The potentiality of increasing grain yield is restricted by drought
poor soil and bad ecologicdl conditions.Therefore
storaging water and cultivating land to improve the quality of land
and taking comprehensive technique to improve the ecological environment can lay a steady foundation for continued development of grain yield in"the two north regions.
