On Giving Gifts to Teachers on Teachers' Day

Buy some flowers or potted plants. The following is for reference.

What flowers and plants should be kept indoors? This is a problem that people are more concerned about.

Placing some anti-pollution flowers indoors can purify the air. For example, ivy can "eat" benzene, chlorophytum can "swallow" indoor carbon monoxide and formaldehyde, and bracts of Araceae can absorb benzene and trichloroethylene. 10 square meter room, if there is an anti-pollution plant, it will be of great benefit to air purification.

In modern houses built with reinforced concrete prefabricated panels, the air humidity is far below the normal standard, and a plant named Cyperus likes water, so potted Cyperus should be placed in a deep pool to turn a "desert" into an "oasis". Feeling depressed, the reason is not lack of oxygen indoors, but lack of negative oxygen ions. When there is a TV or computer in the room, negative oxygen ions will decrease rapidly. There are many flowers and plants that can be planted indoors that can produce negative oxygen ions-these flowers and plants are cypress, arborvitae and cedar.

If the room area is small, you might as well plant some lower plants, such as cactus. At present, spruce and other low conifers are popular in the west, which can make the room full of refreshing tree fragrance. Many flowers and plants suitable for indoor planting have sterilization function. If some potted oranges, rosemary, mahogany and chlorophytum are placed indoors, the bacteria and microorganisms in the air will be greatly reduced.

Some of the flowers mentioned above are easy to grow, which can be seen in the flower market generally, and the price is relatively low, which is very suitable for family planting.

Plants that can absorb toxic substances, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum, are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good absorbent of formaldehyde.

In addition, plants with air purification function also include:

Kidney fern, cyrtomium fortunei, Chinese rose, crape myrtle, clove, magnolia, osmanthus fragrans, clover, aloe, Commelina communis, auricularia fern, cactus, tiger orchid, agave, pineapple, cactus, arrow lotus, epiphyllum, gem flower, Sedum, Sedum purpurea, ivy, cycad and chrysanthemum.

Radiation-resistant ornamental plants

Some ornamental plants have the function of absorbing electromagnetic radiation. Placing these plants at home or office can effectively reduce the electromagnetic radiation pollution caused by various electrical and electronic products. These plants include: cactus, gem flower, Sedum and other succulents.

Insecticidal ornamental plants

Some plants have special fragrance or smell, which is harmless to people, while mosquitoes, cockroaches, flies and other pests will avoid it when they smell it. Some special scents or smells can also inhibit or kill bacteria and viruses. These factories include:

Tuberose, pyrethrum, wild chrysanthemum, mirabilis jalapa, lemon, crape myrtle, jasmine, orchid, clove, atractylodes rhizome, popcorn, dandelion, mint, etc.
