Discussion on Action and Potential of Fenlong Megascience in the Symbiosis between Human and Nature

[...]the nature is able to produce good food needed by human, the spatial dimension of the land is increased, the natural precipitation storage is increased, the flood and drought disasters are reduced, the eco-environment is improved, and the economic benefits are increased. Under the condition of no tillage, the yield of maize applied with nitrogen fertilizer and without nitrogen fertilizer was 9 414 and 8 568 kg/hm2 respectively. [...]the yield under Fenlong was increased by 15.5% in average compare with the control. After straw is returned to field, the application rate of chemical fertilizers and pesticides can be reduced as high as 20% -40% , forming a semi -organic agricultural products production line. [...]the ecology of farmland, rivers, lakes, etc. will be restored, improving the quality of ecological environment. The front part of the machinery can be installed with stubble cleaning machine, the middle part can be equipped with fertilizing function, the rear part can be equipped with sowing function, and the entire system can be equipped with information and intelligence. [...]high-efficiency farming and sowing will be integrated, achieving a high degree of integration of agricultural machinery and agronomy, improving greatly the agricultural labor productivity and easing the passive situation that only a few people or no people are farming.
