The invention discloses application of boron in enhancing salt stress resistance of plants. The boron can be an acid, a salt or a derivative thereof, and the concentration of the boron is 0.25-500 [mu] M. According to the present invention, under the salt stress condition, after the appropriate boric acid concentration is added, the toxic effect of the high salt on the plant growth can be significantly reduced, and the plant root system under the high boron treatment and the salt stress environment is developed so as to promote the growth and the development of the plant root system and promote the absorption of the nutrient substance and the moisture. Besides, compared with low-boron plants, the Na < + > content of the roots and the overground parts of the high-boron plants is remarkably reduced, and the K < + > content of the high-boron plants is remarkably increased, so that the Na < + >/K < + > ratio in cytoplasm is reduced, ion balance in cells is maintained within a certain range, and the salt resistanc
