One acre of greenhouse price cost-greenhouse cost

　　 one acre greenhouse price construction, greenhouse construction

　　The cost of greenhouse per meter can be reduced or reduced. Among them, the cost of brick walls is about 800 yuan per meter, and the use of concrete foam bricks can reduce the cost of greenhouse by 100-150 yuan per meter. Advantages: the brick wall structure is sturdy and durable, and the service life can reach 20——25 years; the brick wall solar greenhouse has high land utilization rate and strong regional applicability, especially suitable for complex geology, low water level, and unable to build earth walls The area is used for construction. Disadvantages: Due to the brick wall structure, the cost of the greenhouse is higher than that of the earth-wall solar greenhouse, and the investment return period is longer. In the use of greenhouse, there are still problems of low utilization rate and low economic benefits. In the current use of plastic greenhouse, attention should be paid to the reasonable arrangement of stubbles, so that the greenhouse can fully function and achieve the purpose of increasing income. 1) The type of crop that is mainly based on our training. The greenhouse consists of three crops including dry-cooking cultivation in spring (peppers, tomatoes, cucumbers, green beans, etc.), delayed cultivation in autumn (peppers, tomatoes, etc.) and seedling cultivation in winter (solanaceous fruits, melons, beans). , One is surrounded by double-layer hollow glass and the top is a double-layer hollow pc board (sun panel), the other is surrounded by double-layer hollow glass, and the top is covered with single-layer tempered glass. The two are the same in appearance and style, but the difference is the performance of the covering material. In the cast iron and ductile iron markets, mainstream regions such as Shandong and Shanxi, as the temperature gradually decreases, downstream operations are not high, market demand is weak, iron factories have large inventories, and manufacturers are difficult at the end of the year, price reductions are strong, and merchants are more pessimistic , The short-term market price will remain stable and weak, with a range of 30-50 yuan/ton. Taken together, at present, domestic price fundamentals are still sluggish, the downstream terminal demand seasonally weakens, iron ore and other raw material cost support is weak, the financial pressure in the industry remains unabated, and the subsequent market price rebound may be indefinite. However, the country’s policies for stabilizing growth are being strengthened, and the production and sales of new energy vehicles have also increased, which is also conducive to improving the current contradiction between supply and demand in the market. Years ago, the mid-market price may continue to stabilize and consolidate, but a substantial rebound is no longer possible. may. The new normal of the steel industry can be summarized as: the simultaneous low-speed growth of steel supply and demand. It should be tightened and installed in time. The state of the greenhouse is related to the growth and harvest of internal plants, so maintenance work is required. The greenhouse is always in a high temperature and high humidity environment, and an important factor affecting the life of the greenhouse is the corrosion ability.

　　 Spring begins in late February. After planting solanaceous fruit and melon seedlings, small arches should be used to cover the grass fence for insulation, and they will be available in mid-to-late April. Delayed cultivation of tomatoes and peppers in autumn can prevent freezing and heat preservation in the later period, which can be postponed to the market on New Year's Day. The winter seedlings are mainly tomato, pepper, eggplant seedlings (3-4 true leaves) in the shed with multiple layers of cover, and the last crop of vegetables should end in mid-November. The above arrangement is based on early maturity in spring, and the purchase of fertilizers must be sufficient, and the cultivation technology must be high in order to achieve the desired purpose. The cropping type is based on nursery. bklfjvkbed Jiangsu Hennong Greenhouse Tube Co., Ltd. reduces the temperature in the greenhouse and plays a certain role in protecting the plants in the greenhouse. The above is all the content introduced for you, I hope it will be helpful to you. If you want to learn more, you can browse our website and we will provide you with more professional information. Greenhouses are very important for agricultural production. Our common greenhouse include pc board greenhouse and traditional plastic film greenhouse. Then the pc board greenhouse are compared with plastic film greenhouse. First of all. We can compare the two materials. The pc board greenhouse uses pc board. Not only the appearance is relatively more beautiful, and the service life is longer, but the plastic film needs to be replaced every two years by the user. It can be seen that the pc board is more time-saving and labor-saving. Secondly, saving resources is what we are now advocating. We can compare the two in terms of energy saving. The thermal conductivity (K value) of plastic film is much higher than that of pc board, so it is easier to lose heat. Then compare the impact resistance of the two. It is obvious which of the two has the better impact resistance, a kind of pc board & mdash; sunshine board. Maybe drip irrigation. No matter what method is adopted, keep a distance of 10 cm from the plants, and avoid the fertilizer directly touch the plant stalks and burn the seedlings. Especially peppers, flue-cured tobacco, melons and vegetable crops. High temperature climate above 35℃ at noon.

　　 consists of seedlings in winter, seed production in spring, and orchid stubble cultivated in autumn. The nursery starts in December, and there is an electric hotbed in the shed for direct seeding. The seedlings bred in the hotbed can also be planted in the cupboard, and small arch yokes and grass fences should be used for heat preservation during the winter. After the seedlings are bred in spring, they are planted with the fathers for pepper or tomato seed production, and the female parents for car consignment (or the original seeds of various parents can also be propagated) for hybrid seed production. Just master the seed production technology. , Multi-span greenhouse should also pay attention to the insulation function. Improving the thermal insulation function of the greenhouse and reducing energy consumption are direct means to increase the efficiency of greenhouse production. The thermal insulation ratio of the multi-span greenhouse is an important indicator of the intention to measure the thermal insulation function of the greenhouse. The larger the thermal insulation ratio, the better the thermal insulation function of the greenhouse. The durability of the multi-span greenhouse needs to be considered, because the multi-span greenhouse operates in a high temperature and high humidity environment for a long time, and the anti-corrosion of the construction surface is also one of the important factors affecting the service life of the multi-span greenhouse. There are three types of materials for covering the multi-span greenhouse: laminated glass, sunlight board and plastic film. At this stage, it is widely used in agricultural planting, and the project has a long investment life. Even if the greenhouse looks simple, there are standards. After the greenhouse adjustment, the construction unit needs to transfer the technology to the customer, and do a good job of learning and training the operation methods of machinery and equipment. Such as the common problems of shading system software power switch, reducer maintenance, regular maintenance of power distribution system, etc. The multi-span greenhouse is operated by the control staff, and other irrelevant staff are strictly prohibited to operate. Check the limit switch of the shading system once a month to check whether there is any noise during the rack drive system. First, an analog combination instrument is used to collect on-site information and carry out instructions, recording and control. A distributed control system appeared in the late 1980s. The multi-factor integrated control system of the computer data acquisition control system is currently being developed and developed.
