Introduction and Selection Standards Of Greenhouse Accessories

With the development of agriculture, the greenhouse planting area is getting larger and larger. The expansion of planting area means that the number of greenhouses will increase, and the construction of greenhouses will require the use of greenhouse accessories. Then the following introduces the types of greenhouse accessories.

U-shaped card: It is shaped like "U", so it is named U-shaped card. It is used at the intersection of the stay and the arch pipe, and it has a fixed effect on the stay and the arch pipe.

Card slot: also known as film slot, that is, a slot for pressing a film. The connection between the card slot and the card slot requires a connecting piece.

Connecting piece: connect the two card slot ends with the ends without any external objects to fix.

Card spring: card spring has two types: plastic dip card spring and plastic card card spring. Its main function is to fix the film in the card slot, which is fixed firmly and not easy to fall off. Tube slot holder: Its role is to fix the card slot to the arch tube. It is firmly fixed, not easy to fall off, and convenient for disassembly for secondary installation.

Greenhouse electric motor roller: It is divided into a film rolling device and a film rolling rod, which are installed on both sides of the greenhouse. The middle part of the two card slots is to wrap the film outside the film rolling rod. Membrane pole, which rolls up the film (apron) between the card slots, and plays a ventilation role in the greenhouse. Generally, the distance between the ventilation channels is one meter.

Film laminating line: After the film is installed, press the film between the two arch pipes through the film laminating line. The advantage of using a film line is that it is not easy to hurt the film, and it can also hold the film tightly. The bottom end of the film line can be buried in the soil through a ground pile, or it can be directly tied to the brick and buried in the soil.

Shed head combination: including door head post and door. Film: 8 wires, 10 wires, 12 wires. Laminated card: used in two aspects, one is to clamp the film on the film roll; the other is to clamp the film on the arch pipe of the shed, which is not easy to damage the film and can be fixed well.

Greenhouse Accessories

Selection criteria of greenhouse accessories:

Greenhouses can often bring us relatively many experiences, so we need to take care of our work carefully when selecting them. For example, in order to make the greenhouse accessories truly function, they often need to make strict selection and implementation standards in terms of their performance.

The following greenhouse manufacturer introduces the selection criteria of greenhouse accessories. For example, some greenhouses often require a lot of light transmittance, because it can be seen that the greenhouses can play a practical role, mainly because they have a good daylighting rate. Therefore, when choosing a professional greenhouse accessories factory, we often need to choose some products that have obvious advantages in light transmission. This can bring us a lot of convenience. At the same time, in order to solve these problems, improvements are often made according to the growth characteristics of plants. Some plants have high requirements on light transmittance during the growth process, so they need to make suitable choices.

When choosing accessories, it is often necessary to pay attention to whether it has good thermal insulation performance. Because when planting crops in winter, you can often see that the right temperature is a particularly critical factor, and only the appropriate choice of accessories products that have a good advantage in thermal insulation performance. Therefore, when choosing accessories, it is often necessary to see whether it has good thermal insulation performance, so that the product can be used well.

What Accessories are There in a Greenhouse?

Greenhouse accessories can be divided into two categories: standard accessories and optional accessories. Needless to say, standard accessories are indispensable in greenhouse accessories. In general, accessories can be divided into two categories, that is, standard accessories and optional accessories. greenhouse manufacturer introduces you as follows:

Standard accessories are accessories that come with the machine. Although the standard configuration differs for each model, common standard components are memory and cardboard boxes. Of course, the size of the memory and the capacity of the paper feed tray are different for different models. The standard configuration can be understood by referring to the product description. Without the standard configuration, the use and performance of the product will be affected to some extent.

Optional accessories are those parts that, in addition to the standard configuration, can enhance product features and improve product performance. They need to be purchased separately. And the use of the basic functions of the product is not affected by the use of optional accessories. There are many types of optional accessories, and different products support different optional products. Therefore, when selecting accessories, you should check the product manual in advance to avoid purchasing unusable accessories. 的 A good combination of various accessories in the greenhouse can have a reasonable environment for growing vegetables. Therefore, it is important that any one component in the greenhouse is very important. Today I will share some experience with you the specific details of using the greenhouse card slot:

First, in order to facilitate ventilation and ventilation management, the roof film and skirt film of the greenhouse need to be covered separately. There are usually three types of film covering, one roof film and two left and right skirt films. The ceiling film width is 7.5-8.0m, and the skirt room film width is 1.2m .. First, install chucks on the apron film on both sides, and then clamp the apron film cover with spring chucks at both ends. Each arch is clamped with a film line (belt). At the junction of the aprons and the aprons, the aprons should overlap by 20-30cm. The apron film is pressed on the outside of the apron film. The rocker can be installed on both sides of the skirt film to facilitate ventilation and exchange of the skirt film. A part of the skirt is sealed with soil. When the greenhouse is covered, windless weather should be selected to avoid unfavorable wind blowing or tearing of the greenhouse film, and the film belt is pressed after the covering.

