Xuanhua Town, Dengfeng City, belongs to the dry hills and hills. The steep mountain slopes within the territory are steep and thick, with thick geological conditions, deep buried groundwater and difficult exploitation. Water resources are poor, water and soil loss are serious, crop structure is single, crop yield is low and unstable . In order to adjust agricultural planting structure, increase agricultural output, increase farmers’ income, Dengfeng City, after scientific demonstration and drawing on successful experiences from other places, began to build rainwater and micro-irrigation projects in Xuanhua Town in 2001. The planned area of the project is 133hm ~ 2 and 70m ~ 3 rainwater storage pool 1000, the project total investment 2964000 yuan. The project was completed in May 2002 and all water was stored during the flood season in 2002 and played a good role in the fall. 1 engineering technical points Set rain micro irrigation project mainly includes the collector surface, gutters, diversion channels, sedimentation tanks,
