摘要
本文对稀土影响植物抗逆性、光合作用和对重金属离子吸收、提高作物产量和品质、增强土壤中N、P、K等营养元素的利用与转化、以及稀土在土壤中的存在形态和在植物体内的分布等方面的生理生态效应进行了评述,并指出植物对稀土元素的生理生态适应过程研究中存在的问题。
In recent years, the researchers did many studies on the application of the rare earth in agriculture, and got some achievements. Combining our own study work, we try to give a review about the rare earth′s ecophysiological effect in agriculture from the effect of rare earth on plant resisting environment stress, photosynthesis and absorbing heavy-metals ion, increasing crop yield and quality, enhancing utilization of the soil nutrient element such as N, P and K; and the characteristics of the forms of rare earth in soil and distribution in plant body. And more, some aspects of further research are also proposed.
