soil water properties are excellent and crops have a prop-er water environment.The field water condition and its effect on crop yield are appraised anddryland productivitv is estimated.The results show that
the rate of field water deficiency is 30%in the east and 10%in the west;in current condition of productive forces
the potential produc-tivities in dryland are 5330~6330kg/hm2 and 7700~9000kg/hm2 for wheat and corn respec-tively
