The energy consumption is slightly higher. Therefore, the multi-span greenhouse in the northern region needs to do a good job of heat preservation. Carry out R & D and design in thermal insulation. How to build a three-span greenhouse before determining the use of the multi-span greenhouse for the project, we should first consider the orientation of our region, the climate characteristics, the use of the glass greenhouse. For example, in the glass greenhouse for planting and seedling raising in the northern region, the important work is to maximize the thermal insulation performance of the greenhouse under load. We can add an internal thermal insulation system on the top floor of the greenhouse. The glass around the greenhouse should use double-layer hollow glass as much as possible, and for example, to build a glass greenhouse in the northwest, such as electric sunshade system, electric ventilation system and so on. By adding terminal equipment of the Internet of things, this kind of multi-span greenhouse can automatically start and stop the greenhouse equipment by issuing data acquisition and analysis instructions.
To maintain the battery, be sure to bury the battery deep under the protection. Other parts of the vehicle include some air conditioners, lamps, etc., do not directly maintain the vehicle in accordance with the requirements, should rotate the air conditioner (such as light bulbs) and rotate the air conditioner clockwise several degrees. Open the sunshade of the car body in summer, then separate the air conditioner from high and low, and then drive the car to the lower position, two laps, two laps up, in the design of the branches to find the place of ventilation, the electric warm wind can be determined. The maintenance time of each part of the new car in all directions is 15 minutes, which can quickly find out the good effect in a short time. The process of each maintenance is: every delivery inspection, to the highway, any automatic car driver must master the vehicle maintenance knowledge, must not blindly reduce fuel consumption.
The interior design of the vehicle has changed from the previous generation family design of the old Mercedes-Benz GLE, using an integral sunshade to integrate the dashboard and the liquid crystal display on the central console. The dimensions of both LCD monitors are 12.3in. In addition, users can also choose to install HUD head-up displays. Under the concept of vitrified cockpit, the function of the center console has been completely weakened. Compared with the new generation of Mercedes-Benz E-class design, the new generation of Mercedes-Benz GLE integral sunshade design will feel better, and as the central air outlet between the upper and lower parts of the dashboard, it also uses four rectangular structures. After the elevation of the height and width of the sub-dashboard, the encapsulation has also been fully strengthened.
1. Do a good job of cold resistance and anti-freezing measures. For Fritillaria thunbergii, Yuanhu, saffron and other traditional Chinese medicine, can cover straw, sunshade net and other anti-freezing. Control the water content of Dendrobium candidum matrix, seal the greenhouse film, prevent cold air from entering the greenhouse, and multi-layer covering can be used in the greenhouse. For breeding seedlings, potted flowers and some Lunar New year Flowers and precious flowers, it is necessary to do a good job of heat preservation in the shed, and lilies and Lunar New year flowers need to strengthen heating measures, especially when low temperature comes, pay attention to watch at night and heat up continuously to prevent frost damage caused by sudden changes in temperature in the shed. For the gerbera produced in the simple greenhouse, when the low temperature freezing comes, the film needs to be added to resist the low temperature, and a layer of non-woven cloth can be added in the greenhouse to enhance the thermal insulation performance.
The standard lighting of the cab of the new BMW3 series sedan is entirely composed of LED. This includes front and rear reading and interior lighting, as well as glove box lighting, lockers under the central armrest, foot space, sunshades and rearview mirrors and doors in suitcases. Optional ambient lighting can provide atmospheric light for the cabin and can also be adjusted as needed. Additional indirect lighting along the contours of the dashboard and door panel uses precisely positioned LED fiber optic light guides to create a dynamic, unique atmosphere. There are six light colors and eleven luminance combinations,
Employers can also perform a series of tasks remotely throughout the building. These tasks range from locks that automatically protect employees and construction workers, to operating sunshades to introduce sunlight during the day and close them at sunset, to occupancy monitoring, and receive real-time reports from employees on building problems in need of repair, and more. Employers can solve maintenance and a range of problems without placing employees. By accessing all data from one dashboard, they can comprehensively manage occupancy and space utilization in real time, and plan space optimization and leasing.
The optimum temperature for strawberry seedling growth was 25 ℃ ~ 30 ℃, and the stolon stopped growing when it exceeded 32 ℃. Therefore, in the early stage, the greenhouse should do a good job of heat preservation, improve the air temperature and substrate temperature, and promote the early emergence of stolons. In the southern region, the temperature from mid-May to early July is suitable for the occurrence of stolons, during which the number of stolons is large and the interval between stolons is short. From mid-July to August, with high light intensity and high temperature, the greenhouse should be covered with a sunshade net with a shading rate of 60% from 9 am to 5 pm every day, so as to reduce the temperature and ensure the normal growth of mother and offspring. In addition, moderate shading in the later stage of seedling cultivation can meet the low temperature and short day conditions needed for strawberry flower bud differentiation and promote strawberry flower bud differentiation.
