Some questions about the production of flowers in greenhouses greenhouses .

In summer, the main purpose of covering the shed is to cool and shade the shed.

In winter, the white cover is mainly to heat up the shed.

The main purpose of turning on the lights in the shed in spring is to increase the light and promote the differentiation of flower buds.

The ventilation fan of the greenhouse is mainly to reduce the humidity and ventilation inside.

SX Cover black sand cloth in midsummer is to shade the sun and heat of the plants and improve the survival rate of the plants; On the contrary, in winter, it is to keep the plants warm and grow at a constant temperature; Turn on the lights at night is photosynthesis, and the air fan is to let the indoor CO2 circulate and promote the balance of CO2 and large O2 with plant light

The greenhouse has been used in vegetable cultivation for decades, and has very rich planting experience, so there will be very professional builders to design it during construction. Greenhouses are now also used for a variety of purposes, such as flower cultivation, animal breeding, mushroom cultivation, etc.

So what kind of requirements does a flower greenhouse have when it is built?

First, the skeleton style of the main body of the greenhouse.

The main skeleton of the greenhouse is a layer of round arch added to the right of the bottom of the external round arch; Then an inner film is added around the perimeter of the greenhouse, so that the top and all sides of the greenhouse are covered with a double layer of film. The height of the columns of the traditional film multi-story greenhouse is generally about three meters, but the column height of our double-arch double-film greenhouse is increased to about five meters or six meters, which increases the height of the internal space. The interior is divided into two thermal insulation spaces by double membranes to enhance the thermal insulation performance of the greenhouse.

Second, the covering material of the greenhouse.

The outer membrane used in the double-arch double-membrane planting greenhouse is 15 filaments PO film, and the inner membrane uses 8 filaments PO membrane. The advantage of PO film is that it has a long service life, 15 filaments can be used for about five years, and 8 filaments can be used for about three years, and it has good light transmittance, heat preservation and anti-drip fog performance.

3. Double-arch double-membrane greenhouse supporting system.

This kind of greenhouse is equipped with external sunshade system, internal sunshade (heat preservation system), fan water curtain ventilation and cooling system, heating system, and water curtain outer film ventilation system. Due to the double-layer film covering on the top, the top of the greenhouse does not increase the top vent, which does not affect the normal growth needs of flowers and plants.

Fourth, the advantages of double-arch double-membrane greenhouse.

This kind of greenhouse can not only realize the large-scale production of flower planting, but also have good thermal insulation performance and reduce energy consumption in the northern region. This kind of greenhouse is economical and fast to build, so it can be put into production as soon as possible.

Management of overwintering flowers in flower greenhouses:

One is flowers that need to be wintered in low-temperature sheds. In the Yangtze River Basin, potted camellias, palm bamboos, rhododendrons, smiling flowers, vermilion red, etc., can safely overwinter in a dormant state as long as they are slightly protected at low temperatures. After entering the shed, you should pay attention to ventilation and cooling on sunny days, do not covet high temperatures, if you break the winter dormancy, it is easy to enter the growth state, and the cold resistance will be greatly reduced.

The second is to grow in the greenhouse, winter or early spring flowering flowers, such as primroses, melon leaf chrysanthemum, pampling flowers, calla lilies, cyclamen, etc., when cultivated in the shed, the temperature should be kept at 15-20 during the day, and the night should be covered with insulation at about 5, not less than 0.

The third is the need to overwinter in the high-temperature shed flowers, such as arrowroots, cacti, fortune trees, tropical orchids and other high-temperature flowers, in the Yangtze River basin by a single layer of plastic greenhouses wintering is not enough, but also must be supplemented by other measures. For example, add insulation materials such as straw and straw outside the greenhouse, or set a simple shed in the greenhouse to make a double-layer shed, or use electricity or stove heating. It can be reasonably selected according to the specific situation.

The common point between plant factories and greenhouses is that in addition to the differences in the facilities themselves, most of the agricultural equipment can be used both. Such as water purification machine, automatic irrigation machine, substrate treatment machine, hole tray pressing machine, semi-automatic grafting machine, seeding machinery, germination box, seedling room, seedling trolley, mobile trolley, seedling box, and so on. 2. From the perspective of planting varieties, greenhouses and all-artificial light plant factories can grow almost any kind of plants.

