The significant effects on stabilizing or raising grain output were obtained by extending the techniques of keeping crop seedling against drought

adjusting planting frame

using excellent varieties

applying fertilizer

and using the ridge-furrow planting method. Although the rainfall decreased by 36.1 percent compared with the general annual rainfall in the extremely dry year of 2000 in Yangou watershed

which made the grain output approached to 525.1 kg per capita. These alternatives can play the significant roles in insuring the grain security after shifting the slope land to terrace

and accelerating the process of conversion of certain cropland to forestry land and grassland in the hill and gully region in the middle of loess plateau.
