1. Which of the Shading effect of aluminum foil Shading net and black net is better

1. Material comparison

Aluminum foil Shading net is a Shading material composed of multi -layer fiber mesh, aluminum foil, and PE anti -ultraviolet material. It has excellent ultraviolet -resistant, shielding, heat insulation and other properties, and has strong durability and compressive resistance.The black net is a Shading material made of HDPE material, which has the advantages of sunscreen, shielding, breathable, etc. Its advantage is that the price is cheaper and has good light transmission performance.

2. Comparison of Shading effect

The aluminum foil Shading net has a good Shading effect. Its special structure allows it to reflect the sunlight of the sun, reduce the direct radiation of the Solar, maintain temperature and increase water evaporation, thereby improving plant yield and growth quality.The anti -ultraviolet effect of this material is also excellent, which can effectively avoid the damage caused by ultraviolet rays to plants.The black net's Shading effect is slightly inferior to the aluminum foil Shading net, but for some occasions that need light transmission, the black net is a more suitable choice than the aluminum foil Shading net.

3. Select suggestions

When choosing a Shading material, we must first consider the application scenario. If the material is required to have anti -ultraviolet rays and Shading effects, it is recommended to choose an aluminum foil Shading net; if the material is better, you can choose the black net.In addition, the price of aluminum foil Shading net is relatively high. If the requirements are not high and the price is low, you can choose the black net, but you should pay attention to the quality of the material to avoid waste from buying inferior materials.

In summary, the aluminum foil Shading nets and black nets have their own advantages and disadvantages, and appropriate materials need to be selected according to actual needs.When purchasing, you should try to choose materials with quality and guarantee. Do not choose inferior products for cheap or other reasons, causing unnecessary economic losses.

2. How to distinguish the quality of the shade net

1. Material

The high -quality Shading net uses new polyethylene as the raw material, adding imported ultraviolet absorbers, antioxidants and good female mother production.

The inferior Shading net is made of recycling materials (old materials, flower materials) and inferior colors, and the ultraviolet absorbers and antioxidants are not added.

2. Appearance

The high -quality Shading mesh surface is flat, Smooth, shiny, uniform and clear with latitude and weft. In the sun, the color is black and black, the color is small, and the silk has no overlap.

The inferior Shading mesh surface is uneven, no gloss, no light, uneven latitude and weft, with gray black in the sun, large color difference, the silk mesh contains impurities, and the silk mesh overlap.

3, feel

High -quality Shading net feels soft, not rough, not stiff, and elastic.

The inferior Shading net has a rough feel, a bit stabbing, feels thick, and non -elastic.

4. Smell

The high -quality Shading net has no odor, and some are just a faint plastic scorching flavor.

The inferior Shading net is unpleasant, pungent, and plastic scorched flavor.

5. Quality

High -quality Shading nets have a Square gram of heavy gram, and the width and length are accurate. There are no holes in the mesh surface, no filament, strong single silk elasticity, and strong tensile ability.

The Square gram of the inferior Shading net is not standard, the width length is inaccurate, the mesh is hole, the silk is severe, and the single silk has no elasticity and no tensile force.

6. Life life

High -quality Shading nets have been used for more than 3 years under natural climatic conditions (excluding membrane, sulfur corrosion and polymeter areas).

The inferior Shading net is less than 1 year under natural climate conditions.

7. Economy

The high -quality Shading net is generally calculated according to the Square number, and the surface price is high.However, due to the light weight of the mesh, the actual length is accurate, the area is large, and the service life is long. It is much more affordable to calculate according to the service life of peace.

The inferior Shading net is generally calculated according to weight, and the surface price is low.However, due to the weight of the webbage, the actual length is insufficient, the use area is small, the service life is short, the labor cost is high, the cost of the shed is high, and it is not affordable.

1. What kind of sunshade mesh and web needle is more solid

The flat needle Shading net has a closer structure, smaller acupuncture pitch, stronger and durable, longer service life, good toughness, not easy to break, and strong wear resistance.The network needle is resistant to corrosion, which can be used in humidity, and at the same time, ventilation is better.Therefore, the specific choice of the Shading net should be selected according to the environment and requirements.

