农药在植物中的内吸和传导行为与施药技术研究进展

Review on uptake and translocation behaviors of pesticides in plants and application technologies of pesticides

农药的施用方式和施用效果与其在植物中的内吸和传导行为密切相关。农药在植物表面和内部的内吸和传导行为,不仅与其自身理化性质有关,还受植物种类、生长期、生长条件及施药方式等因素的影响。研究农药在植物体内的内吸和传导行为及其影响因素,对于选择合适的施药技术及提高农药利用率具有重要的指导意义。本文综述了农药在植物体内的内吸和传导行为、传导方式与施药技术的关系以及影响农药内吸和传导行为的因素,并提出改善农药内吸和传导行为的措施,以期为农药的安全合理施用提供一定的理论支撑。

The application methods and application efficacy of pesticide are closely related to their uptake and translocation behaviors in the plants.The uptake and translocation behaviors of pesticides on the surface and inside of plants are not only related to the physical and chemical properties of pesticides,but also affected by some factors,such as plants species,growth period,growth conditions and application technologies.The uptake and translocation of pesticides in plants and the influencing factors have important guiding significance for the selection of application technologies and the improvement effective utilization of pesticides.This review summarized the uptake and translocation behaviors of pesticides in the plants,the relationship between conduction modes and application technologies of pesticides,and the factors influencing the uptake and translocation behaviors of pesticides.The measures to improve the uptake and translocation behaviors of pesticides were also proposed,which will provide some theoretical support for the safe and reasonable application of pesticides.
