Irises should be watered enough after planting, and then should be watered reasonably according to the growth of irises in the future to avoid water shortage and drought in the soil. If it is planted in September, then the sunshade net will be used for about half a month. In October, the shading material should be removed step by step, not at one time, to avoid blind flowers caused by drastic changes in light. We should pay attention to the proper covering cloth every night to improve the heat preservation capacity of the soil. Do a good job of ventilation during the day to prevent the temperature from exceeding 25 degrees.
These parts are mainly produced by supporting manufacturers. Interior design includes dashboard, steering wheel, seat, seat belt, airbag, carpet, sidewall interior decoration, sunshade panel, handrail, car rearview mirror and so on. Exterior design includes front and rear bumper, glass, door anti-collision decoration strip, intake grille, luggage rack, skylight, rearview mirror, door structure and accessories and sealing strip.
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.
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.
As a new type of packaging material, plastic has been widely used in the field of packaging. For example, all kinds of hollow containers, injection molding containers, packaging films, woven bags, styrofoam straps, packing straps, etc. In terms of transport, the plastic used in vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle or per-vessel basis. Varieties include fuel tank bumper, sunshade seat, door handle, steering wheel, dashboard and so on The commonly used materials in agriculture are film, pipe, plate, rope, woven bag and so on. Plastic granule manufacturers introduce the packaging for plastic greenhouse, crop fertilizer and so on, plastic pipes for farmland and water conservancy projects, farmhouse construction, animal husbandry protection, agricultural machinery and utensils, fishing net culture, floating, etc.
Temporary shading of rural domestic sewage treatment equipment is the installation of lightweight curtains, plastic blinds or pendants at the window, while sexual shading is the installation of sunshades in various forms in the window. The facilities of sexual sunshade system can be divided into active form and fixed form according to whether the components can be disassembled and moved. In recent years, the active sunshade system is widely used in buildings in our country, and the angle of the sunshade can be adjusted freely according to the annual seasonal change or the all-day sunshine change. Because of the strong flexibility of this facility, it can also be easily removed in order to get sunshine and avoid blocking the sun in the cold season. Today, with the rapid development of science and technology, there are all kinds of heat reflection glass, such as sunlight control film, coated glass, low emissivity film glass and so on.
The main contents are as follows: 1) the structural design of the window should be reasonable. In the design of the building window, it should not only reflect the control effect of the window on sunlight, but also limit the volume ratio of the window to the wall. If the window area of the building is relatively large, endothermic glass or heat reflection glass can be used, and other shading measures such as balconies, curtains and sunshades can also be taken. If the outdoor temperature is low, natural air can be used as a direct source of energy. Therefore, when designing the construction of the window, you can set a natural pass on it that can open the shoulder;
3. Use a sunshade. Sunshades are like umbrellas for cars, which can block the sun and prevent ultraviolet rays. It can play a good role in protecting the items in the car, such as navigators. When parking, put the front and rear and left and right sides of the car on the sunscreen, which can reduce the thermal effect of solar radiation on the temperature in the car.
Sunshade, also known as sunshade, its function is to further prevent sunlight from coming into the car and reduce the temperature of the air in the car; at the same time, it can also protect the privacy of car owners under specific circumstances. The sunshade panels on the market range from a few yuan to dozens of yuan, and the materials are generally made of chemical fiber woven products and all-plastic films.
6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus playing the role of energy saving and consumption reduction. 5. Heat preservation and heat relief: electric curtains can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
