Based on the test conduted in smi-arid area of loess hilly region.the southern Ningxia
the water use of crop in man-made terrace and slope land was analyzed It shows that
the change of crop production and water use efficiency is smaller in terrace
either in full rainfall year or inshort rainfall year;but for slope land
it is greater.In terrace with highest fertility
the wateruse capacity is 328.0mm
its efficiency is 0.227kg/mm;but in slope land.under the samefertility condition
its figures are 262.0mm and 0 208kg/mm separately.The way out for in-creasing production fully in terrace is to increase the amount of fertilizer applying.
