绞杀现象是植物之间相互作用的一种很残酷的现象，近乎于动物界的弱肉强食，常见于榕属植物的群落中。这类植物依附在被绞杀植物上生长，长出很多气生根，这些气生根沿着寄主植物的树干不断向下延伸，插入土壤中，并逐渐增粗分枝，不断交叉、融合，逐渐将寄主树木网状包裹住，拼命抢夺寄主植物的养分和阳光。最后寄主植物由于营养亏缺不堪重负，几乎无一幸免都要死亡。 Strangulation is a very cruel phenomenon among plants, which is similar to the law of jungle in the animal kingdom. It is common in the community of Ficus. Attached to the strangled plants, these plants grow a lot of aerial roots, which extend continuously down the trunk of the host plant, insert into the soil, and gradually grow thick branches, constantly cross and merge, then gradually wrap the host trees in a network, and desperately compete for the nutrients and sunlight of the host plant. In the end, almost all the host plants die because of insufficient nutrition.
