What is the principle of "storing grain in the ground and storing grain in technology"?

"Storing grain in the land" means that when the grain supply exceeds the demand, part of the land is rotated and fallow to reduce the grain output; when the grain is in short supply, the land is quickly used to produce grain, and the overall balance between grain supply and demand is maintained by increasing or reducing cultivated land. Although there is no grain production, the grain production capacity is still there. Land fallow can improve soil fertility, which is actually equivalent to storing grain production capacity in the land.

"Storing grain by science and technology" is an inevitable choice for grain production. We must take the connotative development road of relying on scientific and technological progress and increasing yield per unit area. Through the research and development of grain science and technology, we will maintain the balance between supply and demand of grain by scientific and technological means, adhere to the principle of applying one generation, reserving one generation and developing one generation, adopt corresponding technologies in time according to the balanced state of grain market, and always maintain the sustainable ability of science and technology.

Realizing soil health and scientific planting is the only way to increase grain income. It is necessary to improve the efficiency and level of grain production by protecting soil, popularizing fine varieties and adopting standardized green technology model with high yield and high efficiency.
