Expert: fragrant plants can repel mosquitoes, not the ones with strong taste

In summer, the weather is fresh and convenient to travel, but every summer, it is a season of mosquito infestation, not only buzzing, affecting people's rest, but also spreading infectious diseases People used to go to the supermarket to buy some mosquito repellent products in the summer, such as mosquito repellent spray, mosquito repellent incense, and some simple mosquito repellent The main ingredients of mosquito repellent incense and all kinds of mosquito repellent products are chemical elements, which are harmful to human body to a certain extent Therefore, many families, especially those with babies and mothers, are increasingly afraid to use such mosquito repellent products Are there non-toxic, pollution-free and pollution-free "three no products" that can replace mosquito repellent incense? One day, Ms Zhang and her daughter, who lives in Hunnan New District, went to Shenyang flower, bird and fish market and saw many businesses hang environmental protection and mosquito repellent labels on some plants, such as fragrant wood and pitcher grass Using green plants to repel mosquitoes is a good way Is it really effective? Zheng, a horticultural and ornamental teacher at Shenyang Agricultural University, said that some plants can really repel mosquitoes by emitting odor This kind of plants are usually called fragrant plants, and fragrant wood is just one of them "In fact, as long as the plant can emit a clear fragrance, or a slightly irritating smell, it can repel mosquitoes, Artemisia can also." Pitcher is a kind of insectivorous plant, which absorbs nutrients by catching insects The bottom layer of the "cloth bag" of pitcher grass will secrete a sweet liquid, which will attract insects to fly into it, and then slowly digest them However, Zheng said that although pitcher grass eats mosquitoes, its "food intake" is very limited, and it can not eat several mosquitoes a day Therefore, it only works in theory, but not in practice Zheng also said that if aromatic plants are placed in the home, the elderly and children should be careful not to choose plants with too much fragrance or too much pollen, otherwise the elderly and children are prone to allergic symptoms 000000; height: 20px; line height: 20px; font size: 12px; display: inline block; }.turn_page_box_content .tpb_right a:hover{background-color:#ffffff;text-decoration:none;border-color:#ff0000}.turn_page_box_content .tpb_right a.cur{font-weight:bold;padding:0 6px 0;border:1px solid #ed120a;background-color:#ed120a;color:#fff}.turn_page_box_content .tpb_right a.cur:hover{background-color:#ed120a}.turn_page_box_content .tpb_right a.tpb_btn_previous, .turn_page_box_content .tpb_right a.tpb_btn_next{padding-left:6px;padding-right:6px}.turn_page_box_content .tpb_right a{margin-right:6px;}
