How to grow vegetables in greenhouses in winter ,,,

Greenhouse vegetables winter planting heating equipment, greenhouse is a more common building in the north of the winter, its main role is to breed fresh vegetables, fruits, etc. for people in winter, then, people need heating equipment like air conditioning, floor heating and other types of heating equipment in the living room, the greenhouse industry is no exception, and also needs certain heating equipment to maintain the growth of vegetables.

Finned tube radiator.

Greenhouse radiators are often used in the light pipe radiator and finned tube radiator, the heat dissipation efficiency of both is better than the general radiator, but the heating efficiency of the finned tube radiator is better than the light pipe radiator, as for the specific choice of what kind of heating equipment, the user needs to think carefully. <>

Finned tube radiator.

What the greenhouse radiator needs is to make the temperature in the greenhouse reach a certain constant temperature, which is the basis for the growth of vegetables and fruits, and a reasonable temperature is the prerequisite for its growth. The choice of greenhouse radiator must be cautious, because it is related to the benefits of the greenhouse users themselves. <>

In view of the impact that the recent weather may have on the fruits and vegetables of the facility, measures should be taken in time before the arrival of snowfall and cold wave weather, and various tasks such as "windproof, heat preservation, antifreeze, disease prevention, and increasing greenhouse light" should be taken. 1.Before the arrival of cloudy and snowy days, melons and fruits should be picked early, and new high-fat film + root spirit should be sprayed to prevent pathogen infection, so that nutrients can flow back to the root system, promote root growth, and enhance the ability of plants to resist adverse environments.

Watering and topdressing should be stopped in the greenhouse on cloudy days, so as not to cause crop roots and aggravate the occurrence of diseases. 2.In the case of even cloudy days, as long as the temperature is not very low, the grass should be properly uncovered and try to scatter light as much as possible.

At the same time, a reflective curtain can be hung at the back of the greenhouse to enhance light and temperature. 3.If the weather is clear after continuous snowfall, the cover cannot be completely removed, and it should be removed successively to prevent "flashing seedlings".

After peeling, it is necessary to pay attention to the changes of crops, and when wilting occurs, it is necessary to immediately cover the grass and spray a new high-fat film to shorten the seedling period. After the seedlings have recovered, the grass is removed, and this is repeated for two or three days, and then transferred to normal management. 4.

Pay attention to heat preservation and heat properly. Multi-layer covering and insulation, that is, covering double layers of grass outside the shed film; If the temperature in the shed is lower than the minimum temperature required for the crop, the room temperature can be appropriately increased by auxiliary heating, but the indoor temperature should not be raised too high to affect the normal development. 5.

Pay attention to windproofing. Before the arrival of windy weather, it is necessary to check the fixing of the plastic film, the laminating line or the pressing rod must be fixed firmly, and the straw must be covered and pressed tightly, and the damaged shed film must be repaired and perfected.

In winter, the varieties of vegetables planted in greenhouses include celery, coriander, leeks, fungus, spinach, lettuce, chives, chrysanthemum, etc., among which celery has strong cold resistance and is suitable for growing in fertile soil, coriander is a cold-resistant vegetable, and the growth temperature is about 12 degrees, while leeks do not have high light requirements, and are suitable for breeding in winter greenhouses.

1. Celery

Celery is suitable for planting in winter greenhouses, it has strong cold resistance, is one of the vegetables commonly eaten by Chinese, when planting celery, you need to choose varieties with strong insect resistance and high yield, and then soak celery seeds in salt water for 10 minutes to make them germinate quickly, and then you can sow celery seeds in the soil.

2. Coriander

Coriander is a cold-tolerant vegetable, it is suitable for growing in a low temperature environment, and it will grow poorly when the ambient temperature exceeds 20 degrees.

3. Leeks

Leeks are suitable for planting in winter greenhouses, it is a perennial root herbaceous plant, the stem height can reach 45 cm, when breeding leeks, it is necessary to ensure that the soil is moist, and the leeks can be regularly watered with water, so that the water content in the soil is kept between 80-92% to maintain the normal growth of leeks.

4. Fungus vegetables

The cold tolerance of fungus is strong, when planting fungus in the winter greenhouse, it is necessary to germinate its seeds first, because the seed coat of fungus is relatively hard and not easy to germinate, you can put the fungus seeds into 35 degrees Celsius warm water for 1-2 days, and then place them in a 30 degree environment for germination.
