Rare earth elements are the general name for the group of rare earth elements of the lanthanide series.
The so-called stresses include many, such as low temperature, drought, pests and diseases, salinity, etc. The stresses we have here are Mainly discusses salt stress.
There are currently many studies on salt stress, which mainly refers to the increase in osmotic pressure of cells or tissues leading to the synthesis of anthocyanins. This is manifested in the fact that when plants are short of water, they are more likely to show red leaves. Under this prompt, we can use high-salt solution to treat plants to induce red leaves, but it is easier to damage the plants. Similarly, under domestic conditions, it is impossible for us to use high-saline water for plants, which is another reason why the red leaves are not obvious.
