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.
Comprehensively do a good job in cold prevention and warmth protection, ensure that the three-layer thermal insulation cover of the inner and outer shed film and grass curtain is in place, and on this basis, add an inner arch shed apron, and use the abandoned agricultural plastic film or idle sunshade net in stock to cover the grass curtain or non-woven fabric, press the edge, cover it tightly, and set up a two-layer film in the greenhouse if possible. Dangerous shed or damaged and collapsed shed can harvest the vegetables in the shed and store them indoors in advance so as to reduce the economic loss as much as possible.
When installing the rubber soft joint, the screw of the bolt should protrude the outside of the joint and tighten the bolts on the end face of each flange repeatedly and uniformly according to the method of diagonal pressure to prevent pressure deviation. Tighten the threaded joint evenly using a standard wrench. Do not use an afterburner to slide, slide or break the movable joint. In addition, it should be checked regularly to avoid loosening and causing the disc to fall off or seep. After the rubber soft joint is under pressure for the first time (such as installation, pressure testing) or before it is put back into use after long-term shutdown, it should be re-pressurized and tightened bolts before it can be put into use. When using or storing rubber flexible joints, high temperature, ozone, oil and acid-base environments should be avoided. Sunny outdoor or windward pipes should be set up sunshade. Sun, rain and wind erosion are strictly prohibited. It is forbidden to brush paint and wrap thermal insulation materials on the surface of rubber soft joints. Due to the aging of rubber products, it should be inspected and replaced in time. Return to Sohu to see more
Qinglong in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
(4) the door and window frame should be treated with anticorrosion on one side of the wall, and the filling materials for the gap between the frame and the wall are generally rock wool, mineral wool, expansive plastic strip, etc., whose main functions are heat preservation, cushioning, sealing and so on. (2) it is hot in summer in the west, because the hot air will still be heated in the evening, so sunshade and ventilation must be considered. The sunshine room in the west is of little use when there is less sunshine in winter. The northern location is suitable for a small office, with almost no light, but with good shadowless light, which can adjust the temperature or block the sun at the entrance. Light will increase the temperature of the sunshine room by 10 degrees in a short period of time, so you must consider its shape and settings.
