What are the precautions for greenhouse flower cultivation?

Greenhouse flowers refer to those plants that are more afraid of the cold and are not hardy. Once these plants come to the cold season, they need to move indoors or greenhouse to survive. Today, let's take a look at what conditions are needed for the cultivation of greenhouse flowers.

What are the characteristics of greenhouse flowers

Refers to flowers native to tropical, subtropical and warm areas of the south. Cultivation in cold areas of the north must be cultivated in a greenhouse or protected in a greenhouse in winter. It can be divided into the following categories:

1. Annual or biennial flowers. Such as Chrysanthemum morifolium, Baobao flower and so on.

two。 Perennial flowers. Such as African chrysanthemum, gentleman orchid and so on.

3. Flower bulbs. Such as cyclamen, Zhu Dinghong and so on.

4. Orchidaceae. According to its ecological habits, it can be divided into terrestrial orchids and epiphytic orchids.

5. Succulent plants: including cacti, sedum and other families.

6. Fern. According to the different ways of viewing, it can be divided into garden greening ferns, potted foliage ferns, hanging ferns and mountain bonsai ferns.

7. insectivorous plant. Such as pitcher plant, bottle grass and so on.

8. Plants of the family Pyraceae. Such as water tower flowers, wind pears and so on.

9. Brown paulownia plants. Such as sunflower, brown bamboo and other foliage flowers.

10. Flowers and trees include poinsettia, variegated trees and so on.

11. Aquatic flowers such as Wang lotus, tropical water lilies and so on.

What are the humidity requirements of greenhouse flowers

Generally speaking, flowers that require high temperature have relatively high requirements for air humidity. According to the temperature-loving habits of flowers, the relative humidity of flowers in high temperature depression room is between 80 and 90, that in medium temperature greenhouse is between 70 Pa and 80 Pa, that in low temperature greenhouse is between 60 Pa and 70 Pa, and that in cold room is about 60%.

The method of adjusting the temperature, in addition to considering its moisturizing performance in the design of the Ju room, if the humidity of the ancestral room is too high, you can open the window at any time to reduce the humidity of the room. If the humidity in the depression room is too low, you can often sprinkle some water on the floor of the greenhouse to improve the air humidity. In addition, conditional greenhouses can be equipped with power spraying equipment to adjust the humidity of the greenhouse at any time.

3. Arrangement of potted flowers in greenhouse

1. In a greenhouse, the illuminance decreases with the increase of the distance from the glass surface, so the flowers that like light should be placed in the front and middle of the greenhouse with plenty of light, close to the glass window and roof as close as possible, which is also the main reason for the application of grade stage to place potted flowers; shade-resistant and light-resistant flowers are placed in the back or semi-shade of the greenhouse.

two。 To keep the plants from shading each other or less, put the short plants in the front and the tall ones in the back. The temperature near the heat source is high, and the temperature changes greatly near the door because the door is often opened and closed. Warm-loving flowers should be placed near the heat source, and strong and cold-resistant flowers should be placed near the door and near the window.

3. Flowers have different requirements for light, temperature, humidity and other conditions at different stages of growth and development, so they should move their position or change the greenhouse accordingly. In order to speed up the speed of sowing and planting, flowers should be placed close to the heat source. After taking root and putting leaves, you need to move to a place with lower temperature and plenty of sunshine. Dormant plants do not have strict requirements for light and temperature, and can be placed in places with poor light and temperature conditions.

Greenhouse flowers related knowledge is introduced here, generally speaking, now the bedroom because of the development of science and technology can basically achieve the demand of constant temperature, so some greenhouse flower culture technology, can also be applied to indoor flower breeding.
