TABLE 2.
Research progress on the effects of nutrient elements on Se accumulation in higher plants.
| Added nutrition | Amounts | Crop species | Test results | Se availability | References |
| N fertilizer | 0, 20, 40, 80, 120 kg ha–1 | Rice | The Se and protein content in rice grain increased with the increase of N application, and the grain Se content increased from 0.03 mg kg–1 to 0.35 mg kg–1. | Increase | Reis et al., 2018 |
| N fertilizer | 100, 200 mg kg–1 | Wheat | N fertilizer increased the absorption of Se (VI) in wheat root and the migration of Se to the aboveground. With the increase of N fertilizer, the Se content in grain increased by 22.6 and 12.1%, respectively under the treatment of low and high Se. | Increase | Chen et al., 2017 |
| N fertilizer | 0, 60 mg kg–1 | Wheat | N fertilizer increased the content of wheat grain Se. | – | Duncan et al., 2017 |
| N fertilizer | 0, 40, 80, 120 kg ha–1 | Wheat | N fertilizer increased wheat grain Se content by 17.4, 34.8, and 82.6% with the N content of 40, 80, and 120 kg ha–1, respectively. | – | Klikocka et al., 2017 |
| P fertilizer | 0, 1, 2 g kg–1 | Wheat | Under Se(IV) treatment, Se content and transfer factor of wheat decreased. P fertilizer reduced the content of soluble and exchangeable Se in the soil and increased iron oxide-bound Se or organic matter-bound Se. | Decrease | Zhang et al., 2017 |
| P fertilizer | 0, 1, 2 g kg–1 | Wheat | Under Se(VI) treatment, Se content and transfer factor of wheat increased. P fertilizer significantly reduced the content of iron oxide-bound and organic matter-bound Se. | Increase | Zhang et al., 2017 |
| P fertilizer | 0, 80, 160 mg kg–1 | Wheat | In the presence of Se(IV), the P fertilizer addition significantly reduced the concentration of various forms of Se. | Decrease | Nie et al., 2020 |
| NH4H2PO4 (NH4)2HPO4 |
1.96 g kg–1 2.17 g kg–1 |
Wheat | P fertilizer reduced the content of organic matter-bound and Fe and Mn oxide-bound Se, and increased Se content in wheat | Increase | An et al., 2019 |
| P fertilizer | 0, 240 mg kg–1 | Rice | P fertilizer significantly reduced the Se concentrationin rice grain by 15.2%. | Decrease | Shen, 2017 |
| S fertilize | 0, 20 mg kg–1 | Wheat | S fertilizer decreased the content of wheat grain Se. | – | Duncan et al., 2017 |
| S fertilize | 0, 50 kg ha–1 | Wheat | S fertilizer increased the content of wheat grain Se by 20.8%. | – | Klikocka et al., 2017 |
| S fertilize | 0, 140 mg kg–1 | Rice | S fertilizer significantly reduced the Se concentrationin rice grain by 19.1%. | Decrease | Shen, 2017 |
| S fertilize | 0, 150, 300 mg kg–1 | Rape | S application reduced the Se content in rape and promoted the growth of rape. Sulfur application only affected the Se absorption in root, but not the Se transportation. Sulfur application significantly reduced rape seed Se content by28.2% and 40.4% with the sulfur content of 150 mg kg–1 and 300 mg kg–1 respectively. | Decrease | Liu et al., 2016b |
