| 温室大棚正确的覆膜方法 The correct coating method for greenhouse shelters 一、覆膜准备 One, the laminated preparation 1.人员准备。以东西长100米、跨度9.5米的温室大棚为例，至少需要20人参与。 People prepare. For example, at least 20 people are involved in the 100-meter long, 9.5 meter greenhouse. 2.薄膜准备。温室大棚薄膜共分两幅，一幅屋面棚膜，另一幅为放风棚膜。前者建议选购透光率高、无滴消雾性强、寿命长的EVA或PO等薄膜，长度以98米左右、宽度为10.5米左右为宜，并且棚膜上端要事先穿一“拉绳”。后者以选购普通棚膜为宜，长度与前者相同，宽度约3米左右，同样要备拉绳。 Film preparation. The greenhouse film is divided into two parts, one roof film and the other is a canopy membrane. The suggestion of choose and buy high light transmittance, no drop fog dispersal quality, long service life such as EVA or PO film, length 98 meters, width of 10.5 meters advisable, and top films had to wear a "pull". The latter, in order to buy the ordinary canopy membrane, the length is the same as the former, the width is about 3 meters, also should be the pull rope. 3.工具准备。钳子、紧线机、竹竿、铁丝、钢丝、压膜绳等若干。 Tool preparation. The pliers, the line machine, the bamboo rod, the wire, the wire, the pressure film rope and so on. 二、覆盖棚膜 Two, covering the covering film 覆盖温室大棚膜，宜选择晴天、无风的下午进行， To cover the greenhouse film, choose sunny weather, the afternoon of the breeze, 覆盖温室大棚屋面棚膜可分四大步骤： There are four steps to covering the roof of the greenhouse. 第一步：拉膜上棚。如：从温室大棚东边，需20人，每隔5米，依次抬起棚膜，沿着大棚前面，将棚膜一端抬到大棚西边。而后，再有其中的10人拉起（带有拉绳的）棚膜一边，从大棚底部上去，沿着拱杆向上走，将薄膜拉上棚面，剩下的10人在原地抱着棚膜，帮助另外10人拉膜。 Step 1: the lamella. For example: from the east of the greenhouse to the east, 20 people, every five meters, raise the membrane of the canopy in turn, and move the end of the canopy to the west of the tent. And then again one of the 10 people pull (with rope) films, went up from the bottom of the greenhouses, walked up arch bar and canopy face, in the film, the remaining 10 were in situ holding the films, to help the other 10 people pull membrane. 第二步：固定膜上端。方法：一人先在温室大棚东边，将钢丝固定在拉绳上，另一人在大棚西边拉动拉绳，可顺势把钢丝穿过棚膜，之后，再把钢丝这一端固定在棚西墙处的地锚上，钢丝另一端用紧线机固定。最后用铁丝，把棚膜上端捆绑在竹竿上，每隔一竹竿，捆绑1次。注意捆绑后的铁丝头要往下，避免扎破放风棚膜。 Step 2: fix the upper end of the film. Methods: one is in the east greenhouses first, pull wire fixed to the line, the other people on the west side pull the rope in the greenhouse, can be conveniently put the wire through films, after, then wire the end fixed to the shed on the west wall of anchor, steel wire with a tight line machine at the other end. Finally, with wire, the upper end of the canopy is bound to the bamboo pole, every other bamboo pole, tied one time. Note that the wire head should go down to avoid the release of the diaphragm. |
