2. Planting and management of eggplant fruit vegetables in spring and summer in protected areas. Tomato, eggplant, pepper and other eggplant fruit vegetables have been planted in the protected areas in spring and summer. The following aspects of work should be carried out in time: first, the protective facilities should be built and the greenhouse film should be buckled 15 days before planting, and the old shed should be overhauled in time. Second, fine soil preparation, deep ditches and high beds, especially around the shed to open ditches to lower the groundwater level. The third is to fully apply high-quality and mature base fertilizer. Fourth, after planting, timely watering root water, covering plastic film, building a small arch shed, stuffy shed for 5-7 days to promote slow seedling. Fifth, according to the weather changes and plant growth, timely ventilation and exhaust harmful gases during the day, and the low temperature at night should cover the small arch shed with grass curtains, sunshade nets, non-woven fabrics and other mulch to keep warm.
The turn of the stars of “in the other way, but also the other body” is the last school of the Murong family in Gusu. Car sunshade is a typical representative of this kind of martial arts, it can reflect heat to achieve the purpose of cooling. Place a sunscreen at the front windshield to prevent direct sunlight from raising the temperature in the car. It is understood that sunshades of better quality can reflect more than 70% of the heat.
At present, the open field vegetables grown in the field are kale, green vegetables, snow vegetables, mustard, cauliflower, broad beans, peas, celery, heading cabbage, yellow sprouts, carrots, onions and garlic. First, in terms of management, we should do a good job in shallow ploughing, soil cultivation, weeding, topdressing, and timely drainage after rain. Second, cauliflower, Chinese cabbage, yellow sprouts, carrots, onions and garlic can be harvested and listed in batches in time, while doing a good job of anti-freezing and heat preservation, covering the floating surface or small arch shed with straw, greenhouse film, sunshade net or non-woven cloth at night when the temperature is low, and rice straw bundles are used for heading Chinese cabbage to ensure the compactness of the ball and avoid frostbite.
Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
It is recommended that the length of the extension should not exceed 5 meters. Among all the sunshade products, the canopy is a good partner for the sunroom. Outside sunshade electric double-track ceiling curtain: electric double-rail folding ceiling curtain is a sunshade system that can be retracted and put on the top or oblique side glass window frame of indoor lighting roof, that is, double-rail translation system. If the daylighting of the balcony at home is on the middle side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match.
Glass curtain wall: the curtain wall of the main terminal is in the form of a 18-meter unit, which is divided into 3 small units, two self-supporting columns of the curtain wall, which are placed on the inside of the curtain wall, each column is built-in stainless steel downcomer, the first main column is covered with stone, and the indoor and outdoor ceiling runs through to the outside of the curtain wall; the finger corridor still takes 9 meters as the unit system, and the square column is used for thermal insulation and waterproofing, and the downwater pipe is placed in front and wrapped in stone. The horizontal sunshade is 9 meters long to bear the horizontal wind load, and the gravity load is suspended by stainless steel poles in each vertical seam of glass. The roof boat-shaped large daylighting roof adopts the scale of 1.5X3 meters per piece of glass, and the rest of the strip or distance daylighting roof glass uses a single piece of 1.5X1.5 meter safety scale. The aluminum plate rain canopy is arranged above the curtain wall on both sides of the corridor, and the appropriate lap length is set at the connection part of the corridor to ensure the integrity of the appearance.
The so-called “bright window action”, as the name implies, is the car window bright action. According to the relevant regulations, all car windows are not allowed to carry sunshade films with reflective properties, and the transmittance of ordinary refractive protective films should be more than 50%, that is, the transparency of window glass needs to be more than 50%. The film transmittance of the front windshield and exterior rearview mirror glass of all cars should be higher than 70%.
As for the temperature inside the car, the Japanese Automotive Union JAF has also done relevant tests before, and found that the same car was found to be black and white respectively, and exposed to the sun for four hours with closed windows and no sunshade curtains, sampling temperature changes in the room, above the dashboard and on the roof respectively.
Whether you are in a car or other fixed pickup at close range, 4097CORE? The miniature gun microphone is a useful and unique solution. With compact shape and clear audio pick-up, the microphone can be quickly installed in a small space (such as squeezed on the sunshade of a car, sandwiched on the dashboard or placed under the table)
Double-layer glass can achieve the same area in terms of heat preservation and thermal insulation, the temperature of the building is uniform and asymmetrical, and there is no problem with the thermal insulation performance of all-glass. The outdoor frame of the solar roof works under all-glass sunshade, so it is divided into electric glass and machine glass to prevent rain leakage in rainy days.
