氮磷钾营养影响植物根部病害的研究进展

Research advances in the effects of nitrogen,phosphorus and potassium nutrition on root diseases of plants

氮、磷、钾是植物生长发育必需的三大营养元素,植物主要通过根系从土壤吸收营养。营养元素缺乏或不合理施肥等会导致植物根部病害的发生,影响植物的养分吸收,从而使植物生长受阻,产量降低。本文从氮、磷、钾这三种元素单独对植物根部病害的影响、三种元素交互对植物根部病害的影响,以及其影响病害发生的机理方面,总结了氮磷钾营养影响植物根部病害的研究进展,以期从调控营养元素含量和比例角度,为植物根部病害的有效防控提供思路,并为养分高效利用和减轻环境污染提供理论依据。

Nitrogen,phosphorus and potassium are three essential nutrients for plant growth and development.Plants mainly absorb nutrients from the soil through roots.The lack of nutrients or unreasonable fertilization will lead to the occurrence of plant root diseases,and affect the nutrient absorption of plants,thus hindering plant growth and reducing yield.In this paper,the effects of nitrogen,phosphorus and potassium on plant root diseases,the interaction of three nutrients on plant root diseases,and the mechanism of their effects on plant root diseases were summarized.This review provide ideas and methods for the effective prevention and control of plant root diseases from the perspective of regulating nutrients,and provide a theoretical basis for efficient utilization of nutrients and reducing environmental pollution.
