Techniques of redistributing water and increasing yield on Loess Plateau

Based upon the fact that rainfall is 250～600mm,run off 13.7 billion cubic meter,water resource 484.58m³ per person on Loess Plateau,several redistributing water measures including the building up fertilizer, ratation cropping,drought-resistant breeding,intermittent fallow,run-off agriculture,irrigation and chemical techniques were expounded.It provides a theoretical basis for the development of water-saving agriculture.
