| 棚膜维护
在大棚利用历程中，细致不要用锋利物在棚膜上碰撞，以免划破棚膜。万一棚膜出现裂口时，可用粘合剂修补或用透明胶带修补。而聚乙烯膜可用聚氨酯粘合剂举行修补。常常连结棚膜的干净，通常棚膜利用二三年后，必须调换，以免影响透光率，大棚种植效益欠安。大棚冬春育苗要用新膜。 The 1. film in the greenhouse using maintenance process, do not collide in the films with detailed sharp objects, so as not to cut film. If the film cracks, can use transparent tape adhesive to repair or repair. Polyethylene film can be repaired with polyurethane adhesive. Often linked to clean film, usually used for two or three years, must be changed, so as not to affect the transmittance rate, greenhouse planting benefit is not good enough. In winter and spring, new film should be used in greenhouse. 2.棚架维护 钢架大棚应每年刷1次防框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具锈漆，尤其是过细是生锈部件和易生锈的连接部件。水泥大棚的棚架内嵌的钢丝、竹片袒露，应举行打磨、包裹，以免划破棚膜，个别断裂的单架应及时更换，以免影响整体的牢固性。竹木大棚和水泥大棚等还应细致拱柱、立柱等连接处的铁丝、螺栓的牢固性，也应细致防锈。 2. maintenance scaffolding steel shed should brush 1 times a year of rust, especially fine rust parts and connecting parts easy to rust. The steel wire embedded in the scaffolding of the cement shed and the bamboo pieces are exposed, and should be grind and parcel so as not to break the film. The single frame of individual fracture should be replaced in time so as not to affect the firmness of the whole. Bamboo and plastic shed and cement shed should also be careful about the firmness of wire and bolts at the connection points of arch columns and columns, and rust prevention should also be meticulous. 3.地锚线、压膜带的维护， 地锚线和压膜带如较松动液压钢坝 或断裂时，应及时紧固或更换。科学的存储才能有效的延长其使用年限。 3. anchor lines, with film maintenance, anchor line and film with such as more loose or broken, should be timely to tighten or replacement. Scientific storage can effectively extend its service life |
