The effects of various salt stresses on the plant growth and photosynthetic characteristics of wild rice were studied. The result showed that the low concentration of neutral salt accelerated the growth of wild rice to a certain extent, while basic salt restrained the growth of wild rice; the high concentration of salt stress seriously restrained the growth of wild rice. The effect of basic salt stress was stronger than neutral salt stress. It showed strong negative correlation between plant height, root length, root number, root-shoot ratio, net photosynthetic rate, stomatal conductance, transpiration rate, limitation of stomatal for wild rice and two salt stress degree. The intercellular CO2 concentration was very significant positive correlated with the salt stress degree. The wild rice were still retain a certain amount of the growth and biological accumulation, and showed more adaptable to salt stress.
