1. How much is one meter for Shading net?

The unit price of Shading nets will be affected by factors such as different brands, materials, mesh density, Shading rate, production technology, supplier, etc. Therefore, the unit price will be different. You can contact the local shade net supplier to consult the specific price.The price range of general Shading nets is 30 yuan to 100 yuan/Square meter.

2. How to buy a Shading net online

First, choose the shopping software you often use, such as Taobao, JD.com, Pinduoduo, or Alibaba. After opening the software, enter the Shading net in the search bar, and then click to search.There is a price, and then select the specifications, materials, color, etc. of you, then choose to buy and enter your payment password.

When buying, we must first confirm whether it is a round Shading net or a flat silk Shading net.The shredded Shading net is like a fish line, and the flat wire is sliced.Ordinary flat wire Shading nets can use the number of needles and Shading rates as the purchase standard.For example, the density of the 50%Shading rate and the 70%Shading rate of the same 3 needle is different.The Shading net with a 70%Shading rate, if compared with 3 stitches and 6 stitches, 6 stitches will look more dense.Therefore, when purchasing, the number of needles and Shading rate should be selected.

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

How many pins of the Shading net represent the number of pins in each inch. The more the number of stitches represents the densely the eyes, 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 breathable.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. The benefits of covering vegetable cultivation

1. Prevent the impact of heavy rain

After covering the shade net, the heavy rain can be turned into small rain to prevent the direct impact of rainwater on seeds, seedlings, plants and soil. Therefore, the coverage of the shade net can play a role in improving the seedling rate, protecting the seedlings and preventing soil plate knots, avoiding heavy rain pairs.The mechanical damage caused by plants and promote the growth of plants, which is the main reason why summer and autumn covered with cultivation leafy dishes.

2. Prevent the radiation of strong light

After covering the shade net, it can prevent strong light radiation, which can greatly reduce the rate of sowing or transplanting the seedlings or transplants in the summer and autumn high temperature and strong light season.At the same time, after covering the shade net, it is also conducive to the photosynthesis of vegetables and improves yield and quality.

3. Reduce temperature

In the southern region, due to the effect of high temperature in summer, it is extremely unfavorable to the growth and development of plants. After covering the Shading net, it can reduce the temperature in the network, create a more suitable temperature environment, avoid the adverse effects of high temperature on plant crops, and promote the promotionThe growth and development of plants are conducive to the potential for production.

4. Reduce evaporation, moisturizing and drought -proof

The covering net covering cultivation vegetables can not only greatly reduce Solar radiation, but also reduce the evaporation of soil moisture. It can reduce the amount of water evaporation by about 60 % -70 % than the open field cultivation, thereby reducing the number of watering and irrigation, increasing the high temperature and drought seasonThe moisturizing ability of the soil is conducive to plant growth.

5. Insulation and cold, anti -frost

In addition to the cultivation of summer anti -thermal and rainfall coverage, the Shading net can also be used for early spring prevention and night cream, late autumn prevention early frost, autumn and winter anti -freezing damage and other coverage cultivation.It is used when the temperature is low in winter. When it encounters severe frost, it can delay the occurrence of frozen merging process, reduce frost damage, and make the crops safely overwinter.

6. Reduce disease

After covering the Shading net, it can significantly reduce the occurrence of virus disease, especially the aphid avoidance and anti -virus disease covering the silver -gray shade net. Generally, its anti -prevention efficiency can reach more than 85 %.

7. Improve the survival rate of seedlings and the quality of seedlings

The high temperature and strong light in the south in the south make seedlings more difficult, the survival rate of seedlings is low, and the seedlings of seedlings are poor. In the summer, the use of Shading nets is covered with cultivation seedlings, which can improve the quality and survival rate of seedlings.20 % -80 %, comprehensive indicators such as plant height, development, leaf number, stem thickness, and single plant weight can be increased by 30 % -50 %.

8. increase output and relieve the off -season

In the southern area, summer and autumn are affected by tropical cyclone, high temperature, high humidity, high temperature drought, and strong light. It is extremely unfavorable to plant growth and development. It is difficult to produce and decline in production. It is the main reason for the summer and autumn season.The use of Shading coverage can effectively solve the problem. Generally, it can increase production by 20 % -50 % or more, and the income increase of about 30 % -100 %.Therefore, the coverage of the shade net can increase the variety of market color, improve production and quality, and alleviate the tension of production and supply of off -season production and supply have important practical significance.

9. Easy to use, save labor, reduce production costs

Compared with the traditional coverage materials, the Shading net covers the advantages of high strength, aging resistance, light texture, convenient use of transportation, low labor strength, etc., and also has provincial labor, low energy consumption, low cost, high yield, high -efficiency, high -efficiency, efficient, high -efficiency, and efficient efficiency.Features.

