摘要
综述了近年来磷素营养与植物抗旱性关系的研究进展 ,指出磷素营养主要通过水分调节、渗透调节、光合调节和根冠生长等一系列生理生长机制来增强植物的代谢活性 ,提高植物抗旱性 ,植物对磷的利用效率与抗旱性也有着密切的关系。
A review with 42 references is given on the recent progress of study on the relationship between phosphorus nutrition and drought resistance of plants.The study results show that through a series of biological and biochemical mechanisms,such as water regulation,osmotic regulation,stoma regulation,photosynthesis regulation and so on,phosphorus nutrition can raise the activity of crop metabolism and drought resistance of plants.ln addition,phosphorus utilization efficiency has close relation to drought resistance of plants.
