Take emergency measures for disaster prevention and reduction. Pay close attention to weather changes and timely do a good job in preventing extreme weather emergencies such as low temperature and frost damage and snow disasters. Before the strong cold air comes, the greenhouse facilities should be strengthened in time, the air leakage of the film should be repaired, and multi-layer covering should be used to keep warm at night. 0.2% potassium dihydrogen phosphate solution was sprayed on the leaves at low temperature for 1-2 times to enhance plant resistance. After strong cold air, the management of ventilation, light, humidity reduction, disease prevention and extra-root topdressing should be strengthened, watering should be strictly controlled, humidity in the greenhouse should be reduced, and plant growth should be restored as soon as possible. Plants are prone to water loss and wilting in fine weather. Sunshade nets or non-woven fabrics can be used to cover the sun, heat up slowly, gradually increase light, and prevent plants from withering and dying. Open-field vegetables can be tied up according to the situation, floating cover sunshade net, straw and other to prevent frost injury, rain and snow weather can rush to harvest some vegetables, stored in indoor batches on the market.
Through E-Legend, Peugeot has created a vehicle that evokes the nostalgia of French cars and looks like it comes from the future. For example, the broken blue velvet interior looks a lot like Elvis Presley. At the same time, it shakes 16 screens on doors, sunshades and floors, and the wooden steering wheel shrinks back into the dashboard, so you can let it drive or control itself. What you want to do most is the latter, because a 456 horsepower electric motor can push it to 62 mph in four seconds and then drive 373 miles between charges.
The glass curtain wall can affect the radiation of the sun by selecting a reasonable glass material, but the effect of installing sunshade panels, shading blinds and other external shading is far greater than changing the glass material. Setting up a sunshade system on the glass curtain wall can minimize the direct exposure of sunlight, so as to avoid indoor overheating, which is one of the main measures to build and protect against heat in hot areas.
Compared with the glass multi-span greenhouse, the cost of the glass multi-span greenhouse is lower, and the quality of the sunplate is lighter. The safety is higher; the thermal insulation effect of the sun board is better; the all-steel skeleton structure is sturdy and durable, and the service life is long, but the light transmission efficiency of the sun board decreases with the use time; the sun board needs to be replaced after serious aging; thermal insulation facilities are also needed in winter. Intelligent greenhouse is a kind of modern planting which integrates data acquisition, central calculation and automatic control of equipment. High-tech intelligent greenhouse is generally equipped with high automation facilities such as external sunshade system, internal masking system, internal heat preservation system, forced ventilation and cooling system of wet curtain fan, top ventilation system, heating system, power distribution / control system and so on. The managers input the data and control parameters needed for planting crops into the computer, and the intelligent greenhouse can realize unmanned automatic operation.
Temporary shading of rural domestic sewage treatment equipment is the installation of lightweight curtains, plastic blinds or pendants at the window, while sexual shading is the installation of sunshades in various forms in the window. The facilities of sexual sunshade system can be divided into active form and fixed form according to whether the components can be disassembled and moved. In recent years, the active sunshade system is widely used in buildings in our country, and the angle of the sunshade can be adjusted freely according to the annual seasonal change or the all-day sunshine change. Because of the strong flexibility of this facility, it can also be easily removed in order to get sunshine and avoid blocking the sun in the cold season. Today, with the rapid development of science and technology, there are all kinds of heat reflection glass, such as sunlight control film, coated glass, low emissivity film glass and so on.
The cab. The flat head can be turned over, the torsion bar type overturning mechanism, the driver seat, the middle seat and the helper seat are arranged in the front row of the driving room. The driver seat can be adjusted back and forth, and the seat back angle can also be adjusted. There are berths in the back row with insulated carpets, sundries, quartz clock, cigarette lighter, receiver, sunshade, inner rearview mirror and curtain frame. Both doors are equipped with locks, door glass can be raised and lowered, triangular window and rear window glass can be opened. The front window is equipped with an electric wiper and washer, and the door is equipped with an external rearview mirror. There is instant wind, air conditioning optional.
Qinglong in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
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!
