Greenhouse management: first, we should do a good job of anti-freezing. Freezable flowers can be equipped with an inner film in the greenhouse to form a two-layer film for heat preservation, and heating can also be carried out in the greenhouse if possible. Second, it is necessary to do a good job in strengthening the greenhouse. On snowy days, when there is snow in the greenhouse, we should remove the snow from the roof in time, increase the light transmission, prevent the greenhouse from being crushed by the snow, and reduce the freezing low temperature after the snow melts. When clearing the snow, you should avoid piercing the greenhouse film and transport the snow out of the nursery. The greenhouse with collapse and collapse deformation should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect.
If we choose a very ordinary item, when it feels nothing special, we can choose one or two exquisite accessories. For example, a seemingly ordinary black dress, adding a white headband, will feel much cuter and look good with age. White dress, pure and elegant, choose a straw sunshade hat and a chic straw bag, more pastoral style of fresh and natural, more youthful.
Under the scorching sun, the temperature inside the car will rise sharply to 50-60 ℃ or higher, so the damage to the dashboard and leather seats can be imagined. Therefore, for cars exposed to the sun, sunshades are a good choice, which can reflect sunlight, avoid exposure and have a certain effect on thermal insulation.
In the aspect of airbag miniaturization, it is mainly to provide more design space for the peripherals while meeting the lightweight requirements. The miniaturization of the steering wheel airbag improves the degree of freedom in the design of the steering wheel area and helps to improve the overall styling aesthetics of this area, such as the overhead front airbag. Compared with the traditional DAB (steering wheel airbag) and PAB (dashboard airbag) arrangement, the top airbag installs DAB and PAB modules on the roof sheet metal, liberating the steering wheel and front passenger instrument area, and providing space for smart driving, mobile interconnection and other equipment layout. Compared with the traditional front airbag, the top airbag is larger, the bag design is more complex, and the output of the generator is higher, so the airbag assembly is heavier. When arranging, it is necessary to consider the strength of matching with the body sheet metal, the NVH performance, the influence on the front upper visual field, the influence on the sunshade layout design and so on.
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. ”
Moreover, the hot weather will cause damage not only to the paint surface, but also to the car interior and dashboard. Therefore, car owners are advised to install sunshade curtains on their cars in summer. Has a very good thermal insulation effect, effectively isolate the sun, ultraviolet rays, but also can block the light and protect privacy.
In terms of temperature management, the early growth stage of spring cauliflower cultivation was in the low temperature season, and the growth was small, while the plant size of broccoli was closely related to the flower head yield, and the temperature increased rapidly in the later growth stage, which was disadvantageous to the flower bud differentiation and flower ball formation of broccoli. Therefore, in the field management, it is required to do a good job of heat preservation in the early stage of growth to prevent freezing. Those cultivated in greenhouse should be closed in time to keep warm, those cultivated in open field should be trenched and drained as soon as possible to prevent freezing, and the remedial method of covering the floating surface of sunshade net should be adopted in case of sudden frost or freezing weather. In the later stage of growth, after the temperature rises in April, the protected cultivation should do a good job of ventilation and cooling in time, and the flower heads should be harvested in time after maturity.
In May, take advantage of the holiday, choose a lawn with three or five friends, under the comfortable sunshade tent, you can put on a red and white plaid picnic mat and bamboo rattan snack basket, or you can sit at the online celebrity ins omelet table, eat barbecue, play vulgar wine table games, and come to Yunlan Bay to find the beautiful spring light missed this year in the sunshine, flowers, food and laughter.

The sunshade of the canopy is made of high impact resistance polycarbonate material, and its strength is about 200 times that of glass. Raw materials are imported from Germany and processed at home. The use of double-sided co-extrusion technology to add anti-ultraviolet materials can effectively shield more than 98% of ultraviolet rays, protect automobile top paint, and more effectively control continuous heating. At the same time, it also has flame retardant effect and can be used for more than 30 years in the environment of-30-60 ℃ (thermal deformation occurs at 137 ℃). The rain shed falling pipe is made of high-strength aluminum alloy with a unique and user-friendly design to avoid secondary pollution to you when the ceiling water falls to the ground. The utility model has the advantages of reasonable structure, easy cleaning and convenient removal of dirt in the pipeline.
McDonnell Douglas 001 is equipped with a suspended McDonnell Douglas 001LED display dashboard and a small solar panel on the front sunshade, which can power the dashboard and body lighting parts or batteries. This greatly improves the durability of the car.
