However, when used alone, it is recommended to choose silver or black, and when used in combination with tinting, white is recommended. Grids are usually chosen between 20 and 40 grids.

The insect-proof net should be completely closed, and the surrounding area should be firmly pressed with soil and firmly fixed with laminated lines. Doors entering and exiting large and medium-sized shelves and greenhouses need to be installed with inspection and protection nets, and be careful to close them when entering and leaving. Cultivation of small arched protection nets, the height is significantly higher than the crops. It is essential to avoid leaves sticking to the inserted protective net and to prevent pests from eating or laying eggs outside the net. The inspection and protection net used to close the air outlet shall not have a gap with the transparent cover, so as not to leave an entry and exit channel for pests. Check and repair holes and gaps inserted into the protective mesh at any time.

Common sense of application of dust nets on construction sites

 

The basic situation and common sense of the application scope of Olive Net For Agriculture. In the next issue, the editor will share with us some relevant information in the survey, hoping to change our prejudice and have a deeper understanding of the dust net on the construction site. In this way, we can also know what to pay attention to when purchasing and using the dust filter at the construction site. Don’t panic, I hope it inspires and helps us.

The construction site dust net uses the principle of aerodynamics and is processed into a certain shape, opening rate and different combinations of air holes according to the air hole test results of the construction site environment, so that the flowing air (strong wind) can pass through the wall from the outside. At this time, an upward and downward stirring airflow is formed in the wall, the outside wind is large, the inside wind is weak, the outside wind is small, and there is no wind inside the wall. The interior is used to avoid dust flying. This skill is currently in a major position in the country. The wind and dust suppression wall is composed of three parts: independent foundation, steel structure bracket and wind deflector.

Field dust net use:

China Building Net Factory‘s construction site dust net is mainly used to prevent people and objects from falling, reduce the injury of falling objects, protect the safety of high-altitude workers and pedestrians and clean the site. Features: high mesh density, the general vertical dust mesh is 800 mesh/100 square centimeters, and the mesh density of this product is 2000 mesh/100 square centimeters. Therefore, when objects with a bottom area of less than 100 square centimeters, such as gravel and bricks, fall, their dust-proof function is much greater than that of ordinary dust-proof nets.

 

How Shade Netting Suppliers Are Windproof

The weather is too hot, how to release the insect net

The weather is hot in summer, how can shade netting suppliers let out the wind and prevent insects in the planting greenhouse?
Recently, the continuous high temperature in the country has lasted for more than half a month, and the temperature is as high as 40 degrees. The temperature in the greenhouse is even higher, which will cause high temperature damage to our crops!
First of all, in order to prevent cold air from entering, the general greenhouse will put on the windshield. In summer, we can remove the windshield!
Second, you can replace the gauze of the air vent with a lower mesh, so that the ventilation will be better and the air vent will be enlarged!
Third, you can add air vents on it if you have the conditions, and you can add a fan if you have the conditions!
Fourth, the agricultural insect net supplier china removes the straw curtain on the greenhouse, and the area of the air vent on the top of the greenhouse can be opened to a large size, which can accelerate the discharge of high-temperature air in the greenhouse.

 

Mesh Number Of China Agricultural Insect Net

How to calculate the number of insect nets? What is the effect of different meshes?

The number of meshes refers to the particle size or thickness of the material. The general definition refers to the number of meshes in the area of 1 foot * 1 inch, that is, the number of meshes of the screen, and the number of meshes that the material can pass through is defined as how many Mesh number; china agricultural insect net is a new type of agricultural covering material. It is made of high-quality polyethylene as raw material, added with chemical additives such as anti-aging and anti-ultraviolet. Correct storage life of up to 3-5 years. Choose appropriate specifications – the specifications of organic vegetable insect control nets include width, aperture, wire diameter, color, etc. In particular, attention should be paid to the aperture; if the mesh is large, it will not achieve the proper insect-proof effect; if the mesh is small, the shading will be too much, which is not good for crop growth.

