6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus saving energy and reducing consumption. 5. Heat preservation and heat relief: electric shutter windows can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
Felt quilt in order to achieve a good thermal insulation effect, can be covered with a layer of non-woven fabric or sunshade net and other thermal insulation materials, in the presence of very low temperature weather, you can choose to add “shed” to heat preservation. Although the work of heat preservation in cloudy days is important, it should not be blind and needs reasonable regulation and control. In a snowy day, the night temperature is easy to rebound, the plant accumulates less photosynthetic nutrition during the day, but consumes more at night, so it is easy to grow poorly. Therefore, it is very important to regulate the night temperature in overcast, rainy and snowy weather.
●?? One is to clear the ditch and reduce dampness. Clean up the ditches in time to reduce the field humidity and prevent waterlogging damage caused by stagnant water in the field; the whole bed in the greenhouse is covered with plastic film, and the ditch is covered with dry straw to reduce the humidity in the greenhouse. The second is to keep warm against the cold. Pay attention to the heat preservation of vegetables, check the leakage of the greenhouse film, close the shed at the right time in the morning and evening, properly uncover the film and ventilation when the temperature is high, adjust the temperature and humidity in the shed, and increase the light. Open-field vegetables can be tied around the waist, floating surface covering sunshade net, straw and other anti-freezing. Third, strengthen management. Do a good job in pruning vegetables in the field, beating leaves, hanging vines, fertilizing, cultivating soil and so on. Fourth, post-disaster management. After the freezing weather of rain and snow, timely ventilation and humidity drop, spraying to prevent disease, frostbite disease cleaning and other measures, strict control of watering, sunny weather should pay attention to timely return to the curtain to prevent plant seedlings from withering and dying.
Use a sunshade. Direct sunlight is the main culprit that causes leather seats to fade and crack. Put an open sunshade in front of the windshield to protect the leather from sun exposure and extreme heat. As long as the car is exposed to the sun for a long time, turn on the sunshade, such as when parking in the company parking space during the day. 
The interior design of the Lexus LS500 is even bigger for the traditional breakthrough. in terms of the composition of the profile, for the first time, the area in front of the co-pilot is also included in the main visual features of the dashboard, the sunshade above the center console is extended to both sides, and the panel on the side of the co-pilot echoes with the LCD screen.