2. How good is the Shading rate of the vegetable Shading net?

When buying a Shading net, we must first clarify how high the Shading rate of your shed.Under the direct sunlight in summer, the strength of the light can reach 60,000 to 100,000 Lax. For vegetables, the light saturation point of most vegetables is 3-60,000 tolex.Lax, 55,000 cucumbers, and 70,000 Lax's light saturation points of tomatoes.Excessive light will affect the optical fitting effect of vegetables, leading to the absorption of carbon dioxide, excessive breathing strength, etc., and the phenomenon of optical "lunch break" in natural conditions is created.Therefore, the use of a suitable Shading metering net can not only reduce the temperature in the shed around noon, but also improve the optical efficiency of vegetables, and get two birds with one stone.

The black Shading metering rate is high, which can reach 70%. Using a black sunshade net, the light strength does not meet the normal growth needs of tomatoes, which can easily cause tomato to grow long and lack of photosynthetic products.Most of the silver -gray Shading mesh is 40%~ 45%, and the light transmission rate is 40,000 to 50,000 Lax, which can meet the normal growth needs of tomatoes.So tomatoes are best covered with silver -gray Shading nets.You can choose a Shading net with a high light saturation point with peppers. For example, the shielding rate is 50%-70%to ensure that the light in the shed is about 30,000 Lax;For the type of vegetables, you should choose a Shading net with a low shielding rate, such as 35%-50%of the shielding rate, and ensure that the light in the shed is 50,000 Lax.

1. Why do greenhouse greenhouses use Shading nets

1. Over -Shading effect

The Shading net reduces the intensity of the light in the greenhouse. The larger the density specifications, the better the Shading. The same specifications are better than silver -gray Shading.

2. Cooling effect

The temperature in the shed decreased due to the coverage of the shade net, and the cooling of the surface and soil farming layer was ideal. At 10 am -at 2 am, the temperature of the upper part of the greenhouse was 37-40 C, and the temperature around the surface plants was 22-26 C. The soil was soil.The temperature is between 18 and 22 C, which is suitable for crop growth.

3. Baoyao anti -strict rain

The evaporation in the shed decreases, the soil water content is higher than the dew, and the surface soil is moist.Because the Shading net can break down the rainstorm into drizzle, the free leaves are injured by heavy rain, and the soil is not easy to end. The gap is large and the ventilation is good.

Based on the above effect of the Shading net, many greenhouse vegetable growers generally choose to cover the Shading net in the greenhouse plastic film. In this case, the Shading effect is better, which is more beneficial for crop growth.

Second, the Shading net is placed inside the greenhouse or outside

1. When the Shading net is placed outside the greenhouse, because it directly blocks the sunlight outside the greenhouse, it makes its light calories not transmitted to the inside of the greenhouse, thereby achieving a certain cooling role while covering the light, thereby playing a certain cooling role, therebyIt is also more conducive to avoiding the radiation of strong sunlight, thereby reducing the impact of high temperature on vegetable growth.

2. When the Shading net is placed inside the greenhouse, the Solar light can still enter the interior through the greenhouse film, so that the heat will also be brought in, so this method of use will not change the internal temperature, but it can cover the Solar ray of the sunlight.The impact on vegetables is suitable for vegetables that require temperature but also want to avoid ultraviolet irradiation.

Only by mastering the correct usage method and clearing the different functions produced by different use methods can we play the role of the shade net to the point, which is more conducive to the good and rapid growth of vegetables, thereby bringing a considerable economy to the growers to bring a considerable economybenefit.

1. What color is good for Shading nets?

There are many colors of Shading nets, such as black, white, green, blue, yellow, red, silver -gray, etc. So, what color is good for Shading nets?

The color of the Shading net is added in the process of making raw materials. At present, the shade net sold on the market is mainly black and silver -gray. The Shading net color should be selected according to the type of vegetable types.

The black Shading mesh is high and the cooling rate is fast, but it has a greater impact on photosynthesis. It is more suitable for use on leafy vegetables. If used on some happy vegetables, the coverage time should be reduced;It has a small impact on photosynthesis and is suitable for eloquent vegetables such as eggplant fruits.

2. Why is the Shading net black

Black Shading net is a very suitable Shading Tool for vegetables that need light. This is because black is weaker than any color reflecting Solar light, that is, the ability to absorb sunlight is the strongest.When the sunlight transversed from the Shading net, the energy (thermal energy) of the Solar light has been consumed, and the following is naturally cool.So it is very suitable for the growth of crops.What we have seen on the market currentlyShading netMost of them have two colors, one is black and the other is gray, and the black effect is also a wider range. The gray ability is not black, so it is generally used on the crops of Xiguang.
