Ding Xuecheng looked at the "stones" in the flower pot, thought for a while, and said: "I think this observation activity will last for a long time, you see, those 'stones' have not bloomed yet, and I don't know how long it will take for it to bloom." We will record it once and then divide into two groups, one group to stay and observe, and one group to visit; When the observer notices a change, they call another group over and rotate it every half hour. Who is in my group? ”

Kiki and Yeon-yeon looked at each other and didn't say a word.

Ding Xuecheng was extremely depressed, and the two little girls obviously wanted to go with Binbin to gain knowledge, so they waved their small hands: "You all go for a while, just watch, there is no need for multiple people." ”

Seeing Binbin's fat face almost unable to stop laughing, Ding Xuecheng regretted in his heart: "This is the importance of knowledge, little sisters like knowledgeable little doctors, I must get an Internet device as soon as possible - a smart phone!" ”

The old god was there, and he spoke leisurely: "This thing is called Shengshi Flower, which is native to the extremely arid and rainless desert gravel areas in southern and southwestern Africa, and is commonly found in rock bed crevices and gravel, and can be cultivated in many places in the world. The shape of the raw stone flower is peculiar, the shape is like a colored stone, the color is rich, petite and exquisite, the raw stone flower is like a pebble and has life, and enjoys the reputation of 'living stone'. Grow raw stone flowers in small pots, and display them on windowsills, balconies, etc., which are naturally chic and interesting, and there are many enthusiasts who specialize in collecting and cultivating such plants. ”

Binbin's words frightened everyone present, the two little girls blinked their big eyes, looking like they were looking up at the mountains, Ding Xuecheng shouted in his heart: "Why not me?" ”

"Binbin, your knowledge is so rich, but what you are talking about is knowledge in books, not a substitute for observation! It can't be recorded either. Ding Xuecheng is still "arguing on reason".

"Mmmm, yes, what you said wasn't something you could have observed."

"Bobo's words make sense, and we're going to record what we've observed."

Bin Bin was deflated and indignant: "Then what do you say about recording?" ”

"Binbin, there is still one thing worth recording in the passage you just said, that is, the name of this 'stone' is raw stone flower. Yeon-yeon, let's record! ”

"1. The shape of the raw stone flower is peculiar, the shape is like a colored stone, like a pebble and has life. The raw stone flower plant has white, gray, green, brown and other colors, and has a hypertrophy of the raw fleshy leaves, and there is a crack between the two fleshy leaves. ”

"Do you have anything to add?"

Binbin: "Hmph, that's not what I just said! ”

Kiki: "I would like to add that the leaves are fleshy and hypertrophic, and the two pairs of leaves join together to form an inverted cone. There are many varieties and each has its own characteristics. ”

"Well, good! Is there anything else to add? Ding Xuecheng paused for a while, saw that everyone didn't mean to speak, and then said: "If not, I will stay and continue to observe, and you will go around for a while." ”

When the three men heard this, they left happily.

Ding Xuecheng was depressed, so he had to take a magnifying glass to check the stone flowers one by one.

He circled around the stone flower pots, thought about it left and right, and suddenly thought of the "taking pictures" and "videography" services that Bei Bei had originally said, and hurriedly called Bei Bei.

"Beibei, from now on, take a picture of the whole process of the stone flower's flowering, and then make a quick shot of about 1 minute, okay?"

"Yes, 5 points."

"It's only 2 points to rent a magnifying glass, why do you need 5 points for a camera?"

"Photography requires energy, and post-production, 5 points is not much."

"Well, well, let's go!"

The courtyard is not big, and they have not gone far. The voice of the polite "commentator" came from time to time, mixed with a lot of exclamations, which caused Ding Xuecheng's stomach to surge.

"This is hibiscus, this is camellia,...... Crape myrtle, Milan, osmanthus, plum ......"

