Zhaojiaoyao Village, Jiajiaying Township, Xuanhua County is located in the hilly area of northwestern Hebei Province where ten years and nine early mornings are pasture. The dry slopes rely on natural precipitation to maintain agricultural production, and the grain output has remained low and unstable for a long time. Since 1980, with the help of the Bajia Agricultural Institute in Zhangjiakou and the Xuanhua County Science and Technology Commission, a study on dry farming techniques has been carried out. Finally, a set of new agricultural technologies for deep-plowing and fallow farming has finally been worked out. During last year’s severe drought, Out of power. 4 acres deep subsoiling millet, average yield 128.5 kilograms. More than the average arable land per mu
