To increase the work efficiency, fourth, the greenhouse support is produced by machinery. Great production efficiency, low requirements for the quality of workers, employing 3-5 people, single machine daily production of rice. Fifth, the greenhouse accessories skeleton machine can produce hollow and solid products. And the height, span, Radian and diameter of the skeleton can be arbitrarily adjusted to produce round, oval and rectangular skeletons. How to adjust the construction temperature of vegetable greenhouse, the main measures to control the temperature of vegetable greenhouse are heat preservation, humidification and ventilation, for example, in winter. For temperature, insulation will be covered outside the hut to meet crop growth needs, and ventilated diseases will keep warm during the hot summer. 1. The roof is covered with sunshades, usually with sunshade and grass curtains. The roof is covered with two layers of sunshade nets, the inner layer is close to the plastic film, and the outer layer is about 15 to 20 centimeters from the top of the roof.

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.

Car interior parts include dashboard, door inner panel, steering wheel, seat, roof, floor mat, sunshade and so on. The surface of the interior decoration should be smooth, wear-resistant, heat-resistant, low-reflective, sound-absorbing and masking, and it is not easy to volatilize toxic gases in direct sunlight. At present, the amount of plastic used in automobile interior parts has accounted for more than 50% of the plastic consumption of the whole vehicle. PP is used as the main raw material to make a new type of automobile dashboard, which not only has good comprehensive properties such as toughness, strength and appearance, but also reduces the automobile cost, so it is widely used on the automobile dashboard. Nearly half of the materials made by European companies for automotive dashboards use PP, and this trend will continue to grow.

The smell in the car, the material is the source. An in-car air management team is looking for alternatives to environmentally friendly materials for parts, such as ceilings, dashboards, door panels, sunshades, carpets, seats, interior plastics, seals, wiring harnesses, etc. Typical material schemes are as follows:

two。 The shuttle-shaped sunshade is disassembled under the glass roof of the sunshine room (that is, indoor installation). In addition to effective shading, it is also compressing and isolating the indoor space after the blade is closed, improving the energy consumption of indoor air conditioning and effective thermal insulation; other disassembly is turning the blade angle at the top of the glass to play a different whitewashing effect, especially under the lighting to create a more brilliant sense of color and organization. The heat and moisture exchange between the exhaust air of the air conditioned room and the fresh air is carried out through the full heat exchanger, and the waste heat recovery of the air conditioning system can be realized by using the cooling and dehumidification of the exhaust air of the air conditioned room.

When it is also hot, the way to build a sunshade or sunshade net over the whale can be effective in direct sunlight. To achieve the purpose of cooling, apply reflective radiation paint three times. For the original state of Whale Island Paradise, Shanghai Enyu Media does not recommend applying reflective paint directly to the shell of Whale Island. It can be used on the sunshade, and then perpendicular to the light. Play the role of outward refraction. To achieve the purpose of cooling, recruit four convection ventilation. Enyu Media Whale Island maintains the original intention of the design. A three-door design is used to design a pedestrian door on the head of the whale. Emergency doors are designed on both sides, which not only deal with emergencies, but also play the role of ventilation and air convection. Reduce the indoor temperature, recruit five surrounding green plants, one of the functions of green plants is to filter and precipitate impurities in the air, absorb carbon dioxide and exhale oxygen.

Another growth factor related to humidity is light. Blueberries are not particularly strong for it, but moderate light is needed to ensure growth. Generally speaking, a sunshade net should be used to isolate part of the exposure when the sun is strong, so as to ensure that the temperature in the blueberry shed should not be higher than 26 degrees. Especially when the summer temperature is particularly high, you can cover two layers of sunshade net on the surface, otherwise the high temperature will make blueberries stop growing. The sunshade net can be removed when the temperature drops in the evening, and if the temperature is too low, the thermal insulation film on both sides of the shed needs to be put down to increase the temperature in the shed. But leave some holes in the perimeter to strengthen an internal air flow. When the weather is bad, one should pay attention to the heat preservation work, and the other is the drainage work.

Now the weather is getting hotter and hotter, many people would rather stay at home and not go out, and for some people who drive to work, it is really a very painful thing. Every time the car door is opened, it is like a sauna. So when car owners park, they will choose to take the sunshade out to block the sun to avoid the excessive temperature in the car, so is the sunshade really useful? Come and have a look with the editor.

●?? 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.
