The northern greenhouse is planted all year round

The northern greenhouse is planted all year round, and the north is planted according to the cold and warm climate all year round.

Crops grown in vegetable greenhouses all year round.

1. January: The solar terms are small cold and big cold.

1. Discharge air and humidity in the solar greenhouse for a short time at noon, use dust agents and smoke agents to control pests and diseases, and try not to use spray drugs to avoid increasing humidity.

2. Strengthen the greenhouse, pick up the snow in time on snowy days, otherwise the snow is too thick and may bend the greenhouse skeleton, and pay attention to temporary heating measures when the indoor temperature is lower than 6.

3. Cultivate tomatoes, eggplants and pepper seedlings planted in the open field in early spring in the greenhouse.

4. Cultivate spring cabbage and early cabbage flower seedlings in the greenhouse, and the varieties can choose Chungan 45, Chunlan, etc.

5. Multi-layer covering the autumn peppers, tomatoes, etc. in the greenhouse, hurry up the seedlings and prepare for the next stubble? Vegetable seed sowing and seedling planting.

6. Use a nutrient bowl to cultivate cucumber seedlings for spring greenhouses, and the variety can be Luyou 403.

2. February: The solar terms are the beginning of spring and rain.

1. Tomatoes, eggplants, peppers, loofahs, bitter gourds, and zucchini began to be planted in early spring in the solar greenhouse, and cabbage and cauliflower planted in greenhouses and middle sheds were planted.

2. Cut the spring black potatoes into pieces to promote germination, and cover the ground with mulch in late February.

3. Cucumbers cultivated in the middle shed are raised in early February in the heat preservation of the yang furrow.

4. Early-maturing watermelons in greenhouses begin to raise seedlings.

5. In late February, the greenhouses and the middle shed double-film covered racks kidney beans, cowpeas, and spring radishes began to broadcast live.

The nightshade vegetable seedlings cultivated under the protection condition of month-January should be divided in time at the two-leaf and one-heart stage, and the seedlings can be divided into nutrient bowls or nutrient clods.

March and March: The solar term is the sting and the spring equinox.

1. Vegetables entering the harvest period in the solar greenhouse should pay attention to top dressing, watering, and pest control.

2. The zucchini in the arch shed is raised in a nutrient bowl at the beginning of the month, and planted in the arch shed at the end of the month.

3. Three-layer covering

The northern winter greenhouse is in need of heating, agricultural greenhouse finned tube radiator is one of the many radiators selected in the modern greenhouse industry, it can not only bring temperature increase and warmth to the greenhouse in the cold winter, but also bring a certain amount of moisture to the animals and plants in the greenhouse, so that the growth environment of animals and plants in the shed will become more reasonable.

Finned tube radiator.

The finned tube radiator of agricultural greenhouse is made of large-diameter steel pipe, and the heat transfer medium that can be installed inside the large-diameter steel pipe will be more, and the heat transfer medium will be more, so when the radiator stops working, the internal medium will also have a certain temperature, because the medium is enough, so it needs to be cooled for a longer time. <>

Finned tube radiator.

Agricultural greenhouse finned tube radiator does not need 24-hour uninterrupted heating, so it is very suitable to use agricultural greenhouse finned tube radiator as heating equipment, agricultural greenhouse finned tube radiator is suitable for intermittent heating heating system, then the greenhouse is intermittent heating, so there will be more users choose finned tube radiator as the heating equipment of greenhouse. <>

Finned tube radiator.

Yes, you can use the land**and air**. It can also be warmed with fire.

When it is not produced, it is not needed, and even the shed must be opened to make the soil freeze-thaw process.

Yes, or they'll all freeze to death.

There are more crops that can be planted in greenhouses in summer, such as tomatoes, cucumbers, and water spinach.

Tomato cultivation techniques.

Plot selection. You should choose deep soil, good drainage and irrigation, good ventilation and ventilation, and do not plant nightshade vegetables within 2 to 3 years, and do not choose areas without irrigation facilities for cultivation.

