树木为何会相互“礼让”？（把自然讲给你听）

Group 1 - The phenomenon of "crown shyness" is observed in the forests of Yunnan Ailao Mountain, where tree crowns maintain distance from each other to avoid overlapping and maximize sunlight exposure [1][2] - Trees exhibit a behavior of mutual "deference" to protect themselves from physical damage caused by crown collisions, which can lead to wear and vulnerability to pests [2] - The distance between trees not only aids in self-protection but also enhances their ability to perform photosynthesis by reducing mutual shading [2] Group 2 - Research indicates that trees communicate chemically with neighboring trees, prompting them to adjust their growth space when they come too close [2] - The forest ecosystem is characterized by a balance of competition and cooperation, contributing to a stable and rich ecological system with diverse plant structures [2]
