Abstract: In order to solve the problem such as aging establishment, inconsequent structure, illogical parameter, laggard irrigating technique, etc, establishment types and irrigating mode of QinHuangdao, ShanHaiguan, Changli and Luanhe of seashore plain in Hebei province were researched in this paper. The evolvement and irrigating mode of this subarea were known. Through analyzing the researched facts, it is found that ideal establishment type is the fourth heliogreenhouse and its suitable front roof angle is 33°5′~33°18′, back one is 34°~35°. Such primary technical parameters were raised to satisfy the decision-makers for constructing new greenhouses and reconstructing old greenhouses.
