In the severe winter weather, the small arch shed in the greenhouse should be covered with a layer of straw buns or covered with quilts to keep warm, and then covered with a layer of film. Add windbreak and anti-freezing barrier. The combination of straw and old film into a cold wall, placed in the north of the vegetable greenhouse, as a wind barrier, can reduce the harm of cold current. When the temperature in the greenhouse is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. When heating, open fire can not be used to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside. Focus on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings that are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent frost damage or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed to make the plants see as much light as possible.
In the intelligent greenhouse, the single-family greenhouse can use the Internet of things technology to become a measurement and control area of the sensor network, using different sensor nodes and nodes with simple actuators, such as fan low-voltage motor valves and other actuators with low working current, to form a network to measure matrix humidity, pH temperature, air humidity, air pressure, light intensity, carbon dioxide concentration, etc., and then through model analysis Automatic regulation of greenhouse control of irrigation and fertilization operations, resulting in plant growth conditions. Intelligent greenhouse, also known as automatic greenhouse, refers to automatic facilities such as computer-controlled movable skylight sunshade system, heat preservation system, wet curtain / fan cooling system, spray drip irrigation system or drip irrigation system moving seedbed, high-tech “intelligent” greenhouse based on agricultural greenhouse.
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 Guangdong solar panel greenhouse needs the cooperation of a variety of equipment, with the increasing 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 how much the Guangdong sunboard greenhouse is, please contact Minghao greenhouse Engineering and Construction Company directly.
The structural design of frame cover fan is adopted to ensure the tightness and waterproof between frame fans, as well as to fully show the permeability of doors and windows on the basis of high safety factor and strong wind pressure resistance of the products, so that the field of vision is more open and the household space can be extended. Under the premise of design requirements, adding external sunshade, awning and appropriately increasing the length of 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, a
In terms of interior decoration, domestic head enterprises are almost “monopolized” by the Yangtze River Delta. Ningbo Jifeng shares, Huaxiang, Topu Group, Shanghai Yanfeng Automobile, Daimei shares, Jiangsu Xinquan shares and Changshu Auto Decoration cover the one-stop industrial chain from seats, sunshades, dashboards to the entire internal and external decoration system.
Why use sunshade? The main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. Among them, there are many different types of products. Second, in terms of service life, the steel drag chain is generally no less than 10,000 times, which is also a variety of technical advantages that can really be brought about by such a rotation speed. after updating such characteristics, we will be able to constantly grasp such technical characteristics, and then form the key to be more convenient to use in machinery. In order to fully grasp such technical advantages, this is * the main reference. After the continuous improvement of service life, gradually will be in this point of view, or more important, to be able to grasp such a technical advantage, is * the key.
This bag is much better than I thought! Surprise ~ it feels so comfortable! The quality is very good, the design of the fold is very good. Capacity than imagined can be installed, put sunshade small water cup completely pressure-free ~ super good-looking Ness
