Greenhouse ventilation management: Spring outlet size can not be completely defined by a particular data because different greenhouse structure, timing and speed of cooling is different. Camber larger greenhouses, as appropriate camber shed surface heat flow easily along the upper part of the discharge of greenhouse films, even if leaked mouth is small, it can achieve better results leaked. And the longer the low planting years old shed, because greenhouse camber smaller shed surface is relatively flat, hot air shed leaked discharge port speed from slow monomer greenhouses offer, shed temperature is high. Typically, this will be at the top of the greenhouse leaked mouth open to 40 cm wide, only with a higher altitude, camber larger greenhouses open to the same outlet 30 cm leaked effect. Greenhouse ventilation management: Spring winds more monomer greenhouses, leaked mouth attention to wind. Increase the density of monomer greenhouses leaked rope manufacturers, but leaked rope is best to use a larger friction wide strips of cloth as well, this cloth while playing slipknot fixed films, friction large, Slipknot is not easy to loose big wind . Many farmers use convenience as windproof nylon rope rope monomer greenhouse construction, because the friction is small, farmers should be appropriate to increase the density of nylon rope leaked, and fixed, to prevent air being blown together. At the same time, farmers must pay attention to check in at any time during windy weather to prevent leaked Rope slack move outlet is closed.
