How to keep warm in the nursery flower greenhouse in winter?

If you want to keep warm in the nursery flower greenhouse in winter, I will recommend a finned tube radiator suitable for use in the greenhouse, the finned tube is the core element of the heat exchanger, and its quality directly affects the working performance of the heat exchanger. It makes use of the pressure resistance of steel pipes and the heat transfer performance of aluminum materials, and has the characteristics of compact structure, small unit volume and high heat exchange efficiency. The finned tube radiator has high efficiency, and the steel tube and fin are wound and welded in full contact in the process of fabrication, and its heat dissipation area is 8 times that of the plain tube, and its inner wall is smooth and the resistance of water flow is relatively small.

In the finned tube radiator (heat exchanger) series products, whether it is in the civil hot water heating system or from low-pressure steam heating to the larger heating and heat dissipation in the large industrial plant workshop, and then it is the industrial steam and heat transfer oil drying radiator. The finned tube radiator periphery is convection and sprayed plastic, which increases the decoration and treks the heat transfer power. (The outer cover is divided into type A, type B, type C, type D, type E, and type F).

Finned tube radiator.

Steel-aluminum composite finned tube radiator is widely used, mainly because of its large adaptation range, whether it is for the purpose of heating or cooling air, the temperature range of air can be from -30 -250, during which the contact thermal resistance of the heat exchange tube is almost zero. At the same time, it makes use of the pressure resistance of steel pipe and the efficient heat transfer performance of aluminum, the advantages of the two are combined, the heat transfer performance is excellent, temperature resistance, easy to clean, and not easy to scale and ash.

First, work the greenhouse film.

1.Before the cold air comes, the plastic film of the greenhouse should be carefully checked, and the holes and cracks should be repaired in time, and the membrane edge connected to the ground should be pressed with soil to prevent cold air from drilling into the shed.

2.Friends with conditions can use double film covering, and build another layer of film under the non-drip film, which can significantly increase the temperature in the shed.

3.Remove dust, dirt and snow from the greenhouse film in time to increase the light and increase the temperature of the shed.

Second, start from the external environment of the greenhouse.

1.The polyester aluminized film can be hung on the north side of the greenhouse to form a reflective curtain, thereby increasing the light in the shed and increasing the temperature of the shed.

2.Dig trenches around the greenhouse and fill in insulation materials such as horse manure, weeds, and straw to increase the ground temperature.

3.When the weather forecast is frosty, you can smoke outside the shed that night to drive away the cold, so that the temperature around the greenhouse will rise, and the temperature inside the shed can also increase accordingly.

4.The outer straw curtain is woven into a straw curtain with straw, which is covered outside the greenhouse at night (lifted during the day), which can not only slow down the heat dissipation in the shed, but also protect the frost from the shed film.

3. Manage the interior of the greenhouse.

1.Generally speaking, if it is cultivated on high ridges, it is covered with plastic film; If it is cultivated in a flat furrow, a small arch shed is erected. You can also dig a pool every few meters in the greenhouse, and lay a plastic film at the bottom of the pool, fill the pool with clean water, and then seal it with a transparent film, so that the water can absorb heat at noon and release heat at night for heating.

2.You can add a stove or turn on the heating in the shed, but pay attention to the installation of a chimney to remove the gas from the shed in time to prevent flower gas poisoning. At the same time, firewood and grass should not be burned in the shed, as the smoke can damage the flowers.

3.If the area of the greenhouse is relatively small, the bucket filled with hot water can be placed in the greenhouse during frost, because the hot water emits heat, the temperature in the greenhouse can rise, so as to play an anti-freezing role.

4.Irrigation before frost can be carried out to improve the soil and air humidity in the shed. Due to the large heat capacity of the water, even if the temperature outside the shed is below 0, the fruit and vegetable seedlings in the shed can grow normally.

5.When organic fertilizer is decomposed, it can not only provide nutrients for flowers, enhance the frost resistance of flowers, but also release heat, so fertilizer such as horse manure and broken grass can be applied in the shed. In addition, the grass ash is gray-black, with strong heat absorption ability, and can be scattered appropriately on the greenhouse ground.

Nursery winter seedling maintenance knowledge - fertilizer before winter should be based on farmhouse fertilizer and compound fertilizer, no or less nitrogen fertilizer. If excessive nitrogen fertilizer is applied, it will cause the seedling branches to grow vigorously, the degree of lignification is low, and the cold resistance is reduced. Fertilizer should be applied to the lateral roots of seedlings.

