Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Bengbu vegetable greenhouse needs the cooperation of a variety of equipment, with the increasing temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about the cost of vegetable greenhouse in Bengbu, please contact Minghao greenhouse Engineering Construction Company directly.

In terms of interior space, Keluwei is equipped with a central console and dashboard with a multi-functional black-and-white display driving computer, a practical center console with a variety of storage spaces, a sunshade for the side windows of the passenger cabin, a comfortable roof lighting system, and a car body roof. The four reading lights in the passenger cabin provide enough light for passengers to read, and welcome pedals with lighting function and vehicle name logo Adds elegance to the interior space.

Solutions: strengthen leek field management, control temperature and humidity, timely watering, pay attention to cooling and such work in summer, greenhouse planting can be cooled and protected from the sun by building a sunshade net. Pay attention to guard against cold snap in early spring and late autumn and reduce the occurrence of frost injury. Secondly, through the vents on both sides of the greenhouse to adjust the temperature in the greenhouse, it is best to control the temperature between 20 and 30 degrees. The greenhouse can be covered with grass to keep warm in winter.

Why use sunshade? The main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, which can reduce the burning inside the car to a certain extent, and prevent leather seats and dashboards from being damaged by ultraviolet rays.

According to the regulations, the car front windshield can not use sunshade film with a light transmittance of less than 75%, and the light transmittance of other glass sunshade film can not be less than 50%, let alone mirror reflective film.

From the point of view of yield, it is mainly the anti-freezing damage of low temperature in winter. This technique is relatively easy for greenhouse loquat. For Jiangsu and Zhejiang areas, it is necessary to prepare double-film covering materials after entering December, and double-film mulching should be carried out when the cold air comes or the lowest temperature drops below 5 degrees Celsius. When the lowest temperature affected by cold air is below 0 degrees, further heat preservation work needs to be done on the basis of double film. The main measures are as follows: first, sprinkler irrigation should be carried out during the day to increase soil water content and humidity to increase heat capacity. the fog produced by the cooling of high humid air can slow down the temperature drop; second, build a sunshade net on the loquat tree. Third, the heating treatment is carried out in the shed, and the heating time is from the second half of the night to the morning. The prevention index of frost injury during flowering is to keep the temperature in the shed above 0 degrees.

The optimum temperature for strawberry seedling growth was 25 ℃ ~ 30 ℃, and the stolon stopped growing when it exceeded 32 ℃. Therefore, in the early stage, the greenhouse should do a good job of heat preservation, improve the air temperature and substrate temperature, and promote the early emergence of stolons. In the southern region, the temperature from mid-May to early July is suitable for the occurrence of stolons, during which the number of stolons is large and the interval between stolons is short. From mid-July to August, with high light intensity and high temperature, the greenhouse should be covered with a sunshade net with a shading rate of 60% from 9 am to 5 pm every day, so as to reduce the temperature and ensure the normal growth of mother and offspring. In addition, moderate shading in the later stage of seedling cultivation can meet the low temperature and short day conditions needed for strawberry flower bud differentiation and promote strawberry flower bud differentiation.

Honda near Paojiang has no damage to the car stereo, because the car stereo is mostly installed in the upper part of the dashboard, and the sunshade is better to avoid sunlight. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.

Figure 3 is a schematic diagram of the patent application trend of the third-tier technology branch in the field of internal and external decoration. The growth trend of patent applications related to seat technology and headlamp technology is more obvious. The seat is the first component to evaluate whether the car is comfortable or not. Headlights are also an important part of safe driving. From the overall trend, the number of patent applications for the above technologies has increased rapidly since 2005. There is also a growth trend in dashboards and center consoles, rearview mirrors and bumpers, with slower growth in patent applications compared with seat and headlight technology. The number of technical applications such as sunshade panel and interior panel, radiator grille and spoiler is less, and the application trend is relatively flat.

Facility vegetable production should do a good job in facility repair and heat preservation, adopt measures such as multi-layer film mulching and adding thermal insulation quilts to strengthen facility heat preservation, and where possible, heating equipment can be used to increase temperature. it is necessary to do a good job in the investigation of hidden risks in production, such as old facilities, heating charcoal and fire. Conscientiously implement measures such as clearing communication canals, timely uncovering and replenishing light, scientific fertilization and water pipe, etc., and make use of fine weather to restore ventilation and dehumidification in time after rain and snow, reduce the humidity of the shed, and reduce the occurrence of diseases. Vegetables in the open field should clear the ditch in advance to prevent stagnant water in the field, and cover the floating surface with covering materials such as plastic film, non-woven cloth or sunshade net to prevent cold; mature vegetables should be harvested and listed in time to ensure that the main vegetable products are not out of stock and not broken, so as to promote the stability of market prices.

Many car owners have already installed this car sunshade, easy to install and disassemble, it is easy to shrink and block the front windshield of the car, the heat and light of the vehicle can be kept out of the car all summer, and the license plate is so sweet.
