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.
Summer is coming, and the sun is getting hotter and hotter. Sometimes I park my car in the sun for a while and then go in. It feels like a sauna, and the seat is very hot. At this time, you will see a lot of people put the sunshade on the front windshield. Does this really work? Can the sunshade be insulated?
First: in the United States station, the top three hot search words are Christmas decoration, Christmas tree, 2021 black five seconds. Needless to say about Christmas products, it looks like the black five-second seller is going to take off. Please close the sunshade, put away the small table, and make a gliding posture.
High temperature and humidity: high temperature and humidity in summer and autumn are also factors that affect the normal work of car stereos. The car is in the upper part of the dashboard, in order to avoid sunlight, the use of sunshade can achieve better results. Timely release of static electricity: more attention should be paid to the use of car stereo in winter, because the climate is dry in winter, turning on warm air in the car will cause drier, which is prone to static electricity.
As for the temperature inside the car, the Japanese Automotive Union JAF has also done relevant tests before, and found that the same car was found to be black and white respectively, and exposed to the sun for four hours with closed windows and no sunshade curtains, sampling temperature changes in the room, above the dashboard and on the roof respectively.

Therefore, in the structure of the window, in order to be able to control the illuminating effect of sunlight, the area of the window wall should not be too large. If the window area is relatively large, it should be considered to choose heat reflection glass, endothermic glass or other shading methods, such as eaves, eaves, sunshade panels, window cloths and so on to block the absorption of heat. Improve the airtightness of doors and windows and reduce the number of ventilation in the room. For example, the selection of outstanding airtight doors and windows, or the addition of closed bars on doors and windows can improve the airtightness of doors and windows. Choose the automatic control system. The automatic control system includes energy control of cold and heat source, fresh air volume control, quantity control of air conditioning system, start and stop time and operation mode of equipment, supply air temperature control, temperature and humidity setting control and so on. The automatic control system can complete the convergence management and good control of the air conditioning system, and guess the air state parameters (temperature, humidity, enthalpy, concentration, etc.) in the room surface to keep the indoor environment comfortable.
Glass curtain wall: the curtain wall of the main terminal is in the form of a 18-meter unit, which is divided into 3 small units, two self-supporting columns of the curtain wall, which are placed on the inside of the curtain wall, each column is built-in stainless steel downcomer, the first main column is covered with stone, and the indoor and outdoor ceiling runs through to the outside of the curtain wall; the finger corridor still takes 9 meters as the unit system, and the square column is used for thermal insulation and waterproofing, and the downwater pipe is placed in front and wrapped in stone. The horizontal sunshade is 9 meters long to bear the horizontal wind load, and the gravity load is suspended by stainless steel poles in each vertical seam of glass. The roof boat-shaped large daylighting roof adopts the scale of 1.5X3 meters per piece of glass, and the rest of the strip or distance daylighting roof glass uses a single piece of 1.5X1.5 meter safety scale. The aluminum plate rain canopy is arranged above the curtain wall on both sides of the corridor, and the appropriate lap length is set at the connection part of the corridor to ensure the integrity of the appearance.