Breed selection. Choose varieties that are disease-resistant, high-quality, high-yield, resistant to storage and transportation, have good commerciality, and are suitable for market demand, such as Jintiewang.

Sowing seeds and raising seedlings. Sowing time in early March to early April is appropriate, according to the actual local situation reasonable arrangement of sowing time, the use of fertilizer balls for mulch film and small arch shed seedlings, and with the well-rotted farmhouse fertilizer mix evenly after pinching into a fertilizer ball of about 5 cm, and put a seed, evenly arranged with nutrient soil.

Mulching, while applying a runny stool water, cover with mulch. Finally, it was covered with a small arch that was 8 meters wide and 8 meters long.

When there are 3** leaves growing, it is necessary to remove the film in time to ventilate and cool down, and carry out seedling training, a week later.

Colonization is carried out again.

Colonization management. Soil preparation and application of base fertilizer: 15 to 20 days before planting, apply 7 to 8 square meters of well-rotted high-quality circle fertilizer per mu, or 5 to 6 square meters of livestock and poultry will be stacked and fermented with the same amount of crop straw and then applied 100 to 150 kg of rotted cake fertilizer, using east-west high ridges.

If the greenhouse is cultivated 20 days before planting, the greenhouse is covered with film, and after the film is buckled, the bottom water is filled with ditching to irrigate the soil.

Planting method and density: plant spacing is kept at 50 to 60 cm, row spacing is kept at meters to meters, and 2000 tomato seedlings per mu are planted. Meanwhile, after 4 p.m. on a sunny day or on a cloudy day.

The planting is better, and the planting water should be watered thoroughly in time after planting, 3 to 5 days later.

Water the seedlings again 1 time.

Field management. Erection and pruning: when the tomato plant is about 30 cm high, it should be tied to the vine in time, and the "human" herringbone bracket is mostly used to erect the scaffold, and after the bracket is laid, the tomato trunk is fixed on the bracket with a plastic rope in the shape of an inverted figure 8, and a single stalk is used for pruning, each plant retains 5 to 6 spikes of flower spikes, and each spike retains 4 to 5 fruits.

In particular, it is necessary to remove the excess side branches in time and remove deformed fruits, diseased fruits, and excess fruits. In the later stage of growth, the lower old leaves and diseased leaves should be removed in time to reduce nutrient consumption and disease propagation, and enhance ventilation and light transmittance.

Cultivating weeding and cultivating soil: tomato seedlings can be cultivated and weeded after slowing seedlings, cultivating must be shallow and not hurt the roots, at the same time, remember that the tomato should be cultivated 2 to 3 times during the whole growth period.

Fertilizer and water management. Drip irrigation or dark irrigation should be used for watering, and the seedlings should be watered in time after planting, and the seedlings should be watered slowly after 3 to 5 days. The relative moisture of the soil is maintained at 60 to 70 percent in spring and 75 to 85 percent in summer and autumn.

Top dressing in time according to the length of the growing season and growth conditions. After deducting the basal fertilizer part, it is applied with water several times. It is worth noting that it is necessary to resolutely put an end to the use of organic fertilizers that have not been harmlessly treated, and it is advisable to use oil cakes and various biological fertilizers.

The summer greenhouse is suitable for growing tomatoes, cucumbers, water spinach, greens, etc., as well as radishes, green beans, okra and other crops. In summer, the temperature is high, and the greenhouse construction should choose a place with sufficient water source and convenient transportation, and choose sunscreen and high temperature resistance for the mulch film.

Greenhouses are mainly used to grow off-season vegetables, which can alleviate the shortage of the market and obtain higher economic benefits. The vegetables commonly used in greenhouse cultivation mainly include: cucumbers, beans, tomatoes, green peppers, leeks, chrysanthemum, radish, cabbage, cabbage, okra, etc.

If you sow seeds in summer, generally speaking, there are only chicken hairy vegetables and small green vegetables, so the production rate is very fast, the time is very short, and there is a shade net on the top of the head to prevent insects.

You can have some Asian stuff at noon and it's a very tasty kind that you can plant and try.

In the greenhouse, you can grow some watermelons, cucumbers, tomatoes in the summer.