2. When the greenhouse is ventilated, first raise the top film side, raise the temperature again, and lower the skirt film. Prior to lowering the skirt, the skirt is clamped or tightened, and the film covering film proceeds in reverse order.

3. After the greenhouse is completed, excavate deep trenches around the greenhouse to lower the groundwater level and facilitate the growth of vegetables in the greenhouse.

Finally, during the use of the greenhouse, the greenhouse film is covered by dust for a long time, which directly affects the light. After a test of 10u on a sunny day, the light transmittance at the flushing place of the roof coating film is 25% different from that at the non-washing place. Therefore, regular cleaning of the greenhouse film and keeping the greenhouse film clean is one of the important means to improve the use of the greenhouse.

Advantages and Disadvantages of Greenhouse Construction for PC Sun Panel

1. Features of PC sunlight panel greenhouse

The custom pc board greenhouse supplier believes that because of its good thermal insulation performance, strong impact resistance, light weight, large installation size, long service life, beautiful appearance, good visual experience, and initial light transmittance, With many advantages, the PC board greenhouse was once regarded as "the latest greenhouse structure" and was highly respected by greenhouse builders and greenhouse manufacturers. Until now, the application of PC board light-transmitting materials in greenhouses has gradually increased.

In this way, the custom pc board greenhouse seems to have particularly obvious advantages, and it seems to have become a replacement product for glass greenhouses, because in their view, the cost of the greenhouse built by PC sunlight panels is lower than that of glass greenhouses, and other The performance is not bad.

2. Transparency of PC sunlight panel greenhouse

However, the production practice of pc board greenhouse china over the past few years has shown that the PC board greenhouse  is not so perfect, first of all in the light transmittance of the greenhouse. Generally, the initial light transmittance of 10mm thick hollow PC sheet is 78% (manufacturer's published laboratory measurement data), which is 10% to 15% lower than single-layer plastic film, and 10% lower than 4mm thick float glass. This disadvantage is accompanied by lifetime And the plastic film can be replaced within 3 ~ 5 years to restore the light transmittance. The light transmittance of the glass material hardly changes with time, but the light transmittance of the PC board material is within 10 years of the manufacturer's guaranteed service life. Weakened (general manufacturers promise that the light transmittance of the material will not drop by more than 6% within 10 years. For the time being, I believe the manufacturer said that even after 10 years, the material light transmittance is only 72%).

Custom PC Board Greenhouse

We have found in the practice of greenhouses for many years that the reduction of the light transmittance of PC sunlight panels is often not the main cause of insufficient light transmission in greenhouses. The dew and dust accumulation in hollow PC sunlight panels is the "culprit". . In the construction and installation of greenhouses, it is often impossible to completely guarantee that the hollow PC sunlight panels are tightly sealed. The air around the greenhouses will enter the middle gap of the hollow PC sunlight panels at any time. After the humid air containing moisture enters the middle gap of the PC sunlight panels, Because the sealing of the PC sunlight panel caused great difficulty in its discharge, this easy-to-access structure structure made a large amount of water vapor accumulate in the intermediate space of the PC sunlight panel.

Moreover, due to air pollution, the wet air also contains a large amount of dust and dust, which will continue to accumulate in the hollow wall of the PC solar panel, eventually causing the dust pollution to cause a sharp decline in the transmittance of the PC solar panel material. The areas with more serious air pollution, the greater the decline in the light transmittance of the greenhouse, eventually resulting in the PC sunlight panel has not yet reached its strength and life, but the light transmission performance is difficult to meet the actual greenhouse production needs.

This phenomenon is not individual, but is relatively common. Therefore, when selecting light-transmitting materials in greenhouses, the understanding of PC solar panels should also fully consider the local climate characteristics and their possible consequences, and PC solar panels The cost is much higher than other materials, and it is conceivable that the economic burden caused by the replacement of the PC sunlight panel to the greenhouse producers.

3.PC sunlight panel greenhouse drip problem

In addition, the dripping property of the PC sunlight panel is also a major factor affecting the light transmission and performance of the greenhouse. Dripping property means that the water vapor in the greenhouse is large, and condensation water forms on the top or around the PC sunlight board and flows downward. Most brands of PC sunshine boards do not have dripping properties. Although some PC sunshine boards have anti-dripping properties at the beginning, the anti-dripping properties fail after a period of time and cannot be synchronized with the service life.

