1. What is the Shading net

Shading net, also known as Shading net,Shading net, cold yarn, cool yarn and so onIt is a special protection coverage material such as agricultural, fishing, animal husbandry, windproof, and soil that has been promoted for more than 10 years.The shade net uses polyethylene (HDPE), high -density polyethylene, PE, PB, PVC, recycling materials, new materials, polyetteth ethyl, etc., which are treated with ultraviolet stabilizers and anti -oxidation treatment.The characteristics of aging, corrosion resistance, radiation resistance, lightweight, etc. are mainly used for the protection of vegetables, fragrant aunts, flowers, edible fungi, seedlings, medicinal materials, ginseng, ganoderma, and aquatic poultry breeding.Obvious effect.

2. The role of Shading net

The Shading net is mainly used in summer, especially in the southern promotion area.The use of Shading nets in the south in summer has become a major technical measure for disaster prevention protection.In summer (June -August), the main role of covering the shade net is to prevent the irradiation of scorching sun, the impact of rains, the harm of high temperature, and the spread of pest pests, especially for preventing insect pests from migrating.After covering the shade net in winter and spring, it also has a certain heat and humidity effect.

Third, the Shading principle of Shading net

Sunshine is spread straight, encounteredShading netAfter that, the Shading net will reflect part of the sunlight, because it has the effect of absorbing ultraviolet rays, and some of the heat will be absorbed. Because black is best in absorbing calories, the Shading net is generally black.If it is used for Shading and cooling of the courtyard, it can generally use other colors for beauty, such as green, the difference in Shading effect is not obvious, but the environmental beautification effect has improved a lot.The Shading net is densely distributed, which can keep the air flow in order to ventilate and dissipate heat.

1. How to build a Shading net

There are two types of coverage methods covering and gazebo. In practical applications, gahaocated coverage is better due to the Smooth cooling effect of air circulation, and it is used more.The specific method is to make a skeleton with wood or iron first, and then use the skeleton of the arch shed to cover the shade net at the top, leaving 60-80 cm of ventilation bands on the top.If a film is covered, the shade net cannot be directly covered on the film, and there should be a gap of more than 20 cm to use the wind to cool down.

2. How to fix the shade net is not afraid of the wind

If you want to stabilize the Shading net, the method is actually very simple. When building, you need to bundle it in every corner of the installation with the wire, and then fix the shade net to the wire.Pay attention when building, do not only fix the two sides, the middle position also needs to be fixed, and it must be fixed and strong.

Pay attention to the time to build a Shading net. It should be adjusted in a timely manner according to the weather changes.It should be avoided all day covers. It can be covered according to the temperature at 10 am to 4pm. When the temperature drops to 30 C, the shade net can be removed. Do not cover it on a cloudy day.The adverse effects.

Plant crops need to cover different stages in different growth stages. For example, after the first seeding is covered, it is to ensure the humidity of the soil and not being pecked by birds. At this time, the shade net is generally covered directly on the ground.

During the use, good air circulation is needed. Although the shade net can reduce the temperature and block the strong light, if it affects ventilation, it will have a great impact on the growth of plants and crops.

1. A few shots of Shading nets are best

For the greenhouses that plant vegetables, not only should it be clever in summer, but also shade and cover the shade net.The shade net is divided into two, three stitches, four stitches, six needles and other species according to the fine degree of density or light transmission.The Shading net is too sparse, the Shading rate is not high, and the cooling effect is poor.The Shading net is too dense, the light is too small, and the vegetables are easy to grow.

After a summer practice, the greenhouse Shading net generally uses a three -needle Shading net, and two -needle Shading nets can also be used.Essence

At the same time, when the temperature is high in summer, the cooling effect can be enhanced by covering two layers of sunshade nets. The first layer is fixed, relatively sparse, and can be used with two stitches.The other layer is activity. You can use three stitches to open it when you need it, and put it away when you do not need it.Generally, the temperature of the temperature will be on the event at 10 am to 11 am, and the Shading net on the activity will be opened. When the temperature starts from 3 to 4 pm, it will be put away when the temperature starts to steadily decrease. This can control the temperature to a certain extent.Not long.

Second, the more the number of ungathetic net needles, the better, the better

Seeping a few stitches represent the number of pins in each inch. The more the number of pins represents the dense the eye, the better the Shading effect, but the too large number of needles will also cause the shade net to be too heavy, which is not conducive to ventilation and ventilation.Therefore, the number of needles for the choice of Shading nets needs to be determined according to the actual usage and needs.To achieve a good Shading effect, it will not affect the circulation of indoor air.

The main function of the Shading net is to block the sun and prevent plants from being sunburned or sunburned.If you want plants to better photosynthesis, you can choose a low -number of pins (such as 3 stitches or 4 stitches) may be more suitable.If you want to sunscreen better, you can choose a high -number of pins (such as 6 or 8 stitches).