1. Paint the trunk white.

Taking advantage of the fine weather to coat the branches with a happy forest whitening agent can reduce the damage to the sunny side of the seedling due to the excessive temperature difference between day and night, and at the same time can also kill the overwintering germs and insect eggs.

2. The backbone "dresses".

For seedlings that are not cold-tolerant, the main stem and part of the main branches should be rolled dry with straw or wrapped with straw, so that the seedlings can wear "cotton clothes" before the arrival of winter to prevent frost damage.

3. Scrape the skin and apply medicine.

At the beginning of winter, the diseased skin and insect-eaten skin of the main trunk, large branches and branches of the seedlings should be scraped off as soon as possible, and burned or buried deep in a concentrated manner to eliminate the germs and eggs that overwinter in the bark. The depth of skin scraping should be slightly yellow-green in the cortex, and the callus cream should be applied to the wound to place the loss of water and nutrients and promote the early healing of the wound.

4. Set up obstacles to resist the wind.

In order to resist and mitigate the damage that cold and dry winds may cause to seedlings, a windproof wall should be erected in the upwind direction of the nursery before wintering. The height of the windbreak wall should be higher than the height of the tree. In addition, the windbreak wall should be fixed with wooden sticks, bamboo poles, etc., to prevent it from being blown down by strong winds.

5. Water control and anti-freezing.

After entering the winter, the water should be strictly controlled, and there is generally no need for watering except for special droughts. Because if the water content of the tree is too large, once it encounters low temperatures, the tree will freeze and expand, causing the bark to crack and cause the seedlings to die.

6. Spraying to eliminate damage.

After the seedlings fall leaves, they should be sprayed with 5 Baumé stone sulfur mixture and 200 times sodium pentachlorophenol solution to eliminate overwintering germs and insect eggs.

Nursery insulation is not as complicated as yours.

Insulating shed or insulating film, and then sprinkle charcoal or charcoal ash in the nursery.

If conditions permit, you can install a temperature-adjustable insulation shed.

I suggest that you install the "shed fresh brand" heating lamp to solve the problem of greenhouse insulation. Hope it helps.

In the cold winter, building a simple greenhouse can effectively keep the flowers and plants warm, windproof, rainproof, and cold, so that the plants can survive the winter safely.

Answering pro, flowers and plants like to grow in a relatively warm environment, and have a certain degree of cold tolerance. Since winter is a relatively low temperature season, it is important to take measures to keep warm. It is best to place it in a heated place indoors, or cover it with a layer of agricultural film to keep warm and avoid frost damage.

Winter flowers and plants are not cold tolerant, so they are placed in a heated sunny position indoors or covered with a layer of agricultural film to keep them warm. Stay in the sun every day, for example, for 9-11 hours. When the potting soil is dry, you can water, and if it is not dry, you don't need to water, and the water temperature should be almost the same as the soil temperature.

Flowers and plants need a certain amount of water to grow and flower, and in winter, the temperature is very low, and the water evaporation of potting soil is relatively slow, so be sure to water it in moderation. When the potting soil is dry, you can water it, and if it is not dry, you don't need to water it. There should be no stagnant water every time you water, and the water temperature should be almost the same as the soil temperature.

When I asked about greenery, how to keep warm.

Answer: Flowers and plants grow slowly in winter, so they can be pruned appropriately. For example, some diseased branches, cross branches, overlapping branches, long branches, and old yellow branches are cut off one by one, and the branches and leaves are found to be yellow and pested, so as to avoid nutrient consumption and maintain a certain permeability.

The most common way is to cover the insulation quilt.

1. Choose high-quality non-drip film, which should have high transparency, and will not produce dripping and fogging. Sunlight can penetrate well and increase the temperature in the shed.

2. In order to increase the temperature, cover the grass curtain at night. Insulate the greenhouse.

3. Adding reflectors in the shed can reflect the sunlight well, which also improves the temperature in the greenhouse.

4. Lay floor heating in the greenhouse. It can increase the temperature in the greenhouse and is suitable for the growth of flowers.

5. Heating facilities can be added to the greenhouse, which can effectively increase the temperature in the greenhouse.

6. The flowers in the greenhouse can be planted on ridges, and the mulch film of the black vibrato cover can be used, which can effectively absorb sunlight and increase the temperature of 4 to 5 degrees.

Flower greenhouses are insulated in winter, and greenhouse vegetables need heating equipment, which needs heating equipment to maintain the temperature in the shed and provide a reasonable growth environment for the plants in the shed. The light pipe radiator is a very favorite product for the greenhouse with reed pants, the special pipe radiator for the greenhouse has high pressure, suitable for all drinking water quality, no contact side branches to accompany the heat transfer coefficient of Qijian, and the heat dissipation function is good.