"There will be peculiar smells and toxic and harmful gases in the decoration of new houses, and it is best to put a few pots of green bonsai with fruit plants after the house decoration is completed. Fruits are the best deodorant, such as pears, oranges, melons, small pumpkins, etc. Putting a bonsai with fruit in a new house is not only environmentally friendly, fragrant and natural, but also good for health. If you want to get rid of the pungent smell of your new home as soon as possible, you can use a light to illuminate the plants. Once the plant is irradiated with light, its vitality is particularly vigorous, and its photosynthesis is strengthened, and the oxygen released is several times more than that under the condition of no light irradiation. Aloe vera, spider plant, tiger tail orchid, one-leaf orchid, monstera, natural scavenger. Studies have shown that aloe vera, tiger tail and spider plant have a super ability to absorb formaldehyde, a harmful gas in the room. Evergreen iron tree, chrysanthemum, kumquat, pomegranate, purple jasmine, half lotus, yueji, camellia, Milan, daisy, plum, marigold, can absorb harmful gases emitted by household appliances and plastic products. ”

"Nowadays, many families like to place foliage plants, which are mainly divided into woody foliage, herbaceous foliage, hanging pots and ferns. Although flowers and plants are good, you should also be careful not to put too much in the bedroom. Because green plants will inhale oxygen and excrete carbon dioxide like people in the case of insufficient light, if the carbon dioxide concentration is too high due to poor air circulation, it will affect human health. ”

"Roses, osmanthus, violets, jasmine, lemons, roses, caryophyllus, lily of the valley, crape myrtle, these aromatic flowers produce volatile oils that have a significant bactericidal effect. Plants such as crape myrtle, jasmine, and lemon can kill native bacteria, such as diphtheria and dysentery, within 5 minutes. The fragrance of jasmine, rose, caryophyllus, lily of the valley, violet, rose, osmanthus and other plants has a significant inhibitory effect on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus and staphylococcus. ”

"Budax piran, saxi-tail, agave, as well as brown hairy palms, dwarf orchids, striped cabbage, hypertrophic sedum, cultivated pineapples, these plants purify the air at night. Two pots of these plants, such as pineapples, in a 10-square-metre room can absorb the carbon dioxide that a person excretes at night. ”

"Cactus, Arrow Lotus, Cactus Finger, Measuring Ruler, Epiphany, these plants can increase negative ions. When a TV or computer is turned on in the room, the negative oxygen ions will decrease rapidly. The stomata on the fleshy stems of these plants close during the day and open at night, absorbing carbon dioxide and releasing oxygen, increasing the concentration of negative ions in the indoor air. ”

"The cilia of orchids, osmanthus, plum, taro, and red laurel can absorb floating particles and soot in the air. Lilacs, jasmine, roses, violets, chrysanthemums, peppermint, these plants are relaxing and good for sleep. ”

"In addition, plants that are too strong and harsh, have a peculiar smell or have a strong fragrance should not be placed indoors. Such as: oleander, goldenrod, goldenrod (mandala flower). These flowers and plants are poisonous and not good for human health. The fragrance of nightshade has a strong stimulating effect on people's sense of smell, and a large amount of exhaust gas will be discharged at night, which is not good for the human body. The stems and leaves of evergreen contain dumb lollicase enzyme and calcium oxalate, which can cause itching when touched on the skin, and if eaten by mistake, it can also cause poisoning. Other plants, such as tulips, contain toxic bases; Mimosa, which can cause hair loss with regular contact; Daffodils, contact with the leaves and sap of flowers, can cause redness and swelling of the skin. ”

Therefore, the use of flowers and plants to purify the indoor environment should pay attention to the following three points: 1. Avoid fragrance: Some flowers and plants are too strong, which will make people uncomfortable and even produce adverse reactions, such as nightshade, tulips, five-color plums, etc. 2. Avoid allergies: Some flowers can cause allergic reactions. Like Yueji, jade cloves, five-color plums, hydrangeas, geraniums, bauhinia, etc., people touch and touch them, which often cause skin allergies, and even red rashes, which are unbearable. 3. Avoid poison: Some ornamental flowers and plants are toxic, and they should be placed with attention, such as mimosa, poinsettia, oleander, yellow rhododendron and champion red. ”

"Wow, how do you know so much?"

"yes, that's amazing!"

Ding Xuecheng's eyes straightened: "This kid's mental power may be higher than me, and I remember so much information!" His house can't be planted in a flower garden, right? ”