However, from the perspective of air management capabilities, the all-artificial light plant factory has advantages for the cultivation of a variety of neutral and negative plants. The greenhouse is superior in the cultivation of eggplant fruits, fruits, melons and fruits. The main difference is the cost of use, after all, one with free sunlight and one with electric energy.

3. The full artificial light plant factory needs to reduce the energy consumption, and the greenhouse needs to improve the product standardization. The two complement each other and integrate with each other. For example, the greenhouse lighting measures come from the precise lighting scheme of the all-artificial light plant factory, and the seedling cultivation of the all-artificial light plant factory is a kind of learning of the greenhouse operation model.

The intelligent Internet of Things in agriculture has become the standard configuration of plant factories and many mid-to-high-end greenhouses, which is part of smart agriculture, which is the proof of the integration of roads. 4. Greenhouse facilities belong to China, and the full artificial light plant factory is currently an important supplement, and the market position of the two is not equal. However, in terms of special area, special purpose and mobility, the all-artificial light plant factory has irreplaceable value and significance.

Hello dear, I am glad to answer for you: the common denominator of plant factories and greenhouses: 1

Relative to production, after the greenhouse intelligent control system is applied to the greenhouse production, the yield and quality are greatly improved than the artificially controlled greenhouse, for different planting varieties, the yield and quality are relatively different, and the production efficiency can be increased by more than 30% for high-grade cash crops. Relative to the operating cost of accounting, for a certain scale of planting enterprises, greatly reduce the labor cost, equipment investment and operation, can be completely calculated from the labor cost saved, the longer the use time, the labor cost saved is a huge profit. 02 In the greenhouse environment, a single greenhouse can use the Internet of Things technology to become a measurement and control area of the wireless sensor network, using different sensor nodes and nodes with simple actuators, such as fans, low-voltage motors, valves, etc. Thus obtaining the best conditions for plant growth.

03For agricultural parks with greenhouses, the Internet of Things can also realize automatic information detection and control. Equipped with wireless sensing nodes, each wireless sensing node can monitor a wide range of environmental parameters. By receiving the data sent by the wireless sensor convergence node, storing, displaying and data management, the acquisition, management, analysis and processing of all base test point information can be realized, and displayed to the users of each greenhouse in an intuitive chart and curve, and at the same time, various sound and light alarm information and SMS alarm information are provided according to the needs of planted plants, so as to realize intensive and networked remote management of greenhouses.

04In addition, the Internet of Things technology can be applied to different stages of greenhouse production. In the stage when the greenhouse is ready to be put into production, by arranging various sensors in the greenhouse, the internal environmental information of the greenhouse can be analyzed in real time, so as to better select varieties suitable for planting; In the production stage, practitioners can use the Internet of Things technology to collect temperature, humidity and other types of information in the greenhouse to achieve fine management, such as the time of opening and closing of the sunshade net, which can be sensed and controlled according to the temperature, light and other information in the greenhouse, and the starting time of the heating system can be adjusted according to the collected temperature information; After the product is harvested, the information collected by the Internet of Things can also be used to analyze the performance and environmental factors of plants at different stages, and feed back to the next round of production, so as to achieve more accurate management and obtain better products.

Summary. High-temperature greenhouse: Also known as a hot greenhouse. The indoor temperature is generally maintained at 18 30 °C,* for the cultivation of tropical species or for winter purposes.

1.What is a high-temperature greenhouse, an example of a high-temperature greenhouse in flowers-||The application of production.

High-temperature greenhouse: Also known as a hot greenhouse. The indoor temperature is generally maintained at 18 30 °C,* for the cultivation of tropical species or for winter purposes.

The greenhouse is the product of people's struggle with nature and consciously transforming nature; The cultivation of flowers in greenhouses is the result of people's growing demand for flowers. In modern horticultural production, greenhouses have become the basic equipment for the production of vegetables in winter. The characteristic of greenhouse flower cultivation is that its production process is basically carried out under human-controlled environmental conditions, and it is very little affected by changes in natural conditions, especially external meteorological conditions.

The use of greenhouses with good performance and complete supporting facilities can maintain a good microclimate inside the greenhouse and adjust the environmental conditions suitable for flower growth through manual adjustment.
