Abstract:Exogenous selenium application could effectively improve the selenium absorption of crops affected by different climatic conditions due to changes in the planting environment and planting conditions. We planted maize at planting densities of 67,500 plants ha−1 (D1) and 75,000 plants ha−1 (D2). Five selenium fertilizer gradients of 0 mg m−2 (Se0), 7.5 mg m−2 (Se1), 15.0 mg m−2 (Se2), 22.5 mg m−2 (Se3), and 30.0 mg m−2 (Se4) were applied to investigate the response of the plants to selenium fertilizer applicatio… Show more
