One of the simplest items in the high temperature test is the exposure test, in which the vehicle is parked in the hot sun with the front facing west, and the temperature display patch is affixed to the critical parts of the vehicle, such as engine cover, dashboard, deflector, and so on, and the temperature in the car is as high as 70 or 80 degrees. Then test the door handle, dashboard, sunshade, air conditioning outlet and other internal and external accessories for abnormal sound or efficacy failure.

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.

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.

Especially in some high-end cars and concept cars, natural hemp fiber composites have been used instead of chemical fiber composites such as glass fiber and other chemical fiber composites, such as car interior door panels, miscellaneous boxes, truck floor, spare tire cover, seat backrest, dashboard, seat armrest, roof interior decoration, sunshade panel, luggage compartment decoration board and so on.

There is nothing wrong with all practical designs on the new flying dashboard-the entire dashboard is made up of straight lines, including the details of the dashboard sunshade. All aggressive features that may affect the internal sense of space are invisible in terms of brand-new flying.

Two days ago, Sun Li also posted a photo of her sister modeling another handbag made by her mother. In the photo, many girls wear sunglasses and sunshade hats, a white shirt dress and a bag made by their mother, dressed in a fresh and stylish literary style.

Before determining the use of the multi-span greenhouse for the project, we should first consider the location of our region, the environmental and climatic characteristics, and the use of the glass greenhouse. For example, in the glass greenhouse for planting and seedling raising in the northern region, the most important work is to improve the thermal insulation performance of the greenhouse as much as possible under the load. We can add an internal thermal insulation system on the top floor of the greenhouse. The glass around the greenhouse should use double-layer hollow glass as much as possible. For example, to build a glass greenhouse in the northwest, we can add Rain Water collection system, external sunshade system and so on. At the same time, planting greenhouse is different from ecological restaurant and leisure tourism agriculture in that the height of planting greenhouse can be 4 meters to 6 meters, and the shoulder height of leisure and sightseeing greenhouse is generally 5 meters to 6 meters.

In the intelligent greenhouse, the single-family greenhouse can use the Internet of things technology to become a measurement and control area of the sensor network, using different sensor nodes and nodes with simple actuators, such as fan low-voltage motor valves and other actuators with low working current, to form a network to measure matrix humidity, pH temperature, air humidity, air pressure, light intensity, carbon dioxide concentration, etc., and then through model analysis Automatic regulation of greenhouse control of irrigation and fertilization operations, resulting in plant growth conditions. Intelligent greenhouse, also known as automatic greenhouse, refers to automatic facilities such as computer-controlled movable skylight sunshade system, heat preservation system, wet curtain / fan cooling system, spray drip irrigation system or drip irrigation system moving seedbed, high-tech “intelligent” greenhouse based on agricultural greenhouse.
