 kinds of crop cultivated land and saline-alkali land in 26 provinces of China. This paper clarified for the first time the scientific theory system of Fenlong Technology using three-dimensional space resources "Fenlong Agricultural Nature Theory" and the development of the relative "limits" of agricultural growth, which provides a huge power support and natural force for expanding human living spaces. Through inventing and creating a scientific and technological system of farming tools, farming machinery, farming modes, and magic weapons for cultivation, Fenlong Technology can increase grain, promote ecological development, and greatly expand the living spaces of the Chinese nation and achieve sustainable development. Using Fenlong Technology, China has expanded from the current single "cultivated land agriculture" to the "big pattern agriculture" of Fenlong "cultivated land + saline land + degraded grassland + marginal land + desertified land + river water", flexibly used 147 million ha of "three-dimensional space resources" of land, and the newly increased food, meat, and fish can feed 300 million to 400 million people, increased the water storage by 100 billion m3, and reduced the collection of groundwater by 20 million to 60 billion m3.