Optical pipe radiator.

The light pipe is a very popular heating equipment in the radiator market, mainly because it has the irreplaceable advantages of other radiators. The size and structure are varied, and the radiator itself can be processed into different specifications and models according to the different indoor actual environments such as different house structures and aspect ratios. <>

Energy saving, environmental protection, space saving, easy operation, investment saving and other characteristics are the considerations for plant heating. The heat dissipation mode of steel light pipe radiator is mainly convection. The appearance and inner cavity are clean, the heat dissipation performance is good, the pressure bearing capacity is high, the structure is simple, and the installation and maintenance are relatively simple.

The seamless steel pipes are used for connection, which is easy to operate and can provide sufficient heat supply.

Keeping flowers and keeping warm in winter is the key, and the following are two recommended heating and insulation products suitable for use in greenhouses.

One is the light pipe radiator: the greenhouse light pipe radiator mainly uses the limbs to maintain the stability of the temperature in the greenhouse, and the light pipe radiator can quickly raise the temperature to the set temperature for indoor heat dissipation after the equipment is turned on, and increase the indoor temperature in a short time, which is that the temperature in the greenhouse is in a constant temperature state, providing a good growth environment for the plants in the greenhouse.

Optical pipe radiator.

The light pipe radiator is a simple structure, excellent heat dissipation effect, corrosion resistance and pressure resistance, is a steam radiator series, the series of radiators can be based on people's actual needs and the size of the room area and the size of the steam pressure, temperature, after a comprehensive comparison of the model selection of the radiator, and then production.

Optical pipe radiator.

The second type is the finned tube radiator: the greenhouse finned tube radiator.

The heat in the large-diameter steel pipe is dissipated from the surface of the radiator through the circulation of the medium, and the cold air in the air is directly heated, and its heat dissipation can reach about twice that of the general steel radiator. The steel finned tube convection radiator is often used in some tall and large factories in Yijiayuan, and is installed in the heating system of the plant, which can not only play a role in improving the heat dissipation efficiency, but also extend the service life of the radiator system. The steel finned tube convection radiator is wear-resistant, durable, and long-lasting for heat dissipation.

Finned tube radiator.

The greenhouse finned tube radiator can be processed according to the actual use of different sizes of radiators, the length is from 1 meter to 20 meters long, and the number of internal pipe layers also needs to be designed according to the actual needs, and the reasonable structure is the basis for excellent heat dissipation effect. Greenhouse finned tube radiator is a kind of heating equipment used more in industrial workshops, and its pressure bearing capacity and heat dissipation performance are better than general heating equipment. Usually the area of the plant will not be less than a few hundred square meters, so its heat dissipation demand is very large, and the finned tube radiator for the workshop can meet its needs.

These two products have the characteristics of simple structure, large heat dissipation and low cost, in addition to the two products I recommend for you, the thermal insulation effect of the greenhouse should also be done, otherwise it is in vain to rely on the heat source heater to dissipate heat and the amount of heat can not be saved. Hope!

In winter, we must do a good job of thermal insulation measures, quickly move the flower friends and Shenhui plants indoors, and stabilize the indoor temperature above 10. In the northern region, flowers and plants can be covered with film to keep warm and cold. When watering, adjust the water temperature to be close to room temperature, and receive bright sunlight at noon, and use the temperature of natural light to keep warm.

Winter is the coldest season of the year, so you should immediately move flowers and plants indoors for maintenance. Most flowers and plants can tolerate temperatures above freezing, but in order to avoid frost damage, it is better to adjust the room temperature to more than 10. If you keep warm next to the hot air of the air conditioner or the warm boy, it may cause the flowers to wilt.

For example, in the northern region, the temperature is too low, so consider using a covering film to keep the cold cold. However, when covering the film, it is necessary to poke a few small holes in the film, otherwise the breeding potting soil will be impermeable, forming a closed environment, causing the wilting, lodging and death of flowers and plants.

Although the winter is cold and it is easier to form frost damage, it is not possible to completely leave water without watering, otherwise the flowers and plants will dry up. Every time you water, choose a warmer time at noon, and adjust the water temperature to close to room temperature before using the water quality for each watering.

Sunlight has its own warm temperature, but in winter there is less light and the intensity is weaker. In order for flowers and plants to enjoy sufficient photosynthesis and keep warm and cold, they should receive direct sunlight at noon. In long-term cloudy and rainy days, it can be artificially brightened to solve the light requirements.
