The nutrient solution culture experiment was conducted to study effects of Se on seedling growth and N,P,Ca content in Italian ryegrass,and seedling growth effects of Se,Si and Se and Si mixed application under N sources (NH4NO3,CO(NH2)2,NaNO3,NH4Cl).

• 通过yoshida溶液培养多花黑麦草幼苗；研究了Se对幼苗生长和N、P、Ca元素含量以及不同氮源(NH4NO3、CO(NH2)2、NaNO3、NH4Cl)下Se(0.；1mg/L)、Si(SiO240mg/L)、Se与Si共施对幼苗生长的影响。
