| 大棚卡槽的使用细节，蔬菜大棚用现在比较时髦的话来说是温室,很多瓜果蔬菜，都可以无忧无虑的尽情成长，但是您只看到组建成的温室，您又知道要建成一个温室需要多少的幕后工作吗? Greenhouse card trough use details, greenhouse with vegetables is now more fashionable, many fruits and vegetables, can be carefree growth, but you only see the greenhouse built, you know how much work to build a greenhouse behind the scenes? 一、为便于通风换气等管理工作，大棚顶膜与裙膜分开覆盖，通常采用三幅式覆膜，即一幅顶棚膜和左右两边两幅裙膜。顶棚膜宽7.5—8.0米，裙膜宽1.2米。先将两侧的裙膜装上，用卡槽卡住，再将顶膜盖上，两端用弹簧卡槽卡牢，每个拱架之间用压膜线(带)压住，在顶膜与裙膜交接处要重叠20—30厘米，将顶膜压在裙膜外侧，顶膜的两侧可装上摇膜杆，便于撩开顶膜通风换气。裙膜着地部分要用泥土封压。大棚覆盖时应选择无风天气进行，以免风吹不利盖膜或撕坏棚膜，盖后压好压膜带。 First, in order to facilitate the management of ventilation and ventilation, the roof film and the skirt film are separately covered, usually using three sheets of film, that is, a roof film and the left and right sides of the two skirt film. The ceiling film width is 7.5 to 8 meters, and the skirt film width is 1.2 meters. Firstly, the skirt film on both sides is fitted, clamped with the clip groove, and then the top film cover is clamped with the spring clip groove at both ends. Each arch frame is compressed with the compression line (band). At the junction of the top film and the skirt film, the top film is overlapped by 20-30 cm. The top film is pressed on the outside of the skirt film, and the two sides of the top film can be fitted with rocker poles, so as to lift the top film for ventilation. The part of the apron should be sealed with earth. Covering the greenhouse should choose windless weather, in order to avoid the wind blows unfavorable cover or tear the film, after the cover pressure film belt. 二、大棚放风通气时，先将顶膜边向上撩起，温度再升高时，再将裙膜放下。盖膜时先将裙膜夹好或系紧，再放下顶膜。撩膜盖膜按相反顺序进行。 2. When ventilating in the greenhouse, lift the edge of the ceiling film upward, and then when the temperature rises again, put down the skirt film. When the film is covered, the apron should be clamped or fastened, then the top film should be lowered. The membrane is covered in reverse order. 三、大棚建好后在大棚四周开挖深沟，降低地下水位，以利于棚内蔬菜生长。 3. After the greenhouse is built, deep ditches are excavated around the greenhouse to reduce the groundwater level so as to facilitate the growth of vegetables in the greenhouse. 四、大棚使用期间，因久晴无雨，棚膜上面沾满灰尘，直接影响采光。据试验表明，10个晴天后，大棚顶膜冲洗处与未冲洗处透光率相差25%，因此，要定期清洗棚膜，保持棚膜清洁干净，这是提高大棚使用效果的重要手段之一。 Four, during the use of greenhouse, due to the long sunny rain, the film is covered with dust, which directly affects daylighting. According to the experiment, after 10 sunny days, the light transmittance of the roof film flushing place is 25% different from that of the non-flushing place. Therefore, it is one of the important means to improve the use effect of the greenhouse to wash the film regularly and keep the film clean. |