1. What types of Shading nets

1. Round silk Shading net

Because the Shading net is woven by the meridians and weft lines, it is mainly woven by the editorial machine. Therefore, if the meridians and weft lines are woven by round silk, it is the silk Shading net.

2. Flat silk Shading net

Both the meridian and weft lines are flat -filaments woven.

3. Round flat silk Shading net

The meridian is flat wire, the weft line is round wire, or the meridian is round wire, the weft line is a flat wire.

2. How to choose a Shading net

1. color

The commonly used Shading nets include black, silver -gray, blue, yellow, green and other types. Black and silver -gray are used most commonly in vegetable coverage.The lighting and cooling effect of the black Shading net is better than the silver gray shade net. It is generally used for crops with low temperature and high temperature seasons and low requirements for light and light viral diseases.Capelles and other green leafy vegetables such as coriander and spinach.The silver -gray Shading net has good light transmission and has a aphido effect. It is generally used in the early summer, early autumn and the requirements of high -oriented virus diseases, such as radishes, tomatoes, Pepper and other vegetables.It is used for winter and spring anti -frozen coverage. Black and silver -gray Shading nets are available, but the silver -gray Shading net is better than the black sunshade net.

2, Shading rate

During the weaving, the shade net can regulate the density of the weft, so that the shielding rate can reach 25%to 75%, or even 85%to 90%.You can choose in different needs in the cover cultivation.Xiaqiu covers cultivation, and the requirements for light are not too high. The small cabbage and other green leafy vegetables with high temperature can be selected from the Shading net with a high shielding rate.

For fruit and vegetables with high light requirements and high temperature resistance, you can choose a sunny net with a lower lighting rate.winter -spring anti -frost and anti -cream covers is effective with a sunshade net with a high shielding rate.In general production applications, the Shading rate is generally selected from 65%to 75%of sunshade nets.When using it, it should be adjusted according to different seasons and weather conditions, by changing the time to cover and adopting different cover methods to meet the growth needs of different crops.

3. Width

The range of general products is 0.9 meters to 2.5 meters, and the widest is 4.3 meters. Some manufacturers can also be customized as needed.The use of 1.6 meters and 2.2 meters is currently more common.In the coverage cultivation, multiple stitching is used to form a large area of coverage. It is convenient to unveil the cover during use, easy to manage, save labor, save effort, and facilitate fixation. It is not easy to be scratched by strong winds.It can be stitched according to the length and width of the coverage area.When cutting the Shading net, the cutting iron should be scalded with electric iron.When stitching, the cotton wire cannot be used, and the nylon wire should be sutured to increase the stitching firmness.

1. The life of the shade net is a few years

The service life of the Shading net is mainly related to the production materials, the environment, and the method of use. Generally speaking, the service life of the shade net ranges from 3 to 5 years, but if the production materials of the shade net are poor or the environment is harsh, then the environment is harsh, then then the environment is harsh.The service life of the shade net will be reduced a lot.

The Shading nets on the market are mainly divided into two types of production materials, one is the raw material is high -density polyethylene, and the other is the melting plastic particles melted with the two -recovered waste plastic and Shading net.And regeneration.The Shading nets produced by native materials are light, strong, strong, and durable. The service life is generally three to five years, and the price is slightly more expensive.The use of the Shading net produced by regeneration is only one to two years, and it will often be damaged after one year.

The service life of the shade net is also related to the environment and the method of use.The same Shading net will have a longer service life in the north than the life of the south. This is mainly due to the hotter weather in the south, and the sun radiation of the shade net is stronger.The internal network life of the shade net is longer than the life of the external network. The time exposed to the sun and the sun radiation intensity of the received will also affect the service life of the shade net.

Therefore, when you buy a Shading net, if you want good quality shade nets, do not greedy to buy a Shading net for cheap buying regenerative materials, resulting in a shorter service life, which will not achieve the expected results and suffer losses.

2. How to maintain a sunny net

1. Because the Shading net is made of polyester material, the texture is soft, Smooth, and durable. Therefore, it is necessary to pay attention to preservation when using a Shading net. Proper collection storage can extend the service life of the shade net, so as to achieve the purpose of multiple uses.Essence

2. When collecting the Shading net, it is best to choose it on a cloudy day, lay the net on the ground, and roll it up after drying.If there is water stains on the shade net, you need to wait for the water stains to be dried and then roll up.

3. It is important to note that the Shading net should avoid soil pollution as much as possible. If it is contaminated, it can be cleaned with a sprayer and put it away after drying.

4. Finally, the shade net should be stored in ventilation, avoiding the light, and on the shelf, pay attention to the antids and mouse bite.In this way, the Shading net can be used for a longer time.