2. Which sunscreen mesh and oblique needle is durable

The durability of the oblique needle.The Shading net with the same material and needle is better to choose a diagonal needle.Because the oblique needle is more firmly woven, it is not easy to occur during use and damage.Relatively speaking, the durability of the flat needle is not strong, so it is recommended to choose the oblique needle when choosing a Shading net.The oblique needle's Shading net has a good effect on disaster relief and income. During the use process, it must be straightened, tightened, and flattened. There must be no low places. Otherwise, it is prone to stagnant water falls on rainy days, causing the net to be damaged.

3. precautions for Shopping.com

1. When buying a Shading net, many people are very easy to buy a net with a high shielding rate, which is mistaken for the high shielding rate.However, too high shielding rate causes weak light in the shed, reduced photosynthesis of crops, weak stems, and long -term problems, which reduces the production of crops.So try to choose the Shading rate as low as possible when choosing a Shading net.

2. When buying a Shading net, try to choose a guarantee product with big manufacturers and brands, and determine the use of products that have been used for more than 5 years on the greenhouse.

3. The thermal contraction characteristics of the shade net are easily ignored. The most contracted in the first year, about 5%, and gradually become small.With its contraction, the shielding rate will increase.Therefore, it is necessary to consider its thermal contraction characteristics when using a card slot.

1. What does it mean?

The Shading net is divided into scriptures and weft, and the edited Shading net is divided into several needles according to the different weaving needle distance.How many shots of the Shading net refer to the number of pins in each inch. The more the number of pins, the dense the network.Depending on the number of needles, the Shading net can be divided into one shot Shading net, two -needle Shading nets, three -needle Shading nets, and more pins.Of course, due to the difference in the number of Shading mesh pins, the fields and environments they are used will be different.

1. One needle Shading net

One shot Shading net is a mesh composed of a weir silk within a one -inch distance.Its weight is about 5 to 10 grams per Square meter.It is mainly used on the outer packaging on project products, replacing the traditional hemp cloth packaging to prevent humidity, rust removal and anti -rust.

For Xiguang flowers, when using a Shading net, most of them can be used with two or three stitches.The demand for light is not highflowers, Most of them can be used with a four -needle.

1. What are the coverage of Shading nets?

In the southern area, the coverage of the shade net is mainly covered with floating surfaces, large, medium, and small flat sheds, large, medium, and small arch sheds covered, and there are also a small amount of greenhouse coverage.

1. Floating surface coverage

It refers to the coverage of the coverage directly on the ground or plant with a Shading net.The annual use of this method is mainly used for the coverage of vegetables from sowing to the seedling period, and the Shading net is unveiled after the seedlings.The effects of Shading, cooling, moisturizing, and riot rain in summer, the effects of preventing rain, heat preservation, and moisturizing in winter to create favorable conditions for seeds germination and seedlings.During the day, the method of unveiled at night to shorten the seedling period and improve the seedling rate. In addition, it can be used to cover the floating surface 7-10 days before the harvest of the late summer and autumn.

2. Single -type small flat shed covered

For the main coverage of leafy vegetables, bamboo poles, bamboo pieces, wooden sticks, cement columns and other materials can be used on the noodles of about 1 meter to cover the shade net.Generally, floating surface coverage after sowing or transplantation, the long-visited types of crops, weather and other conditions of the coverage time are depends on. The high temperature during summer and autumn should be covered by 15 days.Gaerry and cauliflower are covered with 20-25 days. Symphony, small mustard, lettuce, kale, celery, etc. can be covered with full fertility period. When the weather turns cold in autumn, kale, mustard, Chinese cabbage, broccoli, cauliflower, lettuce, etc.Cover 15-20 days.

3. Zhongping shed coverage

Use 1.5-1.8 meters long, 0.33 cm Planted pipes to set up a simple flat shed on the noodles, cover the sunshade net, and the Shading net should be flat and straight, about 1.5 meters high.50 cm, preventing the typhoon from being blown down. This method is simple, the cost is low, the field operation is also convenient, and the ability to resist typhoons is better.Suitable for leafy dishes, early or full -blooming.

