Scientists Say Plants“Scream”When Stressed科學(xué)家們說植物在有壓力時(shí)會(huì)野尖叫冶

Plant lovers believe that talking to plants helps them grow. Scientists havediscovered there could be some truth to it. Researchers have discovered that plants emit1 sounds when they are stressed. The noises are similar to a human cry orscream. The scientists believe the sounds are specific2 enough for us to be able tointerpret3 them and to attend to their needs. Unfortunately， plant sounds are at toohigh a frequency4 for the human ear to pick up.

Each plant and each type of stress is associated with a specific sound. Whilethe human ear cannot pick them up， the sounds emitted by plants can be heard bybats， mice， and insects. Interpreting these sounds could help us understand whencrops are dehydrated5. Farmers could water their crops more efficiently， and thussave water.

植物愛好者相信與植物交談?dòng)兄谒鼈兊纳L?？茖W(xué)家們發(fā)現(xiàn)，這可能有一定的道理。研究人員發(fā)現(xiàn)，植物在有壓力時(shí)會(huì)發(fā)出聲音。這種聲音類似于人類的哭喊或尖叫。科學(xué)家們相信這些聲音足夠獨(dú)特，我們能夠解讀它們并關(guān)注它們的需求。不幸的是，植物的聲音頻率太高，人耳無法捕捉。

每種植物和每種類型的壓力都與一種特定的聲音有關(guān)。雖然人耳聽不到，但蝙蝠、老鼠和昆蟲都能聽到植物發(fā)出的聲音。解讀這些聲音可以幫助我們了解作物何時(shí)脫水了。農(nóng)民可以更有效地澆灌作物，從而節(jié)約用水。