At present, the suitable mesh number is 20-32 mesh, the wire diameter is 0.18 mm, the width is 1.2-3.6 meters, and it is white. If you need to strengthen the shading effect, you can choose a black insect net. Silver-gray insect nets are better at preventing aphids. The biggest feature is that it can prevent insects and diseases, and greatly reduce the amount of pesticides used. It is the key technology of pollution-free vegetables and a simple, scientific and effective insect control measure.

The 25-mesh vegetable greenhouse insect-proof net has little effect on the temperature and relative humidity in the greenhouse, but it delayed the appearance of high temperature and low humidity in one day. In the experiment, the high temperature was delayed by about 4h, and the low humidity was delayed by about 2h. The 25-mesh insect-proof net covered with Certain shading effect. Therefore, it has a buffering effect on the rise of temperature and the fall of humidity in the shed; because the mesh of the 25-mesh insect-proof net is sparse and the shading rate is low, the high and low values of temperature and humidity are basically the same as the control.

40 mesh vegetable greenhouse insect-proof net has a greater influence on the temperature and relative humidity in the greenhouse than 25 mesh. The change trend of temperature and humidity in the shed covered with 40-mesh insect-proof net was basically the same as that of the control, but the change range decreased and the relative humidity increased. In cloudy weather, due to the dense mesh of the 40-mesh vegetable greenhouse insect-proof net, high temperature and low humidity occur in the greenhouse, which has a greater impact on the growth of vegetables.
Overall comparison, the 25-mesh mist net for sale covers little change in temperature and relative humidity, and has little impact on the growth of vegetables. At the same time, the 25-mesh insect net for sale can block most pests, such as Bemisia tabaci, cabbage caterpillar, cabbage borer, diamondback moth, Aphids, flea beetles, beet armyworms, Liriomyza sativa, Spodoptera litura, etc., also reduce the spread of virus diseases, sooty diseases and other diseases. In production, it is generally recommended to use about 25 mesh insect control nets.

The Use Of Insect Net Supplier Anti-bird Net

sunshade netting is a kind of mesh fabric made of polyethylene and heald with anti-aging, anti-ultraviolet and other chemical additives as the main raw materials, and it has high tensile strength, heat resistance, water resistance, corrosion resistance, resistance to It has the advantages of aging, non-toxic and tasteless, and easy disposal of waste.
1. Set up anti-bird nets

The bird-proof net is suitable for both large-area orchards and small-scale orchards. It is best to use yellow bird-proof nets in orchards in mountainous areas, and red bird-proof nets in plain areas. These are the birds in mountains and plains. The two most feared colors.

In areas with frequent hail, it is a good measure to adjust the size of the grid and combine the hail-proof net with the bird-proof net. However, the average cost per mu of anti-bird nets is high, and the service life is short. Fruits must be collected after harvest every year, which is labor-intensive, and it is easy to age and break when exposed to the scorching sun and strong wind, especially in some vineyards in Jiangsu and other vineyards at the beginning of this year. The bird-proof net was damaged due to the collapse of the heavy snow, and the loss was huge.

2. Fruit bagging

Ear bagging is the easiest way to prevent bird damage, and it also prevents the effects of pests, pesticides, dust, etc. on the ear.

Use good quality and tough paper bags. In areas with many birds, nylon mesh bags can be used for bagging, which not only prevents bird damage, but also does not affect the coloring of fruits, but the relative cost is relatively high. At the same time, bagging can only be effective for grapes, apples, pears, etc., but not suitable for cherries and blueberries.


3. Improve cultivation methods

In areas where bird damage is common, keeping more leaves, covering the fruit ears, and paying attention to the hygiene conditions around the orchard can also significantly reduce the occurrence of bird damage.

4. Add isolation network

For some fruits, such as raisins, the entrance and exit of the drying room, the vents, and the ventilation holes are set up with barbed wire and nylon nets of appropriate specifications in advance to prevent the entry of birds.
