two。 Facilities are reinforced. First of all, we should do a good job in strengthening the greenhouse and other facilities to prevent the snow from crushing and collapsing the facilities. If the film is damaged, it should be repaired in time. When there is heavy snowfall, the snow on the facility should be removed in time to reduce the pressure on the facility, increase the light transmittance of the film, and reduce the freezing low temperature caused by melting snow. When removing snow, you should gently push it to avoid piercing the greenhouse film. The greenhouse that is crushed and deformed should be strengthened and repaired immediately. If it cannot be repaired, it should be covered with film, grass curtain or sunshade net in time to improve the heat preservation effect.
Do a good job in the production and supply of vegetables in winter and spring. 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 if possible, heating equipment can be used to increase temperature. completely eliminate the hidden dangers of production risks 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 and manage the soil moisture in advance to prevent stagnant water in the field; if possible, cover materials such as plastic film, non-woven cloth or sunshade net should be directly covered with floating surface 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 unbroken, so as to promote market price stability.
2. Improve the level of mechanized production and liberate the labor productivity. First of all, from the environmental control system of multi-span greenhouse, electric sunshade, electric film (window opening) ventilation, electric thermal insulation quilt, electric fan water curtain cooling have been realized, and the environmental control ability of greenhouse is more stable and reasonable. work efficiency is higher, do not need manual operation, just press the switch of the distribution cabinet. Looking at the agricultural production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic sprinkler irrigation, integrated water and fertilizer machine, automatic seeder, and even Internet of things control software are now very common systems. greatly improve the production efficiency and achieve precision irrigation and fertilization, water-saving and fertilizer-saving, soilless cultivation and other protection of soil from pollution.
Loquat in open field can be covered with sunshade net, straw and other anti-freezing measures at low temperature at night. If part of the citrus is left on the tree, it should be harvested in time. If it is too late, you can pick the upper part and leave some of the lower part of the fruit. In these two days of freezing or frost, you can also cover some sunshade nets, ground cloth, straw and so on, to delay the heat preservation of oranges in the greenhouse.
2) the intelligent sunshade control system uses the brightness sensor to control the sunshade motor. In the automatic mode, the sunshade system can automatically adjust the opening and rotation angle of the sunshade according to the exposure angle of the sun, the intensity of the light, the size of the wind, the quality of the weather and other factors to judge whether to close or not. The system protects buildings and their users from direct sunlight. Summer can block sunlight, block light, avoid excessive heat passing through windows and reduce indoor temperature; in winter, sunlight can be used to heat indoor, improve indoor thermal comfort, adjust the lighting demand of indoor space, and achieve the purpose of environmental protection and saving air-conditioning operation cost.
It is always inevitable to park cars outdoors in summer. In the scorching sun, the temperature inside the car will rise sharply to 50, 60 ℃ or more, such as the damage to the dashboard and leather seats can be imagined. At this time, a windshield can save the car from “cauterization”. Sunshade panel is a kind of sunscreen with reflective surface. When the vehicle is parked, the sunscreen placed at the front and rear windscreen can reflect sunlight, which can not only reduce heat into the car, but also avoid strong sunlight exposure to dashboards and console panels. When choosing and buying, it is best to choose a folded sunshade, which can be folded and stored when the weather turns cool, which is not only easy to carry, but also easy to save. two。
Do a good job in greenhouse reinforcement, heat preservation and warming. Such as using double film to cover cultivated mushrooms, press the outer plastic film to prevent air leakage. Check and reinforce the scaffolding to prevent heavy snow from collapsing. When necessary, measures such as removing the covering (such as the outer sunshade net) should be taken to reduce the pressure of the mushroom shed and reduce the loss.
The 13th Guangzhou sunshade door and window Exhibition, sponsored by Guangzhou Slogart Exhibition Planning Co., Ltd., will be solemnly opened in Guangzhou International Purchasing Center from July 8 to 10, 2023. With the theme of “Intelligent Technology, Green Building, Energy Saving and Environmental Protection”, this exhibition strives to create a building materials industry exhibition platform for domestic customers and traders. As the weather vane of the industry, this platform provides the best purchasing platform for dealers, real estate developers, engineers, even designers, decoration market, building materials market, door and window market, building materials supermarket and so on. It also provides enterprises with the best opportunity to show new products, expand the market, build channels and promote brands.
First, all kinds of accessories in the new car. The first category is the seat category. Including car seat cushion, seat backrest, seat cover and seat fabric, headrest and other materials; the second category is interior decoration. Including the car floor, door guard, side guard, rear guard, roof lining, curtains, floor cover, etc.; the third category is the functional category. Including car body insulation materials, anti-collision fillers, dashboards, sundries, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers, etc.
Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. 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. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
