So we should adopt the form of deep ploughing. Only in this way can we compare the photosynthesis between plants. It can do a good job of topdressing and the dilution between fertilizers in the later stage. Why should sunshade net be covered in the construction of greenhouse? Prevent rain and release hail. Can reduce the impact of rainstorm and hail, its damage to crops in the shed, cooling in summer and autumn, sunshade net can effectively block the sun, reduce the temperature in the shed, avoid the harm of strong light and high temperature to crops, 3 moisturizing and drought resistance. The speed at which air communicates with the outside world becomes slower. The relative humidity in the shed will become larger, 4 heat preservation and anti-freezing. Covering the sunshade net in winter can provide ground temperature and has the function of preventing frost. Do a good job in the overall heat preservation of the glass greenhouse: (1) if the conditions permit, the construction of semi-underground border surface can improve the soil temperature of the glass greenhouse and play a good role in soil heat preservation.

As we all know, the main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. But there are still some car owners who doubt whether sunshade really has the above effect.

There are many kinds of car sunshades on the market, not only those that can be adsorbed on the front and rear and side door glass of the car, but also those that can block the top and surrounding glass of the car at the same time. It is easy to operate, but it usually takes up a certain amount of space. There is also a car clothes or roof sunshade opened by remote control. (of course, this kind of price is often higher.)

The components and products of foaming materials for lightweight automobile, low carbon, safety protection and NVH are: headrest, dashboard, door lining, steering wheel, tire cover, luggage compartment lining, seat backrest decoration, sunshade, bumper core, air conditioning barrier board, carpet support material, roof, side guard, door inner panel energy absorption protection pad, cushion, muffler plug-in, rear engine compartment, engine shield, Power battery protection system.

The key points of the building ecological energy strategy and design for the renovation of the new German parliament building lie in the technical application and energy strategy of ventilation and lighting. After the reconstruction, the output of carbon dioxide in the building has been reduced by nearly 94%. Through the set path, the air is filtered and cooled into the building, and then the hot air and waste gas are discharged upward by the two-story dome through the building technology; natural lighting is realized by an inverted cone light reflector and a 360-degree tongue-shaped sunshade device, which is equipped with an air pipe and a heat converter, and the tongue-shaped device can rotate according to the change of the solar height angle during the day. The energy strategy adopted in the reconstruction of the building is more radical, including not only the use of solar power, but also the use of renewable “biodiesel” generators to generate electricity, coupled with the storage and recycling of geothermal heat.
