摘要

Meanwhile, the annual loss of land to other use is 10 to 35 million ha, with half of this lost land coming from cropland.Facing such severe situation of population growth pressure plus cropland reduction, it is obvious that the only way to solve food shortage problem is to greatly enhance the yield level of food crops per unit land area through advance of science and technology.
