Abstract：Taking peanut (Arachis hypogaea L.)variety HY22 as material,the effects of 6 mmol /L and 1 2 mmol /L Ca2 + on the plant characters under 1 00 mmol /L NaCl were studied by pot experiment.The results showed that the main stem height,branch number,lateral branch length and biological accumulation signifi-cantly reduced under salt stress;the agronomic characters were improved after applying exogenous Ca2 + and the effect of 1 2 mmol /L Ca2 + was more prominent.It suggested that exogenous Ca2 + could alleviate the inhibi-tion of salt stress on peanut plant growth,improve plant agronomic traits and promot the plant growth.The effect of high concentration of exogenous Ca2 + was more significant.
