3. Sowing, seedling and transplanting of fruits and vegetables should be done in time. Sowing seedlings or transplanting seedlings at noon in sunny days should be used in time to improve the strong seedling rate and survival rate. In the near future, it is necessary to do a good job in sowing and raising seedlings of melons in the greenhouse, laying electric heating lines to raise seedlings, covering the inner film early and late in sunny weather, revealing the film at noon in cloudy and rainy weather, covering the sunshade net or non-woven cloth on the small arch shed at night, artificial lighting and warming should be carried out in case of continuous low temperature and overcast and rainy weather to cultivate strong seedlings.
User comments: I like this bag so much, and my mother also likes it very much, so I simply bought an identical one for my mother. ? The bag looks small, but in fact, it can hold things, thermos cup, sunshade, handkerchief, paper, keys, cell phone, no problem.
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,
2. It is necessary to make full use of all kinds of facilities to create favorable conditions for crop growth and anti-freezing. For example, the greenhouse should do a good job of heat preservation and temperature increase in the greenhouse to ensure immortal seedlings; it is necessary to actively prepare sufficient materials such as film, sunshade net, rice straw and so on. In case of freezing weather, do a good job in covering, especially cash crop seedlings; and remove the mulch in time after snow and ice to reduce freezing damage, prevent snow from freezing and crush the greenhouse, and reduce losses.
There is no bulge on the surface of various devices in the car cockpit, the material is soft and elastic, and the sharp corners, protruding edges and protruding parts can be reduced as much as possible, which can reduce the injury suffered by the passengers in the event of collision. The range of interior softening includes prominent accessories such as steering wheel, dashboard, side circumference, roof, seat, floor and sunshade. The steering wheel of some cars can contract during a collision, and some seats have headrest to prevent head injury when the rear is hit. These are all designs that can improve the safety of the car.
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, which can reduce the burning inside the car to a certain extent, and prevent leather seats and dashboards from being damaged by ultraviolet rays.
Use or store rubber soft joints, should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. It is very important to choose a suitable rubber joint, if you do not choose the right rubber soft joint to work, then the service life of the rubber soft joint will be greatly reduced due to the influence of the external environment and internal medium. not only a waste of resources, but also may lead to heavy damage to the whole pipeline or even have to be rebuilt, then the loss outweighs the gain.

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 Qinghai photovoltaic greenhouse needs the cooperation of a variety of equipment, with higher and higher 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.
