噪声,是一种声污染,一向为人们深恶痛绝。然而,随着科学技术的不断发展,人们发现,噪声也不那么可恶,只要合理利用,它们还能为我们造福。噪声施肥美国科学家丹卡尔森发现,某些农作物受到噪声刺激时,其根、茎、叶表面的小孔会扩张到最大限度,因而容易吸收肥料。他让试验田里的西红柿处在尖锐的汽笛声中三十多次,同时对这些西红柿施肥和喷洒营养物,结果竟结出700多个果实,而且比一般西红柿 Noise, is a kind of sound pollution, has always been abhorrence. However, with the continuous development of science and technology, people find that noise is not so damn good and they can be used for the benefit of us if they are used rationally. Noise Fertilization Dan Carlson found that when some crops are stimulated by noise, the pores on the roots, stems and leaves expand to their maximum extent and are therefore easily absorbed. He left the tomatoes in the experimental field in a sharp whistle for more than thirty times, fertilizing and spraying nutrients on these tomatoes at the same time, resulting in more than 700 fruits and more than the average tomatoes
