河北省滨海平原区设施类型及灌水技术发展分析

Analysis on Establishment Type and Irrigation of Seashore Plain in Hebei Province

为解决河北省蔬菜设施存在的诸如设施老化,结构不合理,参数不合理,灌水技术落后等问题,本研究对河北省滨海平原区的秦皇岛、山海关、昌黎至滦河口片的设施类型及灌水方式进行调研,了解了该分区设施类型及灌水方式的发展演变过程,并且提出适合该分区发展的理想设施类型为第四类日光温室,合理的前屋面采光角应该为33°5′￣33°18′;后屋面角应为34°￣35°。这一结果为研究区以后发展新日光温室及旧温室改造工作提供参数参考依据。

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, Shan- Haiguan, 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.
