Market visits
A variety of mosquito repellent plants are hot Selling Someone bought 20 pots and circled the room
The reporter visited the Xi'an Road Flower and Bird Market, and after entering the summer, mosquito repellent grass is a hot commodity. Mr. Xu, the owner of the flower shop, said that there are many kinds of mosquito repellent plants sold on the market, including rosemary, mint, marigold and so on. This type of plant generally has a strong aroma, and mosquitoes dare not come close after smelling, so they have a mosquito repellent effect. "There are also physical mosquito repellents, such as Nepenthes nepenthes." Mr. Xu smiled: "But we basically do not sell carnivorous plants offline, and we shop more online."
There is also a kind of mosquito repellent grass, Chinese name is called mosquito repellent vanilla, which is also a variety that is more traded. This plant is a genus of geraniums, scientific name is geranium (the following mosquito repellent grass refers to geranium). This is a synthetic variety that geneticists have bred by combining genes from citronella forage with chromosomes of geranium. Lemongrass itself has a mosquito repellent effect, so geranium also inherits this characteristic, emitting a strong lemon aroma and becoming a mosquito repellent plant.
"As long as we come to ask the guests of the mosquito repellent grass, we will first recommend the geranium." Mr. Xu introduced that the current price of a pot on the market is 10-20 yuan, depending on how many plants it has planted in a pot. There was once an aunt who bought a whole twenty pots and wanted to circle the room. "This mosquito repellent grass is definitely useful, and it will bloom small pink flowers, which is very popular with customers." Mr. Xu said.
Citizen reaction
Mosquito repellent grass is still bitten by mosquitoes in the corner The viewing effect is good but not very easy to raise
In the eyes of citizen Ms. Shi, mosquito repellent grass does not have such obvious effects. "I saw an advertisement for mosquito repellent grass on the Internet before, so I put two pots on the balcony of my home, and I didn't expect to die in two weeks." Ms. Shi is a regular visitor to the florist, and her home is full of flowers and plants. "I don't know how effective the mosquito repellent grass is, but it's really not easy to keep, even if it is watered regularly, I won't try it again."
It is understood that the reason why mosquito repellent grass can repel mosquitoes is mainly because of its smell, and the rich lemon aroma of the leaves makes the surrounding mosquitoes dare not come closer. The aroma coverage of a pot of mosquito repellent grass of a normal plant is only about two meters, and if it is placed in the corner of the room, the mosquito repellent effect is not obvious. Mr. Yu, a citizen, said: "I once went to a friend's house, and there were several pots of lush mosquito repellent grass on the flower rack of his house, and one afternoon, I still had two bags on my arm."
Mosquito repellent grass itself is an ornamental geranium, the flowers are white and pale pink, and it is also loved by many citizens. In addition, as a vanilla plant, the aroma emitted can also make people feel comfortable. Ms. Cheng, who lives in Taiwei Garden, said: "I don't quite believe in its mosquito repellent effect, but I still have a pot at home. Being able to arouse a child's interest in nature is its greatest value to me. ”

point of view
Want to be effectively mosquito repellent
It also depends on cleaning up the stagnant water
Guo Zhinan, head of the disinfection vector section of the Xiamen Municipal Center for Disease Control and Prevention, believes that mosquito repellent grass has little effect and is not recommended for home use. He said: "Mosquito control is a systematic project, there is no so-called 'artifact', the most effective way is to clean up the stagnant water." Without standing water, there are no worms and germs, and there are naturally fewer mosquitoes. Compared with mosquito repellent plants, the gauze tent is a more effective anti-mosquito facility. ”
Tips
How to raise mosquito repellent grass?
Plants should not be too much
Plant enthusiast and florist Zhou Kun said: "The appropriate growth temperature of mosquito repellent grass is about 10-25 ° C, which is not a light-tolerant plant, especially in the summer to strengthen shade, home potted plants are more suitable for indoor breeding." Summer high temperature should be less watering, no fertilization, is conducive to the development of the root system, improve disease resistance. It is recommended to spray water mist on the leaves in an appropriate amount, which can promote the continuous release of citronellal substances, and the lemon aroma will be more sufficient. ”
In addition, it is best not to plant more than two mosquito repellent grasses in the same pot, because too high a density will make it difficult for the root system of the plant to develop, and the narrow growth space will directly lead to plant death. Moreover, the pot needs to be changed once a year, which can not only provide more adequate nutrients to the roots, but also clean up the waste accumulated in the old pot in time. When watering usually, pay attention to whether there is stagnant water at the bottom of the basin and drain it in time.
