据测定,一个成年人每天大约吸入0.75公升氧气,呼出1公升二氧化碳,而1公顷阔叶林在生长季节每天可消耗1吨二氧化碳,产生0.73吨氧气。全世界的绿色植物每天大约释放5万吨氧气,故有“天然制氧机”的说法。绿色植物还有着分泌杀菌素的本领,因此,被誉为“义务卫生防疫员”。实验证实,地榆根的分泌物可在1分钟内将伤寒、痢疾等病菌杀死;松树的分泌物可杀死白喉、结核等病菌;柏、樟、杉、槐等许多林木的分泌物都有较强的杀菌作用。这些杀菌素
It has been determined that an adult inhales about 0.75 liters of oxygen per day and exhales 1 liter of carbon dioxide, while a 1-hectare broad-leaved forest consumes 1 tonne of carbon dioxide per day during the growing season, producing 0.73 tons of oxygen. Green plants around the world release about 50,000 tons of oxygen a day, it is “natural oxygen machine ” argument. Green plants also have the ability to secrete bacteriocin, therefore, known as “voluntary health and epidemic prevention member ”. Experiments confirmed that the root of Ulna root discharge can be within 1 minute typhoid, dysentery and other germs to kill; pine secretion can kill diphtheria, tuberculosis and other germs; cypress, camphor, fir, Sophora and many other forest secretions are Has a strong bactericidal effect. These bacteriocins