What Are The Main Types Of Greenhouses?

We are now almost inseparable from greenhouses for growing crops. Greenhouses can not only withstand natural disasters and drought and floods, but also cultivate early or postponed cultivation, extend the growth period of crops, and achieve the objectives of early maturity, late maturity, and increased and stable yield. Popular with farmers. Due to the different climates and applications in different places, the specifications of greenhouses are also different. China glass greenhouse manufacturer introduces the most common types of greenhouses to help you choose a suitable greenhouse.

1: plastic greenhouse

Large-scale multi-story plastic greenhouses are a type of greenhouse that has emerged and developed rapidly in recent decades. Compared with glass greenhouses, it has the advantages of light weight, small amount of framework materials, low shading rate of structural parts, low cost, and long service life. Its environmental regulation ability can basically reach the same level as glass greenhouses. The capacity is far higher than glass greenhouses worldwide, and has become the mainstream of modern greenhouse development.

2. Glasshouse

Agricultural glass greenhouse is a greenhouse with glass as a transparent covering material. In foundation design, in addition to meeting the strength requirements, it should also have sufficient stability and ability to resist uneven settlement. The foundation connected to the support between columns should also have sufficient horizontal force transmission and spatial stability.

The bottom of the greenhouse should be below the frozen soil layer. The heating greenhouse can consider the impact of heating on the freezing depth of the foundation according to the climate and soil conditions. Generally, the bottom of the foundation should be more than 0.5 meters below the outdoor ground, and the distance between the top of the foundation and the outdoor ground should be greater than 0.1 meters to prevent the foundation from being exposed and adversely affecting cultivation. Except for special requirements, the distance between the top surface of the greenhouse foundation and the indoor floor should be greater than 0.4 meters.

3. Solar greenhouse

The front slope is covered with heat insulation at night, and the east, west, and north sides are single-slope plastic greenhouses that are enclosing walls, collectively referred to as sunlight greenhouses. Its prototype is a single-slope glass greenhouse, and the front-slope light-transmissive covering material has been replaced by a plastic film to form an early sunlight greenhouse. Solar greenhouses are characterized by good thermal insulation, low investment, and energy conservation, and are very suitable for use in less developed rural areas of our country.

Single Span Greenhouse

4. Plastic greenhouse

The plastic greenhouse is an unheated, single-span arch roof structure greenhouse with plastic film as the covering material. The plastic greenhouse is easy to construct, easy to use, and requires less investment. It is a simple protected cultivation facility. With the development of the plastic industry, it has been widely adopted by countries around the world.

Plastic greenhouses are generally not heated indoors, relying on the greenhouse effect to accumulate heat. The lowest temperature is generally 1 ~ 2 ℃ higher than the outdoor temperature, and the average temperature is higher than 3 ~ 10 ℃.

The light transmittance of plastic greenhouses is generally 60% ~ 75%. In order to ensure the basic balance of the average light throughout the day, the layout of the greenhouse is mostly extended from north to south.

5.Single span greenhouse

Use circular arched shed: The basic requirements are a shed width of 8 meters, a shed length of 30 meters, a shoulder height of 1.8 meters, and a top height of 3 meters. Above 0.4m. The material is made of hot-dip galvanized steel, and 3 longitudinal tie bars are designed to enhance the wind and pressure resistance; 4 longitudinal film-pressing grooves (2 grooves on each side) are designed. The skirt film is 40cm high, and the upper side is fixed with a film pressing groove, and the lower side is buried in the soil to enhance wind resistance and sealing. The second pass is installed 140cm off the ground, and the roll film and the skirt film repeat 30cm. 6 vertical poles are installed at the ends; a film pressing rope is installed between each two arches to increase the wind resistance, and windproof braces are installed at the four corners of the shed to increase the stability of the shed. 1 座 double-sided sliding door is installed on the end face of each shed. The door size is 1.8 × 1.4m, and each seat has a total of 2

Greenhouses can make full use of solar energy, have a certain thermal insulation effect, and adjust the temperature and humidity in the sheds within a certain range through the roll film. The greenhouse is in the northern region: it mainly plays the role of heat preservation cultivation in early spring and late autumn. It can be 30 to 50 days earlier in spring and 20 to 25 days in autumn. Wintering cultivation cannot be performed. In the southern region: In addition to the heat preservation of vegetables and flowers and winter cultivation (leafy vegetables) in the winter and spring seasons, it can also be replaced with a awning for shading and cooling, rain, wind, and hail prevention in the summer and autumn.
