摘要: 食根动物是植物的主要危害者,植物与食根动物之间的相互作用一直备受关注。本文从食根动物与异质性土壤、根系的关系,以及食根动物对植物的影响等方面,探讨了食根动物与根系生物量的变化、再生能力、存活,植物化学物质与其他有机体之间的作用机理和食根动物对植物生理、种群动态、植物结构的影响。建议加强对植物控制食根动物取食时采取的对策、食根动物改变生态系统C、N循环的机制以及植物寄生性线虫存在的生态系统养分的动态变化等方面的研究。

Abstract: Root herbivore is of the main one that harms plant. The interrelations between root herbivore and plant have attracted extensive attention from scientists. In this paper, the effects of root herbivore on root biomass change, root regeneration and survival, plant physiology, dynamics of plant population, and plant structure, as well as the action mechanisms between plant semiochemicals and other organisms, were discussed, and some research fields that should be further strengthened, e.g., countermeasures of plant for esisting root herbivore, action mechanisms of root herbivore in changing ecosystem C and N cycling, and dynamic changes of ecosystem nutrients when parasitic nematodes exist, were suggested.
