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 Qinghai photovoltaic greenhouse needs the cooperation of a variety of equipment, with higher and higher 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 Qinghai photovoltaic greenhouse project, please contact Minghao greenhouse Engineering Construction Company directly.
Take emergency measures for disaster prevention and reduction. Pay close attention to weather changes and timely do a good job in preventing extreme weather emergencies such as low temperature and frost damage and snow disasters. Before the strong cold air comes, the greenhouse facilities should be strengthened in time, the air leakage of the film should be repaired, and multi-layer covering should be used to keep warm at night. 0.2% potassium dihydrogen phosphate solution was sprayed on the leaves at low temperature for 1-2 times to enhance plant resistance. After strong cold air, the management of ventilation, light, humidity reduction, disease prevention and extra-root topdressing should be strengthened, watering should be strictly controlled, humidity in the greenhouse should be reduced, and plant growth should be restored as soon as possible. Plants are prone to water loss and wilting in fine weather. Sunshade nets or non-woven fabrics can be used to cover the sun, heat up slowly, gradually increase light, and prevent plants from withering and dying. Open-field vegetables can be tied up according to the situation, floating cover sunshade net, straw and other to prevent frost injury, rain and snow weather can rush to harvest some vegetables, stored in indoor batches on the market.
Conclusion: there are some less commonly used small functions on the car, such as the sunshade can block the rear car headlights and the seat belt seat can adjust the height, which are very practical functions. As long as you taste it carefully, there is indeed an inner smell on the car, and what other hidden functions do you know?
The May Day short holiday is coming, and I have found all the supplies for outdoor camping, such as spacious and sunshaded canopy, automatic rain-proof tent, hammock, online celebrity picnic mattress, inflatable bed, outdoor folding chair and so on.
Soft cashmere also decorates the central aisle, the interior of the door, the sunshade under the dashboard and the cabin dark green, black and laurel green leather contrasts sharply with laurel green micropipes, and charcoal gray cashmere is used in the cabin. Comfortable, soft and luxurious, it decorates the central aisle, the interior of the door, the lower part of the dashboard, the visor, the headrest and the upper rear of the seat.
