The summer solstice today plants fight mosquitoes

Today is the summer solstice, but the citizens have felt the power of a hot summer day Long summer night, as fierce as the weather, there are also the "flying army" mosquitoes buzzing Mosquito repellent incense, mosquito repellent water, insecticide It looks powerful, but its chemical composition and pungent smell are always disturbing As a result, many citizens fell in love with various mosquito repellent plants So, can these plants with environmental protection signs really repel mosquitoes? In the Tiansheng flower and bird market, almost every flower garden door has all kinds of mosquito repellent grass "Natural non-toxic" and "green environmental protection" are the slogans that bosses like to put out most, aiming at the consumer psychology of environmental protection "There are many expectant mothers or babies at home who come to buy mosquito repellent plants." The owner of a flower garden said that the sale of mosquito repellent plants has been good recently Reporter in the market around, see the mosquito repellent plants mainly have mosquito repellent grass, mint, rosemary, they have a feature: will send out a relatively strong smell On the spot, I heard that three kinds of plants have their own characteristics: Mint has a special taste, a bit like gum, and a bit like toothpaste; mosquito repellent grass has a slightly lighter smell, with a bit of lemon; as for rosemary, it's a bit spicy, like the spice that will be used in a certain dish, but it's hard to describe the specific taste The price of these plants is very "civilian" For example, mint, rosemary and mosquito repellent grass are basically sold for about 10 yuan each basin, and it sounds very good to feed "Mint, water every three days, until it's fully watered, just raise it casually." The boss introduced the precautions for raising grass There is also a mosquito repellent plant in the market, but the way of mosquito repellent is different from the above three plants, that is, pitcher grass "I can really eat worms." The boss also turned over the cage and found that there were some small black worms sticking to it However, pitcher's "posture" is more suitable for hanging on the balcony of home than the front three kinds of plant feet The price is also relatively expensive, about 45 yuan per basin Since it is known as mosquito repellent plant, of course, it is to "do not see the advertisement, see the curative effect" "It's always useful." The boss always says he buys good things Yesterday, the reporter specially consulted Ni Sui, a professor in the school of life science and bioengineering of Ningbo University She said that the plant odor with mosquito repellent effect is its own characteristics, but the effect may not be as good as the business claims Plants have limited mosquito repellent distance If you put a basin in the living room, there may be no mosquitoes near within one or two meters around, but for the whole room, there is no such effect Ni Sui also said that although the irritant odor emitted by the mosquito repellent plants will not cause direct harm to the human body, it may feel like poor breath, dizziness and chest tightness after smelling for a long time She does not recommend that the public place it in the closed air-conditioned room The most suitable location should be a ventilated balcony or window, which can prevent outdoor mosquitoes from flying into the room Although the mosquito repellent effect of these plants remains to be tested, it does not prevent them from becoming consumers' favorite The owner of a flower garden said that peppermint is the best seller It can sell about 1000 pots in a summer.
