For this reason, the competent departments of agriculture and forestry in many places have issued various measures to require farmers to do a good job in the prevention and remediation of crops in order to deal with the “late spring cold.” For example, for the vegetable greenhouse, the relevant departments stipulate that “when the temperature in the greenhouse is below 0 ℃ for a long time, straw bags, non-woven cloth, sunshade net and other mulch should be added in the greenhouse at night to prevent frost injury and take basin fire or fire temporary heating. At the same time, open fire can not be used when heating to prevent smoke damage, it is necessary to set up a flue to discharge harmful gases outdoors. Strengthen the coverage in time to promote heat preservation and anti-freezing. ”

“the car has been driving for a long time. I always thought that the sunshade on the front of the car could only be in front. It turned out that the bayonet could be turned into a side block after the bayonet was pulled open. However, most people will put towels and invoices here. ”

In addition to heat preservation, it is also often used as sunshade net, ⑥ sunshade net, commonly used in black and silver gray, and there are several density specifications, shading rates are different. Mainly used for sunshade and rain protection in summer. It can also be used for thermal insulation and covering in winter. The intelligent greenhouse is a modern planting environment which integrates data acquisition, central calculation and equipment automatic control system. High-tech intelligent greenhouse is generally equipped with more automated facilities, such as external shading system, internal masking system, internal thermal insulation system, strong ventilation and cooling system of wet curtain fan, top ventilation system, heating system, power distribution / control system and so on. In the work of the intelligent greenhouse, the managers input the data and control parameters needed for planting crops into the computer, and the intelligent greenhouse can realize unmanned automatic operation, automatically control the greenhouse environment and ensure the growth of barrier crops. The main results are as follows: 1. The loss of planted crops is almost zero.

When the vehicle is parked, as long as the attached sucker or rely on static electricity, the sunshade can be sucked on the front and rear windshield, which can effectively protect the dashboard, leather seats and other interior equipment while preventing direct sunlight from raising the temperature in the car. At present, in addition to the single sale of front windshield aluminum foil sunshade, but also launched a special car customization service, including windows, rear windshield and other locations, the price is not expensive, only tens of yuan to hundreds of yuan.

A part of the diaphragm is coated with a transparent reflective film, and the image and data on the dashboard transmitted from the projector can be displayed on the diaphragm as needed, which is convenient for the driver to observe, and the driver does not need to look down at the instrument when driving. The image shows that if the intelligent glass cooperates with the infrared image display system, the driver can see clearly the objects around the 2km in front of him on a foggy day. The photoelectric sunshade roof glass can automatically absorb, accumulate and use solar energy to drive the car fan when the car is driving or parking, and it can also continuously recharge the car battery.
