  11. The agricultural production holds an important position in baoding area, winter wheat and summer corn are the main grain crops and cotton is the main cash crop. the water resources used in agriculture include rainwater resources used directly by crops and surface water resources or underground water resources which is used through irrigation. there have been lots of rainwater waste because of lacking in research on rainwater resources utilization and in perfect engineering technology in baoding area. to make full use of rainwater is important to alleivate the water resources crisis and improve the ecological environment, the main objectives can make more rainwater turn into soilwater that can be utilized by crops directly and decrease the crops requirments for the surface and ground water resources
