谁都知道,噪声对于人体健康极为有害。但不少科学家改变了固有观念,利用噪声来为人类生活服务,并已取得可观的效果。噪声熟果美国科学家发现有些农作物在受到某种噪声的刺激时,其茎、叶表面的气孔张开,便于吸收营养物质。科学家曾对西红柿进行了30多次实验,他们用100 dB的尖锐汽笛声作噪声源,同时施以肥料和微量元素。结果,西红柿的产量提高了数倍,而且果实比一般的要大30％。 Everyone knows that noise is extremely harmful to human health. However, many scientists have changed their inherent ideas and used noise to serve human life and have achieved considerable results. Noise Mature Fruits American scientists discovered that when some crops are stimulated by some kind of noise, their stomata on the surface of stems and leaves are open to facilitate the absorption of nutrients. Scientists have conducted more than 30 experiments on tomatoes. They used 100 dB of sharp whistle as a noise source, while applying fertilizer and trace elements. As a result, the yield of tomatoes increased several times, and the fruit was 30% larger than the average.
