There is still a large cold spell after the Beginning of Spring, which causes freezing and chilling injury to eggplant and fruit vegetables in the greenhouse. To this end, it is necessary to continue to do a good job in preventing cold and freezing. At this time, eggplant fruit vegetables have had a large growth, so it is necessary to cover with two layers of film in the greenhouse. Melons are more likely to be frozen than eggplant fruits, in addition to using two-channel film cover, rice straw bundles can be stacked in the skirt position around the greenhouse to enhance resistance to cold air invasion around the greenhouse; melon seedlings, which are still in the seedling raising stage, can be covered with sunshade net, straw curtain or non-woven cloth on the small arch shed at night to enhance heat preservation capacity; in case of strong cold air coming, we must do a good job of anti-freezing and heat preservation measures.

The sun board integrates daylighting, thermal insulation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large transparent lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; in terms of greenhouse efficacy, there are production-based greenhouses, trade-oriented greenhouses dominated by the flower market, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.

The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.

When the weather temperature is relatively high, we can cover the windshield of the car with sunshade. What brand of sunshade should I introduce to you? Recommend several shading and cooling cars, sunshade

At present, spray-free materials have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field.

You can directly fill the roof with soil to grow vegetables in a large area, or you can use containers to grow vegetables. It is recommended to plant luxuriant vine crops to cover the entire roof. Growing vegetables on the roof must be based on the premise of good load-bearing on the roof, and crops can not corrode concrete buildings. Each pair of ceiling curtain is composed of left and right guide rails, which drive the track when the motor starts, and the fabric is drawn by an elastic guide shaft in the middle to achieve the purpose of sunshade. Sun room sunshade system if the daylighting of the balcony at home is on the medium side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match. It can be a straight line or an arc. According to the architectural characteristics of the building, we use straight-line double-track ceiling curtain. It is not only practical for shading, but also maintains the style of architectural design.

This kind of flower planting greenhouse is widely used in most areas, especially in the south. The single-family arch shed is mainly made of plastic-coated steel pipe or galvanized steel pipe, the surface is covered with film, and air vents are added on both sides. The utility model has the advantages of simple structure, low cost, easy construction and maintenance, long service life and strong resistance to wind and snow load. Its big deficiency is that the heat preservation capacity is low and the operation cost is high in winter, so it is suitable for breeding non-tropical flowers with low temperature requirements. Of course, we can add two-layer film on the original basis, increase the curtain machine quilt and other thermal insulation equipment, sunshade can effectively improve the arch shed temperature.
