河北省设施栽培雨水利用初探

Preliminary Study on the Rainwater Utilization in Protected Cultivation

从降雨资源、国内雨水富集叠加技术成果及政府政策上论证河北省发展雨水集蓄利用工程的可行性,阐述了设施栽培农业利用雨水灌溉集雨系统组成及设计,并计算了该系统下的集雨量。最后,提出塑料大棚集雨利用技术中存在的问题及对策。

The feasibility of developing rainwater collecting utilization project in Hebei province was demonstrated from the aspects of rainfall resources,domestic technology results of rainwater enrichment superposition and government policies.The composition and design of rainwater collecting system by using rainwater irrigation in protected cultivation agruiculture were expounded and the collected rainwater amount in this system was cacultated.Finally,the exsisting problems and countermesures in rainwater collecting utilization technology in plastic shed were put forward.