4. High flat shed coverage

The height is 1.8-2.0 meters, and the cement column with a length of 2.2 meters and a thick 12 cm X10 cm is used as a water pipe and iron wire fixed bracket.There are more materials, installation, and low ability to resist typhoons.Suitable for leafy vegetables to cultivate or eggplant fruits, early coverage of melon Beans, etc.

5. Small and medium arched sheds cover

It refers to the use of the skeleton of small and medium arch sheds as support, covering the coverage of the shade net.It is mainly used for seedling, transplantation, early cultivation of autumn vegetables or anti -season cultivation.The center of the small shed is about 0.5-1.0 meters high, about 1.0-1.5 meters wide, 7-8 meters long or base blocks.The center of the middle shed is about 1.0-1.5 meters, 2-3 meters wide, 10-15 meters long or base blocks.

6. Greenhouse coverage

It refers to the use of cement, steel, etc. to cover the shade net for skeleton materials or cover the Shading net on a plastic film greenhouse.It is mainly used for seedling, summer and autumn vegetables delayed or early -maturing cultivation, and can also be used for some vegetables such as leafy dishes or some fruits of winter and anti -season cultivation.The center is about 2.5-3.0 meters, 6-12 meters wide, 40-55 meters long, and covers an area of 333.3-666.7 Square meters.

7. Greenhouse coverage

It refers to the coverage of the Shading net on the greenhouse.It can be divided into two ways: flat sheds on the top of the greenhouse and the flat shade net sky curtain in the greenhouse.Outdoor coverage is better than indoor coverage. It is good for ventilation and heat dissipation and cooling.It is mainly used for anti -season cultivation, postponed cultivation in summer, or early -maturing cultivation of autumn vegetables.

2. precautions for covering the shade net in summer

Covering the Shading net is the most commonly used cooling method in the high temperature season, but the wrong coverage method will affect the cooling effect and even play a negative role.

1. It is best not to close the shed

Black Shading nets absorb more heat, which will directly pass the heat to the shed to shorten the life of the shed film. At the same time, the heat of the coverage of the shed is slowly disappeared, and the ideal effect of cooling down can not be achieved.

How to use it correctly: It is recommended to keep a distance of 0.5-1 meters from the shade net and the shed surface to ensure that the air between the shade net and the shed surface can flow, which can accelerate the loss of heat in the shed, but also achieve a good Shading effect, reduce the shed shed sheds, reduce the shed sheds.Heat is hot.

Practice has proved that compared with the setting of the shade net and the shed film, the temperature in the former is 5 C or more than the latter.

How to make the shade net and the shed film open?

When a single greenhouse is covered with a Shading net, vegetable farmers can put two earth Bags with two film pressure membranes on the steel frame structure or large bamboo pole at a certain distance.

For bases or parks and places where greenhouses are relatively concentrated, automated Shading equipment can be used.During the specific settings, the steel pipe stent is preset at the back wall, the gables on both sides and the front face, about 1 meter from the shed, and the shed surface is equipped with a steel wire, covering the shade net on the steel wire, and the support network is set at 0.5 meters.Rope to fix the Shading net.

Finally, install the nose of the machine on the steel pipe at the front face of the greenhouse. In this way, just hold the remote control and press the button to easily complete the stretching of the shade net.At the same time, the Shading area can be flexibly adjusted in combination with weather conditions.

2. The Shading time should not be too long

The coverage of the shade net is too long, which will affect the photosynthesis of vegetables and is not conducive to the normal growth of vegetables.Vegetable Shading should be combined with weather conditions, vegetable types and vegetable growth stages. The requirements for light intensity and temperature are flexibly grasped.

Materials used for Shading, such as Shading nets, generally use sunny covers and unveil on cloudy days; lid at noon, in the morning and evening;If there are many rainy weather and the temperature is not too high. After the vegetables are planted, the shade material can only be covered in the slow seedling stage.In addition, when a long -term sun or root disease occurs, vegetable farmers can also use Shading nets to avoid the occurrence of plant withering.
