噪声无处不在,它对人们的影响和危害人所共知。那么,噪声真是有百害而无一利吗?随着现代科技的发展,人们利用噪声也能造福人类。1噪声除草:不同植物对不同波段的噪声敏感程度不同。根据这个原理,科学家研制出了噪声除草器,它发出的噪声能够使草种子提前发芽,以便在种植农作物之前用药物除掉杂草。2噪声施肥:科学家通过实验发现,西红柿、土豆、芝麻、水稻等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。所以在农作物受噪声刺激的同时,进行施肥和喷洒营养物,这样十分有利于农作物生长,并能提高产量。
Noise is everywhere, and it is known to all people and their dangers. So, is noise really harmful and not beneficial? With the development of modern science and technology, people can use noise to benefit people. 1 Noise weeding: Different plants have different sensitivity to different bands of noise. Based on this principle, scientists have developed a noise weed killer, which emits noise that enables grass seeds to germinate early so that weeds can be removed with drugs before planting crops. 2 Noise fertilization: Scientists have found through experimentation that, when crops such as tomatoes, potatoes, sesame, and rice are stimulated by noise, the pores on the roots, stems, and leaves of the crops will expand to their maximum, and they will easily absorb fertilizer. Therefore, when crops are stimulated by noise, fertilizing and spraying nutrients are very beneficial to the growth of crops and can increase production.
