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.
This dress is suitable for relaxing occasions, such as outdoor picnics, travel and so on. It is recommended to choose a loose printed shirt, you can choose a short-sleeved T-shirt or loose shirt, with a pair of comfortable denim shorts or casual pants to increase the sense of leisure. You can choose a pair of light and comfortable sneakers or slippers to make the whole wear more comfortable. It is recommended to match a sunshade hat to protect against the sun and increase the bright spot of the whole dress. Hairstyle can choose natural long hair or tied into a ponytail to increase the whole casual sexy.
Fixed shading facilities cannot effectively block solar radiant heat in the morning and afternoon at low angles, especially on the east and west facades. Fixed vertical sunshades can provide some protection in this regard, but also reduce indoor illumination. Carefully arranged plants or mobile external shading facilities can also provide better control at lower solar altitude angles.
Greenhouse heat preservation should be done a good shading work, greenhouse heat preservation in the hot season greenhouse vegetable cultivation should adopt shading cover measures, commonly used shading equipment is sunshade, shading should be selected according to plant species. Short plants choose black shading net to choose gray shading in autumn and winter vegetable cultivation. Because the gray shading can prevent the growth of insects, if the seeds or film delay the cultivation of plants need to use the network. On August 7, when the weather is hot, it can be used in the sunshade net, which is relatively weak in the cold season, does not need lighting or no curtain, and does not shade in the heavy rain season. The heat preservation time of the net greenhouse is not long, and the plants are covered on the surface, especially the dark shade opens the daylighting. When growing mushroom crops, greenhouse heat preservation will not cause fungal crop infection, and the products can be recycled.
If the temperature rises in a straight line, you will prefer to wear a simple and comfortable match. The loose petal collar blouse is fresh and cool, and the A-shaped denim skirt is quite friendly to the pear-shaped figure, with small flat-soled white shoes. Hot summer sunscreen umbrella is indispensable, sunshade shape is not wrong, coupled with a bright lemon bag, a set of blue, pink and yellow macarons, daily commuting to the street.
Car windshield glass r780a8 glass sunshade Xiangyang car thermal insulation film can be divided into front and rear windshield film and side windshield film Among them, the front windshield has the highest requirement for thermal insulation film. According to the traffic safety regulations of the Ministry of Public Security, the light transmittance of the front windshield must be greater than 70%, on the premise that it does not affect driving safety.
Car umbrellas are useful. According to the sunscreen principle and the shape of the car, the car sunshade covers from the front windshield to the rear windshield. The sun umbrella which can effectively reduce the temperature rise in the car when parking at high temperature is called car sunshade.
The shading design should be based on the climate characteristics of the area, the use requirements of the room and the orientation of the window. The effect of sunshade facilities on shielding solar radiation heat not only depends on the shading form, but also depends on the structure, installation location, material and color of sunshade facilities. The shading device can be set to permanent or temporary. Permanent sunshade devices include setting various forms of sunshade panels in the window; temporary sunshade devices include lightweight curtains and various metal or plastic blinds in the window. Permanent shading facilities can be divided into two types: fixed and movable. The movable sunshade facility can adjust the angle of the sunshade according to the change of season, the time of day and the gloom of the sky. Shading measures can also use a variety of heat reflection glass and coated glass, sunlight control film, low emissivity film glass and so on.
4. generally speaking, indoor louvers can only block 17% of the solar radiation heat, while the horizontal sunshade with an outdoor south elevation of 45 degrees can easily cover 68% of the solar radiation heat, and the shading effect between the two is very different. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed will be distributed to the indoor air. If installed on the outside of the sunshade, most of the radiant heat absorbed will be distributed to the outdoor air, thus reducing the effect of indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings.
Loquat in open field can be covered with sunshade net, straw and other anti-freezing measures at low temperature at night. If part of the citrus is left on the tree, it should be harvested in time. If it is too late, you can pick the upper part and leave some of the lower part of the fruit. In these two days of freezing or frost, you can also cover some sunshade nets, ground cloth, straw and so on, to delay the heat preservation of oranges in the greenhouse.
