At present, the open field vegetables grown in the field are kale, green vegetables, snow vegetables, mustard, cauliflower, broad beans, peas, celery, heading cabbage, yellow sprouts, carrots, onions and garlic. First, in terms of management, we should do a good job in shallow ploughing, soil cultivation, weeding, topdressing, and timely drainage after rain. Second, cauliflower, Chinese cabbage, yellow sprouts, carrots, onions and garlic can be harvested and listed in batches in time, while doing a good job of anti-freezing and heat preservation, covering the floating surface or small arch shed with straw, greenhouse film, sunshade net or non-woven cloth at night when the temperature is low, and rice straw bundles are used for heading Chinese cabbage to ensure the compactness of the ball and avoid frostbite.
Zhang Wei, deputy general manager of the Urban Deputy Central Station Integrated Hub Construction Management Co., Ltd., said that the “Jingfan” roof has built a perforated sunshade, which balances the cold and heat load and can rationally control the indoor light and heat environment. It is estimated that by adopting the “Beijing sail” scheme, the heat load can be reduced by 5.2 million kilowatt-hours per year, which is equivalent to the summer cooling capacity of 3200 household air conditioners, and the power consumption of lighting can be reduced by about 486000 kilowatt-hours per year.
The shading design should be based on the climate characteristics of the area, the use requirements of the room and the orientation of the window. The effect of sunshade facilities on shielding solar radiation heat not only depends on the shading form, but also depends on the structure, installation location, material and color of sunshade facilities. The shading device can be set to permanent or temporary. Permanent sunshade devices include setting various forms of sunshade panels in the window; temporary sunshade devices include lightweight curtains and various metal or plastic blinds in the window. Permanent shading facilities can be divided into two types: fixed and movable. The movable sunshade facility can adjust the angle of the sunshade according to the change of season, the time of day and the gloom of the sky. Shading measures can also use a variety of heat reflection glass and coated glass, sunlight control film, low emissivity film glass and so on.
Shanghai Luotaofu PC sunlight board integrates daylighting, heat preservation 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 the aspect of greenhouse construction, there are greenhouses built with sun panels, greenhouse with gables using sun panels, and greenhouses built with gables and sidewalls using sun panels. In terms of greenhouse efficacy, there are production-oriented greenhouses, trade greenhouses based on flower trading centers, and greenhouses based on scientific research. Sunpanels are a wide range of building materials that can also be used in sunshades and canopies. Zhejiang general-purpose solar panel
There is more suitable for picnics or barbecue, you can prepare lunch boxes, fruit, cloth, and so on to go there for a picnic, and it feels good. We went there to barbecue, bought food and carbon, and the barbecue grill went there. Rent a barbecue stove and sunshade at the entrance. (uncle also gave away a piece of table cloth and alcohol wax, which was lit soon.) A total of 50 yuan (quietly telling you that you can bargain) the feeling of their own barbecue is still very good!
Tents are necessary ritual items for picnics, and it is critical to take children out with sunscreen. Tents can act as sunshades and allow children to take a nap inside, mainly because no child does not like tents.
Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
