Although, there are some minor complaints in the process. “before the introduction of the policy, I saw someone cooking hot pot on the lawn, hurting the grass. When they left, they also left some rubbish. ” Ms. Mak, a citizen, said. In view of this situation, according to the person in charge of the Yuntai Garden Management Center of Baiyunshan Scenic spot, the tent area of the park will be in charge of a fixed area, a fixed period of time and a special person. At present, two large lawns in Yuntai Garden are open for citizens to set up tents from 10:00 to 4 pm on weekends and holidays. Members of the public can set up tents and picnics. The garden will also provide sunshade facilities and designate garbage dumping areas. Kites and fire are prohibited on the lawn.
First of all, what we have to consider is the orientation of the balcony. If the balcony at home is sunny, and the light is particularly good, then it is recommended to install a sunshade, so that when the sun is very strong or weekend rest, you can use sunshade to block the heat. The overall beauty and neatness, which can highlight the elegance and formal sense of modern architecture, has become a popular choice for sunshade inside many modern buildings. Sunshade electric canopy curtain outside the sun room is generally divided into two categories, one is folding electric canopy curtain, the other is reel electric canopy curtain. The main feature of the folding ceiling curtain is that it is wavy when it is opened and folded together when it is folded. 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.
It can reduce the harm of cold current. When the temperature in the shed is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. Open fire can not be used when heating, in order to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken. Prevent seedling frost injury or overgrowth; cover should be removed properly during rainy days.
Now the weather is getting hotter and hotter, many people would rather stay at home and not go out, and for some people who drive to work, it is really a very painful thing. Every time the car door is opened, it is like a sauna. So when car owners park, they will choose to take the sunshade out to block the sun to avoid the excessive temperature in the car, so is the sunshade really useful? Come and have a look with the editor.
From the analysis of the environmental factors closely related to plant growth in greenhouse project, different temperature and humidity will have a direct impact on plant growth. Therefore, how to meet the requirements of different crop growth environment has become the main way to improve the production potential of greenhouse and realize factory planting. The intelligent greenhouse control system can not only monitor the internal environmental data of the greenhouse, set the upper and lower values of various environmental indicators, and remind managers of the abnormal situation of the greenhouse environment, but also work together by controlling the external sunshade, internal shading, internal thermal insulation, top natural ventilation system, fan water curtain forced cooling system, heating system and so on, so as to make the internal environment of the greenhouse within the scope of our design.
