本文通过对小麦分别以常乐稀土、富镧稀土进行拌种，并浇以不同浓度的ＮａＣｌ溶液进行培养，然后对小麦幼苗的形态特征和生理指标进行测定。结果表明：用一定量的富镧稀土拌种能够有效地提高小麦的抗盐性，促进幼苗的生长。同时发现，富镧稀土优于常乐稀土 In this paper, Changle rare earths and lanthanum-rich rare earths were drenched into wheat and incubated with different concentrations of NaCl solution. Morphological characteristics and physiological indexes of wheat seedlings were determined. The results showed that using a certain amount of lanthanum-rich rare earth seed dressing can effectively improve the salt resistance of wheat and promote the growth of seedlings. Also found that lanthanum rare earth is better than Changle rare earth
